Multicast delivery based on unicast and subnet multicast
Jinhae Park, Seok‐Joo Koh, Shin‐Gak Kang, Dae Young Kim · IEEE Communications Letters · 2001
In spite of the numerous works previously made, IP multicasting has not been widely deployed in the public Internet. We present a realistic alternative scheme for IP multicasting, which is based on the unicast transport from a remote sender to a local subnet and the multicast forwarding to receivers within the subnet.
