Embodiment Construction

[0029] The purpose of the present invention is to provide a method for implementing multicast authentication and control in a passive optical network system and a passive optical network system using the method, so as to make full use of the bandwidth of the passive optical network system in actual use. The following two The multicast service terminal is taken as an example for illustration. For multiple multicast service terminals, the implementation method is the same. In the whole processing flow, the processing of all multicast protocol packets strictly follows the relevant standards of the multicast protocol.

[0030] image 3 It is a flow chart of the multicast authentication and control method for the passive optical network system provided by the present invention. In this flow, the multicast service terminal 1 carries out the interaction of the multicast service through authorization, but the multicast service terminal 2 fails to pass the authorization. Therefore, the...

Abstract

The invention discloses a passive optical network system with multicast authentication and control functions and an implementing method thereof. In the method, an ONU monitors the interaction between a multicast service terminal and a BRAS to acquire a user name and multicast authority of the multicast service terminal; and a multicast forwarding table is set on the basis; multicast messages are filtered according to the multicast forwarding table; and an OLT bypasses all multicast messages and processes the multicast messages on a master control panel by adopting a multicast protocol, so that the multicast user authentication and control of the passive optical network system are realized.

Description

technical field [0001] The invention relates to a passive optical network system, in particular to a passive optical network system with multicast authentication and control functions and its realization method. Background technique [0002] BRAS (Broadband Remote Access Server, broadband remote access service equipment). [0003] With the rapid development of communication technology, the broadband Internet service has become the most eye-catching service in the telecommunications business. Among many broadband Internet access services, the multicast (Multicast) service is particularly important. Emerging broadband services represented by multicast all require large bandwidth and small forwarding delay, which puts higher and faster demands on the existing telecommunication network. Due to the vigorous development of the backbone transmission network in the early stage, the access network has become the bottleneck of the entire telecommunication network. Existing access t...
