Each server runs the same service software and accesses the shared database, so it appears that any one server can provide services to any one user without any problem.
However, this is not the case, because the process of requesting services by the user is continuous, for example, a data packet sent by the user to request login in the trunking system providing e-commerce services, the trunking system verifies that the account password of the user allows login, the user sends a data packet to request to view his/her shopping order, the trunking system responds to a shopping list sent back to the user, if the data packets for processing two service requests sent by the user are the same server in the trunking system, there is certainly no problem, but if the data packets for processing two service requests sent by the user are two servers in the trunking system respectively, the first server needs to send the login status of the user to all other servers after verifying the login of the user, otherwise the other servers will reject services because the user is considered not logged in when processing the second service request data packet sent by the user.
This method of synchronizing the working status of the user among the servers so that any server can provide the service to the user is not preferable because it is very difficult to synchronize and inefficient when the number of servers is large.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the data forwarding method according to the preferred embodiment of the present invention includes the following steps:
step S10, the shunting server reads the user ID in the request data packet and converts the user ID into a numerical value.
Specifically, the method further includes, before the step S10: the method comprises the steps that a distribution server is arranged in a cluster system (the cluster system refers to a system in which a plurality of servers are connected together through a network and provide a certain function together) in advance, and the distribution server is used for receiving all request data packets sent by a user and forwarding data according to the classification of the request data packets. When the specific setting is carried out, the IP of the cluster system is set on the shunting server, and all request data packets sent to the cluster system are controlled to be received by the shunting server at the first time (namely all the request data packets received by the cluster system are sent to the shunting server first).
Specifically, the offload server reads a user ID (for example, the user ID may be a telephone number, a mailbox address, a string of characters, etc.) in the request packet; the shunting server converts the user ID into a numerical value according to a hash algorithm (the input with any length is called as pre-mapping and is converted into the output with fixed length through the hash algorithm, and the output is a hash value); wherein the numerical value is a natural number.
The hash algorithm can convert a string of information (e.g., user ID: abcdef, AAD 400511) with different lengths and different forms into a numerical value, and the numerical values converted from the same information are the same (i.e., the numerical values converted from the same user ID by the hash algorithm are the same). For example, the offload server reads the user ID in the request packet, converts the user ID into a value a according to a hash algorithm, where the value a is a common value, and converts the user IDs with different lengths and forms into the value a for classification, for example, the value a divided by 10 and 0 is classified into the 1 st class, and the value a divided by 10 and 1 is classified into the 2 nd class.
And S20, acquiring the number of all servers providing services in the cluster system, and numbering all the servers in sequence.
Specifically, acquiring all servers and the number of all servers providing services except the offload server in the cluster system; all servers in the cluster system except the distribution server are numbered in sequence, and as shown in fig. 2, a plurality of servers may be numbered as 0 (server 0), 1 (server 1), and 2 (server 2) · · B-1 (server B-1). That is, the number of servers (except for the streaming server) capable of providing services in the current cluster system is obtained as B, and the numbers of the servers are (0, 1,2., B-1), respectively.
And step S30, dividing the numerical value converted by the user ID by the number of all the servers to obtain the remainder of the calculation result.
Specifically, the number of remainders of the calculation result is equal to the number of all servers; and classifying the user IDs according to the remainder, wherein the classified number is equal to the number of all servers, and each server corresponds to one class of users respectively.
For example, dividing the value a by the number B to obtain a remainder C of the calculation result, where the remainder C may be only one of (0, 1, 2...., B-1), and the remainder of dividing the value a by the number B is exactly B (the remainder is 0,1, 2.... B-1), the value a (converted from the user ID) is classified into B types according to the remainder, so that the users are classified into B types, and a total of B servers (not including the splitting server) are provided, and each server processes one type.
And step S40, the shunting server sends the request data packet to a server with the number equal to the remainder.
Specifically, the request data packets of the user IDs are classified according to the remainder, and the request data packets of the user IDs corresponding to each remainder are all sent to the same server for processing.
For example, the shunting server sends the request data packet to a server with the number equal to the remainder C, the remainder C (0, 1,2, B-1) is obtained by dividing the number a by the number B according to the numerical value a converted from the user ID, the data packets corresponding to the user ID are classified according to the value of the remainder, and the data packets of the user ID corresponding to each remainder are sent to the same server for processing, so that the data packets of the same user and the same classification are efficiently and stably sent to the same server for processing, the working states of all users do not need to be synchronized between the servers, and the data processing efficiency is improved.
