  • Traffic forwarding
    Patent number: 10419241
    Abstract: The present disclosure describes traffic forwarding in a network where a virtual local area network (VLAN) exists in multiple network sites that are geographically dispersed and connected via virtual links. A first edge device (ED) at a first site receives, from a second ED at a second site, information identifying a VLAN of the second ED through a virtual link. The VLAN identified in the information is an active VLAN of the second ED. An association between (i) the VLAN of the second ED and (ii) the virtual link through which the information is received from the second ED is recorded. When forwarding traffic to the VLAN of the second ED, it is determined the virtual link associated with the VLAN of the second ED is determined based on the recorded association and the traffic is forwarded via the determined virtual link.

  • MIGRATING MULTICAST FLOW
    Publication number: 20160094367
    Abstract: A first BEB device may receive a first LSP packet transmitted from each second BEB device. According to the received first LSP packet, the first BEB device may calculate multicast tunnel information of the service instance from the first BEB device to the second BEB device in the second B-VLAN. The first BEB device may update multicast tunnel information of the service instance in a data plane according to the multicast tunnel information of the service instance from the first BEB device to the second BEB device.
