Dynamic operating threshold based efficient traffic control method

Abstract

The invention discloses a dynamic operating threshold based efficient traffic control method. The dynamic operating threshold based efficient traffic control method specifically comprises the steps of determining to accept or refuse a connection request by a local communication management agent based on local information of each switch; when one connection request is accepted, modifying a virtual link arbitration table based on the connection request and setting an initial static operating threshold for each virtual link; recording an unexpected big data traffic in each link dynamically by each switch; maintaining respective dynamic threshold by each virtual link; and judging whether current shared links are idle by the virtual link arbitration table when the service traffic in one link reaches the operating threshold of the current link, and activating one shared link for transmission if idle shared links exist. The dynamic operating threshold based efficient traffic control method improves the processing capability for the unexpected big data traffic in the network, the bandwidth utilization efficiency and the transmission efficiency, and reduces energy consumption, packet loss probability and network delay.

Description

technical field [0001] The invention relates to an effective flow control method based on a dynamic working threshold, which belongs to the technical field of computer networks. Background technique [0002] With the rapid development of power system network technology, the structure of power communication network is becoming more and more complex, and the network business is becoming more and more diversified. The power sector needs reliable and effective monitoring of network traffic to reduce energy consumption, packet loss rate, and network delay. The switch has the functions of flow limitation and storm suppression, and has important application value in the smart substation network. However, some problems of high-performance computing network technology itself also affect the security and performance of the system in the station, such as network storms, network congestion, traffic management and control, etc. In order to avoid systemic risks, the planning and design ...

Problems solved by technology

However, because the power grid often has the characteristics of sudden large traffic, the threshold is set as a static threshold according to different network services. If the selected threshold is too low, the switch will switch frequently, which will increase delay and energy consumption.

On the contrary, when the threshold is set high, the length of the queue will be increased, the delay will be increased, and the bandwidth utilization rate will be reduced. When the burst traffic arrives, it will cause the loss of data packets, so the static threshold is not an effective configuration method.
