1. When computer programs running on two packet switches exchange distance-vector information, the programs must agree on a message format. Create a specification for an unambiguous message format. (Hint: consider differences in the way computers represent information.)

2. Extend the previous exercise by implementing a computer program that uses the specified message format. Have another student implement a program from the same specification, and see if they interoperate correctly.
