IPv6单播QoS路由实现的障碍和潜能

Obstacles and Potential of IPv6 Unicast QoS Route Implementation

基于IPv6及其主流的OSPFv3路由协议,分析IPv6实现单播QoS路由可能遇到的障碍,如现有IPv4QoS路由机制的实用性缺陷、多QoS度量表达困难和洪泛更新开销大。利用IPv6的简化报头、流概念、流量类型和流标签域支持QoS路由的潜能。

Based on IPv6 and its main OSPFv3 route protocol, this paper analyses the obstacles met possibly by IPv6 unicast QoS route, such as the current IPv4 QoS routing schemes are not appliable, the multiple QoS metrics are difficult to be expressed and their updates cost much to be flooded and so on. It develops the potential for IPv6 of how to use its simplified packet header, flow concept, traffic class and flow label fields to support QoS route.
