Abstract
Methods, apparatus, and systems for implementing a semi-flexible Receive Segment Coalescing (RSC) control path. Logic for evaluating packet coalescing open flow criteria and close flow criteria are implemented in hardware on a network device that receives packets from one or more networks. packet coalescing open profiles and packet coalescing close profiles are also stored on the network device, wherein each packet coalescing open profile defines a set of packet coalescing open flow criteria to be applied for that packet coalescing open profile and each packet coalescing close profile defines a set of packet coalescing close flow criteria to be applied for that packet coalescing open profile. packet coalescing open flow and close flow profiles are then assigned to packet coalescing-enabled receive queues on the network device and corresponding open and flow criteria are used to perform packet coalescing-related processing of packets in the receive queues. The scheme supports hardware-based packet coalescing packet processing while providing flexibility in meeting the requirements of different operating systems and future usage models on a single network device.
