Abstract
A client device is configured to: receive a list of multicast channels from a multicast controller, the list of multicast channels identifying multicast channels to be multicast to a plurality of clients in the access network; receive an updated list of multicast channels from the multicast controller; identify differences between the list of multicast channels and the updated list of multicast channels; and inform the termination node of differences between the list of multicast channels and the updated list of multicast channels.
Claims20
A client device in an access network, which terminates on a core network via a termination node, the client device comprising:
- a memory storing computer-readable instructions;
- and
- one or more processors coupled to the memory, the one or more processors configured to execute the computer-readable instructions to
- receive a list of multicast channels from a multicast controller, the list of multicast channels identifying multicast channels to be multicast to a plurality of clients in the access network,
- receive an updated list of multicast channels from the multicast controller,
- identify differences between the list of multicast channels and the updated list of multicast channels, and
- inform the termination node of differences between the list of multicast channels and the updated list of multicast channels.
An access node configured to communicate with a northbound node and an access network, the access node comprising:
- a memory storing computer-readable instructions;
- and
- one or more processors coupled to the memory, the one or more processors configured to execute the computer-readable instructions to
- identify a request for a multicast channel within the access network, from a client in the access network,
- determine that the multicast channel is in a list of multicast channels for the access network, in response to identifying the request for the multicast channel within the access network, and
- stream the multicast channel to the client in the access network based on the determination that the multicast channel is in the list of multicast channels for the access network.
A client device in an access network, the client device comprising:
- a local cache;
- a memory storing computer-readable instructions;
- and
- one or more processors coupled to the memory, the one or more processors configured to execute the computer-readable instructions to
- determine that a requested chunk of video content is not present in the local cache,
- determine a multicast channel corresponding to requested chunk of video content,
- determine that the multicast channel is in a list of multicast channels to be multicast to a plurality of clients in the access network, and
- issue a request for the multicast channel based on the determination that the multicast channel is in the list of multicast channels.
