Load balancing method and system

Abstract

The invention discloses a load balancing system and method. The load balancing system comprises at least two gateways which are communicated with each other, wherein each gateway comprises a memory and a controller; an instruction is stored in the memory, and the instruction executes the following steps under the control of the controller: one gateway is determined as a control node; the control node determines the information of intelligent terminals connected with the intelligent terminals on all gateways, and the information of the intelligent terminals comprises the types of the intelligent terminals, media access control (MAC) interfaces and interface numbers; the control node allocates all intelligent terminals needing to be processed according to the load capacity of the gateway; and the gateway acquires and processes the intelligent terminal data which is connected to other gateways and needs to be processed through link layer unvarnished transmission. Compared with the prior art, on the basis of an original network structure, the load balancing system concentrates and redistributes operation tasks of the loads on the gateways, guarantees that surplus hardware resources ofthe gateways can be distributed to other intelligent terminals in time, and meanwhile does not need to add extra physical lines.

Description

technical field [0001] The invention relates to the field of computer network resource scheduling, in particular to a load balancing method and system. Background technique [0002] The development of computer technology has made industrial production more and more informatized. Some information and data that are traditionally difficult to obtain in real time can be obtained and processed in real time through various smart terminals. The typical application environment is to monitor production and monitor environmental safety in factories and mines. For the set sensor network, this type of application environment usually includes core nodes, sub-nodes and intermediate nodes between the two. Sensors for monitoring specific parameters such as temperature, humidity, pressure, and electromagnetics are used as sub-nodes of this type of network. At the same time, there are network devices as core nodes and intermediate nodes that aggregate data from sensor networks, in such applic...

Problems solved by technology

The more sensors there are as sub-nodes, the higher the complexity of the system. In addition, unlike common IP networks and program-controlled networks, the sub-nodes of such networks usually do not have strong computing performance and need to be used as the middle of the gateway. Nodes and core nodes process data, rather than just routing and forwarding data, so the peak computing load on the local network poses a great challenge to the data processing capability of the gateway, thus affecting the robustness of the entire system

[0003] Conventional Internet Protocol Address (IP) networks and program-controlled networks usually use core network load balancing to disperse the throughput capacity of the network, so the balance cannot be completed between intermediate nodes and sub-nodes, and the computing tasks of sub-nodes cannot be effectively distributed.

Moreover, the common load balancing method of using multiple links to connect to the same node at the core layer is not suitable for child nodes.
