Abstract
A method for multicasting data packets is provided. The method includes preparing multiple point to point connections between a root node and multiple destination nodes to establish point to multipoint connections. The method also includes receiving, at an intermediate node which is operatively connected to the root node and a plurality of the destination nodes, a data packet from the root node. In addition, the method includes determining whether the received data packet is a multicast data packet and generating a plurality of the data packets by copying the received data packet if the received data packet is a multicast data packet. Furthermore, the method includes forwarding the copied data packets to a plurality of the destination nodes.
