Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
In the drawings of the specific embodiments of the present invention, in order to better and more clearly describe the working principle of each element in the system, the connection relationship of each part in the device is represented, but only the relative positional relationship between each element is clearly distinguished, and the limitations on the signal transmission direction, connection sequence and the structure size, dimension and shape of each part in the element or structure cannot be constructed.
As shown in fig. 1, the flow chart of the method for constructing a multi-range scene for power network security according to the present invention includes the following steps:
s1, receiving requests of expanded target range scenes sent by target ranges to other standby target ranges in a plurality of target range systems, matching the standby target ranges meeting the requirements according to a predefined scene demand space, and distributing virtual operation channels.
Wherein the target range is a range being used in a plurality of range systems, and the request for expanding the range scene includes: and (5) identifying the standby target range meeting the requirements. The method specifically comprises the following steps:
s11, monitoring the response of a plurality of other standby ranges to the request of the extended range scene according to the predefined scene demand space, and judging whether an idle standby range meeting the predefined scene demand space exists or not, so that the standby ranges meeting the requirements are matched.
And S12, matching the ID of the standby target range to the ID of the target range according to the ID of the standby target range meeting the predefined scene demand space, and allocating a virtual operation channel between the ID of the standby target range and the ID of the target range.
S2, predicting the state of the physical machine load of the target range, judging whether the main operation channel of the virtual operation channel is fully loaded, if not fully loaded, carrying out resource transfer to the standby range meeting the requirements through the main operation channel, and if fully loaded, carrying out resource transfer by utilizing the relay operation channel of the virtual operation channel.
The resource transfer begins by gathering information. And calculating the overall load of the target range according to the load information of all the physical machines in the target range, and further judging whether the main operation channel of the virtual operation channel is full. If the main operation channel is not fully loaded, the load information of the physical machine is continuously monitored, and if the main operation channel is fully loaded, a relay load transfer mechanism is triggered.
The relay load transfer mechanism specifically includes:
firstly, classifying the physical machines according to the load state of each physical machine in a target range, respectively dividing the physical machines into a set S, D, QD, wherein a set S is the physical machine with the current too high load, a set D is the physical machine, and a set QD is the physical machine.
And then sorting the physical machines in the set S according to the descending order of the load, selecting the physical machine with the largest load, and transferring the resources on the physical machine through the relay operation channel of the virtual operation channel.
And finally, sorting the physical machines in the set D, QD according to the ascending order of the load size, and selecting the proper resources of the physical machines to finish the transfer.
Although it is necessary to migrate out the resources of some physical machines to reduce the load, it is necessary to make a further judgment because the remaining life of the physical machine in the range is known, and the physical machine to be destroyed does not have to be diverted out.
If the residual life of the physical machine is less than LI th And after destroying these physical machines, moves them out of the set S.
And after the processing of the set S is finished, judging the state of the whole load of the current target range, and if the current target range is not fully loaded, transferring resources to the standby target range meeting the requirements through a main operation channel of the virtual operation channel. If the relay operation channel is full, the steps are continuously repeated, and the relay operation channel is utilized for transferring the resources.
If the communication system is fully loaded, a temporary ultra-high density communication environment can be caused, overload is very easy to occur to transfer equipment responsible for the channel, and the overall time delay and throughput of a communication system are further influenced.
After the relay operation channel is added, corresponding co-frequency and adjacent frequency interference can occur, channel conflict is caused to influence resource transfer, and the embodiment adopts channel selection and resource allocation to reduce interference generated by overlapping parts. The algorithm steps of channel selection and resource allocation are as follows:
calculating a primary operating channel ap i With the relay operating channel ap R Interference power W (ap) i ,ap R ) The method comprises the following steps:
W（ap i ,ap R ）= r（ap i ,ap R ）R（ap i ,ap R ）；
wherein r (ap) i ,ap R ) Operating channel ap as master i With the relay operating channel ap R The degree of channel overlap between, R (ap) i ,ap R ) Representing relay operation channel ap R Receiving a primary operating channel ap i Is a signal strength value of (a).

Firstly, traversing all M channels which can be used as relay operation channels, and comprehensively calculating the channel combination with the minimum total interference power Pmin to be a plurality of target relay operation channels.
The total interference power P for selecting different channel combinations is calculated:
the resource rate SINR received by the target relay operation channel terminal is related to:
s is the transmission power of the main operation channel, P is the total interference power, N 0 For the ambient noise power, the interference of different target relay operation channels to the main operation channel is brought into:
under the given bandwidth of the communication system, the maximum transmission rate of the channel can be improved by improving the S1NR in transmission, and the overall throughput of the system is improved.
And S3, verifying the expansion performance of the range scene by judging the processor load degree and the communication condition of the standby range.
The load degree is judged by the processor load index of the standby target range, the communication condition is judged by the channel communication index, and the processor load index and the channel communication index are defined as follows:
the processor load index SI judges the load degree of the physical server by comparing the number of actual deployment points of each processor with the number of deployment points of expected points, and the calculation mode is as follows:
wherein T is the number of processors, n i Weight value s representing ith processor i Representing the number of actual deployment points of the ith processor, e i Representing the number of points at which the ith processor is expected to be deployed. The lower the SI, the more balanced the processor load.
The processor communication index TI determines the communication condition by calculating the sum of all channel communication indexes in the following manner:
where W is the number of communication channels,
and represents the communication index of terminal x and terminal y on the jth communication channel. The smaller the TI, the smaller the traffic of the individual signals and the better the communication conditions throughout the transfer.
In a preferred embodiment, there may be a plurality of alternate ranges that match the requirements. Specifically, a state space for a plurality of alternate ranges is determined.
And defining a state space according to the processor utilization rate of the standby target range, the quality of service quality marks and the number of servers as state information. The state S (t) of the reserve range at time t is defined as:
wherein h is max The number of desired deployment points for the processor in the back-up range is a constant value; f (t) is the reserve range demand match,
f (t) when 0 indicates that the reserve target range meets the predefined scene demand space, and F (t) when 1 indicates that the reserve target range does not meet the predefined scene demand space; h (t) is the number of actual deployment points of the processor at the moment t in the current standby target range, and H (t) is more than or equal to 0 and less than or equal to H max The method comprises the steps of carrying out a first treatment on the surface of the U (t) is the average utilization of all processors in the reserve range,
