摘要： A traffic shaper in a packet communication apparatus receives packets and immediately calculates a departure time for each received packet, using designated bandwidth allocation parameters. The packets are stored in a packet memory according to their calculated departure times. When each departure time arrives, the packets that have been stored for that departure time are transferred to an output queue. Packets are output in sequential order from the output queue.

摘要： A packet processing method and device are provided, to save CPU resources consumed by parsing a packet. The method includes: parsing, by an intelligent network interface card, a received first packet to obtain an identifier of the first packet; updating, by the intelligent network interface card, a control field of a first memory buffer based on the identifier of the first packet; storing, by the intelligent network interface card, a payload of the first packet or a packet header and a payload of the first packet into the first address space through DMA based on an aggregation position of the first packet; aggregating, by a host, the first address information and at least one piece of second address information based on an updated control field in the first mbuf; and reading, by a virtual machine, address information, to obtain data in an address space indicated by the address information.

摘要： A 5G communication system or pre-5G communication system for supporting a higher data rate than that of a beyond 4G communication system such as an LTE is provided. A method by an apparatus for controlling buffers in a wireless communication system comprises storing information related to a packet in at least one of a first buffer or a second buffer, transmitting data generated based on the packet, and, when an acknowledgement signal is received for the data, discarding the information.

摘要： Systems and methods for efficiently storing a distributed ledger of records. In an exemplary aspect, a method may include generating a record comprising a payload and a header, wherein the payload stores a state of a data object associated with a distributed ledger and the header stores a reference to state information in the payload. The method may further comprise including the record in a trunk filament comprising a first plurality of records indicative of historic states of the data object, wherein the trunk filament is part of a first lifeline. The method may include identifying a jet of the distributed ledger, wherein the jet is a logical structure storing a second lifeline with a second plurality of records. In response to determining that the first plurality of records is related to the second plurality of records, the method may include storing the first lifeline in the jet.

摘要： A network interface device is connected to a host computer by having a memory controller, and a scatter-gather offload engine linked to the memory controller. The network interface device prepares a descriptor including a plurality of specified memory locations in the host computer, incorporates the descriptor in exactly one upload packet, transmits the upload packet to the scatter-gather offload engine via the uplink, invokes the scatter-gather offload engine to perform memory access operations cooperatively with the memory controller at the specified memory locations of the descriptor, and accepts results of the memory access operations.

摘要： Techniques for improved handling of queues of data units are described, such as queues of buffered data units of differing types and/or sources within a switch or other network device. When the size of a queue surpasses the state entry threshold for a certain state, the queue is said to be in the certain state. While in the certain state, data units assigned to the queue may be handled differently in some respect, such as being marked or being dropped without further processing. The queue remains in this certain state until its size falls below the state release threshold for the state. The state release threshold is adjusted over time in, for example, a random or pseudo-random manner. Among other aspects, in some embodiments, this adjustment of the state release threshold addresses fairness issues that may arise with respect to the treatment of different types or sources of data units.

摘要： Technologies for low-latency data streaming include a computing device having a processor that includes a producer and a consumer. The producer generates a data item, and in a local buffer producer mode adds the data item to a local buffer, and in a remote buffer producer mode adds the data item to a remote buffer. When the local buffer is full, the producer switches to the remote buffer producer mode, and when the remote buffer is below a predetermined low threshold, the producer switches to the local buffer producer mode. The consumer reads the data item from the local buffer while operating in a local buffer consumer mode and reads the data item from the remote buffer while operating in a remote buffer consumer mode. When the local buffer is above a predetermined high threshold, the consumer may switch to a catch-up operating mode. Other embodiments are described and claimed.

摘要： Technologies for dynamic multi-core packet processing distribution include a compute device having a distributor core, a direct memory access (DMA) engine, and multiple worker cores. The distributor core writes work data to a distribution buffer. The work data is associated with a packet processing operation. The distributor core may perform a work distribution operation to generate the work data. The work data may be written to a private cache of the distributor core. The distributor core programs the DMA engine to copy the work data from the distribution buffer to a shadow buffer. The DMA engine may copy the work data from one cache line of a shared cache to another cache line of the shared cache. The worker cores access the work data in the shadow buffer. The worker cores may perform the packet processing operation with the work data. Other embodiments are described and claimed.
