Degree-based Strategy for Network Coding in Content Distribution Network
Jiali You · Jisuanji gongcheng · 2009
In a Content Distribution Network(CDN) based on overlay networks with network coding technology, a strategy which is to select the right neighbors to transfer block based upon the degrees of them is proposed. The selection probability of each neighbor is determined by its degree. After this strategy is applied, the utilization of network is improved, and the distribution progress is shortened. Simulation experimental results show that the performance of content distribution is obviously better than the baseline system.
