| 摘 要： | 多协议标签交换（MulfiprotocolLabelSwitching，MPLS）在无连接的IP网络上通过引入面向连接的标签交换概念，将第3层路由技术和第2层交换技术相结合，充分发挥了IP路由的灵活性和两层交换的便捷性，被广泛应用于大型网络中，可承载多种业务，网络可扩展性很强．但一旦承担的某种业务占用带宽过大，整个网络都将出现拥塞，甚至丢包的现象．针对MPLSVPN出现的网络服务质量无法保证的问题，提出了支持DIFF—Serv的MPLSVPN模型解决方案，并通过实验和应用证明了该方案的可操作性和有效性．

| Abstract: | By introducing the concept of connection-oriented label switching in connectionless IP network,MPLS(Multiprotocol Label Switching) combines the third layer routing technology and the second layer switching technology,gives full play to flexibility of IP routing and simplicity of the second layer switching.MPLS has strong network scalability,can be widely applied,and can provide a variety of services.However,once a service takes up too much bandwidth,the entire network will be congested,or even worse,packet will be dropped.To guarantee QoS(Quality of Service) in MPLS VPN network,a solution based on MPLS VPN model which supports Diff-serv(Differentiated Service) is proposed.The operability and effectiveness of the solution are confirmed in experiments and applications. |
