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 Operations Profile (MOP) can only implement basic viewing permissions Control, unable to control the preview function of multicast, and the business application is greatly restricted

Embodiment 1

[0046] In this embodiment, the existing GPON OMCI standard management interface definition is used, and the OLT is still used to issue the multicast authority control table, and the ONU independently controls the multicast protocol, that is, centralized authority management and distributed protocol control. To manage and control the preview business.

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

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

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] The first step is to create a multicast preview template mpp0 on the OLT, id is 1, set the number of previews to 10, the maximum duration of preview is 300 seconds, and the minimum interval of preview is 60 seconds. And the multicast preview template mpp0 is configured on the ONU through the Multicast preview profile OMCI 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 configure the multicast operation profile mop0 to the ONU through the Multicast operation profile OMCI interface defined by the G984.4 standard.

[0079] The third...

Embodiment 2

[0085] In this embodiment, the existing GPON OMCI standard management interface definition is used, and the OLT is still used to issue the multicast authority control table, and the ONU independently controls the multicast protocol, that is, centralized authority management and distributed protocol control. To manage and control the preview business. The difference from Embodiment 1 is that the OLT directly carries the multicast preview control parameters in the MOP (Multicast Operation Profile) management object, and the ONU controls the multicast preview function when receiving the multicast preview application according to the above setting parameters.

[0086] In order to support the perfect ONU multicast preview function, the OLT needs to configure the channel preview permissions and related preview parameters to the ONU. You can specify the access permissions (viewing or preview) for each multicast channel in the multicast permission control table, and Configure preview par...

Abstract

The invention discloses a multicast service control method and an optical network unit (ONU). The method comprises the following steps: configuring a multicast preview control parameter to the ONU by an optical line terminal (OLT), and when a multicast request is received by the ONU, achieving a multicast preview function according to the multicast preview control parameter. According to the multicast service control method and the ONU, the problems that the preview service cannot be controlled, and the service application type is single in the correlation technique are solved; a standard multicast control method is perfected, thereby, the multicast preview service can be supported, and the service types which can be realized are enriched.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular, to a multicast service control method and an optical network unit (Optical Network Unit, referred to as ONU for short). Background technique [0002] Gigabit Passive Optical Network (Gigabit Passive Optical Network, referred to as GPON) is a kind of point-to-multipoint network structure, passive optical fiber transmission mode, based on GPON encapsulation method (GPON Encapsulation Method, referred to as GEM) frame encapsulation, providing multiple An integrated service broadband access technology. [0003] GPON is composed of three parts: the central office equipment Optical Line Terminal (Optical Line Terminal, referred to as OLT), user equipment ONU, and Optical Distribute Network (Optical Distribute Network, referred to as ODN). With the large-scale application of GPON technology in recent years, how to develop controllable multicast services on GPON has become a topic worth...
