Abstract: A flow rate control method for solicited data communications includes receiving, at a first node of a communications network, a request-to-send (RTS) signal from a second node of the communications network, the RTS signal indicating a size of a solicited data transmission of the second node, determining, by the first node, whether a rate-limiting counter is above zero, wherein the rate-limiting counter is programmed to increase at a programmed rate and in response to the rate-limiting counter being above zero, scheduling, by the first node, a clear-to-send (CTS) signal to be sent from the first node to the second node over the communications network, and subtracting, by the first node, a value corresponding to the size of the solicited data transmission of the second node from the rate-limiting counter.

Abstract: Aspects of the disclosure are directed to supporting time synchronization across a datacenter network with greater accuracy. The time synchronization includes both software based and hardware based time synchronization mechanisms to provide more precise time synchronization across various nodes in the datacenter network. The software based mechanism can provide the initial coarse time synchronization while the hardware based mechanism can provide the subsequent finer time synchronization.

Abstract: A custom processor core is provided, wherein the custom processor core may be used for congestion control in reliable transport protocols. The hardware architecture of the custom processor core allows for custom instructions, special register sets, and datapath enhancements for accelerating congestion control algorithms to achieve higher performance.
