A Multipath Routing Protocol over Chord-based Internet Indirection Infrastructure (I3)

One of architectural proposals for solving the "IP overloading problem" by splitting IP’s "identifier" function out of "locator" function is the Internet Indirection Infrastructure (I3). In I3, a host indirectly communicates with the other by sending data packet, specified by destination's ID instead of the IP address. Although, the I3 architecture overcomes several limitations of the original IP, it suffers in higher performance overhead incurring from the rendezvous place's overlay layer, especially for real-time applications. This study proposed a solution to increase the I3 performance by utilizing more available resources in the Internet using multipath transmission approach. The proposed scheme uses the stacking and redirecting function of the I3 to intercept the data packets injected at the sender local server. Then, those data packets will be distributed through several possible paths toward the receiver local server where the data will be forwarded directly to the receiver. Both local servers will cooperate together to dynamically search for available paths via I3 servers according to the network condition on the Internet. Based on simulations, the results suggest that the proposed scheme can significantly improve the I3 performance even in environments with mobile hosts.
