Abstract
A coding approach for a robust and flexible network communication protocol is described. By using coding, it is possible to eliminate the need to track packet identities, and hence, it is possible to reduce coordination overhead associated with many conventional protocols. The method and system described herein takes advantage of multiple paths, interfaces, mediums, servers, and storage locations available in a network. The proposed protocol allows quick response to congestion by load balancing over different network resources. The method also enables soft vertical hand-overs across heterogeneous networks. In one embodiment, a media file is divided into chunks and transmitted using a transport protocol tailored to meet delay requirements of media streaming applications. Also described are different coding strategies for chunk delivery based upon an urgency level of each chunk.
