A method for parsing network packets via one or more clusters configured to parse network packets comprises receiving one or more packets to be parsed; determining a candidate cluster of the one or more clusters for parsing the one or more packets; transmitting the one or more packets to the candidate cluster; launching the candidate cluster to parse the one or more packets when a launch condition is met; and receiving parse results for the one or more packets from the candidate cluster. The launch condition may be met after transmitting the one or more packets meets a fraction of a parsing capacity of the candidate cluster. The fraction may be one such that the transmitting the one or more packets meets a parsing capacity of the candidate cluster. The launch condition may also be met when a time elapsed since a previous cluster was launched reaches a delay limit.

From received data packets intended for a target virtual machine of a virtualization system, a destination network address of the target virtual machine is determined, and a current write buffer pointer is identified that points to a buffer associated with the identified target virtual machine corresponding to the destination network address. If the identified write buffer pointer indicates that the buffer has sufficient available space to accept the data packets, and if the associated buffer has sufficient available space, the data packets are placed in the associated buffer in buffer data locations according to a calculated new write buffer pointer value, and a wakeup byte data message is sent to a designated socket of the target virtual machine. Generally, the target virtual machine detects the wakeup byte data message at the designated socket and, in response, retrieves the data packets from the associated buffer in accordance with the new write buffer pointer value.

An example of a system may include a processing resource and a controller including a memory resource storing instructions executable by the processing resource to determine a rate of traffic communication at each of a plurality of ingresses participating in a communication of a packet flow context, determine a rate of traffic communication at each of a plurality of egresses participating in the communication of the packet flow context, determine a target packet admission rate applicable to each of the plurality of ingresses from the rate of traffic communication at each of the plurality of ingresses and the rate of traffic communication at each of the plurality of egresses, and communicate the target packet admission rate to an ingress of the plurality of ingresses.

This application provides a data reassembly method and an apparatus, to reassemble packet fragments in combination with local reassembly and cloud reassembly, so as to obtain a reassembled packet. This improves reassembly efficiency, reduces a packet reassembly delay, and reduces power consumption of an OLT. The method includes: a first OLT receives a plurality of packet fragments of a first packet that are sent by an optical network unit ONU; and if the first OLT determines that an upload condition is met, the first OLT sends the plurality of packet fragments to a cloud reassembly device, so that after receiving the plurality of packet fragments, the cloud reassembly device reassembles the plurality of packet fragments to obtain a second packet.

A packet capture system may copy packets from an interface to a bucket. When the bucket is full of packets, a new bucket for incoming packets may be started, and the full bucket may be indexed. During the indexing, each packet may be sorted in the bucket by flow, and each flow may be indexed. Once indexing is complete, the packets are written to a flow ordered FCAP file and the indexes are written to disk. The flow ordered nature of the FCAP file combined with the indices and their associated search algorithms allow for rapid retrieval of captured flows.

Described is a method for transmitting continuously created data items from an aircraft to a receiver. The data items are of a plurality of data types and each have a different priority. For each data type a live LIFO buffer and a main LIFO buffer are provided. In a regular operation mode continuously created data items are continuously stored in the main buffers. In a transmission operation mode continuously created data items are continuously stored in the live buffers, consecutive data packets are transmitted and for each data packet the data is selected from the buffers, wherein data items stored in live buffers are transmitted before data items stored in main buffers and data items of higher priorities are transmitted before data items of lower priorities. Further, a transmitter and an aircraft are described and claimed.

Packets received by a network switch device from upstream network devices, coupled to respective ones of a plurality of ports of the network switch device, are temporarily stored in an internal memory of the network switch device. In response to detecting a first congestion state in the internal memory, the network switch device transmits a first flow control message via a first subset of ports, without transmitting the flow control message via any port not included in the first subset of ports, to cause upstream network devices in a first subset of upstream network devices to temporarily suspend transmission of packets to the network switch device. The network switch device alternates between causing different subsets of the network devices to temporarily suspend transmission of packets to the network switch device, while continuing to monitor congestion in the internal memory of the network switch device.

This disclosure is directed to embodiments of systems and methods for performing compression of data in a queue. A device intermediary between a client and a server may determine that a length of time to move existing data maintained in a queue from the queue exceeds a predefined threshold. The device may identify, responsive to the determination, a first quantity of the existing data to undergo compression, and a second quantity of the existing data according to a compression ratio of the compression. The device may reserve, according to the second quantity, a first portion of the queue that maintained the first quantity of the existing data, to place compressed data obtained from applying the compression on the first quantity of the existing. The device may place incoming data into the queue beyond the reserved first portion of the queue.

A traffic manager is shared amongst two or more egress blocks of a network device, thereby allowing traffic management resources to be shared between the egress blocks. Schedulers within a traffic manager may generate and queue read instructions for reading buffered portions of data units that are ready to be sent to the egress blocks. The traffic manager may be configured to select a read instruction for a given buffer bank from the read instruction queues based on a scoring mechanism or other selection logic. To avoid sending too much data to an egress block during a given time slot, once a data unit portion has been read from the buffer, it may be temporarily stored in a shallow read data cache. Alternatively, a single, non-bank specific controller may determine all of the read instructions and write operations that should be executed in a given time slot.

Integrated circuits with wireless communications circuitry are provided. The wireless communications circuitry may include an input FIFO, an output FIFO, a processing module interposed between the input and output FIFOs, and dynamic power control circuitry that controls the performance of the processing module. The input and output FIFOs may provide fill level information to the processing module. The dynamic power control circuitry may analyze the current fill level information received from the input and output FIFOs and may increase the operating frequency and/or boost the power supply voltage of the processing module in response to detecting that the input FIFO is filling up faster than the output FIFO or may decrease the operating frequency and/or reduce the power supply voltage of the processing module in response to detecting that the output FIFO is filling up faster than the input FIFO.
