Programming Assignment 5: Implementing a Reliable Transport Protocol In this laboratory programming assignment, you will be writing the sending and receiving transport-level code for implementing a simple reliable data transfer protocol. There are two versions of this lab, the Alternating-Bit-Protocol version and the Go-Back-N version. This lab should be fun since your implementation will differ very little from what would be required in a real-world situation.
