Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a high-speed power service flow identification system and method. Background technique [0002] The data flow direction of the network system in the power system is very different from the traditional network operator network data flow direction. The network data of the operator is mainly the following behaviors, while the power system network data is mainly the above behaviors, and the video data of the network access equipment in the system , Status data, metering data, relay protection data and other central server systems to be uploaded. Most of these data are the main actors. If events occur concurrently, it may cause network congestion. Key data cannot be uploaded to the server accurately in real time, causing The system responds slowly, or even fails to respond in time. Therefore, it is necessary to distinguish service types, increase network permissions...

Problems solved by technology

[0003] The early technology has made many improvements in the business identification algorithm, but the hardware architecture of the whole device is still based on the serial structure, and the business weighting algorithm is relatively simple, or the database query method is used to determine the data priority, simple weighting algorithm or database query The method guarantees the transmission of important data, but it may also cause other non-real-time services to fail to run normally, so it is necessary to improve the simple weighting algorithm and adopt a more reasonable business scheduling algorithm to ensure that important data is transmitted first. Business data can also be transmitted normally without affecting business development. For example, when there is a large amount of wave recording data that needs to be uploaded to the system server, if the video surveillance data is also uploaded to the server at this time, the simple weighting algorithm will reduce the authority of the wave recording data. High, but due to the large transmission volume, the video will be discontinuous, which will have a bad impact on the monitoring business. Therefore, the integral algorithm can be used to consider the tolerance of data delay, so as to obtain the priority of data transmission. In extreme cases, it can also ensure the reliable transmission of most business data without affecting the normal development of business
