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。
Taking full advantage of the potential of IPv6 to support QoS, a multi-constrained QoS routing algorithm based on diffusion was designed. In the algorithm, the flow label field in the basic header of IPv6 packet is used to uniquely identify the service flow and accelerate the packet classification of the data flow. The hop-by-hop extension header in the extension header records the service flow requirement and completes the access control, And real-time feedback is provided to solve the problem that it is difficult for an IPv4 diffusion algorithm to support multiple measurement parameters at the same time, which is difficult to timely feedback and improve the forwarding efficiency of real-time streaming data packets.
