P2p source code and several packages below

• Discover contains theKademlia protocol. It is a UDP-based p2p node discovery protocol.
• Discv5: new node discovery protocol. Still a test proposal. This analysis is not covered.
• Part of the code for nat network address translation
• Netutil: some tools
• Simulations simulation of p2p networks. This analysis is not covered.

Source code analysis of the discover package

• Discovered nodes for persistent storage database.go
• The core logic of the Kademlia protocol is tabel.go
• UDP protocol processing logic udp.go
• Network address translation nat.go

p2p/ package source analysis

• Encrypted link processing protocol between nodes rlpx.go
• The processing logic to select nodes and then connect them.
• Processing of node and node connections and handling of protocols peer.go
• Logical server.go for p2p server
