Abstract
An apparatus comprising a proxy configured to couple to a sender and a receiver and to receive data from the sender at a first rate and forward the data to the receiver at a second rate that is less than the first rate. A method comprising detecting a reception speed for each of a plurality of receivers in a multicast group, assigning the receivers to a first group and a second group based on the reception speed of each of the receivers, wherein the first group has a reception speed that is faster than a reception speed of the second group, and sending multicast data intended for all of the receivers to the receivers in the first group and to a proxy at a first rate, wherein the proxy buffers the multicast data and sends the multicast data to the receivers in the second group at a second rate.
