Cable Labeling

It is very important to give labels to your cables. Labels make your network troubleshooting less painful. In case of problem, you don't want to trace every cable end to end.

Each end of cable should be labeled, the label should give information about where the cable is connected to.
It is really up to you or your company policy how the description format of the labels should be written.

The most important thing is to keep the writings not too long, and easy to be interpreted. For example, I have a fiber optic cable at the IDF going to the MDF, I like to name it like this:

for the IDF cable: MDF_Core1_23 -> it tells that the cable is going to the MDF Core Switch 1 at port 23.
for the MDF cable: IDF_2Fl_1_1 -> it tells that the cable is going to the IDF at second floor, switch 1 and port1.

Well I suggest try designing your own labeling scheme and don't forget to write it down and give the description to fellow network installers and the project owner.

You can use many tools for your labeling, there are many tools to make your labeling easier, some tools will keep track on your labels and generate the next label automatically while some tools require us to input the label writing manually.
Below is a variety of tools you can use for your labeling purpose, you can find a lot of tools available at my favorite site http://www.cableorganizer.com.


Network Segmentation

You started your network with small amount of computers and networking devices, sooner or later you want to add this and that, next thing you know your network got slower.

If you have this condition in your network, you might want to consider reviewing back you what devices you have in your network. You might need to segment your network.

You can use switches and bridges to segment your network, if you use them you separate your network collision domain. Remember what collision domain is when I posted about switches.


Like the above picture, if you use switch to connect 4 computers, then you'd have 4 collision domains. On the other hand, if you use hub, then you'd have 1 big collision domain, this will not only slow your network but also pose security problems.

The above picture looks good, but they're still count as one broadcast domain. To break up broadcast domain you can use routers.


What broadcast means is that computers need to send packet all over the network. One example is when you use DHCP to give IP address to all computers, first the computers will send out DHCP Discover message everywhere saying, help I don't know my IP, can anyone give me one?
The fact that computers send a lot of broadcast when connected to a network, the more computers/broadcasts you have, the slower your network will be.

 
When using router to break broadcast domain like this, this means you'd have 2 broadcast domains, in other words, you have 2 network segments within your network.
In CCNA exam, they usually give questions like this, if you have a network with the diagram like the above picture, how many broadcast domains and collision domains exist?
You know you have 2 broadcast domains, but how many collision domains? 
Remember each port in a switch forms one collision domain and routers also the same.
From the above we can tell that the diagram has 6 collision domains.

Seriously Rethinking Leadership in a Networked World

For over 30 years, I have had the privilege of helping leaders around the world develop their leadership effectiveness. In dozens of sectors and markets, I've seen the best and worst.

I continue to see established and emerging leaders who are passionate about learning to be better leaders and entrenched leaders who view learning as a threat to their power.

In these interesting times, we are witnessing an abundance of leaders who are devastating the integrity of markets and the faith of their constituents. Many countries have what Will Rogers referred to as "the best government money can buy." It is easy to find leaders who define leadership as the exercise of control over money and people.

At the same time, the planet is abundant with leaders who are helping to make their communities stronger and more resilient. They have intelligence, wisdom, and transparency. They see themselves more as stewards of resources rather than controllers of money and people. They think that leadership is more about helping people find their power than having power over people.

But are these the qualities of good leaders? Perhaps the only thing we can accurately say about leadership is that every assessment is based on personal bias.

For some people, good leaders serve their interests at the cost of serving competing interests. They like weak leaders they can control with money, votes or threats to their power and influence. Others like strong leaders who exercise control over others. They like leaders whose rule guarantees certainty in their favor.

Whether we want leaders who are children capable of being controlled or parents capable of protecting us, what both perspectives have in common is that they are essentially self-serving. They position leaders as tools to our agendas.

And because we are still transitioning through a predominantly adolescent consciousness on this planet, there are almost always competing agendas. In this ethos, we impose on leaders the unfulfillable expectations to guarantee the dominance of our agendas over opposing and hopefully loser agendas.

The opposite of viewing leaders as tools to use is viewing them as assets to engage in our networks. The two most valuable assets in networks are knowledge and skills.

In this worldview, leaders have unique value to the extent that they have unique knowledge and skills in their networks. Their networks include everyone they directly interact with and influence. Leaders who lack unique value have redundant value in their network.

