In the field of industrial internet, a set of high-performance identifier analysis system is needed for handle identifier analysis, so that a handle recursive analysis system needs to be separated from a handle identifier proxy cache system, the handle identifier recursive analysis system is dedicated to iterative analysis of identifiers, namely, the handle identifiers are iteratively inquired in servers at all levels to obtain analysis results of the handle identifiers, iterative flow generated by the iterative analysis is large, and efficiency is relatively low.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Session is a mechanism that can record the state of a user server, identifying the particular user server. The session identifier (session ID) and the session (session) are a (key, value) distributed data relationship, and the session identifier as a key value (key) can be mapped to a value (value), specific data in the session (session). There are many ways for a server to save a session (session), such as a memory, a database, a file, etc. Generally, in a large website, a special session server cluster is usually provided to store a user session, and session data is cached in a memory at this time.
An embodiment of the present invention provides a proxy forwarding method for handle identifiers, a flow of which is shown in fig. 1, and specifically includes:
step S1, searching whether the handle mark has a session identifier, if yes, executing step S2;
step S2, searching whether the session identifier has associated server information, if yes, executing step S3, and if no, executing step S4;
step S3, according to the server information, the handle mark is transmitted to the corresponding target recursion server;
step S4, the handle identifier is forwarded to a target recursive server selected from the plurality of recursive servers, and the server information of the selected target recursive server is stored in association with the session identifier.
Through the steps, the proxy forwarding of the handle identifier is divided into two cases. In the first case, when the handle id has a session id and the session id in the handle id has associated server information, the handle id can be forwarded to the corresponding target recursive server according to the server information. And the corresponding target recursive server is searched and selectively forwarded without the resolution modes such as IP address Hash query, so that the time delay of handle identifier resolution and cache query is greatly reduced, and the efficiency of handle identifier resolution is improved.
In the second case, when the handle identifier includes a session identifier and the session identifier does not have associated server information, through an analysis manner such as IP address hash query, it may be queried that one or more recursive servers may all be handle identifier forwarding servers, and it is necessary to select a more suitable target recursive server from the multiple recursive servers for the handle identifier, and the target recursive server information is associated with the session identifier in the handle identifier. Then, when the handle identifier is analyzed and queried, the handle can be directly forwarded to the target recursive server according to the target recursive server information associated with the session identifier in the handle identifier.
In the proxy forwarding method for handle identifiers according to this embodiment, in step S4, a target recursive server is selected from a plurality of recursive servers based on a load balancing algorithm.
The load balancing algorithm, as the name implies, means that requests or data are distributed to a plurality of operation units to be executed, and work tasks are completed together. The purpose of load balancing is to achieve the purposes of optimizing resource use, maximizing throughput rate, minimizing response time and avoiding the problem of single-point overload by scheduling clusters. In the present embodiment, the application of the load balancing algorithm is to select a preferred recursive server from a plurality of recursive servers as a target recursive server for handle identification. Depending on the preference, one or more factors such as the server's load capacity, current usage, geographic location, etc. may be considered.
Preferably, as shown in fig. 2, in this embodiment, the proxy forwarding method for handle identifier further includes, in step S1, if no, executing:
step S5, based on the load balancing algorithm, forwards the handle identifier to a target recursive server selected from the plurality of recursive servers.
Through the above steps, the proxy forwarding method for the handle identifier provided by the embodiment is divided into three cases for proxy forwarding of the handle identifier. The first case is that the handle identifier has a session identifier and the session identifier in the handle identifier has associated server information, and the second case is that the handle identifier has a session identifier and the session identifier does not have associated server information, and forwarding agent policies in the two cases are shown in fig. 1 and are not described herein again. In the third case, when the handle identifier does not have a session identifier, based on a load balancing algorithm, a more appropriate target recursive server can be efficiently selected and forwarded. Different forwarding strategies are adopted for the handle identifiers with or without the session identifiers, so that the resolution efficiency of the handle identifiers can be improved.
Preferably, in the embodiment of the present invention, the load balancing algorithm in the proxy forwarding method for handle identification is one of a round robin method, a random method, a source address hashing method, a weighted round robin method, a weighted random method, or a minimum connection number method.
The polling method is to distribute the requests to the back-end servers in turn in sequence, and treats each back-end server uniformly without concern for the actual number of connections of the servers and the current system load. The polling method can approximately equally forward the handle identification to each server, thereby realizing the even distribution and the load balance of the recursive server.
The random method randomly selects one of the servers to access according to the list size value of the back-end server through a random algorithm of the system. It can be known from the probability statistics theory that as the number of times that the client calls the server increases, the actual effect of the method is closer to the average allocation of the call amount to each server at the back end, that is, the polling result.
