US 8,711,856 B2 · Method and device for processing broadcast packets/multicast control messages

Abstract

The present invention discloses a method for processing broadcast packets/multicast control messages, comprising: replicating data to different broadcast/multicast logical channels in accordance with ONU types of users who join a VLAN when an OLT, on which a same port is connected to different types of ONUs, transmits the downlink broadcast packets/multicast control messages. The present invention also discloses a device for processing broadcast packets/multicast control messages. In accordance with the present invention, efficient processing of downlink broadcast packets and multicast control messages is realized when different types of ONUs coexist, unnecessary interference with ONUs from excessive data is avoided, and meanwhile the bandwidth between an OLT and an ONU can be utilized efficiently and meaningless bandwidth occupation by data streams can be avoided.

Dependent claims

A method for processing broadcast packets/multicast control messages, comprising:

establishing information entries in an optical line terminal (OLT);
finding a virtual local area network (VLAN) entry corresponding to a VLAN tag carried in the broadcast packets/multicast control messages according to the information entries when the OLT receives the downlink broadcast packet/multicast control message data;
determining OLT ports corresponding to the VLAN according to the VLAN entry and determining optical network units (ONUs) types of users who join the VLAN under a same OLT port;
replicating data to different broadcast/multicast logical channels in accordance with ONU types of users who join the VLAN under the same OLT port when transmitting of the downlink broadcast packet/multicast control message by determined OLT ports.
