The Application of MPLS VPN in Improving the Reliability of Test Network

At present, the data transmission of the test network is interrupted due to the breaking of optical cable or the failure of transmission equipment. In order to ensure the reliable transmission of the test network data network and avoid the problem of data transmission interruption in the implementation of the task, redundant lines and equipment need to be added. In this paper, without adding the current test network equipment and links, make full use of the existing equipment idle interfaces and links, using MPLS VPN technology, virtual backup router, in order to achieve the hot backup of the main equipment. Thus, the data of the test network can be transmitted more reliably and the network failure recovery time can be shortened. Due to the support of multi-protocol, MPLS carries a very rich type of business, which enables it to bring new applications in new fields, such as it is used to solve the problem of intranet interworking between companies and enterprises.
