net-sim

I've always wanted to write some code that simulates networking devices/agents/applications. I guess you leave college but college does not leave you.

Roadmap

Proof of Concept

• Physical Layer: Full duplex unreliable wire
• Physical Layer: Packet capture (.pcapng)
• Link Layer: Ethernet
• Link Layer: L2 Switch
• Network Layer: IP/ARP
• Network Layer: Router
• Transport Layer: UDP
• Transport Layer: TCP
• Application Layer: TCP proxy
• Application Layer: HTTP proxy

Applications and hacks solving problems of the Network Layer

• DHCP
• DNS
• ICMP
• NAT (the hack)
• BGP
