In this week we covered a variety of fundamental application protocols. Each protocol showed an example of how you can use networking to accomplish different goals. HTTP as it compared to FTP shows the use of multiple ports versus a single port during an applications life cycle. Another difference that came up was using a p2p network topology compared to a client-server relationship. Using that kind of organization can let you increase survivability with off grid mesh networks which interests me. Also I don't like moving information through unnecessary nodes.
One of my favorite p2p products is
gotenna. It just seems like a great idea for people to have their own cell phone base stations that create a network like that.
goTenna (goTenna Inc.) is a
Brooklyn, New York-based
startup that designs and develops technologies for
off-grid and
decentralized communications. goTenna devices pair with
smartphones and, through intelligent
mobile ad hoc networking protocols, enable users to send
texts and share locations on a
peer-to-peer basis, foregoing the need for centralized communications infrastructure of any kind.

I don't have one of these products, but they do seem like an interesting way to augment peoples cell phone capabilities.
As for the networking assignments this week they helped continue the process of dividing the path information takes from one place to the next into visible pieces. I really like to be able to see things physically so packaging up packets and moving them through different layers is attractive to me. It will be nice to have a very solid view of information moving across space at different levels of abstraction eventually.