The source address hash rule is a numerical value obtained by obtaining the IP address of the client and calculating through a hash function, and the numerical value is used for carrying out modular operation on the size of the server list, so that the obtained result is the serial number of the server to be accessed by the client. And performing load balancing by adopting a source address hashing method, and mapping the client side with the same IP address to the same back-end server for access each time when the back-end server list is unchanged. The source address hashing method can realize that the recursive server to which the handle identification is forwarded is intelligently allocated according to the IP address of the client inquiring the handle identification.
And (3) a weighted polling method: different backend servers may not have the same configuration of machines and load on the current system, and therefore may not have the same pressure-resistant capabilities. Configuring a machine with high configuration and low load with higher weight to process more requests; while configuring low, high-load machines to assign them lower weights, reduce their system load, weighted polling handles this problem well and assigns requests to the back-end in order and by weight. The weighted round robin method may enable intelligent allocation of the recursive server to which the handle identity is forwarded based on the load capabilities of the recursive server itself.
The weighted random method is the same as the weighted polling method, and the weighted random method also distributes different weights according to the configuration of the back-end machine and the load of the system. Except that it is a random request to the back-end server by weight, not in order. The weighted polling method can intelligently allocate the recursive server to which the handle identifier is forwarded according to the weight of the recursive server, and the weight of the server can be defined by a user, so that the method has strong flexibility.
The algorithm of minimum number of connections is more flexible and intelligent, because the configuration of the back-end server is different, the processing of the request is slow or fast, it is according to the present connection situation of the back-end server, choose one server that the present backlog connection number is minimum among them to deal with the present request dynamically, raise the utilization efficiency of the back-end service as far as possible, will be responsible for and distribute to every server rationally.
The load balancing algorithm is based on different algorithms and has a performance emphasis, a user can select one or more algorithms according to the requirements of the user on the recursive server, the algorithms are only used for illustration, and the load balancing algorithm which can be adopted by the invention is not limited to the methods.
In the proxy forwarding method for handle identifiers provided in this embodiment, the server information is IP address information and port information of the selected target recursive server. The target recursive server can be accurately positioned according to the IP address and the port information, the IP address information and the port information are information with high use frequency in internet communication, and the IP address information such as 1.1.1.1 and the port information such as 80 have simpler information structures and are convenient to forward, cache and the like.
Referring to fig. 3, the present embodiment further provides a proxy forwarding server 1 for handle identification, including:
one or more processors 2; and
a memory 3, the memory 3 storing one or more programs configured for execution by the one or more processors 2, the one or more programs including instructions for:
step S1, searching whether the handle mark has a session identifier, if yes, executing step S2;
step S2, searching whether the session identifier has associated server information, if yes, executing step S3, and if no, executing step S4;
step S3, according to the server information, the handle mark is transmitted to the corresponding target recursion server;
step S4, the handle identifier is forwarded to a target recursive server selected from the plurality of recursive servers, and the server information of the selected target recursive server is stored in association with the session identifier.
Preferably, the proxy forwarding server 1 of the handle identification provided in this embodiment,
in step S4, a target recursive server is selected from the plurality of recursive servers based on a load balancing algorithm.
In step S1, if no, the following steps are executed:
step S5, based on the load balancing algorithm, forwards the handle identifier to a target recursive server selected from the plurality of recursive servers.
Preferably, the load balancing algorithm adopted by the proxy forwarding server 1 of the handle identifier provided in this embodiment is one of a polling method, a random method, a source address hashing method, a weighted polling method, a weighted random method, or a minimum connection number method.
The proxy forwarding server 1 of the handle identifier provided in the present embodiment has three cases for proxy forwarding of the handle identifier. In the first case, when the handle id has a session id and the session id in the handle id has associated server information, the handle id can be forwarded to the corresponding target recursive server according to the server information. And the corresponding target recursive server is searched and selectively forwarded without the resolution modes such as IP address Hash query, so that the time delay of handle identifier resolution and cache query is greatly reduced, and the efficiency of handle identifier resolution is improved. In the second case, when the handle identifier includes a session identifier and the session identifier does not have associated server information, through an analysis manner such as IP address hash query, it may be queried that one or more recursive servers may all serve as a handle identifier forwarding service, and it is necessary to select a more suitable target recursive server from the multiple recursive servers for the handle identifier, and the target recursive server information is associated with the session identifier in the handle identifier. After that, when the analysis query of the handle identifier is performed again, the handle can be directly forwarded to the target recursive server according to the target recursive server information associated with the session identifier in the handle identifier. In the third case, when the handle identifier does not have a session identifier, based on a load balancing algorithm, a more appropriate target recursive server can be efficiently selected and forwarded. The proxy forwarding server 1 of the handle identifier adopts different forwarding strategies for the presence or absence of the session identifier and the handle identifier of the server information related to the session identifier, so that the resolution efficiency of the handle identifier can be improved.
