public class RelaySession
extends MediaProxySession

A Session Class will control "receive and relay" proccess. It creates UDP channels from Host A to Host B and from Host B to Host A using or NOT the specified hosts and ports. The IP and port pairs can change depending of the Senders IP and port. Which means that the IP and port values of the points can dynamic change after the Channel is opened. When the agent receives a packet from Point A, the channel set the point A IP and port according to the received packet sender IP and port. Every packet received from Point B will be relayed to the new Point A IP and port. When the agent receives a packet from Point B, the channel set the point B IP and port according to the received packet sender IP and port. Every packet received from Point A will be relayed to the new Point B IP and port. Create a dynamic channel between two IPs. ( Dynamic Point A - Dynamic Point B ) It has 4 Channels. 2 for data and 2 for control.
