  • Patent number: 10341241
    Abstract: Methods and systems of history-based instantaneous QoS class classification of traffic flow. QoS classifications are mapped to target destinations such that, when a first flow parcket packet of a traffic flow requesting access to a resource associated with the target destination, a classifier can instantaneously classify the traffic flow as belonging to a particular QoS class for servicing of the traffic flow.

  • Publication number: 20190199818
    Abstract: An approach for cached content identification for adaptive data streaming. A first request is received, requesting a current segment from a sequence of segments from a data file of a streaming data session. A NewVideoFlag is determined as indicating that the sequence of segments associated with the first request is not currently being cached. The first request is forwarded to a content server, and a first response message is received. A SegmentID of the received content segment is determined as not matching that of cached content segments. The NewVideoFlag is set to indicate that the segments from the streaming data session file are currently being cached. A global cVideoFileID is generated identifying the streaming session data file being cached. The content segment is cached, and cache bookkeeping is updated to associate the segment with the SegmentID and the cVideoFileID. The first response message is provided to the client device.

  • Patent number: 10021034
    Abstract: A method for application aware multihoming with multipath tunneling protocols is provided. A message client data packet is classified based an application from which the data packet originated. The header structure of the data packet is modified to generate a proxy data packet comprising the client data payload and a proxy header structure. The proxy header structure comprises source-client and destination-server parameters and an identifier of a client-proxy device, protocol parameters indicating a source protocol sequencing of the message client data packet, and protocol parameters including source parameters of the client-proxy device and destination parameters of a server-proxy device. A network communications link is selected for transmission of the proxy data packet to the server-proxy device, where the selection is based on the classification of the message client data packet. The proxy data packet is transmitted to the server-proxy device via the network communications link.

  • Publication number: 20170318066
    Abstract: A system and method are provided for use with streaming blocks of data, each of the streaming blocks of data including a number bits of data. The system includes a first compressor and a second compressor. The first compressor can receive and store a number n blocks of the streaming blocks of data, can receive and store a block of data to be compressed of the streaming blocks of data, can compress consecutive bits within the block of data to be compressed based on the n blocks of the streaming blocks of data, can output a match descriptor and a literal segment. The match descriptor is based on the compressed consecutive bits. The literal segment is based on a remainder of the number of bits of the data to be compressed not including the consecutive bits. The second compressor can compress the literal segment and can output a compressed data block including the match descriptor and a compressed string of data based on the compressed literal segment.

  • Publication number: 20170195450
    Abstract: An approach for opportunistic caching of streaming media data is provided to facilitate efficient use of forward transmission resources of a broadband communications system. The approach includes receiving, by a second communications terminal, a first content response transmitted by a first content server, via a broadcast/multicast communications medium, in response to a first content request of a first client device associated with a first communications terminal, wherein the first content response includes first data content requested by the first client device via the first communications terminal. The approach further comprises determining, by a cache controller of a cache storage device of the second communications terminal, to store at least the first data content of the first content response in the local cache storage device associated with the second communications terminal, wherein the determination to store is based on one or more criteria associated with the first content response.

  • Publication number: 20170195393
    Abstract: Application layer throughput (ALT) shaping is provided for a streaming media session is provided. A request for a content segment is received. The receipt time of the request is recorded and the request is forwarded to a content server. A response message is received from the server. The receipt time of the response and a segment size is determined. An ALT for the current segment is determined based on the receipt times of the request and response messages and the segment size. The ALT rate is compared to a target ALT rate required for a desired session PBR. When the ALT rate is higher than the target ALT rate, the content response is held for a time period determined to lower the current ALT rate to the target ALT rate, and then released to the client device. Otherwise, the content response is promptly provided to the client device.

  • Patent number: 9680500
    Abstract: Approaches for staged data compression are provided, where each stage reflects a progressive increase in granularity, resulting in a scalable approach that exhibits improved efficiency and compression performance. The first stage comprises a long-range block-level compressor that determines redundancies on a block-level basis (based on entire data blocks, as opposed to partial segments within data blocks). The second stage comprises a long-range byte-level compressor that compresses an uncompressed block based on byte segments within the block that match previously transmitted segments. The duplicate segments are replaced with pointers to matching segments within a decompressor cache. Nonmatching segments of the data block are left uncompressed and passed to a third stage short-range compressor (e.g., a grammar-based compressor). The staged progression in granularity provides advantages of maximizing the compression gain while minimizing processing and storage requirements of the compressor and decompressor.

    Abstract: Approaches for determining link conditions within a client network are provided. Network protocol statistics are recorded for network connections over the client network, wherein each connection provides data communications between a client terminal node and a different respective client device, and the client terminal node provides access to a broadband communications network for each of the different respective client device(s). Connection metrics are determined for each of the network connections, wherein each connection metric is determined based on the network protocol statistics associated with the respective network connection. Diagnoses of network conditions regarding connections over the client network that are of interest, wherein each diagnosis is performed based on an analysis of a respective set of the connection metrics for the respective network connection. Results of each diagnosis are provided to a system operator.
