LAN-VPLS STITCHING METHOD, SYSTEM AND COMPUTER READABLE MEDIUM

摘要

According to one embodiment, provider edge routers may be queried and required information for deploying a missing VPLS service on a target router may be obtained. This allows a Local Area Network (LAN) to Virtual Private LAN Service (VPLS) to stitch in an automated manner without an operator of the cloud management system requiring knowledge of the types of VPLS services involved in the stitching process.

1. A method for connecting a Local Area Network (LAN) to a Virtual Private Network (VPN) via a Provider Edge (PE) router using a layer 2 Virtual Private LAN service (VPLS), the VPN being facilitated by an underlying physical network of a Service Provider (SP) and the VPN being managed by a cloud management system, the method comprising:
the cloud management system providing a list of available VPLS services for connecting said LAN to the VPN along with an address of said PE router, each VPLS service having a different VPLS identifier (VPLS_ID); choosing a VPLS service from among the list of VPLS services; the cloud management system determining whether a suitable VPLS service is deployed on the PE router; if it is determined that a suitable VPLS service is deployed, the cloud management system generating a Service Access Point (SAP) within the PE router to connect the LAN to the VPN network; if it is determined that a suitable VPLS service is not deployed, the cloud management system obtaining a list of all the VPLS services that are deployed on other PE routers within said underlying physical network of the SP that are associated with the chosen VPLS service; the cloud management system determining whether a suitable VPLS service is deployed on another PE router based on the obtained list; if it is determined that a suitable VPLS service is on another PE router, the cloud management system obtaining deployment information from said another PE router, the cloud management system further deploying the suitable VPLS service on the PE router using the deployment information and subsequently generating the Service Access Point (SAP) within the PE router to connect the LAN to the VPN network.
