Abstract: Aspects of the disclosure are directed to a packet cache eviction engine for reliable transport protocols of a network. The packet cache eviction engine can manage on-chip cache occupancy by evicting lower priority packets to off-chip memory and ensuring that higher priority packets are kept on-chip to achieve higher performance and lower latency in processing packets in the network.

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: Aspects of the disclosure are directed to a high performance connection scheduler for reliable transport protocols in data center networking. The connection scheduler can handle enqueue events, dequeue events, and update events. The connection scheduler can include a connection queue, scheduling queue, and quality of service arbiter to support scheduling a large number of connections at a high rate.
