Problems solved by technology

[0005] There are multiple network cards and multiple CPUs in a multi-core CPU system. Usually, one network card corresponds to only one CPU. At this time, the smallest load balancing unit is the network card. When the traffic of the network card is very large, the corresponding CPU will be very busy, so It may cause network packet loss, which will greatly affect the speed of accessing the network

Abstract

The invention relates to a multi-core CPU load balancing method based on ring and a system thereof. The method comprises the following steps: detecting the load balancing conditions of all CPUs in the multi-core CPU in real time and judging whether the multi-core CPU is balanced; evaluating the loading conditions of all rings under the condition that of the multi-core CPU is not balanced; and adjusting binding relationship among the ring and the CPUs by using the ring as a unit. The method uses the ring as a least unit to adjust the CPU load degree, the division of the flow rate of a network card is finer, and further the multi-core CPU load is more balanced. The method and the system thereof of the invention can be widely applied in the multi-core CPU.

Description

technical field [0001] The present invention relates to a multi-core CPU (Central Processing Unit, central processing unit), and in particular to network load balancing of a multi-core CPU. Background technique [0002] The current network has become very popular, and the rapid development of the Internet has made network access more and more frequent. Therefore, users have higher and higher requirements for network bandwidth and network access speed. Network cards in network equipment have developed from 10M network cards, 100M network cards to Gigabit network cards with the user's requirements for network access speed. [0003] With the increase in the business volume of each core part of the existing network and the rapid growth of access and data traffic, the requirements for data processing capabilities and computing intensity have also been greatly enhanced, making it impossible for a single server device to bear. In this case, if the existing equipment is discarded t...
