In this paper , we will review the features , main components of mpls and its qos mechanism ( such as interserv , diffserv , te ) . and then we will describe the design and the implementation of mpls network simulator , which supports the establishment of lsp as well as any other basic mpls functions such as ldp and label switching and various approaches which can be used to support differentiated services in mpls environment and implement diffserv + mpls in ns 本文中,我们对mpls的基本协议,体系结构以及它的qos机制做了回顾。然后,设计并实现了一个基于ns的mpls模拟环境,它支持基本的mpls功能(如ldp ,标记交换, lsp的建立等) 。接着,我们在基本mpls协议的基础上,实现了基于di邢ery的qos保证。
Abstract : this article briefly analyses the interrelationship between ip and atm , which are core network technologies , and describers multi - protocol label switching ( mpls ) , a new generation network technology that converges ip and atm , and its role in the process of convergence of the internet and the telecom network 摘要:简要分析了作为网核心技术的ip与atm间相互关系,阐述了作为两者融合的新一代网络技术即多协议标记交换( mpls ) ,以及其在因特网与电信网融合演进过程中的作用。
( 4 ) study of the qos architectures suggested by ietf : intserv / revp , diffserv and mpls . discuss the protocols , point out strengthen the congestion control mechanisms to support the qos system . finally , we make the conclusions and some future researches are proposed 4 )分析了由ietf建议的qos保证方案主要由:综合服务( intserv ) rsvp 、浙江大学硕士学位论文区分服务( diffsery ) 、多协议标记交换( mpls ) ,对三种方案进行分析,通过增强拥塞控制保证网络服务质量( qos ) 。
