Description
Technical field
The present invention relates to fields of communication technology, more particularly, to a kind of high-speed power business flow identification system and method.
Background technique
In electric system the data flow of network system and traditional network operator network data flow direction have it is very big not
Together, the main following behavior master of carrier network data, and the main above behavior master of power system network data, network connects in system
Enter the central server systems all to be uploaded such as video data, status data, continuous data, the relay protection data of equipment,
The above behavior master of these data overwhelming majority, if event is concurrent, it is possible to cause network congestion, critical data can not be quasi- in real time
True uploads onto the server, and causes system response slowly, or even the case where can not timely responding to occur, it is therefore necessary to distinguish industry
Service type improves the network legal power of important business data, it is reliable stable in time to guarantee that important business data transmits, but be simultaneously guarantor
It demonstrate,proves non-real-time service to work normally, in the case where network bandwidth allows, utmostly guarantees that all business are normally carried out.
The technology of early stage has done many improvement in business recognizer, but the hardware structure of whole device is still with serial
Based on structure, business weighting algorithm is also fairly simple, or determines data priority, simple weighted using data base query method
Algorithm or data base query method ensure that significant data transmits, but be also possible to cause other non-real-time services normal
Operation, it is perfect it is therefore necessary to be subject to simple weighting algorithm, more reasonable traffic dispatch is taken, guarantees important number
In the case where according to prioritised transmission, most of business datum also can normal transmission, carry out without influencing business, such as a large amount of when having
It is simple to add if video monitoring data will also upload onto the server at this time when recorder data needs to upload to system server
Algorithm is weighed, recorder data permission can be very high, but since transmission quantity is larger, it is discontinuous to will lead to video, to produce to monitoring business
Raw deleterious effect, it is therefore possible to use integral algorithm, considers the tolerance of data delay, it is excellent to obtain data transmission with this
First grade also can guarantee most of business datum reliable transmission, do not influence business and normally carry out in extreme circumstances.
