It is a well known result that network coding may achieve better network throughput in certain multicast topologies. However, the practicality of network coding has been questioned, due to its high computational complexity. This paper represents an attempt towards a high performance implementation of network coding. We first propose to implement progressive decoding with Gauss-Jordan elimination,...
A dynamic policy based network management scheme is presented for the problem that traditional policies can??t preferably adapt to change of network state. It defined dynamic policy form and appended new module PMA to IETF policy frame to improves the adaptability of policie. Then the application of dynamic policy to allocate resource is presented. By experiment and analysis, it is shown that this...
P2P workflow systems meet the development trend of workflow systems. The running path optimization (the path with the minimum running time which consists of the services discovery time and the task execution time) in full-distribution (decentralized) environments has been a bottleneck restricting the performance of P2P workflow systems. Aiming at this problem, this paper proposes a innovative hybrid...
P2P together with media streaming technology brings a new method for video service. This paper proposes a design to deploy video service on commercial systems with authentication servers. The design combines C/S charging model, and provides video contents in a P2P way. According to the address information registered on authentication servers, a media management server helps new peers to find their...
NS2 is an object-oriented simulation tool to simulate and analyze network elements; it is also a powerful tool to develop new protocol and scheme. In the paper, we analyze the features and models of wireless network in details; discuss the simulation process and implementation of wireless network on the basis of NS2. Also, AODV protocol and self-defined MFlood protocol in wireless network are simulated...
