A digital data communications network that supports efficient, scalable routing of data and use of network resources by combining a recursive division of the network into hierarchical sub-networks with repeating parameterized general purpose link communication protocols and an addressing methodology that reflects the physical structure of the underlying network hardware. The sub-division of the network enhances security by reducing the amount of the network visible to an attack and by insulating the network hardware itself from attack. The fixed bandwidth range at each sub-network level allows quality of service to be assured and controlled. The routing of data is aided by a topological addressing scheme that allows data packets to be forwarded towards their destination based on only local knowledge of the network structure, with automatic support for mobility and multicasting. The repeating structures in the network greatly simplify network management and reduce the effort to engineer new network capabilities.

Enabling a protocol for efficiently and reliably using the NVME protocol over a network, referred to as NVME over Network, or NVMEoN, may include an NVMEoN exchange layer for handling exchanges between initiating and target nodes on a network, a burst transmission protocol that provides guaranteed delivery without duplicate retransmission, and an exchange status block approach to manage state information about exchanges.

This application provides a data transmission method and apparatus. The method includes: determining a first sending rate based on a network performance objective of first data and a network status of a first transmission control protocol (TCP) connection of a transport layer protocol, where the first TCP connection is used to send the first data; and sending the first data based on the first sending rate. In this way, network congestion control is more flexible, and TCP-based data transmission efficiency is improved.

Method, apparatuses, and storage mediums are provided for establishing an RRC connection in the technical field of communications. The method may include: receiving a designated signaling sent by a first base station, the designated signaling carrying system configuration information of a second base station; and establishing an RRC connection with the second base station, based on the system configuration information of the second base station.

A first component of a network device may provide an offload request to a second component of the network device to offload a data flow from the first component. The offload request may direct the second component to provide the data flow towards a destination device and bypass the first component. The first component may receive a beacon from the second component. The beacon may identify information regarding one or more data flows offloaded from the first component. The first component may process the one or more data flows based on the information regarding the one or more data flows included in the beacon and without receiving the one or more data flows.

A method and apparatus of a device that determines a cause and effect of congestion in this device is described. In an exemplary embodiment, the device measures a queue group occupancy of a queue group for a port in the device, where the queue group stores a plurality of packets to be communicated through that port. In addition, the device determines if the measurement indicates a potential congestion of the queue group, where the congestion prevents a packet from being communicated within a time period. If potential congestion exists on that queue group, the device further gathers information regarding packets to be transmitted through that port. For example, the device can gather statistics packets that are stored in the queue group and/or new enqueue packets.
