Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] Fig. 1 is a network structure diagram according to an embodiment of the present invention, as shown in the figure, the network consists of user terminals (voice terminal 102, data terminal 104 and video terminal 106), home gateway 108, access node 110, and broadband network gateway (BNG (IPTV) 120, BNG (BRAS) 140, BNG (VoIP) 160). Among them, various user terminals are connected to the access node 110 through the home gateway 108 , and the access node 110 is connected to multiple broadband network gateways through the links 10 , 20 and 30 . In this embodiment, access node 110 adopts DSLAM, broadband network gateway BNG (IPTV) 120 can provide IPTV service, broadband network gateway BNG (BRAS) 140 can provide broadband access server service, broadband network gateway BNG (VoIP) 160 IP telephony services can be provided.

Abstract

The disclosed lookup method for broadband network gateway comprises: b. access point sends request for looking up the gateway; and c. the gateway returns the gateway distribution message. This invention ensures finding out gateway in time, and improves business flexibility.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a discovery method of a broadband network gateway. Background technique [0002] The architecture of the current broadband access network includes the following parts: a user network with a home gateway as the core, an access node (Access Node, AN), an aggregation network, and a broadband network gateway (Broadband Network Gateway, BNG). Among them, the home gateway can also be called CPE equipment (Customer Premises Equipment, user end equipment); the access node completes the multi-form access of users, such as DSLAM (DSL Access Multiplex, DSL access multiplexer), etc.; the convergence network completes The function of data aggregation and exchange; broadband network gateway refers to the IP (Interniet Protocol Internet Protocol) edge router that can apply bandwidth and QoS (Quality of Service, quality of service) strategy, such as BRAS (Broadband Remote Access Se...
