  • Patent number: 11909656
    Abstract: A CPU implements a virtual network function (VNF) associated with flow processing and can offload at least some of the flow processing to a hardware accelerator. A module (e.g., TOR switch), external to the software-based processor and the hardware accelerator, examines packet flows and determines (e.g., using a top-K elephant-flow-detection algorithm) which ones are more suitable for offloading from the software-based processor to the hardware accelerator than others. The external module communicates the relative suitability for offloading to the CPU using packet tags or out-of-band messaging, and the CPU uses the relative suitability to determine which flows to offload or onload. In some implementations, the CPU can instruct the external module to change the value of K used in the algorithm.

  • Patent number: 11909716
    Abstract: Leaf nodes of a tree structure, also having a root node and intermediate nodes, communicate with endpoints via access networks and store mappings from permanent virtual IP (VIP) addresses for the endpoints to physical IP (PIP) addresses for the endpoints on the access networks. The root node and intermediate nodes store pointers for the endpoints' leaf nodes and associated access networks. When a connection setup request (CSR) for a destination endpoint is received from a corresponding node, the receiving leaf node passes the CSR up through the tree structure to a lowest common ancestor (LCA) node for the receiving leaf node and one or more destination leaf nodes associated with the destination endpoint. The LCA node uses its pointers to pass the CSR down towards the one or more destination leaf nodes, which use the corresponding VIP-to-PIP mappings to forward the CSR to the destination endpoint.

  • Patent number: 11910421
    Abstract: A base station that controls carrier aggregation for a user equipment (UE) includes a memory configured to store weight factors for serving cells that are aggregated to provide wireless connectivity to the UE. The weight factors are determined based on characteristics of the serving cells. In some cases, the weight factors are determined based on frequencies of carriers used by the serving cells to provide the wireless connectivity to the UE. The base station also includes a processor configured to determine, based on the weight factors and a total weight assigned to the UE, weights for transmitting data to the UE via the serving cells. The base station further includes a transceiver configured to transmit data to the UE via the serving cells at priorities that are determined based on the weights for the serving cells.

  • Patent number: 11909523
    Abstract: An upstream (US) optical line terminal (OLT) for a passive optical network having at least one downstream (DS) optical network unit (ONU). The OLT generates a trigger signal indicating a need to receive at least one US burst having a shortened codeword for a first forward error-correction (FEC) code. Based on the trigger signal, the OLT transmits a DS message instructing the ONU to transmit an US burst having a shortened codeword. The OLT receives and decodes the US burst having the shortened codeword using the first FEC code. During periods of high bit-error rate, the shortened codewords increase the ability of the OLT to decode the US bursts and keep communications from the ONU alive. The OLT can use the decoded US bursts to measure BER and, if appropriate, instruct the ONU to use a different FEC code.
