Embodiment

[0062] In this embodiment, see figure 1 , A method for implementing multicast based on IGMP version 3 of a PON access system, the PON access system includes a main control panel and four line cards, the main control panel includes a CPU and a switching chip, Each line card includes a CPU, a switching chip, and 8 PON ports. The implementation method includes the following steps for the main control panel and each line card:

[0063] Step 100: Set the working version of the PON access system to the third version of IGMP and switch the switching chip of the main control board and the switching chips of all the line cards to the third multicast state.

[0064] Step 101: For each PON port of the line card: the line card receives a multicast member report sent by the user terminal through the PON port, and the CPU of the line card generates a first multicast member information table according to the multicast member report.

[0065] The first multicast member information table includes a p...

Abstract

The invention discloses a PON (Passive Optical Network) access system and an implementation method of multicast thereof. The implementation method comprises the following steps that S1, a CPU (Central Processing Unit) of a line card generates a first triad through a first multicast membership information sheet; S2, a switch chip of the line card receives and stores the first triad transmitted by the CPU of the line card; S3, a CPU of a main control unit generates a second triad through a second multicast membership information sheet; S5, a switch chip of the main control unit receives and stores the second triad transmitted by the CPU of the main control unit; S5, the switch chip of the main control unit transmits multicast data to the line card through an appointed main control unit port in the second triad; and S6, the switch chip of the line card transmits the multicast data to a user terminal through an appointed PON port in the first triad. According to the PON access system, multicast based on the third edition of IGMP (Internet Group Management Protocol) is implemented, and the multicast communication can be more accurately and more efficiently achieved.

Description

Technical field [0001] The invention relates to a PON (Passive Optical Network: Passive Optical Network) access system and a method for implementing multicast based on the third edition of IGMP (Internet Group Management Protocol: Internet Group Management Protocol). Background technique [0002] IP (Internet Protocol: protocol for interconnection between networks) multicast technology uses TCP / IP (Transmission Control Protocol / Internet Protocol: Transmission Control Protocol / Internet Protocol) protocol to realize point-to-multipoint efficient data transmission in IP networks Communication. IP multicast technology has the advantages of high data transmission efficiency, high network bandwidth utilization, low possibility of network congestion, and the ability to avoid broadcast storms that may occur in broadcast and unicast. IP multicast technology is widely used in multimedia conferences, Real-time data transmission, games and many other aspects. The basic method is: when a ce...
