一种主动网络环境下的主动队列管理机制

针对主动网络这种新型网络体系能为主动队列的管理提供更加灵活和有效的方法,以及目前主动网络中主动队列的管理仍然简单移用传统网络算法这一情况,深入研究了这种简单移用存在的弊端,及应专门为主动网络设计主动队列管理机制的重要性和必要性。在此基础上,利用主动网络中路由器有着对流经其上的用户数据进行计算的特征,提出了主动网络环境下,基于资源动态协商的主动队列管理机制,并用OPNET8.0进行了仿真实验,验证了该机制在丢包率、队列长度和包延时等方面的优势。

Active queue management mechanism of active network

Active network represents a new approach of network architecture which can provide a more flexible and effective management mechanism for active queue. In view of this and considering that traditional algorithms of active queue management are still used in active network, the shortcoming of using traditional algorithms in active network, importance and necessity of setting up a special active queue management algorithm for active network are studied. Active network's routers can perform computations on user data, while packets can carry programs to be executed in routers and possibly change their state. With this characteristic, an active queue management mechanism, based on dynamic resource trading, is put forward A simulation that used to trove the advantages of the proposed mechanism in packet drop rate, length of queue and packet delay time is made under OPNET8.0 environment.
