随着业务量的爆炸式增长和不断扩大的服务质量（QoS）的要求，从新兴的多媒体应用，已经进行了广泛的研究，以解决各种问题的QoS路由相对于互联网。流量被分为具有不同优先级的几个服务类别;具有高优先级的流量所使用的路由算法不仅对它自己的流量类别有显著影响，而且对所有其他流量类别也有显著影响。我们的目标是开发多类QoS路由提供优良的尽力而为的流量性能，而不会对QoS流量的性能产生不利影响。为此，我们将在本文中介绍一种新的方法来QoS路由的基础上的“虚拟剩余带宽”的概念与网络的状态，并评估我们的计划使用详细的模拟的有效性。我们的研究结果表明，该算法是成功的，在提高最大努力流量的性能，同时保持QoS流量的性能，如果QoS流量是网络上唯一的流量。
With the exploding volume of traffic and expanding Quality of Service (QoS) requirements from emerging multimedia applications, extensive research has been carried out to address various issues in QoS routing with respect to the Internet. Traffic is classified into several service classes with different priorities; the routing algorithm used by traffic with a high priority has a significant effect on not only its own class of traffic, but also on all other classes of traffic. Our goal is to develop multi-class QoS routing providing excellent Best Effort traffic performance without adversely affecting the performance of QoS traffic. For this end, we will introduce in this paper a new approach to QoS routing based on the concept of ‘Virtual Residual Bandwidth’ associated with the state of network, and evaluate the effectiveness of our scheme using detailed simulations. Our findings show that the proposed algorithm is successful in improving Best Effort traffic performance, while maintaining the performance of QoS traffic as if QoS traffic were the only traffic on the network.
