Methods, apparatus, systems, and articles of manufacture are disclosed for dynamic load balancing for multi-core computing environments. An example apparatus includes a first and a plurality of second cores of a processor, and circuitry in a die of the processor separate from the first and the second cores, the circuitry to enqueue identifiers in one or more queues in the circuitry associated with respective ones of data packets of a packet flow, allocate one or more of the second cores to dequeue first ones of the identifiers in response to a throughput parameter of the first core not satisfying a throughput threshold to cause the one or more of the second cores to execute one or more operations on first ones of the data packets, and provide the first ones to one or more data consumers to distribute the first data packets.

The present disclosure generally relates to data transfer device for receiving data from a host device and method therefor. The device comprise a plurality of input ports configured to receive input data comprising of a plurality of bytes, an output port configured to provide an output data byte and a plurality of buffer units, each buffer unit coupled to an input port of the plurality of input ports. Each of the plurality of buffer units receives a portion of the input data, wherein an enable bit is associated with the portion of data and each of the buffer devices provides the received portion of data as an output, if the enable bit indicates that the portion of data is not a garbage data.

A stateful service processing method and apparatus are provided, related to the field of communication technologies. The method includes: preprocessing a received first packet to obtain a coalescing message of the first packet; coalescing the first packet into a first queue based on the coalescing message of the first packet, where the first queue is used to coalesce packets of a first connection to which the first packet belongs, and the first connection is a connection in which a stateful service is located; when a preset condition is met, processing, based on a context of the first connection, a plurality of packets coalesced in the first queue to obtain a second packet, where the context of the first connection is an updated context obtained after a previous second packet of the first connection is obtained; and transmitting the second packet to the host.

One aspect of the instant application provides a system and method for generating internal traffic for a switch. During operation, the system configures a replication list comprising a plurality of replication entries, with a respective replication entry corresponding to a destination port on the switch. The system generates a seed packet to be replicated for each replication entry in the replication list, with a destination address of a respective replicated packet corresponding to a replication entry. All replicated packets are associated with a virtual local-area network (VLAN) reserved for the internal traffic. The system then forwards the replicated packets along with external packets received by the switch to corresponding destination ports on the switch.

A network device, associated with peer network devices, may receive policy information for a protocol; and compute a first update message based on information regarding a route associated with the policy information. The network device may determine that an upper utilization threshold for one or more of peer queues, associated with the peer network devices, is not satisfied; and write the first update message to the peer queues based on determining that the upper utilization threshold is not satisfied. The network device may compute a second update message based on the information regarding the route; determine that the upper utilization threshold for one or more of the peer queues is satisfied; and pause writing the second update message to the peer queues based on the upper utilization threshold being satisfied. The network device may permit the peer network devices to obtain data from corresponding ones of the peer queues.

A communication system in which DRA control is aided by RL. An example embodiment may control one or more buffer queues populated by downstream and/or upstream data streams. The egress rates of the buffer queues can be dynamically controlled using an RL technique, according to which a learning agent can adaptively change the state-to-action mapping function of the DRA controller while circumventing the RL exploration phase and relying on extrapolation of the already taken actions instead. This feature may result in at least two benefits: (i) cancellation of a performance penalty typically associated with RL exploration; and (ii) faster learning of the environment, as the learning agent can determine the performance metrics of many actions per state in a single occurrence of the state. In an example embodiment, the communication system may be a DSL system, a PON system, or a wireless communication system.

A system for facilitating efficient command management in a network interface controller (NIC) is provided. During operation, the system can determine, at the NIC, a trigger condition and a location in a command queue for a set of commands corresponding to the trigger condition. The command queue can be external to the NIC. The location can correspond to an end of the set of commands in the command queue. The system can then determine, at the NIC, whether the trigger condition has been satisfied. If the trigger condition is satisfied, the system can fetch a respective command of the set of commands from the command queue and issuing the command from the NIC until the location is reached, thereby bypassing locally storing the set of commands prior to the trigger condition being satisfied.

A communication system and an operation method thereof are provided. The transmitting device transmits the current data unit and the transmitted data verification information to the receiving device through the communication interface, and records the current data unit in an FIFO buffer. The receiving device counts the received data identification value by itself based on the current data unit received from the communication interface. The receiving device uses the received data identification value and the transmitted data verification information to check whether the current data unit received from the communication interface has errors. When the current data unit is in error, the receiving device returns an error flag to the transmitting device so that the transmitting device suspends the transmission of the new data unit, and transmits the buffered data unit recorded in the FIFO buffer to the receiving device through the communication interface.

Technologies for adaptive network packet egress scheduling include a switch configured to configure an eligibility table for a plurality of ports of the switch, wherein the eligibility table includes a plurality of rounds. The switch is further configured to retrieve an eligible mask corresponding to a round of a plurality of rounds of the eligibility table presently being scheduled and determine a ready mask that indicates a ready status of each port. The switch is further configured to determine, for each port, whether the eligible status and the ready status indicate that port is both eligible and ready, and schedule, in response to a determination that at least one port has been determined to be both eligible and ready, each of the at least one port that has been determined to be both eligible and ready. Additional embodiments are described herein.

A network interface module for coupling a host device to a switched network as a network node is described. The network interface module comprises a single half-duplex port for communicatively coupling to a shared bus of the switched network, at least one frame queue sized to store one multicast read frame received via the shared bus, and logic circuitry. The logic circuitry is configured to decode a read command for the interface module included in a payload of the multicast read frame that includes multiple read commands for other network nodes of the switched network, and transmit a response frame including read data on the shared bus when detecting the shared bus is available for transmitting.
