Ipv6中利用汇聚数据流实现QoS的新机制

The Convergence Data Flow Implementation Mechanism of IntServ in Ipv6

本文通过对IntServ模型、DiffServ模型和MPLS模型分析,汲取了它们思想精髓,将同一子网发向同一目的子网的所有数据流聚集成类,以类为单位进行资源申请,在满足QoS要求的链路上建立虚电路,直到该类中所有的Ipv6分组都发送完后,取消虚电路。这种方法既保证数据的QoS要求,也减少了资源申请的次数;降低网络成本,适合在大型网络中应用。

This article has analyzed the IntServ model, DiffServ model and MPLS model, and it absorbs their essence. All data flows from the same subnet to the same destination subnet will be gathered into a class. The class is acted as the unit of resource application, and the virtual circuit is established in the link meeting the QoS requirements;the virtual circuit is canceled until all the Ipv6 packets have been sent. This method not only guarantees the QoS requirements of data, but also reduces the number of the application resources;it has reduced the network cost suiting for the application in large-scale networks.
