Abstract
Disclosed is a system and method for the delivery of multi-unicast communication traffic. A multimedia router is adapted to analyze and identify contents which it handles and one or more access nodes are adapted to receive one or more of the identified contents, cache contents based on said identification; and use cached contents as substitutes for redundant traffic, received by the same access node.
Claims19
An apparatus associated with a data access point, said apparatus comprising:
- first communication circuitry adapted to communicate with each of a set of data client devices;
- a communication module adapted to receive a data stream addressed to a first data client device;
- a data stream generator adapted to generate a data stream addressed to a second data client device, wherein the generated data stream is at least partially based on the data stream addressed to the first data client device;
- and
- control logic adapted to (1) detect when the second data client device requests redundant content, wherein redundant content is content that is already cached locally at the access point or content previously requested by the first data client device and (2) adapted to trigger said stream generator in response to the detection;
- and
- wherein said control logic is adapted to signal an associated network element to halt transmission of a stream including the redundant content and addressed to the second data client device.
4 more elements
A network gateway comprising:
- a first communication module adapted to establish communication sessions with one or more content sources;
- a second communication module adapted to establish a communication session with each of one or more network terminal access nodes;
- routing logic adapted to sniff data stream requests of data client devices connected to a first access node and further adapted to:
- (1) forward through said first communication module the first and the second requests to one or more sources of the requested data stream, (2) forward to the first access node one or more data streams received in response to the forwarded first and second requests, and (3) to halt forwarding of a received data stream in response to redundancy indicative signaling from the first access node.
1 more element
A method of operating a data access point, said method comprising:
- communicating with each of a set of data client devices;
- receiving from first and second data client devices requests for data streams;
- forwarding the received requests to one or more sources of the requested data streams;
- receiving a data stream addressed to the first data client device;
- generating a data stream addressed to the second data client device, wherein the generated data stream is at least partially based on the data stream addressed to the first data client;
- and
- signaling an associated network element to halt transmission of a data stream with redundant content addressed to the second data client device.
