Balanced segmentation strategy of user mode protocol stack for external load process

Abstract

The invention discloses a balanced segmentation strategy of a user mode protocol stack for an external load process, relates to the field of network processing, and discloses a strategy for balancingand segmenting a load application process based on a multi-thread user mode protocol stack so as to reduce a load competition relationship between load protocol stack threads. The implementation of the strategy is divided into two steps: step A, distributing load processes to different service threads in a balanced manner according to an initial network flow; and B, enabling the service thread toobtain a private load process table based on the load process distribution result in the first step, and enabling the service thread to select a load process from the private load process table for asubsequently received network flow. By using the balanced partitioning strategy, the resource competition expenditure introduced by sharing the load process can be removed, and meanwhile, the number of load processes of a single service thread is reduced, so that the cache miss times caused by loading excessive load data are reduced.

Description

technical field [0001] The invention relates to the field of computer network service stacks, in particular to a strategy for balancing and splitting external load processes by user state protocol stacks. Background technique [0002] In the past two decades, the processing rate of network input and output of the kernel network protocol stack has been difficult to achieve the packet receiving rate of network card hardware devices with rapidly improved performance due to memory copy overhead, context switching overhead, kernel data processing, and queue delay. Therefore, many studies have directly implemented the data plane for processing network packets in the user space, eliminating the upper-write switching overhead and kernel data processing and queue delays by bypassing the kernel, and reducing the development difficulty of the network protocol stack. [0003] The processing model of the user mode network protocol stack can be divided into 1) application and protocol sta...
