Systems and methods for providing bandwidth congestion control in a private fabric in a high performance computing environment. An exemplary method can provide, at one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, and a plurality of host channel adapters, wherein each of the host channel adapters comprise at least one host channel adapter port, and wherein the plurality of host channel adapters are interconnected via the plurality of switches, and a plurality of end nodes. The method can provide, at a host channel adapter, an end node ingress bandwidth quota associated with an end node attached to the host channel adapter. The method can receive, at the end node of the host channel adapter, ingress bandwidth, the ingress bandwidth exceeding the ingress bandwidth quota of the end node.

A switch or network interface can detect congestion caused by a flow of packets. The switch or network interface can generate a congestion hint packet and send the congestion hint packet directly to a source transmitter of the flow of packets that caused the congestion. The congestion hint packet can include information that the source transmitter can use to determine a remedial action to attempt to alleviate or stop congestion at the switch or network interface. For example, the transmitter can reduce a transmit rate of the flow of packets and/or select another route for the flow of packets. Some or all switches or network interfaces between the source transmitter and a destination endpoint can employ flow differentiation whereby a queue is selected to accommodate for a flow's sensitivity to latency.

Systems and methods of the present disclosure enable mesh network capacity management via network metering using a processor an integrated roofing mesh network node in a mesh network to receive and transmit data packets in the mesh network. Each data packet includes a source address, a destination address, and a payload of data. The processor determines passthrough traffic including a subset of data packets routed between radio nodes of the mesh network through the gateway based on the source address and the destination address of each data packet and an address associated with the gateway. The processor determines a passthrough data capacity based on the payload of each data packet in the subset and determines a metric based on the passthrough data capacity to signify an amount of mesh network bandwidth provided by the integrated roofing mesh network node.

A node (110) of a communication network forwards a first data packet (301) from a server (150) to a client (10). Further, the node detects a congestion affecting the first data packet (301). Further, the node (110) generates at least one second data packet (306) addressed to the server (150). The at least one second data packet (306) indicates the detected congestion and comprises verification information enabling the server (150) to verify that the indicated congestion relates to the first data packet (301).

This application discloses a data processing method and apparatus, and a switching device. The data processing method includes: obtaining a destination address of a data packet received by an input port; determining an available output port based on the destination address; determining a busy degree of the available output port, when there is no non-busy available output port in the available output port, determining a quantity of footprint queues on the available output port, and selecting an available output port with a largest quantity of footprint queues as a target output port; determining a busy degree of a queue on the target output port, and when there is no non-busy queue on the target output port, selecting a footprint queue on the target output port as a target output queue. In the foregoing manners, a network resource is properly used, and network blocking can be effectively alleviated.
