MPLS网络服务质量控制的策略与机制

QoS control policies and mechanisms on MPLS network

为充分发挥网络资源的效能,提高服务质量,就必须对实现网络服务质量(QoS)保证的机制进行深入研究.目前采用MPLS技术实现QoS的解决方案已经成为这一领域的研究趋势.基于MPLS技术的基本原理,从体系结构、流量工程、环路控制、故障恢复与防止等关键技术出发,对实现QoS的方案展开研究,在实际应用中,通过有限的软硬件升级,实现端到端的QoS保证.

To use network resource effectively and improve （QoS） quality of services , it is necessary to make a deeper research on the guarantee system of the network QoS . It is a trend now to use MPLS technology to realize the QoS . This paper gives the QoS realization methods with some key technologies such as the architecture , traffic engineering ,loop control ,failure recovery and precaution and so on, based on the principle of MPLS（ multi-protocol label switching） technology. The end-to-end QoS guarantee is realized in real application through limited upgrading of software and hardware.
