The Adaptive SAR Technology in Non-ATM Network Node

摘要

the IP packet length distribution is changing with the Internet development and traffic. Different network also has different IP packet length distribution.Now, the IP packets processing methods of many non-ATM network nodes are similar with Segment and Reassemble (SAR). The payload length of the cell is fixed. When the network node is placed in a network, a large mount of redundant bytes, which result from the zero-pads and headers being used, decrease the processing bandwidth. And, when a well-designed node is placed in different network with different distribution,the processing bandwidth of the node may be even lower.In this paper, an adaptive IP packets SAR processing solution, which can adapt the traffic of the network, is present. And, the computer simulations based on the packet length statistic data [1] are also given.
