Assignment: TCP Implementation
A new tar-ball is provided with a solution to the previous assignment. If your solution is similar to the one presented, you may choose to continue on with it; but it is suggested that you untar the new project files in a fresh working directory:
tar xvzf <tar-ball location>
Transmission Control Protocol
Standard number 7 of the Internet Official Protocol Standards is the Transmission Control Protocol. In this assignment students will build the Transmission Control Protocol into Embedded Xinu by defining a stream device that uses Embedded Xinu device paradigm.
Upon completion of the assignment the students' implementation should:
Required Assignment Parts
- send and receive packets of with type TCP
- determine the status of a specific datagram device and place desired data in its stream buffer if applicable
Optional Assignment Parts
- shell integration: add a tcp-con command to the shell (establishes an active or passive TCP connection)
If you choose not to implement the optional assignment parts then placing test case code within the shell's 'test' command will allow you to run one or more tests on your implementation at run-time. Optional portions to an assignment may be required portions of a later assignment.
Upon completion of this assignment students should understand the key role this protocol plays in the overall networking architecture. Each student should also be able to understand how streams as devices fit into the operating system and the overall networking architecture.
