Problems solved by technology

In this implementation, the virtual device created by the cross-vlan multicast vlanid and the virtual device created by the wan connection vlanid bound to the cross-vlan multicast service are added to a bridge device. If the data in the bridge device is not Restrictions will inevitably lead to loops, leading to failures, and adding rules to restrict data forwarding through ebtables (Ebtables is the Ethernet bridge firewall, and Ethernet bridges work at the data link layer) will inevitably affect the efficiency of data forwarding

Embodiment Construction

[0020] Such as figure 1 As shown, this implementation patent is a cross-vlan multicast technology realized by replacing the vlanid of the cross-vlan multicast data message with the wan connection vlanid at the EPON home gateway driver layer, specifically including starting the EPON home gateway and initializing the driver layer Save the data structure of cross-vlan multicast vlanid and wan connection vlanid, start the application, save the cross-vlan multicast vlanid and wan connection vlanid in the corresponding data structure of the driver layer, replace the vlanid of cross-vlan multicast data packets with cross-vlan groups The broadcast service is bound to the vlanid of the wan connection, the EPON home gateway completes data forwarding, and the terminal equipment on the lan side completes the multicast program playback. The steps of this method include:

[0021] A. When the system starts, the driver layer initializes and saves the data structure of cross-vlan multicast vl...

Abstract

The invention provides an implement method for trans-VLAN multicast in an EPON home gateway. When starting the EPON home gateway, a data structure for storing a trans-vlan multicast vlan id and a wan connecting vlan id is initiated first in a driving layer. After an application layer is started, the trans-vlan multicast vlan id and the wan connecting vlan id are transmitted to the driving layer and saved in the initiated data structure of the driving layer. After a multicast data message containing the trans-vlan multicast vlan id reaches to a wan side of the EPON home gateway, the trans-vlan multicast vlan id in the multicast data message is replaced with the wan connecting vlan id in the driving layer and then the multicast data message reaches to a terminal device on a lan side of the EPON home gateway after processing. Therefore, playing of multicast programs is completed. Loop problems caused by creating virtual devices for the wan connecting vlan id and the trans-vlan multicast vlan id respectively and adding the virtual devices to a bridge device can be solved effectively. The beneficial effects of the implement method provided by the invention is that the whole process can be realized simply and the method can be applied easily; and other services of the EPON home gateway are not influenced and stability of the EPON home gateway performance is guaranteed.

Description

technical field [0001] The invention relates to a multicast control technology of EPON home gateway data communication, in particular to a realization method of EPON home gateway cross-vlan multicast. Background technique [0002] In the field of communication technology, with the vigorous promotion of national triple network integration, multicast IPTV service has become a very important basic service of EPON home gateway (usually including: voice, broadband, multicast, TR069 four services). Based on IGMPSnooping (the abbreviation of InternetGroupManagementProtocolSnooping (Internet Group Management Protocol Snooping), it is a multicast constraint mechanism running on the second-layer device, used to manage and control multicast groups.) and IGMPProxy (IGMPProxy is to intercept the relationship between users and routers The uplink port of the Proxy device performs the role of the host, and the downlink port performs the role of the router) function effectively solves the pr...
