Abstract
When a User Edge Device (UED) receives a unicast packet from a user side, the UED searches in a Media Access Control (MAC) table. When a matching entry in the MAC table is found, the UED forwards the unicast packet locally. When no matching entry in the MAC table is found, the UED transmits the unicast packet to a Network Edge Device (NED). When the UED receives a broadcast packet from the user side, the UED broadcasts the broadcast packet within a same Virtual Local Area Network (VLAN) of a local site and forwards to the NED.
