Abstract
A method for transmitting packets in an RPR includes: pre-setting an MAC table having an item which is a corresponding relationship between the node MAC address and the UE MAC address of each node; an RPR node receiving an insert packet, performing the MAC table lookup, deciding whether an item matching a destination MAC address of the insert packet exists; if there exists the item, converting the insert packet to an extended frame-formatted packet where the RPR destination node MAC address equals to the node MAC address of the item and sending the converted packet to the destination node, and performing the corresponding process; if there does not exist the item, converting the insert packet to an extended frame-formatted packet where the RPR destination node MAC address equals to a broadcast MAC address, broadcasting the converted packet on the whole network, and performing the corresponding process.
