移动IPv6中QoS的实现

现有的网络服务质量(QoS)有两大模型:集成服务(Intserv)和区分服务(D iffserv)。这两种服务都是针对静态环境(固定主机和固定路由)设计的,对于移动通信网络都不能完全适用。本文结合集成服务和区分服务的优点,提出了一种新的双平面的三重QoS体系,并描述了这一体系对端到端QoS的实现。最后通过实例概述了QoS体系的整体流程,扩展了移动IPv6(M IPv6)信令中的绑定升级(BU)、绑定请求(BR)、绑定确认(BA)三个选项。

Implementation of QoS in Mobile IPv6

There are two types of Internet Quality of Service(QoS): Intergrated Services(Intserv) and Differentiated Services(Diffserv).They are designed in the context of a static environments(fixed hosts and fixed networks),so these schemes are not fully adaptable to mobile environments.This paper proposes a new two-plane three-tier QoS architecture based on the advantages of Intserv and Diffserv,and describes how the architecture guarantees the End-to-End QoS.Finally,through an example,it summarizes the whole flow of the QoS architecture and advance resource reservation of the existing Mobile IPv6 signalings such as Binding Update,Binding Request and Binding Acknowledge are extended.
