ACKNOWLEDGED MULTICAST CONVERGENCE

摘要

In one embodiment, a device connected to a network as part of a multicast tree receives a revised unicast routing and distributes the revised unicast routing and a query packet to a downstream device in the multicast tree. The device receives an acknowledgement message from the downstream device based on the query packet and determines a new multicast route based on the revised unicast routing and the acknowledgement message from the downstream device.
