Example Embodiment

[0062] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0063] The method of the present invention includes the following steps:

[0064] Step 1. Network traffic collection:

[0065] Network traffic collection monitors and analyzes the characteristics and changes of computer network data streams. According to different sources of network traffic, network traffic is divided into network node port traffic, end-to-end IP traffic, and user business data traffic. Embed the collection tool on the network transmission equipment of routers and switches, and collect real-time data of SDH (Synchronous Digital Hierarchy), OTN (Optical Transport Network) and EPON (Ethernet Passive Optical Network) The export data transmission traffic of the device. Use the router's built-in Netflow function to monitor the network flow, and perform statistics on the flow data on the SG-TMS (National Grid Communication Ma...

Abstract

The invention discloses a multi-dimensional power communication network flow prediction method and system; the method comprises the following steps: step 1, network flow is collected; step 2, a multi-dimensional flow prediction method is carried out; step 3, a dynamic weight updating strategy is introduced into a single exponential smoothing algorithm; the system comprises application layer equipment, an interface module, an SDN controller, an SDN coordinator, an SDN device, an OTN device and an EOPN device. The method and the system have the advantages that a cloud service technology is introduced in the adopted data measurement method; an SDN technology is introduced into a data acquisition part; the collected transverse dimension data are trained through a BP neural network algorithm; and an algorithm combined with an FARIMA algorithm and an ELman algorithm is adopted for the collected longitudinal dimension data. The precision of the prediction algorithm is improved; and the singleexponential smoothing algorithm is adopted to update the weight output by the multi-dimensional prediction algorithm, so that the fluctuation dimension of errors is reduced.

Description

technical field [0001] The invention relates to a multi-dimensional power communication network flow prediction method and system, belonging to the field of power communication network network flow prediction management. Background technique [0002] As the second network covering the whole area of ​​the power system, the communication network is the only channel to carry the important data of power grid stability, protection, control, and information. The stability, reliability, and security of its transmission directly affect the reliability of power grid transmission lines. run. If the power grid has a serious failure due to network performance problems, it will cause losses to national people's livelihood, property and security. [0003] With the in-depth advancement of the smart grid and the national grid, the scale of the power communication network continues to expand, the number of SDH (Synchronous Digital Hierarchy, Synchronous Digital System) equipment increases, ...
