A multicast relay system for use in a wide area network, includes an input receptive of multicast data specifying a multicast channel having a multicast address. A proxy election module is adapted to elect a multicasting server proxy disposed within a subnet associated in memory with the multicast channel, wherein the multicasting server proxy is adapted to receive the multicast data and multicast the multicast data on the multicast address within the subnet. A multicast data relay module is adapted to transmit the multicast data to the multicasting server proxy.