The more connected networks become, the more likely it is that leaders have redundant value. This is one dimension of the leadership crisis today, exacerbated by the fact that the more asset redundant leaders become, the more irrelevant they feel and the more control they exert to restore ego equilibrium.

Reality is, in networks leaders can gain unique value in at least two ways. They create unique value when they create a niche of unique value for themselves. And they gain unique value when those in their network intentionally leave them a space of value uniqueness that no one else takes on.

This is a huge culture shift to see the value of leaders as equivalent to the uniqueness of their real time knowledge and skills relative to their networks. It is a shift that requires us to question the value of positional power that leaders assume in their leadership roles.

Positional power is the assumed power to control money and people. We have abundant and growing evidence that it takes no unique network value to exercise control over money and people.

Scope of control has nothing to do with unique value in a network. If scope of control had any causal relationship to scope of unique value in networks, monarchs, autocrats, and dictators would be guaranteed the most unique knowledge and skills in any networks at any levels around the world.

Understanding leadership through the lens of unique network value profoundly changes the conversations we have when we interact with leaders in our networks at the relative levels each of us has access to these kinds of interactions.

It becomes imperative that everyone understands the unique assets of their leaders. Before they enter any leadership position, we need to gain a collectively clear and accurate picture of their unique and redundant assets relative to our and their networks. When they enter these positions, we need to make it collectively clear what unique assets they have that the thrivancy of our networks require. We also then need to negotiate the areas of asset uniqueness they would provide the network.

But because of the intrinsically dynamic nature of networks, their relative asset uniqueness and possibilities of uniqueness constantly shifts and changes as other people in the network expand their unique value, making the leader's assets redundant, but still possibly quite valuable. Asset redundancy at optimal levels is key to network resiliency.

Networks are also constantly shifting landscapes of opportunities and expectations and so leaders always have opportunities to grow their unique assets to meet these. And this emphasis on asset and network based leadership makes it immediately more possible for leaders across boundaries to collaborate more successfully and intelligently to do together what they cannot possibly do alone, apart or in opposition.

This is an incredibly important shift if we seek a world where leaders help build thriving communities at micro to macro levels.

In this construct, perhaps the most salient characteristic of network relevant and valued leaders is that they have a passion for knowing their networks and continuously reinvent the unique value in knowledge and skills they bring to their networks.

This calls for a profound shift in how we develop, select, and assess our leaders. And the time to begin is now.

Mapping Twitter Chats


This is a network map of the almost 1000 tweets during the #ideachat 1 hour session in November 2010. Individual participants in the chat are shown as purple nodes and the "whole group" is shown as the large green circular node. If someone tweeted to everyone in the group, at least twice in the session, an arrow would be drawn from their node to the big green node. People who tweeted to each other [@ messages or RTs], at least twice in the 1 hour session, will have arrows drawn from the tweeter node to the subject node. @blogbrevity <--> @cocreatr indicates that they both sent 2 or more tweets to each other during the session. [We do not show the hundreds of single tweets in the session -- we are looking for key participants.]

Node size on the network map reflects a new network metric we are experimenting with called "attention" which tries to determine both quantity and quality of links pointing at someone. It's not just the number of tweets pointed at you, but who they come from that matters. We will also post an interactive version of this map that will allow you to filter on the type of tweets and their timing during the 1 hour session.

From: blogbrevity's posterous Thanks, Angela!

9 Indicators of Growing Networks

We continue to have countless conversations with funders and others who want to "grow" networks of collaborations and innovations. This is impossible until they have enough network literacy to understand what it means that a "network" actually "grows."


Here are 9 simple indicators of network growth, to this purpose. They become both indicators and strategies for the intentional growth of existing networks.

  1. People in the network gain broader and deeper awareness of the available assets in the network
  2. People in the network gain broader and deeper awareness of potential new collaborators and co-conspirators in the network
  3. People in the network spend more time introducing people to one another who are 2+ steps away from each other in the network
  4. People in the network spend more time introducing themselves to others who are 2+ steps away from them in the network
  5. People in the network discover more new opportunities to engage and combine their assets to create a future different from the past
  6. People in the network have more conversations together about their dreams and assets than their problems and deficiencies
  7. People in the network value change and differences as more valuable to the network's growth than similarities and protecting a status quo
  8. People in the network become "network weavers" who intentionally commit time and imagination to looking for new ways to connect unconnected people in the network
  9. People in the network together become more self-organizing, innovative, agile, inclusive, strengths-based, and dedicated to shared thrivancy

Killing our Neighborhoods


I wonder if a Goldman Sachs executive would spend a night in the house above? After all, they do kind of "own" it.

