Abstract
A system and method for multicast transmission are disclosed. In one embodiment, a virtual exchange network including interconnected nodes is embedded within a network. A sender is disposed in communication with a root node and receivers are disposed in communication with a set of edge nodes. The sender publishes a packetized data stream to which the receivers subscribe. The packetized data stream is promulgated by implicit signaling through optimum virtual exchange network connections from the sender through the virtual exchange network to the receivers. The interconnected nodes, responsive to receiving the published packetized data stream, are adapted to multicast N instances of the published packetized data stream to N recipients selected from the group consisting of receivers and other of the interconnected nodes.
