QoS (Quality of Service) business control method in power telecommunication net

Abstract

The invention discloses a QoS business control method in a power telecommunication net. The method comprises the following steps: providing a business classification standard of the power telecommunication net, setting business importance degree of a power system according to QoS demand, and distributing a DSCP (differentiated services code point) value according to high-low of the business importance degree and class of business; providing a QoS business control step in the power telecommunication net in addition, wherein the step mainly comprises two stages of QoS business identification and QoS route optimization, and two stages are specifically as follows: firstly performing QoS business classification and identification on a business stream entering the power telecommunication net, and then performing QoS route optimization control after obtaining the DSCP value. The QoS business identification have both characteristics of being fast and simple in port matching, robust, low in complexity and good in flexibility, and characteristics of precise and effective in DPI, good in expandability of a flow character analytical method, and small in computation expenditure and storage expenditure; a destination address and the DSCP value are combined for route selection through the QoS route optimization, the routes are distributed according to different power business requirements on the basis of destination route selection, thereby promoting the business transmission quality of the power telecommunication net and realizing the QoS route optimal control.

Description

[0001] technical field [0002] The invention relates to a QoS service control method in an electric power communication network, in particular to a method for classifying service categories in an electric power communication network, and the business importance degree of an electric power system r i Value method, service flow DSCP value distribution method, QoS service control method based on QoS service identification and QoS routing optimization control. Background technique [0003] With the integration of power energy and communication and the rapid development of smart grid, power communication plays an increasingly important role in the power system. The power communication network carries various production and management services in the power system, directly affects the stability and safe production of the power system, and its reliable operation is even more important. [0004] At present, the electric power system is changing from the pure voice service provide...

Problems solved by technology

In this case, if one type of QoS is used to provide communication service guarantee, not only the QoS of each communication service cannot be guaranteed, but also because higher QoS is provided for some services with lower QoS service requirements, resulting in huge waste

At the same time, the QoS security of the system cannot be guaranteed, because once the current QoS system is out of service, all businesses will have no QoS service
