Sponge – TCP Protocol Implementation

This is the implementation of a TCP (Transmission Control Protocol) in modern C++ called Sponge from Stanford University, which helps to establish a bi-directional reliable in-order data transfer between two endpoints on the Transfer layer in term of the 4-layer network abstraction.

Key highlights includes: three-way/four-way handshake(SYN/FIN), segment reordering(stream reassembler), flow control(sliding window), retransmission control(exponential backoff), state transition(finite state machine), etc.
