Problems solved by technology

[0004] Therefore, the existing data shunting method has the following disadvantages: multiple threads share the buffer queue of the same process, which will cause a large amount of mutual exclusion and synchronization overhead between threads and cache failure between cores, resulting in insufficient processing capacity of multi-core processors. to play

Abstract

The invention relates to a data splitting method and a splitter. The data splitting method includes: the splitter analyzes the received data packet to determine the transport layer communication protocol to which the data packet belongs; the splitter obtains from the data packet corresponding to the determined transport layer communication protocol The identification information of the data flow to which the data packet belongs; the splitter obtains from the memory the split corresponding to the transport layer communication protocol to which the data packet belongs according to the corresponding relationship between the transport layer communication protocol and the split table table; the splitter determines the thread corresponding to the data stream to which the data packet belongs according to the identification information of the data stream in the split table corresponding to the transport layer communication protocol to which the data packet belongs and the thread; the split The controller sends the data packet to the buffer queue of the thread corresponding to the data flow, so that the thread corresponding to the data flow obtains the data packet from the buffer queue.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a data splitting method and a splitter. Background technique [0002] Today, processors have entered the multi-core era. Under the multi-core architecture, multi-threads are often deployed in multiple cores to achieve parallel processing. Then, it is necessary to send data packets to different threads by shunting to make multiple cores Implement parallel processing. [0003] In the existing data distribution method, the distribution granularity is process, that is, the data packet is sent to the buffer queue of the process corresponding to the data packet. Threads in this process obtain data packets from the buffer queue of this process, and the connection information of this data packet may be shared by other threads. If it is shared, when the thread accesses the connection information corresponding to the data packet, the mutual exclusion and synchronization mechanism betwe...
