Proxy placement in coordinated en-route transcoding caching for tree networks
Keqiu Li, Hong Shen · 2004
This paper addresses the problem of transcoding proxy placement for coordinated en-route Web caching for tree networks. We propose a model for this problem by considering all the nodes among the network in a coordinated way and formulate this problem as an optimization problem. We implement our dynamic programming-based algorithm and evaluate our model on different performance metrics through extensive simulation experiments. The implementation results show that our model outperforms the placement model for linear topology.