The house, in the Slavic Village neighborhood of Cleveland, had a mortgage that was part of the Goldman Sachs synthetic CDO, ABACUS 2007-AC1. In 2008, the house was foreclosed upon, and still sits abandoned today.

At least the ivy devouring the south side of the building seems happy.

I am writing this in the Red Chimney restaurant, a social hub for the locals in Slavic Village. This place is probably the only thing that has not changed drastically in the last ten years in this neighborhood. It feels very comfortable -- old networks get rejuvenated here. Every community needs a gathering place, especially in times of trouble.

For an in-depth look at the players and financial flows involving this house , see Connecting the Dots of the Mortgage Meltdown.

Valdis recently helped CNBC with a documentary about Goldman Sachs and the recent mortgage crisis.

What is A Network Weaver?

A Network Weaver is someone who is aware of the networks around them and explicitly works to make them healthier (more inclusive, bridging divides). Network Weaversdo this by connecting people strategically where there's potential for mutual benefit, helping people identify their passions, and serving as a catalyst for self-organizing groups.

If you at at the NTEN conference, or want to think about what it means to be a conscious Network Weaver at any conference, check out the Google Doc we created to gather what we learn. We are particularly interested in learning what it means to witness others being Network Weavers. How can we notice and support people who are natural Network Weavers?

The possibilities of a networked commons


What if we invented an approach to democracy where voting was not a design element in the model. Voting continues to be the root cause of unchallenged excesses, bad decision making, special unethical interests, and leadership incompetence.

In most cases, voting is an excuse to avoid conversations that are information-based, inclusive, and innovative. There is no wisdom in crowds of weak networks. Managing assets in the commons can happen in strong networks of people as long as the commons are at the scale of networks where the degrees of connection are relatively close. In these networks, people come together to create commons they manage through conversations that matter. A very different world indeed.

Overlapping Boards

We often think of our networks as belonging to us, or our group/team/family. We imagine they have an identifiable beginning and end. We want to draw borders to define "yours" and "mine." Yet, in reality we cannot. We really cannot define where my network stops and yours starts... no matter if you are a person, group, organization, or country. We are all intersected and our connections overlap with those of our network neighbors. Boundaries are fuzzy, at best.

Let's look at a simple example. Organizations, whether for-profit, or not-for-profit, usually have a Board of Directors. We can think of this Board as a network that belongs to the organization. All members are linked if they sit on an organization's board together. We might view the Boards of the top 50 U.S. companies like the diagram below -- individual clusters, each belonging to the parent company. The gray links show co-membership ties between the individuals.


Directors are not limited to the number of Boards they can be members of. Board members are limited to the number of Boards they sit on only by time, energy and invitation. Below is an example of a Board member who sits on the Board of two organizations. This may be Steve Jobs, who sits on the Board of Apple and Disney.


We now choose a different color for those Directors who sit on multiple Boards. We see how the Boards of the top US companies are actually interconnected in the diagram below. Blue nodes are Directors who sit on multiple Boards.


The blue nodes in the network above are conduits that move information, ideas, and knowledge between the clusters -- they are at the intersection, where two networks overlap. The blue nodes are well placed to be Network Weavers -- their opportunity to close triangles is great.

Contagion of ideas and practices between organizations often happen through flows via their Boards of Directors. We apply social network analysis [SNA] to this social graph and we see who may be key in this diffusion process. We apply a new SNA metric, called Awareness -- it measures potential awareness of a node to what is happening around it [directly and indirectly] based on it's pattern of connectivity. Those nodes with higher awareness are shown in a larger size in the diagram below.


It is usually beneficial to be connected to those who have a good view of what is going on. Information and knowledge is often shared [intentionally or unintentionally] with trusted others, close by. Information leaks and flows, but never too far. Board members who are connected to other highly-aware Board members, have a higher probability of finding out more -- but the range is limited. Even those who just sit on a single Board can increase advantage by being connected to multiple blue boundary spanners. This is reflected in the diagram below. Node size is derived from awareness of what is happening in the network. Some Boards have greater awareness of what is happening in their ecosystem.


