The disclosure may provide methods, systems and apparatus related to a switch-assisted transport layer using network-aware rate adjustment. According to an aspect, a method by a network device may be provided. The method includes receiving one or more data packets corresponding to one or more flows to be forwarded through an egress port of the network device. Each data packet may indicate a flow demand per time period T for a corresponding flow of the one or more flows. The method further includes determining a demand value for the egress port based on the indicated flow demand. The method further includes sending the one or more data packets through the egress port. Each data packet sent may indicate a value for an aggregated demand of the corresponding flow, The value for the aggregated demand may be based on the determined demand value.

System and methods for network-aware rate adjustment

There is provided a method and apparatus to generate temporal congestion signals. The method is used by a device and includes receiving a packet which includes a request for network state information and generating one or more temporal congestion signals. The method also including adding the temporal congestion signals to the packet and transmitting the packet including the temporal congestion signals. The temporal congestion signals can include one or more of a line busyness signal, which measures the duration of a busy period of the device, and a line idleness signal, which measures the duration of an idle period of the device.

Hardware accelerated temporal congestion signals

There is provided methods and devices for network management. A method includes receiving at least one data flow, transmitting in-band management packet periodically for each of the at least one data flow, receiving in-band acknowledgement packets for each of the at least one data flow, and producing network management data based on received in-band acknowledgement packets. A device includes a processor, and a non-transient computer readable memory having stored thereon machine executable instructions which when executed by the processor configure the device to execute the methods disclosed herein. A system includes a source node, a receiver and a data-plane device, the system configured to execute the methods disclosed herein.
