Technologies for scalable packet reception and transmission include a network device. The network device is to establish a ring that is defined as a circular buffer and includes a plurality of slots to store entries representative of packets. The network device is also to generate and assign receive descriptors to the slots in the ring. Each receive descriptor includes a pointer to a corresponding memory buffer to store packet data. The network device is further to determine whether the NIC has received one or more packets and copy, with direct memory access (DMA) and in response to a determination that the NIC has received one or more packets, packet data of the received one or more packets from the NIC to the memory buffers associated with the receive descriptors assigned to the slots in the ring.

The invention relates to a communication node for a data networks for receiving messages from a physical interface having transmitting and receiving means, by way of which physical interface the communication node is connectable to a communication line of a data network, comprising: a communication module for receiving a message and for creating a corresponding message object referencing message data of the received message and metadata, the communication module being configured to store the message object in a memory and to create a message event upon creating the message object, the message event containing or being associated with a reference to the message object; a tagging and filtering unit configured to retrieve the message object referenced by its message event upon receiving the message event and, if a predefined filter criteria applied to the message object is met, configured to derive a tag and to update the message object in the memory with the determined tag to be a tagged message object; and a processing unit being configured to retrieve the tagged message object from the memory and to process the tagged message object based on the tag.

A method for data transmission may be implemented on an electronic device having one or more processors. The one or more processors may include a master queue including a master queue head and a plurality of primary ports that are connected to each other using a serial link. The method may include operating the master queue head to obtain a message. The method may also include operating the master queue head to segment the message into a plurality of segments. The method may also include operating the master queue head to transmit the plurality of segments to a first primary port of the plurality of primary ports in the master queue. The method may also include operating the first primary port to transmit the plurality of segments to a second primary port of the plurality of primary ports in the master queue.

Provided are method and apparatus for processing data packets, a device, and a storage medium that relate to the field of communications. The method includes: receiving multiple data packets of an identical service transmitted in multiple frequency bands, where each of the data packets carries arrangement indication information; and sorting the data packets based on the arrangement indication information carried in each of the data packets.

A method includes obtaining a first plurality of encrypted traffic flows traversing a communication network, performing a first classification, wherein a result of the first classification identifies a traffic type associated with each encrypted traffic flow of the first plurality of encrypted traffic flows, and wherein the first classification is based on a traffic pattern of the each encrypted traffic flow, performing a second classification, wherein a result of the second classification identifies a traffic type associated with each server name indication from which the first plurality of encrypted traffic flows is associated, and wherein the second classification is based on the result of the first classification, and performing a third classification identifying a traffic type associated with each encrypted traffic flow of the first plurality of encrypted traffic flows, wherein the third classification is based on a combination of the results of the first classification and the second classification.

A data accessing method of a switch for transmitting data packets between a first source node and a first target node and between a second source node and a second target node includes: transmitting a data packet to the switch via at least one of the first communication link and the third communication link and configuring the control unit to store information contained in the data packet into the storage unit; and retrieving the information contained in the data packet from the storage unit via at least one of the second communication link and the fourth communication link. The first source node, the second source node, the first target node and the second target node share the same storage blocks.

The disclosure describes a data enqueuing method. The method may include: receiving a to-be-enqueued data packet, dividing the data packet into several slices to obtain slice information of the slices, and marking a tail slice of the data packet with a tail slice identifier; enqueuing corresponding slice information according to an order of the slices in the data packet, and in a process of enqueuing the corresponding slice information, if a slice is marked with the tail slice identifier, determining that the slice is the tail slice of the data packet, and generating a first-type node; and determining whether a target queue is empty, and if the target queue is empty, writing slice information of the tail slice into the target queue, and updating a head pointer of a queue head list according to the first-type node.

A first memory device stores (i) a head part of a FIFO queue structured as a linked list (LL) of LL elements arranged in an order in which the LL elements were added to the FIFO queue and (ii) a tail part of the FIFO queue. A second memory device stores a middle part of the FIFO queue, the middle part comprising a LL elements following, in an order, the head part and preceding, in the order, the tail part. A queue controller retrieves LL elements in the head part from the first memory device, moves LL elements in the middle part from the second memory device to the head part in the first memory device prior to the head part becoming empty, and updates LL parameters corresponding to the moved LL elements to indicate storage of the moved LL elements changing from the second memory device to the first memory device.

Disclosed is method for operating a protocol translator between an upstream device and a downstream device including receiving, at the protocol translator from the upstream device, a first plurality of packets according to a first protocol, extracting a payload from each of the first plurality of packets according to the first protocol, constructing a message from the extracted payloads, slicing the message into a second plurality of packets according to a second protocol, storing the second plurality of packets in a retransmit queue, sending the second plurality of packets to the downstream device, receiving an acknowledgement from the downstream device, and removing from the retransmit queue, one or more packets identified by the acknowledgement.
