Each PE further selects one of the PEs in the VPN instance as a root bridge, calculates a broadcast minimal spanning tree by taking the root bridge as a root, and generates a broadcast MAC table in the VPN instance according to the broadcast minimal spanning tree. | 2016-01-28 |
20160028622 | NETWORK PATH SETUP METHOD BASED ON IDENTIFIER, AND APPARATUS THEREOF - Exemplary embodiments of the present invention relate to a network path setup method based on identifier and apparatus thereof. A network path setup method in a repeater equipment, the method comprising: receiving a packet; determining whether source/destination node identifiers included in the received packet are stored in a routing table; and updating the routing table based on a node identifier and a port number which is used for packet transmission to the node when it is determined as that the node identifier is not stored. According to exemplary embodiments of the present invention, it simplifies a routing table to quickly search packet paths and reduces traffics since it does not require to define an additional header. | 2016-01-28 |
