When a computer router receives a message... grey areas I want to stress that networks do not happen in-andof themselves, and it enhances our understanding of networks to understand the context or environment in which they exist We’ll also note that some of the features of systems influence and direct the coming together and falling apart of networks Distinction: systems are networks that have api’s for other networks (social network vs social... are not designed to broadcast ~ 19 ~ Weaving Networks every message, they are more like airline hubs, which are designed to route traffic to specific destinations Hubs arise naturally in the nature of any kind of network There are a few popular books about networks that talk about hubs like LINKED by Albert-Lazlo Barabasi, NEXUS by Duncan Watts and other books on networks that you might find interesting... general attitudes and dispositions Boundary spanners People do not exist only in networks and clusters either They exist in multiple networks You have family, friends, neighbors, co-workers, exes and so on, so you live in multiple networks me people, you could say, specialize in being members of many different kinds of networks These people belong not to one particular group, but many groups Think of... AT&T about the feasibility of what we now know as digital networks AT&T was against even the possibility of digital networks as its own equipment at the time was all-analog You think moving from analog to digital television was something? Imagine how hard it was, or would be, for the whole phone 3 Reproduce the network diagrams ~ 11 ~ Weaving Networks system! Paul Baran was hired by the RAND corporation,... these networks and systems require some software program, group or person to decide exactly what route each plane, train or message takes to get across the network and between sub -networks Bridging internetworks We know from one of the first sections that the guys at ARPA created a network of computers mewhere near the end of that section I mentioned that later they connected that network to other networks. .. train ~ 25 ~ Weaving Networks station are also in radio communication with the train conductors to exchange information about routing, timing and so forth The same thing goes with air traffic It even happens on the roads with road signs for general traffic and turn signals (sometimes) as communication between entities on the network THINKING ABOUT NETWORKS there are some other features of networks that... exactly mean that the reason it exists is obvious we’ll get into the theory of networks to start to explain the technical aspects of the growth and structure of networks What we’ll be talking about is how networks come to exist, versus not forming at all One of the main questions in network theory is how do they happen? What causes networks to be created versus having lots of independent nodes? Well, if... any preference toward retaining links longer than others will create networks and clusters out of a random bunch of nodes Now, there’s a lot of math behind figuring out at what threshold networks form, clusters form, networks and the like But we are not worried about that What we are concerned with is simply the birth and growth of networks from, well, no links In the real world, researchers have found... intranets an internet And ~ 13 ~ Weaving Networks obviously, when we internetwork multiple internets, we call it ‘the Internet’, as opposed to ‘an internet’ FEATURES OF NETWORKS [Nodes, links, hubs, routers, shapes, internet] We are done with the time-lapse history lesson on the birth of the internet Now we are going to comb through the information to explain some of the details of networks and networking I .
