Problems solved by technology

In the current GPON standard, the multicast filter table of each ONU can be configured through the OMCI (ONT Management And Control Interface) channel, but there is no definition of the relevant management method for the MVR function on the ONU side
Therefore, when using the existing multicast mode, the management of each multicast user under the same ONU cannot be realized
At the same time, since the ONU is located on the user side, if the user multicast authority management is placed on the ONU, the security cannot be effectively guaranteed
[0009] It can be seen that in the current GPON standard, safe and efficient MVR multicast cannot be realized

Embodiment Construction

[0041] The method described in the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] In the present invention, the IGMP and MVR protocols are run on the OLT side, and the multicast users are managed and controlled according to the configuration of the network management. The main idea is that the OLT configures the legal multicast user information on the ONU through the OMCI channel; sends the multicast data stream to the ONU through the broadcast GEM Port; and configures the legal multicast user information on the ONU through the OMCI channel; According to the user multicast configuration information, the ONU copies the downlink multicast data flow, performs VLAN conversion, and sends it to each multicast user.

[0043] Specifically, for the implementation method of MVR in the GPON system of the present invention, refer to figure 2 The multicast schematic diagram shown mainly includes...

Abstract

The invention discloses a realizing method for an MVR (multicasting virtual LAN registration) in a GPON (Gigabit-capable Passive Optical Network) system. An IGMP (internet group management protocol) and an MVR protocol are operated at an OLT (optical line terminal) side to manage multicasting information and user multicasting authority; simultaneously, the OLT collocates legal multicasting user information on an ONU (optical network unit) through an OMCI (optical network terminal management control interface). The OLT sends a multicasting data flow to the ONU through broadcasting GEMPort (GPON sealing mode port mark). The ONU carries out filtering, copying and VLAN switch on the downgoing multicasting data according to the multicasting information collocated by the OLT and sends thereof to each multicasting user. The method of the invention improves the integration and security of management, simplifies the design of ONU and simultaneously improves the operating factor of bandwidth.

Description

technical field [0001] The present invention relates to the multicasting technology in the GPON (Gigabit Passive Optical Network) system, in particular to a method for realizing MVR (Multicast Virtual Local Area Network Registration, Multicast VLANRegistration) in the GPON system. Background technique [0002] Passive Optical Network (PON) technology is a point-to-multipoint optical fiber access technology, which consists of OLT (Optical Line Terminal) on the office side, ONU (Optical Network Unit) on the user side and ODN ( optical distribution network). Generally, the downlink adopts TDM (time division multiplexing) broadcast mode, and the uplink adopts TDMA (time division multiple access) mode, and can flexibly form tree, star, bus and other topological structures (the typical structure is tree structure). [0003] In the GPON system, each data stream is marked with a GEM Port-Id (GPON Encapsulation Mode Port-Id). Two GEMPorts are defined in the standard: unicast GEM Po...
