Dedicated line opening method and device

Abstract

The invention provides a dedicated line opening method and device, relating to the technical field of communication, and aiming at opening a dedicated line more quickly and flexibly. The method is applied to a dedicated line management system, and the system includes at least two access routers, centralized control equipment and a business server, wherein each access router is connected to a corresponding UTN, each UTN is connected to an IP bearer network to form a backbone network, the at least two access routers have established tunnel communication based on the backbone network, and the business server is used to provide business services. The method includes the following steps: enabling the centralized control equipment to receive a dedicated line opening request message sent by the first access router; sending an authentication request message to the business server according to the dedicated line opening request message to ensure that the business server authenticates the firstaccess router; receiving an authentication response message sent by the business server; and if the authentication response message indicates that the authentication of the first access router is successful, enabling the centralized control equipment to send a dedicated line opening response message to the first access router.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a dedicated line method and device. Background technique [0002] With the rapid development of communication technology, end-to-end services can be transmitted quickly and safely by opening an end-to-end leased line. [0003] At present, in the process of opening a dedicated line, a dedicated line (may be referred to as an MSTP dedicated line for short) may be opened based on a multi-service transfer platform (Multi-Service Transfer Platform, MSTP). Such as figure 1 As shown, taking the opening of the MSTP private line between client device 1 and client device 2 as an example, the networking architecture of the MSTP private line is: access network 1, local network 1, backbone network, peer local network 2, peer The access network 2 at the end, the client device 1 connected to the access network 1, and the client device 2 connected to the a...

Problems solved by technology

[0004] However, in the above leased line activation method, because the MSTP leased line is a physical dedicated channel, the resource utilization rate is low, and the MSTP leased line adopts the MSTP technology of time slot exchange, so the network efficiency is low

Especially when opening a leased line, it is necessary to manually configure the access network, local network, and backbone network, resulting in a long time for opening a leased line, and the flexibility of subsequent leased line management (such as bandwidth management, etc.) is poor
