摘要

本文探讨了差异化服务所支持的两类服务的性能——保证服务和溢价服务。它着重于用于实现加速转发每跳行为(EF PHB)和保证转发PHB (AF PHB)的机制，并根据主要QoS参数:吞吐量、延迟和丢包率对它们进行分析。研究了调度算法的影响，以及AF(保证转发)和EF(加速转发)对BE (Best Effort)流量的影响。在不同的流量条件(不同的突发程度、数据包大小和流量服务类型)和不同的参数下进行了模拟。

Performance analysis and comparison of assured and premium service in differentiated services networks

This paper explores the performance of the two types of services supported by the Differentiated services - Assured Service and Premium service. It focuses on the mechanisms used for implementation of the Expedited Forwarding Per-Hop Behavior (EF PHB) and Assured Forwarding PHB (AF PHB), analyzing them with respect to the main QoS parameters: throughput, delay and drop rate. The impact of the scheduling algorithms and also the impact Of AF (Assured Forwarding) and EF (Expedited Forwarding) on the BE (Best Effort) traffic is investigated. Simulations were carried out under different traffic conditions (different levels of burstiness, packet sizes and traffic service types) and different parameters.
