For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.

[0030] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Based on multicast services under FTTR networking, multicast clients are connected to optical modems through wireless connection, and there are two use scenarios, and the present application gives a fast switching method for each use scenario as follows.

[0032] Scenario one, multicast data stream will not flood to each optical modem port, and the method is as follows:

[0033] In the normal operation of FTTR networking, each optical cat device actively collects the information of the client hung below and reports to the management end, mainly including MAC, online information, offline information. The "main optical cat" collects these information and records in the local. The multicast client connects the optical cat A through wireless connection. The multicast client switches from "optical cat A" to "optical cat B" in the process of watching multicast. When the multicast client leaves "optical cat A", the "main optical cat" receives the message and retains the locally created multicast forwarding rule while creating multicast forwarding rules to each optical cat device. After the multicast client connects to "optical cat B", it can immediately receive multicast data. After the "main optical cat" receives the message that the multicast client connects to "optical cat B", it will delete the multicast forwarding rules to other optical cat devices.

[0034] Based on the above method of fast switching multicast in FTTR networking, the following steps are mainly included:

[0035] (1) FTTR networking works normally, and the multicast client connects "optical cat A" to watch multicast;

[0036] (2) Optical cat A / B actively collects the MAC, offline information, online information of the client and notifies the main optical cat, and the main optical cat records these information in the local;

[0037] (3) The multicast client leaves the optical cat A, and the main optical cat receives the message that the multicast client leaves the optical cat A, and creates multicast forwarding rules to each optical cat;

[0038] (4) After the main optical cat receives the message that the multicast client connects to the optical cat B, it deletes the multicast forwarding rules to other optical cat devices;

[0039] (5) After the multicast client connects to the optical cat B successfully, it can receive data stream, avoiding the time-consuming of joining again.

[0040] Scenario two, multicast data stream will flood to the slave optical cat port, and the method is as follows:

[0041] In the normal working of FTTR networking, each optical modem device actively collects the information of the client connected below and reports to the management end, mainly including MAC, online information, offline information. The "main optical modem" collects these information and records in the local. After the multicast client connects the optical modem A through wireless connection, the multicast data stream is flooded to each optical modem port by the main optical modem. When the multicast client switches from "optical modem A" to "optical modem B" in the process of watching multicast, the "main optical modem" receives the message and retains the locally created multicast forwarding rule while notifying other optical modem devices to default forward this multicast data stream. When the multicast client connects "optical modem B", the multicast data can be received immediately. After the "main optical modem" receives the message of the multicast client connecting "optical modem B", it will notify other optical modem devices not to forward this multicast data stream.

[0042] Based on the above method of fast switching multicast under FTTR networking, the following steps are mainly included:

[0043] (1) FTTR networking works normally, and the multicast client is connected to watch multicast from optical modem A;

[0044] (2) The optical modem A / B actively collects the MAC, offline information, online information of the client and notifies the main optical modem, and the main optical modem records these information in the local;

[0045] (3) The multicast client leaves optical modem A, and the main optical modem receives the message of the multicast client leaving optical modem A and notifies other optical modem devices to default forward this multicast data stream;

[0046] (4) After the main optical modem receives the message of the multicast client connecting to optical modem B, it notifies other optical modem devices not to forward this multicast data stream;

[0047] (5) After the multicast client is successfully connected from optical modem B, the data stream can be received, avoiding the time-consuming of joining again.

[0048] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
