20210266250 · 2021-08-26 ·

A system and method is provided for timely and uniform real-time data packet transmission by a computing device. The system can include a shared packet memory buffer for storing data packets generated by a user application and a shared schedule memory buffer for storing packet identifiers and corresponding time slots for the data packets. Moreover, a kernel module is provided that operates in the kernel mode of the operating system directly above the network interface controller and can continuously poll the shared scheduled memory to access packet identifiers at corresponding time slots. Based on the packet identifiers in each time slot, the kernel module can pull the data packet having the packet identifier directly from the ring buffer and send each packet to the network interface controller for transmission as part of a media stream over a network to a media consuming device.

Method for transmitting MAC PDUs and related product

Embodiments of the present application disclose a data transmission method and a related product, including: a receiving end receives a data packet from a transmitting end, the data packet including a medium access control layer (MAC) protocol data unit (PDU), the MAC PDU including multiple MAC subPDUs, and at least one MAC subPDU of the multiple MAC subPDUs including a MAC sub-header; where the MAC sub-header includes a first information field, and the first information field is configured to indicate whether the MAC sub-header includes a length indication L field. The embodiments of the present application, by introducing the first information field in an existing MAC sub-header format, where the first information field can be used to dynamically indicate whether a current MAC subPDU includes an L field, are beneficial to the improvement in flexibility and efficiency of data processing at the receiving end.

CONTROLLER-TO-CONTROLLER INTERFACE FOR MULTI-LAYER NETWORK ABSTRACTION

A controller at an IP (e.g., client) layer in a multi-layer network can request a network topology map from another controller at an optical (e.g., server) layer in the multi-layer network. The controller at the optical layer of the network can use a layer mapping function and common attributes between the formats used to describe the network topology map at the two layers to generate a common layer abstraction model representing the network topology map stored at the controller at the optical layer of the network. A controller-to-controller interface can translate and/or send the common layer abstraction model to the controller at the IP layer for processing data on the network.

Aspects described herein relate to POLL timer enhancement in fifth generation new radio (5G NR). In an example, the aspects may include determining whether a count of packet data unit (PDU) without POLL associated with a current PDU sequence satisfies a threshold for maximum PDUs without POLL; determining whether a total transmission queue memory exceeds an uplink transmission queue memory threshold; generating a POLL bit based on a determination that the PDU without POLL count associated with the current PDU without POLL in-sequence satisfies the threshold for maximum PDUs without POLL and the total transmission queue memory exceeds the threshold for uplink transmission queue memory; and transmitting, to a network entity, the current PDU with the POLL bit.

Active link during LAN interface reset

Methods and apparatus for supporting active link status during LAN interface reset and reconfigurations. Under one aspect, during normal operations traffic is transmitted over an Ethernet link coupling a first link partner to a second link partner. In response to a network interface re-configuration event, transmission of traffic over the Ethernet link is paused while keeping the Physical layer (PHY) of the Ethernet link active. The configuration of the first link partner is updated while the transmission of traffic is paused and the PHY of the Ethernet link is active. Upon completion of the configuration update, the link partners resume transmission of traffic over the Ethernet link. Additional schemes are provided that support re-configuration of network interfaces that support link and per priority flow control. According to another aspect, separate power domains are used for the PHY and the MAC circuitry, enabling the MAC circuitry to be reset via a power cycle while maintaining power to the PHY circuitry.
