Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

In one embodiment, a method comprises a network device detecting an event severity encountered by the network device; the network device selectively changing a window size, for a maximum number of unacknowledged data packets that can be sent by the network device to a receiver device, to correspond to the event severity encountered by the network device; and the network device transmitting, to the receiver device, a number of data packets up to the window size, enabling the receiver device to detect the corresponding event severity encountered by the network device based on the number of unacknowledged data packets received by the receiver device from the network device.

Aspects of the present disclosure are directed to dynamically adjusting control plane policing throughput of low (or lower) priority control plane traffic to permit higher throughput. The drop rate for low or lower priority control plane traffic can be determined to be above a threshold value. The processor utilization can be determined to be operating under normal utilization (or at a utilization within a threshold utilization value). The control plane policing for control plane traffic for the low or lower class of service can be increased (or decreased) to permit lower class of service control traffic to be transmitted using higher class of service resources without adjusting the priority levels for the lower class of service control traffic.

Systems and methods for mapping a time-based data acquisition (DAQ) to an isochronous data transfer channel of a network. A buffer associated with the isochronous data transfer channel of the network may be configured. A clock and a local buffer may be configured. A functional unit may be configured to initiate continuous performance of the time-based DAQ, transfer data to the local buffer, initiate transfer of the data between the local buffer and the buffer at a configured start time, and repeat the transferring and initiating transfer in an iterative manner, thereby transferring data between the local buffer and the buffer. The buffer may be configured to communicate data over the isochronous data transfer channel of the network, thereby mapping the time-based DAQ to the isochronous data transfer channel of the network.

A computer-implemented system and method identifies a network flow direction. The method includes observing, by a network flow monitor, a plurality of data packets as each data packet travels past a connection point. The method further includes identifying, from the plurality of data packets, a flow session, wherein the flow session comprises a source port, a source device, a destination device, a destination port, and a communication protocol. The method also includes, gathering, from the plurality of data packets, directional metadata. The method includes, comparing the source port and the destination port against a list of common destination ports. The method further includes determining, based on the plurality of data packets, a flow direction of the flow session. The method includes storing the flow session in a database.

A novel and useful acknowledgement and adaptive frequency hopping mechanism for use in wireless communication systems such as IO-Link Wireless. One or two additional acknowledgement bits are added to packet transmissions. One is a current acknowledgment bit which indicates whether a packet was successfully received anytime during the current cycle. The second bit is a previous acknowledgment bit which indicates whether packets were received successfully anytime during the previous cycle. An adaptive hopping table is constructed using a greedy algorithm which chooses frequencies with the best PER for transmission of higher priority packets, while equalizing the PER products across cycles. A last resort frequency mechanism further improves transmission success by switching to a better performing channel for the last subcycle when previous attempts to transmit a high priority packet have failed.

A packet processing device includes: a non-priority packet storage that stores the non-priority packet; a gate provided on an output side of the non-priority packet storage; plural priority packet storages that respectively store the priority packet; a distributer that guides a received priority packet to a priority packet storage corresponding to a delay time of a route through which the received priority packet is transmitted; a timing setting unit that sets different read cycles to respective priority packet storages; a read controller that reads priority packets from the plural priority packet storages according to the read cycles; and a gate controller that controls the gate according to the timings on which the read priority packets are output. When the read controller reads a first priority packet from one of the priority packet storages, the read controller reads a second priority packet from another priority packet storage.

Methods, systems, and devices for wireless communications are described. In aspects, a wireless device such as a user equipment (UE) may identify an amount of acknowledgement (ACK) reduction associated with an applications processor. The amount of ACK reduction may be determined based on a communication from the applications processor, or an ACK frequency in a group of packets received from the applications processor. The UE may determine whether to modify an ACK management scheme (e.g., a transmission control protocol (TCP) ACK coalescing scheme) based at least in part on the amount of ACK reduction associated with the applications processor. The UE may modify the ACK management scheme. The UE may transmit ACKs in accordance with the modified ACK management scheme. Numerous other aspects are provided.

A computing system includes a core system and an uncore system. The core system includes a packet generator unit configured to generate a data packet having a plurality of bytes defining a target packet size, and to output a first byte among the plurality of bytes at a packet delivery start time. The uncore system includes an input/output (I/O) bridge configured to connect an I/O component to the core system, and a packet monitor unit configured to monitor the bytes delivered from the packet generator unit to the I/O component. The packet monitor unit further determines a packet delivery end time after detecting a last byte of the data packet. The computing system determines a latency attributed to the uncore system and the I/O bridge based on the packet delivery start time and the packet delivery end time.

A method for accelerating TCP/UDP packet switching. The method involves determining whether exception processing is necessary; if not, the packet is forwarded to a special stack for expedited processing. Packets requiring exception processing are forwarded to the conventional stack.
