Fig. 2 is a network diagram of a cinema server cluster of intelligent cinema construction test points currently developed by Beijing postal university and Suzhou Wuyang cinema. The system mainly comprises the following modules:
and the load balancing server is used for distributing the service request to the actually executed server according to a preset dynamic load balancing method, so that the response time of the whole system is reduced.
The hardware configuration of the servers in the server cluster is difficult to unify due to various reasons such as long service time, hardware replacement or software upgrade of each server in the production environment, so that most of the server clusters are heterogeneous cluster systems. A heterogeneous server cluster system S consisting of n servers with different performances can be represented by a set S = { S = { (S) } 1 ，s 2 ，s 3 ，s 4 ，......，s n }。
The method takes four basic performance indexes of CPU frequency, disk I/O speed, memory size and network bandwidth as server load state evaluation parameters, the influence weights of the performance indexes in different services are different, and the weights of the influence degrees of the CPU frequency, the disk I/O speed, the memory size and the network bandwidth on the server performance are respectively w cpu ，w disk ，w storage ，w tape Is shown, wherein:
w cpu +w disk +w storage +w tape ＝1
node server s i The initial performance indexes of CPU frequency, disk I/O speed, memory size and network bandwidth are respectively used
Figure RE-GDA0003784500950000091
To indicate. Then, the server s i The initial performance of (a) can be expressed as:
Figure RE-GDA0003784500950000092
considering that the occupancy of the server performance index cannot objectively reflect the real load capacity of the server, the situation that the occupancy of the performance index of a high-performance server A is smaller than that of a low-performance server B, but the request response time of the server A is still smaller than that of the server B exists, the load evaluation model carries out evaluation by using the current load rate of the server, and a node s i The actual load of (a) is:
Figure RE-GDA0003784500950000101
wherein the actual performance of each performance indicator is equal to the product of the initial performance and its occupancy in the production environment. Then, the node server s i The total remaining load capacity of (c) is:
Figure RE-GDA0003784500950000102
s i the remaining load ratios of (a) are:
Figure RE-GDA0003784500950000103
as shown in fig. 3, the preset dynamic load balancing method includes:
and calculating the average value, the variance and the deviation of all the request response times of the target server in a preset feedback period, and obtaining the maximum value of the average response time according to the difference value of the average value and the variance of the request response times in the first feedback period when the system stably operates. The specific value of the preset feedback period is not specifically limited in the embodiment of the present application, and can be set according to actual conditions.
Ideally, the response time of each node to the request is the same, and when the dispersion degree of the response time of each node to the request is larger, the current performance attenuation speed of the server node is higher, the dispersion degree of the response time of the server to the request is selected to quantify the dispersion degree of the response time. In order to accurately acquire the load state of the server and reduce the performance reduction of the server caused by frequent adjustment of the weight, the evaluation model takes 60s as a feedback period, the server records the response time of each request, and the average value, the variance and the deviation of all the request response time in the period are calculated at the end of each period.
Wherein, the average value of all request response time in the feedback period is calculated according to the following formula:
Figure RE-GDA0003784500950000104
the variance of all request response times within a feedback period is calculated according to the following formula:
Figure RE-GDA0003784500950000105
calculating the deviation degree of all request response time in the feedback period according to the following formula:
Figure RE-GDA0003784500950000111
calculating the variation amplitude of the request response time deviation degree in two adjacent feedback periods according to the following formula:
Figure RE-GDA0003784500950000112
wherein the variable descriptions are shown in the following table:
Figure RE-GDA0003784500950000113
the first group of request responses after the weight correction is completed and the system operation is stable occur in the best server performance state, so the average value and variance of the group of request time are taken as reference standard values and recorded as
Figure RE-GDA0003784500950000114
When the number of clusters is large and high concurrent requests exist, the response time of the server to a single request accords with normal distribution, so the maximum value Max (T) of the average response time of each group of data is set as
Figure RE-GDA0003784500950000115
The current load condition of the server can be described according to the threshold value as shown in the following table:
Figure RE-GDA0003784500950000116
further, the weights are updated according to the state in which the server is located. When the server is in the state 1, the server is indicated to be overloaded seriously, the server cluster is unbalanced seriously, if the server cluster is not adjusted in time, the hardware of the server can be damaged, the weight of the server needs to be set to be 0 in the task scheduling process of the next period, and a new task is not distributed to the server any more. When the server is in the state 2, the performance of the server is seriously reduced, the occupancy rate of each performance index of the server needs to be checked, and the influence degree of each performance index is adjusted in time.
Specifically, if the average value of all the request response times of the target server in the current feedback period is smaller than the maximum value of the average response time, and the variation amplitude of the deviation degree in two adjacent feedback periods is greater than or equal to a preset threshold value, the weight of each performance index of the target server is updated.
Calculating the average value of the current occupancy rates of all the performance indexes of all the servers in the server cluster; when the occupancy rate of the target performance index of the target server is larger than or equal to the corresponding occupancy rate average value, increasing the weight corresponding to the target performance index of the target server; and when the occupancy rate of the target performance index of the target server is smaller than the corresponding occupancy rate average value, reducing the weight corresponding to the target performance index of the target server.
For a single server, a single node s may be passed through the server i Occupancy rate P of each performance index si And the average value of the current occupancy rates of all the performance indexes of all the servers of the server cluster
Figure RE-GDA0003784500950000127
To adjust the weight of each performance indicator in a single server node, wherein
Figure RE-GDA0003784500950000122
The update algorithm is described below with the CPU frequency as an example:
when in use
Figure RE-GDA0003784500950000123
Then, the server node s is considered i The influence of the CPU frequency on the server is increased, and the corresponding weight is increasedWeight value w cpu Otherwise, the server node s is considered i The influence of the CPU frequency on the server is reduced, and the corresponding weight value w is reduced at the moment cpu The weight change amount is:
Figure RE-GDA0003784500950000124
in order to make the weight of each performance index equal to 1, the weight is modified as follows:
Figure RE-GDA0003784500950000125
at this time, the node load capacity is updated as follows:
Figure RE-GDA0003784500950000126
the node weight is updated as:
Figure RE-GDA0003784500950000131
and if the average value of all the request response times of the target server in the current feedback period is greater than or equal to the maximum value of the average response time, setting the node weight of the target server to be 0.
And if the average value of all the request response times of the target server in the current feedback period is smaller than the maximum value of the average response time, and the variation amplitude of the deviation degree in the two adjacent feedback periods is smaller than a preset threshold value, not updating the weight of the target server.
