extends AutoCloseable, io.netty.channel.ChannelInboundHandler

BGP Session represents the finite state machine in BGP, including timers and its purpose is to create a BGP connection between BGP speakers. Session is automatically started, when TCP connection is created, but can be stopped manually via close method of the Closeable interface. If the session is up, it has to redirect messages to/from user. Handles also malformed messages and unknown requests.
