  • Patent number: 11683276
    Abstract: In one embodiment, quasi-Output Queue behavior of a packet switching device is achieved using virtual output queue (VOQ) ordering independently determined for each particular output queue (OQ), including using maintained latency information of the VOQs of the particular OQ. In one embodiment, all packets from all VOQs with a same port-priority destination experience similar latency within specific time-window, which is similar to the packet service provided by an Output Queue switch architecture. In one embodiment, all input ports that send traffic to same output port-priority receive bandwidth which is proportional to their bandwidth demand divided by total bandwidth. Prior approaches that emulate the performance of an OQ switch architecture require complex and time-consuming scheduling determinations and do not scale. Independently determining the order for sending packets from the VOQs associated with each particular OQ provides a scalable and implementable system with quasi-Output Queue behavior.

  • Patent number: 11637787
    Abstract: In one example, a collection network node comprising a plurality of ingress ports obtains, at a first one of the plurality of ingress ports, a first copy of a packet of a packet flow comprising a plurality of packets. The collection network node determines whether the collection network node had previously obtained a copy of any of the plurality of packets of the packet flow. When it is determined that the collection network node had previously obtained a copy, the collection network node determines whether the collection network node had previously obtained a copy at the first one of the plurality of ingress ports or at a different one of the plurality of ingress ports. When it is determined that the collection network node had previously obtained a copy at a different one of the plurality of ingress ports, the collection network node refrains from forwarding the first copy.

  • Patent number: 11528227
    Abstract: A system for facilitating an enhanced traffic profile is provided. During operation, the system can determine a first traffic profile indicating whether to drop a packet based on the utilization of a queue. The packets from the queue can be forwarded via an egress port reachable via a fabric. The system can also determine a second traffic profile indicating whether to indicate congestion in the packet based on the utilization. The system can then determine a third traffic profile by combining the first and second traffic profiles. The third traffic profile can indicate acceptance at the queue for a subset of packets with a low-level congestion indicator or selected for dropping based on the utilization. Subsequently, the system can, if the packet is selected for dropping, determine whether to accept the packet at the queue with a high-level congestion indicator in the packet based on the third traffic profile.

  • Patent number: 11528727
    Abstract: A wireless device receives a radio resource control message. The radio resource control message comprises a periodicity of uplink resources of an uplink configured periodic grant. A buffer status report (BSR) for transmission is triggered in response to data becoming available for uplink transmission. The BSR indicates a size of the data. Based on the triggering of the BSR, an uplink scheduling request is triggered in response to receiving no additional resource for uplink transmission while the uplink resources for the uplink configured periodic grant are available. The scheduling request is transmitted.

  • Patent number: 11522804
    Abstract: A method and system for providing robust streaming of data from a multi-core die is disclosed. The techniques include using a high bandwidth memory (HBM) device as retransmit buffers for large amounts of data to ensure robust communication in relatively high round trip-transmission time (RTT) transmission. Another technique is supporting two or more Ethernet ports between components to both transmit the same data packets on the two ports to insure robustness. Another technique is to use sequence numbers and send data packets from the different ports in a round robin fashion and reorder the packets upon receipt of an external device. Another technique is dynamically adding and removing paths for data packets between devices with multiple ports based on the quality of the path.

  • Patent number: 11516152
    Abstract: A method of segmented media data processing can include receiving a first sequence of first segments partitioned from a first data stream of a streaming media, and storing the first segments into a first first-in first-out (FIFO) buffer. In the first FIFO buffer, each first segment and attributes associated with each first segment form an entry of the first FIFO buffer. The attributes associated with each first segment can include a start time of the respective first segment, a duration of the respective first segment, and a length of the respective first segment indicating a number of bytes in the respective first segment. The first segments received from the first FIFO buffer can be processed using a first media processing task of a workflow in a network-based media processing (NBMP) system. The first segments received from the first FIFO buffer can be processed independently from each other.

  • Patent number: 11516144
    Abstract: Incremental data processing at a computerized device includes determining a number of data sets from a plurality of data sets, each comprising values in at least two dimensions. The device accesses priority lists for a subset of the data sets. The priority lists specify data values for an ordered number of dimension value sets. Each priority list is sequentially processed to determine the specified data values for combinations of dimension values that apply to device requirements. Processing is aborted when a data value is determined for each combination of the dimension values that apply to the device requirements. A data value is selected among the determined data values. A number of data sets is determined based on the selected data values. A network route from a source device to a target device can be determined in this manner.
