摘要
充分利用IPv6支持QoS的潜能,设计了一种基于扩散的多约束QoS路由算法。算法中利用IPv6数据包基本报头中的流标签字段唯一标识业务流并加速数据流的包分类,利用扩展报头中的逐跳扩展头记录业务流需求并完成接入控制,利用路由头记录扩散包的转发路径并实现及时反馈,解决了IPv4扩散算法很难同时支持多度量参数、很难及时反馈等问题,提高了实时流数据包的转发效率。
This paper proposes a multi-constrained flooding-based QoS routing in IPv6. Flow label in IPv6 basic header is used to identify traffic flow exclusively and accelerate packet classification. Hop-by-hop header in IPv6 extension header is used to record QoS requirements of applications and accomplish admission control. Routing header is used to trace path and feed back timely. From this way it addresses the problems such as the difficulty of supporting multiple metrics at the same time and feeding back timely in IPv4 QoS routing algorithms. And it also improves packets forwarding efficiently.
