Abstract
A network device detects a multicast video stream being from an upstream resource being sent to downstream multicast members. If the number of multicast members are below a threshold (e.g., 5 stations), multicast network packets can be converted to unicast network packets. On the other hand, if the number of multicast members are above the threshold, the multicast members are divided into groupings based on capabilities of the multicast members, such as data rate capability. Data rates of transmissions are set according to the group data rate capabilities. As a result, the higher data rate members are able to operate at a higher speed rather than at the lowest common denominator. Further, because there are several multicast streams being sent, packets missed from the higher data rate stream can be picked up on the lower data rate stream.
