Abstract

The invention discloses a device for realizing multicast of an EPON access system and a method thereof. The device comprises an OLT, an ODN and an ONU, wherein a module for operating IGMP Proxy Layer 2 Multicast Protocol is arranged on a main control panel of the OLT; the multicast address list item of the protocol comprises a multicast port, a multicast address and a multicast VLAN; a module for operating IGMP Snooping Layer 2 Multicast Protocol is arranged on the ONU; the multicast address list item of the protocol comprises a multicast port, a multicast address and a multicast VLAN. The invention also provides the method for realizing a multicast message by using the device; the method adopts the IGMP Snooping Layer 2 Multicast Protocol to process the multicast message on the ONU, transparently transmits all multicast messages on a wiring card and adopts the IGMP Proxy Layer 2 Multicast Protocol to process the multicast message on the main control panel, thereby realizing the multicast function of the EPON access system.

Description

technical field [0001] The invention relates to an EPON access system, in particular to a device and method for realizing multicast in the EPON access system. Background technique [0002] Ethernet Passive Optical System (EPON) is a new type of optical fiber access network technology, which adopts point-to-multipoint structure and passive optical fiber transmission, and provides various services on Ethernet, with high Cost-effective, it can provide end users with reliable data, voice and video services, and can provide up to 1Gbit / s uplink and downlink bandwidth, which can meet the bandwidth needs of users now and in the next 10 years. In addition, EPON adopts multiplexing technology to support more users, and each user can enjoy greater bandwidth. [0003] In recent years, with the increase of access network bandwidth, the application of interactive Internet TV IPTV has become possible. It is a brand-new technology for many kinds of interactive services including digital ...
