Description

technical field [0001] The invention belongs to the technical field of communication network bandwidth prediction, and relates to a communication bandwidth prediction method for smart power distribution and consumption services facing smart parks. Background technique [0002] In the smart park, there are various forms of energy, various types of smart terminals, and more complex power services. For example, distributed power supply services, energy monitoring services, and control services put forward higher requirements for edge computing and edge communication capabilities. Reasonable power communication planning is the key to smart The basis for the normal operation of the power business in the park, the communication bandwidth plan that does not match the actual situation will lead to redundant waste of communication network resources, or bring problems such as communication service quality that cannot meet the communication business needs between terminals, restricting ...

Problems solved by technology

[0003] There have been some studies in this field. The traditional bandwidth prediction technology uses the method of combining intuitive observation and elastic coefficient to predict the bandwidth of the power distribution communication network, which is compatible with the traditional power distribution business, but the result of the communication bandwidth is usually greater than Actual bandwidth requirements lead to waste of communication resources and low bandwidth utilization

Some experts proposed a bandwidth calculation method based on M / M / 1 / k queuing theory for information collection services, and allocated bandwidth resources with the help of the constraint relationship between communication service quality indicators and bandwidth utilization. There are simplifications in the process, all of which are related to the accuracy of bandwidth prediction, and with the changes in the business operation characteristics of the smart park, the above traffic model cannot accurately describe the arrival process of business data in the smart park, and it is difficult to accurately predict the business bandwidth
