METHOD FOR UDP MULTICAST TUNNELING IN MULTICAST-BASED MULTI-PARTY COLLABORATION ENVIRONMENT, AND SYSTEM THEREFOR

摘要

A method for UDP(User Datagram Protocol) multicast tunneling in a multicast-based multi-party collaboration environment, and a system therefor are provided to secure the stability of multicast connection by controlling a UMTP(UDP Multicast Tunneling Protocol) agent to be connected with another UMTP server when the connection between the UMTP agent and the UMTP server is released. A method for UDP multicast tunneling in a multicast-based multi-party collaboration environment includes the steps of: generating a UMTP server registration list by receiving registration information including an IP address and port information in a UMTP registration server from a UMTP server(S200); receiving the UMTP server registration list in a UMTP agent from the UMTP registration server(S220); checking the possibility of connection with the UMTP server included in the UMTP server registration list by the UMTP agent(S230); and attempting the connection with any one UMTP server included in the UMTP server registration list by the UMTP agent, and generating a UDP tunnel(S240,S250).
