  • Patent number: 11245632
    Abstract: Packet-switching operations in a network device are managed based on the detection of excessive-rate traffic flows. A network device receives a data unit, determines the traffic flow to which the data unit belongs, and updates flow tracking information for that flow. The network device utilizes the tracking information to determine when a rate at which the network device is receiving data belonging to the flow exceeds an excessive-rate threshold and is thus an excessive-rate flow. The network device may enable one or more excessive-rate policies on an excessive-rate traffic flow. Such a policy may include any number of features that affect how the device handles data units belonging to the flow, such as excessive-rate notification, differentiated discard, differentiated congestion notification, and reprioritization. Memory and other resource optimizations for such flow tracking and management are also described.

  • Patent number: 11197344
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.
