摘要
就MPLS的产生背景、MPLS标签、MPLS流量工程、MPLSVPN应用等展开叙述。MPLS的问世可以保证如语音传送、视频服务、多媒体信息传输等新应用业务按各应用的特性正确予以传送。MPLS网络中数据的传输靠标签引导。标签是固定长度的、无结构的值。采用MPLS流量工程可以避免引起网络阻塞 ,为用户提供更好的服务。在CiscoIOS网络中 ,MPLS虚拟专用网提供了发展和管理第 3层VPN骨干服务的能力。
This overview describes the background of MPLS,MPLS label,MPLS Traffic Engineering and MPLS VPN applications,et al.The coming out of MPLS may assure the proper transmission of some new services according to their characters of application,such as phoneme transmission,video service,multimedia information transmission.The data transmission in MPLS network is led by label.The label is an unstructured value with fixed length.The network choking can be avoided by using MPLS Traffic Engineering and better service for user provided.The use of MPLS Virtual Private Network(VPN)in Cisco IOS networks provides the capability to deploy and administer the scalable layer 3 VPN backbone services.The development of MPLS technology makes IP service capable of supporting QoS.
