ABSTRACT:
A network device for controlling data flow can have a buffer configured to receive a packet, a first determining unit configured to determine a multicast group number from the packet, a first table storage unit configured to store at least one first bit vector and at least one first pointer, and configured to have the multicast group number indexed thereto, and a second table storage unit configured to store at least one second bit vector and at least one second pointer, and configured to have the at least one first pointer indexed thereto. In addition, the device can have a generating unit configured to generate at least one first network identifier based on the at least one first bit vector and the at least one second bit vector, a replication unit configured to replicate the packet for the at least one first network identifier, and a first forwarding unit configured to forward a replicated packet replicated by the replication unit to a network destination associated with the at least one first network identifier.
