1. A computer-implemented method for multicasting information, comprising: receiving at an access router multicast information for a multicast session encoded at a first bitrate wherein the information is addressed to a multicast group; transmitting the multicast information encoded at the first bitrate to a first portion of the multicast group serviced by the access router, wherein the transmitting is on a first set of paths serviced by the access router that reaches the first portion of the multicast group, and wherein the first set of paths comprises one or more paths serviced by the access router; and transmitting the multicast information encoded at a second bitrate to a second portion of the multicast group serviced by the access router, the second bitrate lower than the first bitrate, wherein the transmitting is on a second set of paths serviced by the access router that reaches a second portion of the multicast group different from the first portion of the multicast group, and wherein the second set of paths comprises one or more paths serviced by the access router.
