园区网中QoS解决方案的研究

随着网络技术的发展,网络用户的增多以及各种大型实时的多媒体应用在园区网上实施,园区网在大学、公司和医院等企事业单位的生产和发展过程中发挥着越来越重要的作用,同时网络应用对网络服务的QoS提出更高的要求。本文介绍在园区网实施QoS方案的主要策略;分析DiffServ模型,DiffServ通过对园区网中的通信数据包进行分类和策略控制来达到调节网络资源的目的;探讨区分服务模型的实现,从而实现园区网的QoS保证。

Study on QoS Solution for Campus Networks

With the development of network technology, the increasing number of network users and the implementation of all kinds of large-scale real-time multimedia applications in network, campus network plays an increasingly significant role in the pro- duction and development process of enterprises and institutions, snch as universities, hospitals and companies. Meanwhile, the network applications request for higher quality of network service. This paper introduces the main strate~es of QoS solution for campus network, analyzes the DiffServ model, which adjusts the network resources by classifying and policy-control of correspon- dence data packets for campus networks, and investigates the realization of DiffServ model, so that it guarantees the QoS for cam- pus networks.
