Network coding encourages the mixing of information flows at intermediate nodes of a network for enhanced network capacity, especially for one-to-many multicast applications. A fundamental problem in multicast network coding is to construct a feasible solution such that encoding and decoding are performed over a finite field of size as small as possible. Coding operations over very small finite fields...
The use of network coding has been shown to improve throughput in input-queued multicast switches, but not without costs of computational complexity and delays. In this paper, we investigate the design of efficient online network coding algorithms in a switch with multicast traffic. We present Haste, an online opportunistic coding algorithm designed to streamline the computation when network coding...
While it is a well known result that network coding achieves optimal flow rates in multicast sessions, its potential for practical use has remained to be a question, due to its high computational complexity. Our previous work has attempted to design a hardware-accelerated and multi-threaded implementation of network coding to fully utilize multi-core CPUs, as well as SSE2 and AltiVec SIMD vector instructions...
Nowadays, the real practice of network coding in wireline networks is focused on the P2P overlay networks. Although it can help to utilize network resources more efficiently, P2P network coding does not exhibit benefits in terms of the maximum throughput. Our work aims to implement network coding at the IP layer, which is an idea not fundamentally new, but with little real practice because of the...
Although coding over P2P is effective in some ways, coding at routers can bring us more significant benefits. Unfortunately, routers in todaypsilas network are mostly not capable of network coding. We propose a novel scheme to equip routers with coding functionalities. To do this, we design a routing protocol based on network coding and regulate the coding functionalities at routers. Simulation results...
In the paper, we first investigate some properties of capacity factors of a point-to-point network, then give a new upper bound for the maximal cardinality of capacity factors, which is better than the bound in [3]. Finally, we give two definitions of the vertex capacity factors, and present a close relation between the vertex capacity factors and the edge capacity factors.
