A method and system for multi-packet shared rqe in ud mode

Abstract

The application discloses a method and system for multi-packet shared RQE under a UD mode, wherein the method comprises the following steps: configuring a shared queue pair context Shared QP Context for each queue pair QP; receiving a datagram, searching for a queue pair context QP Context and the shared queue pair context Shared QP Context according to information in the datagram, and judging whether there is a currently used RQE; if there is, judging whether the datagram is allowed to share the currently used RQE; if allowed to share, writing a payload of the datagram into a remaining position of a memory buffer pointed to by the currently used RQE, and updating the shared queue pair context Shared QP Context; if not allowed to share, ending the currently used RQE, generating a corresponding shared completion queue element Shared CQE, and writing the payload of the datagram into a memory buffer pointed to by a new RQE, and initializing the shared queue pair context Shared QP Context; wherein the shared completion queue element Shared CQE is used for recording information of all the datagrams processed by the ended RQE.
