Abstract:
1. A method comprising: receiving a request from a receiver node in a network to receive a first multicast stream, wherein the first multicast stream has a first bandwidth and is transmitted by a multicast source in a first multicast group, and wherein the receiver is configured to receive using a second bandwidth that is different from the first bandwidth; responsive to receiving the request, determining that the first bandwidth is different from the second bandwidth; based on determining that the first bandwidth is different from the second bandwidth, redirecting the request to a content engine node in the network; receiving, from the content engine node, a second multicast stream having a third bandwidth and being associated with a second multicast group, wherein the second multicast stream is a modified version of the first multicast stream, the modified version including modifying a parameter group that includes the first bandwidth, a first format of the first multicast stream and an identifying information of the first multicast stream, and wherein the second multicast stream is available in the second multicast group using the third bandwidth while the first multicast stream is available in the first multicast group using the first bandwidth; based on receiving the second multicast stream, subscribing the receiver node as a member of the second multicast group; and forwarding the second multicast stream to the receiver node.
