Network

The IPFS Network package handles all of the peer-to-peer networking. It connects to other hosts, it encrypts communications, it muxes messages between the network's client services and target hosts. It has multiple subcomponents:

  • Conn - a connection to a single Peer
    • MultiConn - a set of connections to a single Peer
    • SecureConn - an encrypted (tls-like) connection
  • Swarm - holds connections to Peers, multiplexes from/to each MultiConn
  • Muxer - multiplexes between Services and Swarm. Handles Requet/Reply.
    • Service - connects between an outside client service and Network.
    • Handler - the client service part that handles requests

It looks a bit like this:
