“…The use of coding has also been proposed before our work or that of [3] in order to mitigate the effect of losses on TCP, particularly in the context of wireless links. We may roughly taxonomize these into approaches that consider the operation of TCP jointly with lower layer redundancy, at the physical or MAC level, often in a cross-layer approach [1,[4][5][6][7][8][9][10][11][12] and those that consider redundancy at the IP layer or above without access to the lower layers [13][14][15][16][17][18][19]. Since our goal is to provide a system that operates without access to, or even detailed knowledge of, the physical layer, it is in the latter category that our approach belongs.…”

We introduce CTCP, a reliable transport protocol using network coding. CTCP is designed to incorporate TCP features such as congestion control, reliability, and fairness while significantly improving on TCP's performance in lossy, interferencelimited and/or dynamic networks. A key advantage of adopting a transport layer over a link layer approach is that it provides backward compatibility with wireless equipment installed throughout existing networks. We present a portable userspace implementation of CTCP and extensively evaluate its performance in both testbed and production wireless networks.

“…Attempts to reduce the number of retransmissions required and maintain a stable throughput can be aided by combining FEC with TCP [10], the combination of which guarantees delivery of the video content with perfect quality, although at a reduced throughput when packet loss is experienced. Conversely, if one is to use UDP solely, there is no additional delay inherent with TCP re-transmissions, however packet loss is uncontrolled and can cause significant picture degradation.…”

In this paper we propose a hybrid TCP/UDP transport, specifically for H.264/AVC encoded video, as a compromise between the delay-prone TCP and the loss-prone UDP. When implementing the hybrid approach, we argue that the playback at the receiver often need not be 100% perfect, provided that a certain level of quality is assured. Reliable TCP is used to transmit and guarantee delivery of the most important packets. This allows use of additional features in the H.264/AVC standard which simultaneously provide an enhanced playback quality, in addition to a reduction in throughput. These benefits are demonstrated through experimental results using a test-bed to emulate the hybrid proposal. We compare the proposed system with other protection methods, such as FEC, and in one case show that for the same bandwidth overhead, FEC is unable to match the performance of the hybrid system in terms of playback quality. Furthermore, we measure the delay associated with our approach, and examine its potential for use as an alternative to the conventional methods of transporting video by either TCP or UDP alone.
