The specific implementation of the mobile terminal of the present invention is substantially the same as the following embodiments of the data distribution method, and will not be described herein again.
Based on the above structure, various embodiments of the data distribution method of the present invention are proposed.
The invention provides a data distribution method.
Referring to fig. 2, fig. 2 is a process diagram of a first embodiment of the data distribution method of the present invention.
In the present embodiment, an embodiment of a data distribution method is provided, and it should be noted that although a logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that here.
In this embodiment, the data distribution method includes:
step S10, receiving a request data packet sent by a user terminal through a distribution server;
the distribution server is used for distributing the received request data packets to each storage server according to a certain rule, so that the condition that one storage server receives a plurality of request data packets and the resource distribution of the storage servers is uneven is avoided. The request data packet comprises a request data reading packet and a request data writing packet, the request data reading packet is used for reading data corresponding to data items in the request data reading packet from the storage server by the user side, the request data writing packet is used for writing data corresponding to the data items in the request data writing packet into the storage server by the user side, and the request data reading packet and the request data writing packet sent by the user side are received through the distribution server.
Step S20, determining a destination server that receives the request packet according to the number value of the request packet, and sending the request packet to the destination server.
The request packets are assigned with number values, and different request packets have different number values, which are continuous natural numbers. The distribution server calculates the number of the storage server receiving the request data packet according to the number value of the request data packet, and determines the storage server with the number as the target server.
It should be noted that, data stored in all storage servers in the current data storage system is the same, and when a request data packet received by a distribution server is a request data packet, no matter which storage server the request data packet is sent to, data corresponding to a data item in the request data packet can be read.
Further, before step S20, the method further includes:
and a, based on the sequence of the request data packet received by the distribution server, allocating a code value to the request data packet by using a counter in the distribution server.
The request data packets are sent to the distribution server in sequence, a counter of the distribution server allocates a number value to each received request data packet, the number values are allocated to the request data packets based on the sequence of the request data packets received by the distribution server, and it can be understood that the number values are continuous natural numbers, for example, the distribution server allocates a number value 0 to a first received request data packet, allocates a number value 1 to a second received request data packet, and the number value size is 1 more than that allocated at the previous time when the number value is allocated each time. It should be noted that, this embodiment only provides a method for allocating a number value to a request packet by an allocation server, and other methods for allocating a number value to a request packet are also within the protection scope of this embodiment.
In this embodiment, the distribution server receives the request data packet sent by the user side, determines the target server receiving the request data packet according to the number value of the request data packet, and sends the request data packet to the target server, and this way of determining the target server receiving the request data packet according to the number value of the request data packet can implement that each request data packet is sent to each storage server under the data storage system, thereby avoiding the situation of high-load operation caused by receiving and processing more request data packets by only one or several storage servers.
Further, a second embodiment of the data distribution method of the present invention is proposed. The second embodiment of the data distribution method differs from the first embodiment of the data distribution method in that the data distribution method further includes:
and b, numbering all storage servers in the current data storage system from the minimum natural number by taking 1 as an increment unit.
All servers in the current data storage system are numbered before determining the target server to receive the request packet. Starting from the minimum natural number 0, with 1 as an increment unit, all storage servers in the current data storage system are numbered with 0, 1, 2 … … N in sequence, and N is the maximum number.
Further, the step of determining the target server receiving the request packet according to the number value of the request packet includes:
step c, acquiring the total number of storage servers in the current data storage system;
and d, dividing the code value by the total number to obtain a remainder after quotient division, and determining a target server receiving the request data packet corresponding to the code value as a storage server with the same number and the remainder.
First, the total number of storage servers in the current data storage system is obtained, and it can be understood that the maximum number of the storage servers is N, and then the total number of the storage servers is N + 1.
Dividing the number value of the received request data packet by the total number N +1 of the storage servers to obtain a remainder, wherein when the number value is divided by N +1 in an integer way, the remainder is 0, and it can be understood that all possible values of the remainder after quotient division are the number range 0, 1, 2 … … N of the storage servers, and the storage server with the same number as the remainder corresponding to the request data packet is determined as a target server. For example, the number value of the request packet is 0, 1, 2, 3, 4, 5, 6, 7, the total number of the storage servers is 6, the remainder corresponding to the request packet with the number value of 0 is 0, and the remainder corresponding to the request packet with the number value of 0 is 0; the remainder corresponding to the request data packet with the code value of 1 is 1; the remainder corresponding to the request data packet with the code value of 2 is 2; the remainder corresponding to the request data packet with the code value of 3 is 3; the remainder corresponding to the request data packet with the code value of 4 is 4; the remainder corresponding to the request data packet with the code value of 4 is 4; the remainder corresponding to the request packet with the code value of 6 is 0; the remainder corresponding to the request packet with the number value of 7 is 1, so that the destination server receiving the request packet with the number values of 0, 1, 2, 3, 4, 5, 6, 7 is determined as the storage server with the number values of 0, 1, 2, 3, 4, 5, 0, 1, and it can be understood that the request packet can be distributed to the storage servers of the data storage system in a balanced manner by obtaining the remainder by quotient division to determine the destination server.
In the embodiment, the storage servers in the current data storage system are numbered and the total number of the storage servers is obtained, the number value of the request data packet is divided by the total number to obtain the remainder, the storage servers with the numbers equal to the remainder are determined as the target servers, the request data packet is distributed to all the servers in the data storage system in a balanced manner, and the condition that a certain storage server runs under a high load due to too many request data packets processed by the certain storage server and the condition that resources of certain storage servers are idle are avoided.
