摘　　要：论文针对网络服务的应用,研究了UCLA设计的网络加速器模型,发现UCLA网络加速器设计在某些情况下得到较多不合理的下一跳出口地址,减低了加速器的性能。通过增加运算符改进加速器的运算,减少了所查找的路由表的出口数目,能更准确地定位下一跳的位置,提高了加速器的效率。This paper depicts a modified model for route table lookup according to UCLA designed network accelerator for network service applications.UCLA network accelerator will get more unreasonable next hop addresses under certain circumstances and reduce its performance.By adding new operator and operand for network accelerator,the improved network accelerator reduces the next hop ports of route table desired to look up and can be more accurate to locate next hop address which improves network accelerator performance.
