摘要
Diffserv是当前Internet研究领域的一个热点,它不仅具有良好的可扩展性和抗毁性,在服务质量保证方面优于Intserv和MPLS,还可支持多播服务,存在着无限的发展潜力。本文描述了Diffserv体系结构以及它与几种服务质量保证机制的比较,指出了目前Diffserv研究的一些热点问题。
Diffserv has become a hot arena in the Internet research field. It features sound scalability and robustness, superior to Intserv and MPLS in QoS assurance, and supports multicast service with huge development po-tential. In this paper, the Diffserv system architecture and its comparison with some other QoS assurance mechanisms are presented and some hot is-sues concerning Diffserv research are pointed out.
