Embodiment 1

[0063] like figure 1 As shown in , it is a schematic diagram of a vOLT multicast implementation solution provided by the embodiment of the present invention. The implementation of the program is:

[0064] Firstly, different forwarding domains are pre-allocated for each vOLT system in the PON system, and different GEMPORT IDs are allocated for each vOLT system, and the GEMPORT ID is used to bear the downlink multicast flow. And maintain the first table to record the corresponding relationship between each vOLT ID and GEMPORT ID. In this way, the system multicast pre-configuration is completed, and then the configuration of the GEMPORT ID needs to be delivered to the ONU user.

[0065] The control layer software module completes the service configuration of vOLT, and configures each ONU under each PON port into a vOLT system with different service requirements. The optical wavelengths of GPON and XGPON / XGSPON are different, and two different physical channels are used in COMB...

Embodiment 2

[0072] like figure 2 As shown, it is a flowchart of a method for creating a mapping between a vOLT ID and a downlink multicast GEMPORT ID in an embodiment of the present invention, and the steps include:

[0073] Step S101: During the vOLT initialization process, assign a unique GEMPORT ID for each vOLT to bear the downlink multicast flow, and record it in the first table. As shown in the first table, it is a mapping relationship table between vOLT ID and GEMPORT ID. It can be seen that each vOLT ID is in one-to-one correspondence with each GEMPORT ID.

[0074] Mapping relationship between vOLT ID and GEMPORT ID in the first table

[0075] vOLT ID GEMPORT ID 0 A 1 B 2 C n X

Embodiment 3

[0077] like image 3 As shown, it is used to create a flow chart of ONU ID & physical channel and vOLT ID mapping method in the embodiment of the present invention, and the steps include:

[0078] Step S201: when configuring the vOLT attribute of the ONU, record the mapping information of the physical channel of the ONU, the ONU ID binary group and the vOLT ID into a second table, that is, map to the vOLT ID through the combination of the ONU ID and the physical channel.

[0079]The second table is the mapping relationship table between ONU ID & physical channel and vOLT ID, that is, the two-tuple ONU ID and physical channel are mapped to vOLT ID; and then the combination query of the second table and the first table can get the corresponding ONU ID & physical channel GEMPORT ID. As in the example in the second table, two ONUs No. 1 and No. 2 under physical channel 1 and No. 1 ONU under physical channel 2 are configured in vOLT No. 0; ONU No. 3 under physical channel 2 is con...

Abstract

The invention discloses a vOLT multicast method, comprising: assigning each vOLT a different multicast-specific GEMPORT ID for carrying downlink multicast streams, and establishing a binding relationship between the vOLT ID and the multicast-specific GEMPORT ID The first form; each ONU is configured into the vOLT of different service demand levels, and the second form of the binding relationship between the ONU ID, the physical channel and the corresponding vOLT ID is established; in combination with the first form, the multicast dedicated information corresponding to each ONU is obtained. GEMPORT ID, and send it to the corresponding ONU, and configure the attribute of the GEMPORT ID as broadcast; analyze the uplink multicast signaling message of the ONU, and realize the joining or leaving of the ONU multicast. Through the method of the present invention, in the vOLT system, each ONU under the PON port is configured into vOLTs of different service demand levels, and different GEMPORT IDs are assigned to each vOLT to bear the downstream multicast flow, so as to realize different service demand levels. ONU user multicast isolation. The present invention also provides an OLT device for realizing the above method.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and more specifically relates to a vOLT multicast method and OLT equipment. Background technique [0002] PON (Passive Optical Network, Passive Optical Network) system consists of OLT (Optical Line Terminal, Optical Line Terminal) at the central office, ODN (Optical Distribution Network, Optical Distribution Network) and ONU (Optical Network Unit, Optical Network Unit) on the user side . [0003] GPON (Gigabit-capable Passive Optical Networks, passive optical network with gigabit function) system and XGPON / XGSPON (10-Gigabit-capable Passive Optical Networks, passive optical network with ten-gigabit function) system are optical Access network equipment, which can carry Ethernet services, analog telephone services, IPTV (Internet Protocol Television, Internet TV) and other services. With the deployment and planning of high-bandwidth equipment by major operators, PON equipment is incr...
