Abstract: A system may receive information indicating that an amount of content, buffered by a user device, is below a threshold amount that is associated with an attribute of the content; and/or information indicating that delivered content exceeds capabilities of the user device. The content may be provided to the user device by a content delivery network (“CDN”). The system may determine whether the CDN has available resources to provide the content to the user device at a bandwidth that is based on the attribute; instruct, when the CDN has the available resources, the CDN to reallocate resources to provide the content to the user device at the particular bandwidth; and switch, when the CDN does not have the available resources, delivery of the content to another CDN. The system may have a global of view of CDNs, and may reallocate CDN resources more intelligently, thus optimizing network resource utilization.

Abstract: Device and method for scheduling traffic exchange in a passive optical network, PON, to reduce energy consumption. The method includes a step of instructing an optical network terminal, ONU, and an optical line terminal, OLT, in the PON to maximize an overlap between upstream and downstream communications by exchanging a predetermined future time (t2) at which to start the upstream and downstream communications; a step of sending to the ONU a predetermined time interval (G) during which the ONU need to have a transmitter and a receiver on; and a step of adding a flag (MPSMP) to a control message sent from the OLT to the ONU that is indicative of whether further messages are to be received from the OLT or not.

Abstract: A network element implementing an optical network unit (ONU) that is configured to improve efficiency in a passive optical network (PON), the ONU connected to an optical line terminal (OLT) over an optical line, the ONU connected with an aggregating ONU (AG-ONU) in the PON through an alternate connection separate from the PON, the ONU improving protection (maintenance) cost and energy efficiency for the PON by entering a sleep mode that disables communication with the OLT over the optical line to reduce energy consumption when the ONU is idle, the ONU to restart communication with the OLT over the optical line upon receipt of data traffic, the ONU including an alternate connection module configured to communicate with the AG-ONU; and a network processor configured to execute a quality of service module, an AG-ONU monitor module, a traffic forwarding module and a power management module.
