Directory simple-echo includes a simple tcp echo server & client

Directory lib includes the params package required for many of the programs

Directory stammer-proxy includes stammerProxy, which is useful for demonstrating and testing framing

Your task: develop and implement a protocol to frame byte-array messages in a manner that they will arrive intact even if they are fragmented during transmission.

• stammerProxy.py forwards tcp streams. It may delay the transmission of data but ensures all data will be forwarded, eventually. By default, it listens on port 50000 and forwards to localhost:50001. Use the -? option for help.
