AHPS:公平的混合包调度策略

在综合服务模型中非实时通信虽然不要求严格的服务质量保证,但是它承担着绝大多数网络应用,因而传输性能的影响更广泛。目前用于保证实时连接的服务质量的速率比例包调度算法不能公平地处理非实时通信和实时连接,允许实时连接的通信量任意地抢占未预约带宽,使得非实时通信的传输性能恶化。自适应混合包调度算法不仅保证实时连接的服务质量,而且通过限制实时连接的非协议通信量对网络资源的占用,优化了非实时通信的传输性能,提高了带宽资源的效率。

AHPS:A Fair Hybrid Packet Scheduling Policy

Non-realtime traffic that don't require guranteed QoS in InterServ model undertakes most network applica-tions,so it's performance directly impact applications.Rate-proportional real-time packet scheduling algorithms provide upper bound on delay and provide firewall between sessions,but they don't fairly deal with real-time traffic and non-realtime traffic that don't subscribe network resource.Adaptive hybrid packet scheduling algorithm restricts service for non-contract traffic of real-time sessions and optimizes the performance of non-realtime traffic.
