Problems solved by technology

[0006] The multicast permission control table defined by the G984.4 standard, that is, the Dynamic access control list table (dynamic access control list) defined in the multicast operation profile (Multicast Operations Profile, referred to as MOP), can only realize basic viewing permission control, and cannot control the multicast The preview function is controlled, and the business application is greatly restricted

Embodiment 1

[0046] In this embodiment, the existing GPONOMCI standard management interface definition is used, and the OLT is still used to issue the multicast authority control table, and the ONU independently performs multicast protocol control, that is, centralized authority management and distributed protocol control. Manage and control the preview service.

[0047] In order to support the complete ONU multicast preview function, the OLT needs to configure the channel preview rights and related preview parameters on the ONU. You can specify the access rights (watch or preview) for each multicast channel in the multicast rights control table, and Configure the preview parameters related to the preview permission, including the number of previews, the maximum duration of the preview, the minimum interval of the preview, etc., and the ONU performs preview control according to the issued multicast permission control table.

[0048] The specific preview parameter configuration method is as...

example 1

[0076] Set the multicast VLAN to 100, the multicast IP address to 224.1.1.1, and the permission to preview. The specific configuration and control process includes the following steps:

[0077] Step 1: Create a multicast preview template mpp0 on the OLT, set the id to 1, set the number of previews to 10, the maximum preview duration to 300 seconds, and the minimum preview interval to 60 seconds. And the multicast preview profile mpp0 is configured on the ONU through the MulticastpreviewprofileOMCI interface defined in this embodiment.

[0078] The second step is to create a multicast operation template mop0 on the OLT, add 224.1.1.1 to the dynamic access control list, and set the Reserve field to 1 (this process realizes the establishment of an association between the channel and the preview template). And the multicast operation template mop0 is configured on the ONU through the MulticastoperationprofileOMCI interface defined by the G984.4 standard.

[0079] The third step ...

Embodiment 2

[0085] In this embodiment, the existing GPONOMCI standard management interface definition is used, and the OLT is still used to issue the multicast authority control table, and the ONU independently performs multicast protocol control, that is, centralized authority management and distributed protocol control. Manage and control the preview service. The difference from Embodiment 1 is that the OLT directly carries the multicast preview control parameter in the MOP (MulticastOperationProfile) management object, and the ONU controls the multicast preview function when receiving the multicast preview application according to the above-mentioned setting parameters.

[0086] In order to support the complete ONU multicast preview function, the OLT needs to configure the channel preview rights and related preview parameters on the ONU. You can specify the access rights (watch or preview) for each multicast channel in the multicast rights control table, and Configure preview parameter...

Abstract

The invention discloses a multicast service control method and an optical network unit. The method comprises: an OLT configures multicast preview control parameters to an ONU; when the ONU receives a multicast request, realizes a multicast preview function according to the multicast preview control parameters . The invention solves the problem that the preview service cannot be controlled and the service application type is single in the related technology, improves the standard multicast control method, can support the multicast preview service, and enriches the service types that can be realized.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multicast service control method and an optical network unit (Optical Network Unit, ONU for short). Background technique [0002] Ethernet Passive Optical Network (Gigabit Passive Optical Network, referred to as GPON) is a point-to-multipoint network structure, passive optical fiber transmission mode, based on GPON encapsulation method (GPONE Encapsulation Method, referred to as GEM) frame encapsulation, providing a variety of integrated services broadband access technology. [0003] GPON is composed of three parts: optical line terminal (Optical Line Terminal, OLT for short), user end equipment ONU, and optical distribution network (Optical Distribute Network, ODN for short). With the large-scale application of GPON technology in recent years, how to develop controllable multicast services on GPON has become a subject worth studying. [0004] A GEM encapsulation port (Gempo...
