This is a combination of an overview of the course, and Internetworking
in general.

Who are we?
o course sponsored by the Student Information Processing Board (SIPB)
o Instructors:
  Elliot Schwartz <elliot@mit.edu>
  John Hawkinson <jhawk@mit.edu>

Internetworking
o What is the problem?
- [picture of a network]
- want people to be able to communicate
- to solve, like any problem, modularity is the key
- break up the problem into smaller problems:
  - how to send packets between adjacent nodes
  - how to send packets between any nodes
  - how to send a reliable data stream between any nodes

Layering
- in fact, modularity in networking tends to be even more constrained
- different "layers" solve different problems
- each layer has a specified interface or abstraction to the ones below
  or above it
- "lower level" layers are closer to the hardware/network
- "higher level" layers are closer to the software/user
