Toy TCP-IP Stack

This is a project based on modern C++ and Stanford's sponge library.

This project mainly followed the following steps of development:

1. develop a simple bytestream abstraction

2. develop a reassembler to reconstruct datagrams into bytestream

3. develop a TCP receiver to handle incoming bytestream

4. develop a TCP sender to slice outgoing stream into datagram payloads

5. combine TCP receiver and sender

6. implement ARP to map from IP addresses to Ethernet addresses

7. implement a simple router to keep track of a routing table and forward package
