Description

Cloud storage implementation method and cloud storage system

Technical Field

The invention relates to the technical field of cloud storage, in particular to a cloud storage implementation method and a cloud storage system.

Background

Cloud storage gradually reveals the forefront due to the characteristics of massive storage space, high reliability, high concurrency, high expandability, high cost performance and the like. The high concurrency of cloud storage is mainly embodied in that different files can be dispersed on different storage servers, so that the cloud storage can be almost infinitely expanded for writing concurrency and reading concurrency of different files; however, for the same file, although the read concurrency capability can be improved by increasing the number of copies on different storage servers, the purpose of this is to increase reliability, and due to the limitation of the total capacity, it is impossible to copy each file without limitation, so that the improvement of the read concurrency of the same file is extremely limited. In practical applications, for example, in the process of detecting a great public security case, a great number of users often access the same video recording at the same time in a burst manner, which may cause the relevant storage server to be overloaded.

In order to overcome the defects, a cloud storage method and a cloud storage system are provided, and under the condition that the complexity of a client and the extra flow of a client network are not increased, the bottleneck of reading concurrent data of the same multimedia file by the cloud storage system is solved, and the load of a related storage server is reduced.

The cloud storage method comprises the following steps:

s2, the control server coordinates the load balance of the storage server and establishes a file block index corresponding to the storage server for the multimedia file; and

and S3, the streaming media server receives a multimedia file playing request sent by the client, and requests a required file block from a storage server appointed by the control server according to the coordination of the control server on the load balance of each storage server.

In step S3, when the specified storage server stores the required file block, the specified storage server sends the required file block to the streaming server, and returns the required file block to the client; and when the specified storage server does not store the required file block, the specified storage server downloads the required file block from the storage server storing the required file block for backup, sends the required file block to the streaming media server, and returns the required file block to the client.

The step of coordinating the load balance of each storage server by the control server comprises the following steps:

the control server checks the load conditions of all storage servers storing the required file blocks according to the file block indexes, if the storage servers with normal load exist, the storage servers with lighter load are selected and the server addresses of the storage servers are returned to the streaming media server to serve as the designated storage servers; if no storage server with normal load exists, selecting a storage server with light load from the storage servers which do not store the required file blocks, and returning the server address of the storage server to the streaming media server as the designated storage server.

The method for judging whether the load of the storage server is normal by the control server is as follows: the control server presets a load threshold value, if the load of the storage server is smaller than the threshold value, the storage server is judged to have normal load, and if the load of the storage server is larger than the threshold value, the storage server is judged not to have normal load.

Further comprising: when the needed file block is backed up in the appointed storage server, the notification control server generates the information of new backup.

After the control server receives the information for generating the new backup, the method further comprises the following steps: the control server accumulates the number of the backup copies and the new backup number, compares the accumulated backup number with a preset standard backup number, if the accumulated backup number is greater than the standard backup number, sends a command of deleting the backup to at least one storage server with the highest load storing the required file blocks, and the storage server receiving the command of deleting the backup deletes the required file blocks when the required file blocks are not used; and if the accumulated backup number is less than or equal to the standard number of copies, sending a backup command to at least one storage server which does not store the required file blocks and has the lightest load, and backing up the required file blocks by the storage server which receives the backup command.

