All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler

@UnstableApi
public class TcpServer
extends io.netty.channel.ChannelDuplexHandler

Starts a TCP-based server, allowing clients in very restrictive networks that do not allow UDP-based traffic to connect to this super peer via TCP.

This server is only used if the node act as a super peer.
