<p>The present invention discloses a method for controlling switching between an active pseudo-wire and a standby pseudo-wire. In the method, an ARP monitoring module configured on a base station side of a cell-site gateway monitors an ARP packet from the base station side; when an active PW is faulty, an ARP proxy receives a PW redundancy switching message, and sends, according to the redundancy switching message and by using a standby PW, the monitored ARP packet to a PE-AGG2 connected to the standby PW and a UPE2; then, the ARP proxy sends the APR packet to a UPE1, and triggers a corresponding VSI to learn a source MAC address of the ARP packet, so as to switch downlink traffic to the standby PW Accordingly, the present invention also provides an apparatus for controlling switching between an active pseudo-wire and a standby pseudo-wire. When the method and the apparatus provided by the present invention are implemented, switching between an active PW and a standby PW may be no longer determined according to a frequency of a heartbeat packet, thereby ensuring that time of traffic switching between the active PW and the standby PW is controllable.</p> |