The number of the controllers for handling the switch communication failure information can be several, each controller for handling the switch communication failure information monitors the number of the switch communication failure information to be handled obtained by the controller for handling the switch communication failure information, the switch communication failure information is added into a linked list of the switch communication failure information, when a switch is in a large range or other controllers for handling the switch communication failure information have problems, the switch communication failure information is transferred into the controller for handling the switch communication failure information, or when the controllers for handling the switch communication failure information have local problems, a state that the switch communication failure information to be handled is greatly increased is generated, namely, the problem that the switch communication failure information is greatly increased is met, the controller for processing the switch communication failure information with stable working state can often obtain the situation that the performance of processing the switch communication failure information is insufficient, the number B1 of the switch communication failure information which can be processed by the controller for processing the switch communication failure information in a set time range and the maximum number of the switch communication failure information which can be processed by the controller for processing the switch communication failure information in the past are used for determining the variation of the weakened performance of processing the switch communication failure information according with the variation of the weakened performance of processing the switch communication failure information, and the controller for processing the switch communication failure information and the controller for acquiring the switch communication failure information execute the control system of the temporary switch communication failure information together, the controller for the switch communication failure information processing screens the secondary switch communication failure information in the linked list of the switch communication failure information by running a screening specification prepared in advance, transmits notification information containing the variation amount of the weakened switch communication failure information processing performance and the weight average value of the switch communication failure in the linked list of the switch communication failure to the controller for the switch communication failure information acquisition, and the controller for the switch communication failure information acquisition determines the set weight Q1 of the controller for the switch communication failure information acquisition according to the content in the notification information and terminates the switch communication failure information of which the transmission weight is less than the set weight Q1. Therefore, the method can avoid or reduce the defects of blockage of the switch communication failure information and loss of the switch communication failure information, and synchronously ensures that the switch communication failure information which cannot be transmitted to the controller for processing the switch communication failure information in each switch is determined according to the fluctuation amount of weakened switch communication failure information processing performance, so that the switch communication failure information with great authority can be processed under the condition of weakened switch communication failure information processing performance, and a great deal of switch communication failure information can be transmitted to the controller for processing the switch communication failure information under the condition of the switch communication failure information processing performance to the maximum extent.

The controller for acquiring the switch communication failure information is used for acquiring the switch communication failure information of the switch of the cloud platform and transmitting the switch communication failure information to the controller for disposing the switch communication failure information, the controller for disposing the switch communication failure information adds the switch communication failure information to be disposed to the tail of a linked list of the switch communication failure information, and in addition, the controller performs information analysis disposition on the switch communication failure information; the controller for the switch communication failure information disposal also comprises a storage unit for storing the switch communication failure information;

the switch communication failure information comprises an identifier of the switch communication failure information, the weight of the switch communication failure information, the time when the switch communication failure occurs, the identifier of the switch with the communication failure, the type of the switch with the communication failure and the type of the switch communication failure;

the information transmission sequence of the switch communication failure information in the controller for acquiring the switch communication failure information is ordered according to the front-back sequence of the occurrence time of the switch communication failure information;

however, the occurrence of a large amount of communication failure information in some unusual situations causes extreme imbalance in the transmission of communication failure information by the switch and the acquisition and handling of communication failure information by the controller for communication failure information handling, as a large-scale problem occurs due to the problem of the switch circuit, the number of communication failures of the switch is greatly increased, the number of the communication failure information transmitted by the controller for acquiring the communication failure information is greatly increased, communication blockage and the communication failure information are often caused to be lost, and the number of the communication failure information overstocked in the linked list of the communication failure information of the controller for disposing the communication failure information is too large, so that the efficient performance of disposing the communication failure information is damaged, and particularly, the disposing time delay of the communication failure information with a large problem is increased.

To solve such problems, the following steps are thus performed:

s1: the controller for the switch communication failure information disposal regularly monitors whether the performance of the controller for the switch communication failure information disposal for disposing the switch communication failure information is weakened or not according to a set time interval;

s2: all controllers for handling switch communication failure information are respectively provided with the number B2 of the largest switch communication failure information which can be handled in a set time length range in advance, (the number B2 of the largest switch communication failure information which can be handled in the set time length range is the number of the largest switch communication failure information which can be handled by the controllers for handling switch communication failure information in the set time length range in the past) the number B1 of switch communication failure information which can be handled at present in the set time length range (the number B2 of the switch communication failure information which can be handled at present can be obtained through tests), if in the set time length range, the number B2 of the largest switch communication failure information which can be handled in the set time length range is judged to be larger than the number B1 of the switch communication failure information which can be handled at present, or the number of the switch communication failure information in the linked list of the switch communication failure information is greater than the number B2 of the largest switch communication failure information which can be handled in the set time length range, so that the switch communication failure information handling performance of the controller for the switch communication failure information handling is judged to be weakened;

s3: when the controller for the switch communication failure information processing judges that the performance of the switch communication failure information processing is weakened according to the set time interval, the controller for the switch communication failure information processing operates a preset screening mode to screen out secondary switch communication failure information in a linked list of the switch communication failure information; this prevents the secondary switch communication failure information from being disposed, and also cleans up the adverse effect of the secondary switch communication failure information on the weight average. The controller for handling the switch communication failure information can screen out the secondary switch communication failure information only under the condition that the switch communication failure information handling performance of the controller for handling the switch communication failure information is weakened, but does not screen out the secondary switch communication failure information under other conditions, so that the completeness of the switch communication failure information can be ensured to the maximum extent under the condition that the switch communication failure information handling performance of the controller for handling the switch communication failure information is weakened, and the controller is favorable for better handling under the communication failure.

