区域标记交换网QoS保证措施及性能仿真分析

网络服务质量是目前网络研究的热点问题,已经成为下一代网络最重要的研究内容.区域标记交换网继承了IP网络的无连接特性,采用区分服务的方式提供服务质量保证,在此基础上,提出了一种基于资源的全局接纳控制思想,能够更加合理的管理网络资源,同时实现服务质量保证和网络资源的有效利用.最后,通过OPNET建立的网络仿真模型,验证了区域标记交换体制下QoS保证机制对网络性能的影响.

Switching Network and An Analysis of its Performance

To guarantee QoS of networks has become a research focuses. The Regional Code Label Switching Network inherits the connectionless character of IP network, using DS mechanism to ensure QoS. A global admission control thought based on network resources is proposed, which can manage and distribute network resources reasonably, implement QoS and make efficient use of network resources. Finally, a network-emulating model based on OPNET is set up. Results show that better performance can be achieved in RCLS network.
