摘要
尽管有许多关于AF- PHB机制和基于AF的服务实现的建议，但是根据DiffServ框架实现成功的保证转发(AF)服务仍然是一个具有挑战性的问题。在这项工作中，我们提出了两个模块，tcp窗口感知标记(TWAM)和动态WRED (DWRED)机制来实现DiffServ AF PHB。我们提供了分析模型和实验评估，以证明它们如何成功地提高了质量，增加了公平性，提高了性能，并简化了生产级基于af的服务的部署。
Performance enhancement of an AF service using TCP-aware marking and dynamic WRED
The implementation of successful assured forwarding (AF) services according to the DiffServ framework remains a challenging problem today, despite the numerous proposals for AF PHB mechanisms and AF-based service implementations. In this work, we propose two modules, the TCP-window aware marker (TWAM) and the dynamic WRED (DWRED) mechanism for implementing the DiffServ AF PHB. We provide analytical models and an experimental evaluation in order to demonstrate how they succeed in enhancing the quality, increasing fairness, improving the performance and easing the deployment of a production- level AF-based service.