This was a simple illustration. An actual network between the Board members will be denser, based on their possible multiple ties -- employment, memberships, and other current & past associations. The full multiplexity of the individuals was not known, nor shown. Yet, we see how even some knowledge of a social system increases our potential to target messages to influence that system. Of course, the better our data, the better our targeting. A telescope may be preferred, but even binoculars provide advantage over the naked eye. And binoculars that reveal what is usually invisible, are even more useful!

What Board overlaps can you utilize?

Network confidence

As networks grow, they grow in confidence. Confidence is the expectation of success and comes from thousands of small acts of success within and across networks.

These small acts include solving common problems and problems in common together and sharing learning, knowledge, opportunities, talents and resources together. Every instance of success adds to the network's collective self-confidence that incubates even more collaborations and successes, resulting in "virtuous spirals" of thrivancy and thrivability.

And of course, the narrative culture within networks accelerate and scale ripples of confidence throughout the network and beyond to other networks.

The 4 Developmental Stages of Networks

June, Valdis and I have seen countless networks grow over the past 30 years. It's interesting to see networks grow from weaker to stronger. They go through four stages in the process. Here is a model based on the phases of human development. When we bring people together in their networks, we see all four stages within various connections in the network.

Best of all, unlike human development where phases cannot be skipped, effective network development can involve immediate acceleration to an emerging and scaling network of adult connections.

Infancy
People in the network feel dependent on formal leaders to make things happen in the network. Their whole life is structured around demands that parent leaders take care of all their needs. Their whole thrivancy is based on the trade of compliance for protection.

Childhood
People in the network are interested in making things happen, but only things that require permissions and funding from the parental formal leaders. They are focused in this phase of getting more support from parent-leaders for the things they want to do. They live in continuous demand from a position of entitlement.

Adolescence
People in the network give up dependency on their parent-leaders, but still believe the "pie of resources" is still finite and so compete with peers to satisfy their needs. In this phase, people in the network believe that others' loss is the necessary cost of their gain.

Adulthood
People in the network take responsibility for their destinies and know that working together expands the pie in ways that allows everyone to thrive. They believe that people in the network can achieve more together than they ever could apart or in opposition.

Network weavers help people move into the adult phase more quickly and successfully, accelerating the possibilities of more strong networks.

Need Help with Network Weaver Handbook


As you may know, I've been working on a Network Weaver Handbook for some time now. I've got almost 100 pages of activities and stories that you will be able to use with your networks, and I think it will end up around 200 pages before I'm through.

But right now, I need your help!

I have loaded the Table of Contents in a google doc and hope you will click on the link to the page, then add comments, questions, edits, etc. Here are some questions:

1. Which part looks most interesting or exciting to you?

2. What is missing that you would like to see included?

3. What is included that you don't think is that important?

Thanks so much for working with me on this!

How to Create a Sandbox for Learning




Beth Kanter and I met at a workshop for foundations last fall. She loved the concept of Network Weaving and we decided to spend some time figuring out the synergies between Network Weaving and social media. We decided to use a call line she had but Skype would work as well. Meanwhile, she set up a little exercise for us to do, which she described on a google doc she set up.

Exercise:

1. Create 3-5 slide powerpoint with photos that defines/explain network weaving and your key ah ha from session
2. Upload into SlideShare
3. Put in the Network Weavers Group
4. Comment on someone elses slides
5. Create a new deck based on feedback and/or remixing the other person's

I invited a friend. Good thing as Deborah was the only one who did the assignment! Beth then took us to www.flickr.com and showed us how to search the Creative Commons (free to use) pictures there. She was sharing her desktop but letting us make decisions about what pictures to use. It was lots of fun! We noticed the power of slides with only a few words � the image was what had the power to help people get new concepts.

I went back and made a new deck, using yarn and knitting images to represent network weaving and feeling a great sense of accomplishment. We invited several addition friends to the next session, and it was great to meet some new people. We got on Slideshare again and Beth talked about how people loved puppies and babies and so we made a deck using images of kids. Beth always had us spend the last half hour reflecting on what we had done. This time we noted the importance of helping people make an emotional connection to concepts to help them better remember and apply them.

In the next few sessions, a major shift took place. Someone else helped set up the next time using www.doodle.com. At each meeting, we�d decide what we wanted to learn or talk about. Sometimes we explored new social media: Google Wave, web-based project management, etc Sometimes we had clinics, where one person asked for advice. Sometimes we spent most of the time deeply introducing ourselves to each other. But what ever we did, we laughed a lot, appreciated each other and reflected on what we had learned.

