Abstract
Disclosed herein are methods and apparatus for accelerating RoCE packet sequence transmission and reducing processing latency in received RoCE packets. Under the disclosed method, the RoCE protocol stack and RDMA verbs are implemented partially in the host software and partially in the adapter hardware, thereby providing a better balance between simplifying the adapter configuration and maximizing the host processing efficiency. Particularly, the adapter implemented with partial RoCE offload is able to perform a few major functionalities under the RoCE protocol, such as offloading a complete RoCE packet sequence for transmission, building individual packets out of the RoCE packet sequence and performing Invariant CRC calculation, insertion, validation and removal thereof.
