Abstract
A network device includes multiple ports, for communicating over a communication network, and packet processing circuitry. The packet processing circuitry is configured to receive via the ports packets belonging to a plurality of multicast flows, to receive, for each of the multicast flows, (i) a first configuration that specifies clients that are to receive the multicast flow prior to a specified switch-over time, and (ii) a second configuration that specifies the clients that are to receive the multicast flow after the specified switch-over time, to forward the multicast flows via the ports in accordance with the first configuration, to extract from a field in at least one of the packets a value that is indicative of the switch-over time, and, based on the extracted value, to switch-over forwarding of the multicast flows from the first configuration to the second configuration simultaneously at the switch-over time.