After Beth�s initial guidance, there was no designated leader, not even a coordinator: we all took responsibility for making sure the needed tasks got done, we all took notes together (which is possible on google docs), and we took turns facilitating as needed (watching the time, making sure we spent time on reflection). This kind of collaboration can work!

I encourage others to start a sandbox of your own. All you do is invite a few friends to a skype call and figure out what you want to learn or do together. Let me know how it works out!

Structural Folds and Innovation Dynamics

A recent article called Structural Folds: Generative Disruption in Overlapping Groups , by Balazs Vedres and David Stark is chock full of important research on innovation, collaboration and networks.

Vedres and Stark studied relationships among businesses in Hungary over the last 20 years. In contrast to Ron Burt�s concept of structural holes, they explore the concept of structural folds.

The concept of structural holes describes how individuals who span two different clusters or groups can become powerful by brokering the relationships and information flow across the clusters. Managers who span structural holes often move quickly up the corporate ladder.

Using the concept of structural folds, Vedres and Stark argue that moving ideas from one cluster or group to another is not enough to spawn innovation. Groups need to overlap. They need to recombine and do something together to generate innovation that leads to growth. However, this overlap is often disruptive, and can lead to disintegration of the groups.

The trick is to move to another level, looking at the whole set of groups as part of a larger network. Then you can see that the larger network has some stability over time � individuals or businesses continue to be part of this larger network, but are recombining with others in different configurations over time. This looks disruptive, but is actually the source of much creativity and growth. The larger network, meanwhile builds a culture of collaboration that encourages and supports even more collaboration.

These ideas are very compatible with our Smart Network model. A Smart Network has a core of overlapping clusters. Clusters could be different organizational types (such as entrepreneurs, non-profits and foundations), different geographies, different business sectors, etc. In most Smart Networks, people are recombining through self-organized, collaborative projects. Vedres and Stark remind us that it�s important that these projects contain at least several people who have worked together before, but that including new faces from different clusters is likely to increase the success and growth of the project.

Using the Opportunity Process to Catalyze Self-Organization


How do we get started with self-organization?

One simple process (adapted from a Peter Block activity) I've used many times is the Opportunity Process. Here's the simple steps:

1. Have people put their interest or current passion or challenge on a 9 x 12 sheet of paper or PostIt. Have someone sort into Action Groups of 3-10 people.



2. Have each group identify opportunities in that area where something could really make a difference right now.

3. Generate ideas for small projects/small acts that could help the group explore that opportunity. Each act needs a champion.

4. Identify the gifts (skills and resources) that the project team already has to accomplish that act.

5. Figure out who and what else they need to make the project successful and then invite those individuals to join their project.

6. How will the project be managed? Use a project management worksheet or online project management site like TeamworkPM so everyone involved knows what they are to do. Have a volunteer be project coordinator.

7. Check in with and coach the project coordinators.

8. After the project is underway, identify �patterns of success.�

Economic growth indicators for networks

Networks can actually envision and measure their economic growth impacts on communities and regions and network spaces. Here are just a few indicators that can consider:
  1. Number of new college-degreed & non-degreed jobs created by current organizations in each sector
  2. Number of jobs created by new organizations in each sector
  3. Number of new organizations coming to locate here from outside in each sector
  4. Number of new organizations started from within the community in each sector
  5. Number of new product and service lines offered by community organizations in each sector
  6. Number of people in the community less or no longer dependent on public services and aid in each sector
  7. Number of businesses performing better in each sector
  8. Number of organizations with successful strategic processes in each sector
  9. Number of residents with increased housing value in each sector
  10. Number of students graduating to the next levels in each sector
  11. Number of students starting new businesses and organizations in each sector
  12. Number of employees re-skilled for new industries in each sector
  13. Number of consumer dollars shifted from non-local businesses to local businesses in each sector
  14. Number of businesses and organizations shifting to local suppliers in each sector
  15. Number of people whose health care, education, and energy costs have decreased in each sector
  16. Number of children with reading, writing, research, financial, and cultural literacies in each sector
  17. Number of older citizens living longer and with few costs of living in each sector
  18. Number of employers satisfied with the local pool of talent for open positions in each sector
  19. Number of organizations winning grants, awards, and funding for local projects and efforts in each sector
  20. Number of occupied commercial and retail spaces in each sector
  21. Number of employee owned businesses that spawn new businesses
