Network Protocol Myths

Share

The main point of this lecture is to encourage critical thinking.  So much of what “everyone knows” about network protocols is, actually false.   For instance, why do we need both Ethernet and IP?  The “obvious” answer is that IP is “layer 3” and Ethernet is “layer 2”, but in fact, once Ethernet stopped being a single wire (layer 2), and something that is forwarded (layer 3’s job) it became a layer  3 protocol.  So the right question is “why do we use to layer 3 protocols?”  The answer is subtle and leads to discussion of how Ethernet became a “layer 3” protocol, and evolution to TRILL and other overlay networks.  There are also buzzwords such as “SDN”, and fads such as “active networks” and “information-centric networking”.  This talk will demystify these, as time follows.
