GRACEFUL RECOVERY OF A MULTICAST-ENABLED SWITCH

摘要

One embodiment of the present invention provides a switch. The switch includes a processor, a storage device, a multicast management module, and a graceful recovery module. The multicast management module participates in a multicast tree of a multicast group. The graceful recovery module determines a recovery event and constructs a message indicating the recovery event for a second switch. The switch and the second switch belong to a first virtual local area network (VLAN). The graceful recovery module then identifies a completion notification message from the second switch indicating a completion of replaying multicast information stored in the second switch and includes multicast information received from the second switch in a local multicast database.

1. A switch, comprising:
a multicast management module configured to participate in a multicast tree of a multicast group; and a graceful recovery module configured to:
in response to determining a recovery event, construct a message indicating the recovery event for a second switch, wherein the switch and the second switch belong to a first virtual local area network (VLAN);identify a completion notification message from the second switch indicating a completion of replaying multicast information stored in the second switch; andinclude multicast information received from the second switch in a local multicast database.
