| 2 | Performance Comparison and Analysis of IP and MPLS Networks显示文摘With the increasing need for Quality of Service( QoS ),the traditional IP network is becoming less competitive. In order to give readers quantitative and convictive performance comparisons between IP and MPLS network,we choose Berkeleys NS 2 simulator [1] in our research on network throughput and end to end TCP behavior. Using NS 2 simulator,we analyze the performance of a network with MPLS Traffic Engineering( MPLS TE ).Specifically,the throughput and TCP end to end delay time under two different queuing algorithms are obtained and compared between the MPLS network and traditional IP network. We find that in the IP network using SFQ queuing algorithm will help traffic balance compared to the simple FIFO scheme,but it still can not utilize the available bandwidth,which in turn leads to the poor performance as in the FIFO case.With MPLS TE , the throughput will be higher and the end to end TCP delay time remains almost the same even in heavy load case.We notice that if flows are isolated partially,using SFQ scheme will have a comparable performance as the fully isolation case using FIFO scheme in a MPLS network,and that if flows are isolated fully for FIFO and SFQ schemes,both will have the same result.Finally,we conclude that a better queuing algorithm will help reduce the label space requirement. | LIU Er wu, CAO Ming cui, CHEN Chun han, LI Feng (State Key Laboratory of Laser Technology, Huazhong University of Science and Technology, Wuhan 430074, P.R.China) | 2001 | The Journal of China Universities of Posts and Telecommunications2001，8，2： | 3 |
