Abstract

The invention discloses a method for balancing a network flow load, which balances the load of the connection communication of packet handler threads in network equipment. The method comprises the following steps of: executing a plurality of packet handler threads and designing a queue to each thread to store the received packets, wherein the threads read the packets from the queue and handle the packets; and judging whether the number of the packets in the queue meets a threshold value of a flow or not, wherein when the number of the packets in a certain queue meets the working threshold value, the network equipment dispatches the new packets to other queues under the principle that the integrity of the connection communication is not affected. The method not only can keep the integrity of the connection communication but also ensure the accordant load of the packet handler threads.

Description

technical field [0001] A network data packet processing method, in particular to a network traffic load balancing processing method. Background technique [0002] With the maturity of the Internet, the transmission technology of the network is also updated day by day. Therefore, many network devices have added load balancing functions. The load balancing of network transmission is mainly aimed at network devices receiving large-flow data packets, and the network devices will assign corresponding queues to store data packets and process them through corresponding thread processes. In order to avoid the limitation of a single processing thread, the data packet processing task is completed simultaneously through multiple threads; and the correctness of data packet processing is guaranteed by the function of ensuring the completion of connection communication. [0003] However, the known load balancing still has its disadvantages. Please refer to figure 1 As shown in , it is...
