Embodiment Construction

[0026] The traffic sharing method based on the combined application of the isolation device and the isolation gateway of the present invention is aimed at the application scenario where multiple isolation devices are connected in parallel to form a cluster. When the network traffic passes through the isolation gateway to each isolation device, the resource utilization efficiency of the isolation device For low-level problems, the sharing method of selecting links for data traffic distribution according to the weight value is adopted. According to the change of data traffic and link status, the link weight value is dynamically adjusted for network traffic sharing, which improves the efficiency of traffic sharing.

[0027] The specific implementation of the traffic sharing method based on the combined application of the isolation device and the isolation gateway of the present invention will be described in detail below with reference to the accompanying drawings.

Abstract

The invention provides a flow sharing method based on combine application of an isolating device and an isolating gateway. The flow sharing method based on combine application of the isolating device and the isolating gateway includes steps that load resources in link of each isolating devices in networking is ordered through the isolation gateway, and weighted values of each link is arranged according to orders; when data messages pass through the isolation gateway, a conversation excel item is established on the isolation gateway according to basic information of the data messages, the link with the maximal weighted value at present is selected, and a conversation connection is founded on the link according to the conversation item, then the data messages are transmitted; when the link is selected and used for transmitting the data messages, the weighted value of the link is reduced 1; when one data message is finished being transmitted, the corresponding conversation connection is broken off, and the conversation item is removed, and then the weighted value of the link is added 1. According to the flow sharing method based on combine application of the isolating device and the isolating gateway, bandwidths capable of being in efficient use of the isolating devices in parallel are ensured, and the network flows are shared on different isolating devices more reasonably.

Description

technical field [0001] The invention relates to load balancing technology, in particular to a traffic sharing method based on the combined application of an isolation device and an isolation gateway. Background technique [0002] Isolation device: that is, the safety isolation device dedicated to the electric power network, including two types of forward and reverse. It is a safety protection device between the dispatching data network and the public information network, which is composed of special hardware with multiple control functions. , the forward type is used for one-way data transfer from security zone I / II to security zone III, and the reverse type is used for one-way data transmission from security zone III to security zone IV. [0003] Isolation gateway: A gateway that isolates two connected networks based on unidirectional forwarding, including but not limited to routers, switches, or servers. [0004] Load balancing: According to the pre-configured load balanc...
