Patent number: 9838459Abstract: A content controller monitors current network capacity usage and ongoing streaming data requests. Based on the collected information, the content controller assigns a data segment prefetching task to a data storage (e.g., a cache) of the network.

Patent number: 9825860Abstract: A flow-driven forwarding strategy includes receiving an Interest packet, where the interest packet includes a flow state indicator. The content associated with the Interest packet is checked to determine whether that content is locally stored.

In response to the content not being locally stored and no related Interest packet has been previously received, the flow state indicator is checked in the Interest packet. In response to the flow state indicator indicating that the Interest packet is associated with an active flow, forwarding information is extracted from a flow state table if a hop count has a value of zero or from the Interest packet if the hop count has a value greater than zero. The Interest packet is then forwarded to a next hop in accordance with the forwarding information.Type: GrantFiled: May 28, 2015Date of Patent: November 21, 2017Assignee: Futurewei Technologies, Inc.Inventors: Aytac Azgin, Ravishankar Ravindran, Guo-Qiang Wang

Patent number: 9825856Abstract: Service function chaining is a sequence of service function instances that traffic flows need to traverse through in order. Those service function instances are not required to reside on the direct path and traffic flow, but steered through network nodes.
