Problems solved by technology

[0005] (1) In the prior art, descriptors are stored in fixed-size FIFOs. Since different SQ queues have different degrees of activity, in order to meet the requirements of descriptor storage in the design, a large capacity will be allocated to each descriptor storage resources, which will cause a lot of waste of storage resources and affect the efficiency of storage
[0006] (2) The existing technology does not fully consider the activity of each session, and stores each descriptor uniformly, which lacks flexibility
[0007] (3) Occupying too many storage resources will lead to lower processing efficiency of the entire offload engine network card

Abstract

The invention belongs to the technical field of data transmission network, and discloses an optimization method, system and terminal for pre-reading descriptors in an offloading engine network card, and performs pre-reading processing on descriptors in a DMA receiving module of a TCP / IP offloading engine; After pre-reading is successful, update the descriptor information in the queue, and judge whether the number of descriptors meets the maximum and minimum storage thresholds; if so, continue to send the SQ pre-reading request to the DMA receiving module. The invention solves the problem of occupying too many cache resources when storing descriptors in the existing TCP / IP unloading engine network card. The present invention can realize the dynamic storage of descriptors in the buffer area, reduce the waste of storage resources, and the software can dynamically manage the maximum and minimum thresholds of each queue storage space according to the activity of different sessions, and then flexibly adjust the pre-reading of each queue The number of descriptors makes the prefetching of SQ descriptors more efficient and balanced.

Description

technical field [0001] The invention belongs to the technical field of data transmission networks, and in particular relates to an optimization method, system and terminal for pre-reading descriptors in a network card of an offload engine. Background technique [0002] At present, when Ethernet is widely used today, using a common network card to process TCP / IP data packets will increase the processing burden of the server. Therefore, in order to limit the data processing volume of the CPU in the network link, the TCP / IP offload engine technology offloads the work of the TCP / IP stack to the adapter or system hardware, and implements TCP / IP through network processors and firmware and application-specific integrated circuits. accelerate. The TCP / IP offload engine technology enables the application system to make full use of the network capacity, which improves the network performance and reduces the cost of the network. It has gradually shown great potential in today's Ethern...
