Problems solved by technology

And as stated in WT-178, access nodes supporting MPLS must support many control / management protocols related to MPLS, for example, support the MPLS architecture according to RFC3031, and support the Label Distribution Protocol (Label Distribution Protocol, LDP for short) of RFC5036 etc., which makes the implementation of the control plane of the MPLS network relatively complicated

Embodiment approach

[0031] In step 206, the AAA server 112 returns an access response to the BNG 110, indicating that user 1's access request is accepted. According to one embodiment of the present invention, the access response includes the LSP information of the virtual access node from user 1 to the VNO 114, and the LSP information includes the information of the access node and the intermediate node on the LSP, and the information of the virtual access node on the LSP. The label corresponding to each physical link and the bandwidth information corresponding to the LSP.

[0032] After receiving the access response, more specifically, after receiving the LSP information, the ANCP server in the BNG 110 generates an ANCP-based access node label configuration message for the access node AN 102 on the LSP (step S208).

Abstract

The present invention provides a method and device for configuring labels based on ANCP in an access network. The method includes: obtaining LSP information of services from users of the access network to the access network, the LSP information includes information of access nodes and intermediate nodes on the LSP, and corresponds to each physical link on the LSP label and the bandwidth information corresponding to the LSP; generate an ANCP-based access node label configuration message for the access node on the LSP, and the access node label configuration message is used to configure the access node to establish a specified access line, a mapping between the uplink port of the access node and the label used on the uplink port of the access node, and is used to indicate the bandwidth occupied by the LSP on the uplink port of the access node; and The access node label configuration message is sent to the access node to instruct the access node to configure the access node according to the access node label configuration message.

Description

technical field [0001] The present invention generally relates to the field of broadband access network communication, and more specifically, relates to a method and device for configuring labels in an access network based on an Access Network Control Protocol (ANCP for short). Background technique [0002] The future access network has a multi-service architecture which introduces Multi-Protocol Label Switching (MPLS) into the access network (eg Broadband Forum BBF (http: / / www.broadband-forum.org) documents TR-144, TR- 145 and WT-178). In a conventional MPLS network, data transmission occurs on a label switching path (Label Switching Path, referred to as LSP), and LSP information includes information about all nodes on the LSP from the source end to the destination end and information related to each physical link on the LSP. The corresponding label makes the implementation of the data plane of the MPLS network relatively simple by using the label on the LSP. And as state...
