Description
Technical Field
The present invention relates to the field of power communications technologies, and in particular, to a method, an apparatus, a terminal device, and a medium for optimizing a power service route.
Background
With the rapid increase of the traffic volume of the automatic demand response, the uncertainty of the network data flow caused by the traffic burstiness causes the traffic distribution to be extremely uneven, which may cause network congestion in the interaction process of the automatic demand response information, and greatly affect the service quality of the automatic demand response traffic. In order to fully utilize the allocation capability of communication network resources, effectively suppress the congestion of the power demand response communication network, and balance the load in the network, so as to improve the throughput and the reliability of information interaction of the communication network, it is necessary to reasonably optimize the service distribution of the power demand response communication network.
At present, the most common way is to balance load and suppress congestion of the communication network by optimizing routing. However, in the existing work, in the process of optimizing the route, the time delay and the bandwidth requirement are mainly fused to establish an objective function, so that the optimal route is selected. The traditional method for solving the optimal routing problem under the multi-constraint condition is to adopt a heuristic algorithm, such as a particle swarm algorithm, an ant colony algorithm and the like. However, the algorithms have some disadvantages, such as the particle swarm optimization is easy to fall into local optimization, so that the algorithms are often limited in practical application. The traditional routing algorithm usually allocates a path with the minimum measurement parameter value to the power communication service as a route, the allocation method cannot meet the requirement of the power demand response service on the service quality, and the reliability of a communication network cannot be guaranteed. In addition, a routing algorithm for solving the optimal unicast path of a certain service only and neglecting the mutual influence between the unicast path and other services cannot well and uniformly distribute the services and optimize network resources.

in the formula (I), the compound is shown in the specification,

wherein C is a constant and NXRepresentative link VXAnd E is the total bandwidth of the built power communication network.
Specifically, in F (V)X,NX)<E/2, analyzing each used link, and judging the O values of all the used links one by one or simultaneously;
at E/2 ≦ F (V)X,NX)<0.95E, the link V with the highest bandwidth occupancy in the used link is limited due to network resource problemsIAnd optimizing calculation is performed firstly, so that system crash caused by simultaneous calculation is avoided.

It should be noted that, in the event of O e [0.80,0.95), the link replacement principle is to replace the node that is the second closest to the device and then calculate the O value, if the O value is still lower than the original link O value or less than 0.90, replace the node link in the connection layer, and then calculate the O value again until the O e [0.95,0.98) is obtained, mark the link corresponding to the device.
And S40, establishing a problem database according to the distribution result, and optimizing the establishment range and the density of the link nodes by using the problem database.
Specifically, a problem database is established in the step, the percentage of the total number of the historical distribution links occupied by the links with O values in the range of O [0.90, 0.98) after the first distribution according to the latest distribution principle is counted, then the links with O [0.80, 0.85) after the first distribution are marked when the percentage is lower than 93%, the attribute difference between the links with O values higher than 95% after the redistribution and the originally distributed links is checked, and finally the establishment range and the establishment density of the nodes are optimized according to the attribute difference.