In addition, secondary switch communication failure information in the linked list of the switch communication failure information can not be screened out by not operating a preset screening mode, and the weight average value of all switch communication failure information in the linked list of the switch communication failure information is directly calculated;

s4: the controller for switch communication failure information handling transmits notification information of the controller for switch communication failure information handling performance reduction with a reduction value W1 of the switch communication failure information handling performance reduction of the controller for switch communication failure information handling and a weighted average value Q1 of the switch communication failure information toward the controller for switch communication failure information acquisition;

s5: the controller for acquiring the switch communication failure information determines a set weight Q2 by means of the obtained weakening value W1 of the switch communication failure information handling performance weakening of the controller for handling the switch communication failure information and the weight mean value Q1 of the switch communication failure information and the set weight adjusting coefficient Z of the controller for acquiring the switch communication failure information;

the set weight Q2 is obtained by equation (1):

Q2＝Q1(1+Z*W1) (1)

and Z is a positive number less than 1;

the controller for switch communication failure information acquisition decides a weight adjustment coefficient Z set by the controller for switch communication failure information acquisition by:

the controller for acquiring the switch communication failure information sums up the number of all switch communication failure information acquired by the controller for acquiring the switch communication failure information and the number of the switch communication failure information with the maximum weight; of course, the switch communication failure information with the largest weight is to be dealt with as early as possible, and then the controller for acquiring the switch communication failure information calculates a quotient obtained by dividing the number of the switch communication failure information with the largest weight in the controller for acquiring the switch communication failure information by the number of all the switch communication failure information; then, if the critical value of the first adjusting coefficient is greater than the quotient, the number of the switch communication failure information with the maximum weight in the switch communication failure information is still not large, that is, the controller for acquiring the switch communication failure information does not need to take care of, and the set weight adjusting coefficient is set to be a pure fraction greater than one fifth; if the critical value of the first adjusting coefficient is smaller than the quotient, the number of the switch communication failure information with the maximum weight in the switch communication failure information is large, namely the controller for acquiring the switch communication failure information needs to take care of, and the set weight adjusting coefficient is set to be a pure fraction smaller than one fifth; the critical value of the first adjusting coefficient is any pure decimal between one fifth and two fifths;

in this way, when the handling performance of the controller for handling the switch communication failure information is weakened, when some switch communication failure information is determined not to be transmitted by the weight set by the controller for acquiring the switch communication failure information, the method combines the information that the handling performance of the controller for handling the switch communication failure information is weakened and the information that can embody the weight adjustment coefficient of the number of the switch communication failure information with the maximum weight in the controller for acquiring the switch communication failure information to determine the weight set by the controller for acquiring the switch communication failure information, so that the determination of the set weight can better embody the current state of the controller for handling the switch communication failure information, and when the switch communication failure information with the maximum weight is determined to be handled, the larger amount of the switch communication failure information can be transmitted to the controller for handling the switch communication failure information The system realizes the handling, so the better handling of the problem that communication failure is greatly increased.

S5: the controller for switch communication failure information acquisition screens out switch communication failure information conforming to a removal method of already acquired switch communication failure information of the controller for switch communication failure information acquisition using a removal method equipped in advance, and terminates transmission of the removed switch communication failure information having a weight smaller than a set weight Q2 of the controller originally used for switch communication failure information acquisition toward the controller for switch communication failure information handling; the controller for switch communication failure information acquisition stores the removed switch communication failure information, and transmits the switch communication failure information removed by the removal method to the controller for switch communication failure information handling when the switch performance of the controller for switch communication failure information handling is restored. The removing method is based on the operation formula of the and or of the characteristics of the switch communication failure information, wherein the characteristics of the switch communication failure information comprise the type of the switch communication failure, the position of the switch communication failure information and the reason of the switch communication failure information.

