Paper Abstract

The Access Grid (AG) is a multi-party collaboration environment, where efficient media exchanges among remote participants are supported by IP multicast. However, due to limited availability of native IP multicast service, application-assisted multicast connectivity solutions are required in real operation of the AG. Recently, we have proposed a UMTP (UDP Multicast Tunneling Protocol) based solution, named as AG Connector, which takes advantage of UDP-based tunneling approach. In this paper, we extend this original AG Connector solution by addressing multiple UMTP server coordination and other operational issues. The proposed extended multicast connectivity solution can support increased number of AG nodes that even include nodes under NAT/Firewall-based private networks.
