The Key Technology Of MPLS And Its Application In Metropolitan Area Network Of Liaoning Mobile

With the increasing popularity of the Internet, the main Internet business from the traditional FTP,E-mail and rlogin and other multimedia applications to the WWW . Information in the network continued to increase, resulting from the traditional multi-network router constitute trend saturation. The rapid development of multimedia communications (such as telephone networks, e-commerce, video conferencing, etc.)QoS networks can provide different levels of integrated services (such as delay, bandwidth and packet loss rate guarantees).Because no link to the Internet-oriented IP (Internet Protocol).only can do best-effort), it is unable to provide QoS. When the existing Internet expanded to a certain size limit, it will in many respects (bandwidth, routing, network scalability, QoS) challenges. MPLS network as the core technology has been applied to a large number of network operators in the provinces and cities nationwide backbone network and the MAN, some of the major park network, or enterprise network will also set up MPLS VPN network for the application.This thesis studies the key MPLS technology, Liaoning Mobile Network, integrating theory with practice, of the key technologies in Liaoning Mobile MPLS MAN of analysis and research. Finally, a brief study on the prospects of MPLS.