If the handling performance of the controller for the switch communication failure information handling is not recovered, the execution is maintained in step S5, and if the handling performance of the controller for the switch communication failure information handling is recovered, the execution is shifted to step S6;

step S6: the controller for switch communication failure information processing transfers notification information for processing performance restoration to the controller for switch communication failure information acquisition as feedback of the notification information to the controller for switch communication failure information processing, and the controller for switch communication failure information acquisition also normally transfers switch communication failure information occurring in a switch connected thereto to the controller for switch communication failure information processing.

When the controller for handling the switch communication failure information determines that the handling performance of the switch communication failure information of the controller for handling the switch communication failure information is weakened by the number of the switch communication failure information of the linked list of the switch communication failure information according to the set time range, the controller for handling the switch communication failure information performs the judgment of the relevance of the switch communication failure information on the switch communication failure information after the linked list of the switch communication failure information is screened, and handles the switch communication failure information with the relevance in the linked list of the switch communication failure information as a whole, specifically as follows:

the controller for switch communication failure information handling judges whether or not switch communication failure information is a switch communication failure information that is classified into a class of a switch that has a consistent communication failure and the class of a switch communication failure does not coincide by virtue of the class of the switch that has a communication failure within the switch communication failure information and the class of the switch communication failure, and then handles the switch communication failure information that is classified into the class of the switch that has a consistent communication failure and the class of the switch communication failure does not coincide as switch communication failure information with correlation as a whole.

The controller for processing the switch communication failure information performs the judgment of the relevance of the switch communication failure information on the switch communication failure information after the chain table of the switch communication failure information is removed, so that when the processing performance of the switch communication failure information of the controller for processing the switch communication failure information is weakened, the processing efficiency of the switch communication failure information in the chain table of the switch communication failure information can be improved, and the blockage of the switch communication failure information caused by the weakening of the processing performance of the switch communication failure information can be reduced.

The method for the controller for the switch communication failure information handling to regularly monitor whether the performance of the controller for the switch communication failure information handling to handle the switch communication failure information is weakened or not according to the set time interval comprises the following steps:

s1-1: the number of the switch communication failure information in the linked list of the switch communication failure information is M1;

step 1-2: the switch communication failure information handling performance of the controller for switch communication failure information handling is thus weakened due to a problem of the controller for switch communication failure information handling, and a weakening value W1 of the switch communication failure information handling performance weakening of the controller for switch communication failure information handling is obtained by equation (2):

W1＝(B2-B1)/B1 (2)

the switch communication failure information handling performance of the controller for switch communication failure information handling is weakened due to a problem of the switch, and a weakening value W1 of the switch communication failure information handling performance weakening of the controller for switch communication failure information handling is obtained by equation (3):

W1＝(M1-B2)/B2 (3)

the switch communication failure information handling performance of the controller for switch communication failure information handling is weakened due to a problem that the number of switch communication failure information becomes large, and a weakening value W1 of the switch communication failure information handling performance weakening of the controller for switch communication failure information handling is obtained by equation (4):

W1＝(M1-B1)/B2 (4)；

at every lapse of a set time interval, S1-1 and S1-2 are performed.

The secondary switch communication failure information is the switch communication failure information caused by software.

In summary, when the handling performance of the controller for handling the switch communication failure information is weakened and when some switch communication failure information is determined not to be transmitted by the weight set by the controller for acquiring the switch communication failure information when the handling performance of the controller for handling the switch communication failure information is weakened, the set weight of the controller for acquiring the switch communication failure information is determined by combining the information that the handling performance of the controller for handling the switch communication failure information is weakened and the information that can represent the weight adjustment coefficient having the largest number of switch communication failure information with the weight in the controller for acquiring the switch communication failure information, so that the determination of the set weight can better represent the current state of the controller for handling the switch communication failure information, when the switch communication failure information with the largest weight is determined to be handled, a larger number of switch communication failure information can be transmitted to the controller for handling the switch communication failure information to be handled, so that the problem of a large amount of communication failure is better handled.
