Method and device for activating private line service

Abstract

The embodiment of the present invention discloses a private line service opening method and device, and relates to the field of communication. The problems are solved that time and power are consumedand the optical fiber bandwidth resources are wasted. The method comprises the steps of: obtaining a first access layer device and a second access layer device at two ends, and the types of private line service to be opened at the two ends, determining a first core layer device and a second core layer device, determining corresponding path quality according to the routing hop count, the bandwidthusage efficiency and the cost value of each path between the first core layer device and the second core layer device, determining the failure rate of each path, determining a target path according tothe path quality and the failure rate of the path and the types of the private line service, and sending routing information to the first core layer device, the second core layer device and devices which the target path passes through. According to the embodiment of the invention, the private line service opening method and device are used in the process of opening the trans-provincial private line service.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a method and device for activating a dedicated line service. Background technique [0002] With the increasing demand of users for intelligent and automated network services, the development of private line services is facing a bottleneck. In the prior art, when operators provide users with cross-provincial virtual private network (Virtual Private Network, VPN) dedicated line services, they can use optical fiber direct connection, that is, connect optical fiber between the capital cities of two provinces, To open the private line business. [0003] However, with the introduction of software-defined network (Software Defined Network, SDN) technology, the opening of private line services has become convenient and fast, which has increased the business volume of inter-provincial private lines. At this time, if the leased line service is still activated thro...
