Core/Periphery Network

I consider this a core pattern:

"The end-goal for vibrant, sustainable community networks is the core/periphery model. This topology emerges after many years of network weaving by multiple hubs. It is a stable structure that can link to other well-developed networks in other regions. The network core in this model contains the key community members, including many who are network weavers, and have developed strong ties between themselves. The periphery of this network contains three groups of nodes that are usually tied to the core through looser ties:
1) Those new to the community and working to get to the core
2) Bridges to diverse communities elsewhere
3) Unique resources that operate outside of the community, and may span many communities.

The economic landscape is full of imperfectly shared ideas and information. The periphery allows us to reach ideas and information not currently prevalent in our network. The core allows us to act on those ideas and information. The periphery is the open, porous boundary of the community network. It is where new members/ideas come and go. The periphery monitors the environment, while the core implements what is discovered and deemed useful."
