摘要： A technique efficiently selects a path computation element (PCE) to compute a path between nodes of a computer network. The PCE selection technique is illustratively based on dynamic advertisements of the PCE's available path computation resources, namely a predictive response time (PRT). To that end, the novel technique enables one or more PCEs to dynamically send (advertise) their available path computation resources to one or more path computation clients (PCCs). In addition, the technique enables the PCC to efficiently select a PCE (or set of PCEs) to service a path computation request based upon those available resources.

摘要： One embodiment includes receiving a notification at a communications network node; determining a lowest cost path for implementing a next hop for the notification; determining a best alternate path for the next hop; comparing a cost of the best alternate path with a value stored in a notification header field; updating the header field value to equal the cost of the best alternate path if the cost of the best alternate path is less than the header field value; and forwarding the notification along the lowest cost path. Some embodiments include receiving a NACK at the node; comparing a cost of the best alternate path with a NACK header field value; and retransmitting the notification along the best alternate path if the NACK header field value is greater than or equal to the cost of the best alternate path.

摘要： Techniques are provided for optimizing quality in adaptive streaming, where information is obtained relating to encoding bitrates and content quality scores for content segments of a content stream. The content segments of the content stream are provided by a content server and downloaded by a computing device. For each content segment, an encoding bitrate is determined for downloading the content segment from the content server, where determining the encoding bitrate for a current content segment is based upon an estimated current network bandwidth, constraints of a buffer into which downloaded content segments are stored, and also upon quality scores associated with content segments within a selected horizon extending from the current content segment to a future content segment in the content stream at an endpoint of the horizon. Each content segment with the determined bitrate for the content segment is downloaded from the content server.

摘要： Content is received within a network by a content receiver based upon fetch requests by the content receiver to a content source, where the fetch requests for content are based upon a first adaptation logic scheme to fill a buffer of the content receiver at a selected rate and to download segments of content at selected encoding rates. A network priority is detected at the content receiver that includes an observed download rate at the content receiver that is greater than a fair share rate for other content receivers in the network. Fetch requests for content are revised in response to detection of the network priority, where the revised fetch requests are based upon a priority adaptation scheme that results in at least one of filling the buffer at a faster rate and downloading segments of content at higher encoding rates compared with the first adaptation logic scheme.

摘要： Congestion aware load balancing for distributed storage may be provided. First, a read request for data may be received. The data may have redundancy through coding or through copying. Then it may be determined which K of M possible storage nodes to direct the received read request. K and M may be integers and M may be greater than K. In response to determining which K of M possible storage nodes to direct the received read request, the received read request may be copied into K read requests respectively corresponding to the determined K of M possible storage nodes. The copied K read requests may then be transmitted to the determined respective K storage nodes. And, in response to transmitting the copied K read requests, a client may receive data replies from each of the determined respective K storage nodes.

摘要： Embodiments include technologies for identifying an equivalence class identifier in a packet received by a node configured to perform information centric networking (ICN) in an ICN network, where the packet includes a name identifying content associated with a producer node in the ICN network. Embodiments also include determining an equivalence class for the packet by determining a name prefix of the name based, at least in part, on the equivalence class identifier. Embodiments further include taking an action affecting a particular packet, the action based, at least in part, on the equivalence class. In specific embodiments, the name includes a plurality of name components, and the equivalence class identifier is a count indicating a number of name components in the name to be grouped together to determine the name prefix. In further embodiments, the number is greater than a particular number of name components in a routable name prefix.

摘要： Aspects of the disclosure are directed to systems, network nodes, and methods performed in a network node. A network node can host a TCP/ICN proxy for routing TCP packets through an ICN network. The network node can serve as a forward proxy or a reverse proxy. As a forward proxy, the network node can receive a first packet at the network node, the first packet compliant with a Transmission Control Protocol (TCP) protocol; encapsulate one or more TCP headers from the first packet into a payload field of a second packet, the second packet compliant with an Information Centric Networking (ICN) protocol; and transmit the second packet to a destination through an ICN network. As a reverse proxy, the network node can receive an ICN packet from an ICN network, decapsulate the ICN packet to its TCP components, and transmit the TCP packet through a TCP network.
