Evaluation of the Redundant Traffic Reduction Node Using the Packet Cache Coping with Different Byte Offsets among Streams

In recent computer networks, amount of redundant traffic by services including video delivery is increasing. Our research group improved performance of network node that reduces the redundant traffic with the packet cache. When differences of byte offsets among redundant streams increase, the node requires large cache. We implemented the new function in the node that restrains replacement of the data in the cache when the differences are large. We successfully decreased frequency of removing data that would be referred soon. Therefore, the node reduced the traffic efficiently with smaller size cache.
