Description
Technical Field
The invention relates to a system and a method for collaborative communication of sticky real-time data.
Background
In numerous internet software of real-time cooperative communication, after Load Balance, namely LB, is realized between a client and an application server, because the client is randomly allocated to request to be connected to different servers by Load Balance, if some client communication requests need to maintain real-time cooperative communication and have bidirectional communication which can be polled for a long time like Websocket, the request of the client fails to find a corresponding server after Load Balance.
In large internet network architectures, since HTTP/S is a stateless protocol, session persistence is not considered when designing, many Web applications need to provide personalized user data during the session, e.g., keep a log of goods in a shopping cart, or in a chat session, and without session persistence, Web applications would have to maintain this information between multiple servers, which can be inefficient, especially for large networks.
In the prior art, the purpose of tracking and recording a fixed IP address of a server to realize persistent communication is used together with an IP _ hash upstream service, that is, when a client sends a request for the first time, a fixed IP address is injected into session communication such as session and sends a request to the fixed server, and finally, different request designations are identified by the IP address and allocated to corresponding servers.
However, the implementation scheme of using the fixed IP address of the server to store in a specific session for communication may cause data abnormality in communication, because in many cases, different browsers may use the same IP address to use a specific proxy or because the same similar IP address is forged, and the load balancing system may not recognize that the requests of different browsers come from the same IP address, which causes data abnormality. Moreover, the security of this method is very low, and the IP address of the server is easily exposed to the outside, thereby causing a great risk of attack or data leakage to the server.

The invention discloses a viscous real-time data cooperative communication system, which is characterized in that: the method comprises a load balancer and at least two application servers, wherein the application servers are respectively connected with the load balancer, the load balancer is connected with a plurality of external clients, when the client runs an application program corresponding to the application server, a sticky session is generated between the client and the load balancer, and long connection requests from different clients are automatically forwarded to the corresponding application servers through the load balancer within the session duration.
The sticky session is a cookie sticky session which is identified by the IP address of the injection client and the special user attribute.
The invention discloses a viscous real-time data cooperative communication method realized by the viscous real-time data cooperative communication system, which comprises the following steps:
A. configuring load balance of the application servers, and connecting the request load of each client to each application server through the load balance;

Detailed description of the invention
As shown in fig. 1, the sticky real-time data cooperative communication system in the present invention is characterized in that: the system comprises a load balancer 1 and at least two application servers 2, in the specific embodiment, the number of the application servers 2 is three, the application servers 2 are respectively in network connection with the load balancer 1, the load balancer 1 is respectively in network connection with three clients 3 of an external browser, an IOS mobile phone and an Android mobile phone, when the client 3 runs an application program corresponding to the application server 2, a sticky session is generated between the client 3 and the load balancer 1, and long connection requests from different clients 3 are automatically forwarded to the corresponding application servers 2 through the load balancer 1 within the session duration.
The sticky session is a cookie sticky session which is identified by the IP address of the injection client and the special user attribute.
In this embodiment, the load balancer 1 requires a cloud host with low configuration, high bandwidth, and good network performance, such as Nginx. The application server 2 is a standard application server of a cloud computing platform.
The invention discloses a viscous real-time data cooperative communication method realized by the viscous real-time data cooperative communication system, which comprises the following steps:
A. configuring the load balance of the application servers 2, and connecting the request load of each client 3 into each application server 2 through the load balancer 1;
B. setting an anti-proxy Websocket in a configuration file of the load balancer 1;
C. running an application program on the client 3 to generate a cookie sticky session which is injected with the IP address of the client and a special user attribute identifier;
D. setting a duration of the cookie sticky session;
E. and D, automatically forwarding the long connection request of the WebSocket from different clients to the corresponding application server 2 by the load balancer 1 within the duration set in the step D.
In step B, for setting an anti-proxy WebSocket in the configuration file of the load balancer 1, the following is a configuration based on Nginx:
http { server { list 80, server _ name app.vikadata.com, { location/{ proxy _ set _ header X-Forwarded-For $ proxy _ add _ X _ Forwarded _ For, # Start WebSockets service proxy _ http _ version 1.1, # proxy _ set _ header $ Host, # proxy _ http _ update, # proxy _ set _ header Connection "update" } stream nodes { # open sticky session IP _ hash based on IP address, server app01:80, server app02:80, server app03:80 } }
The invention is mainly used for protecting the viscous session load balance which utilizes the load balancer to realize high-safety and high-performance long-time communication, can be provided in real-time cooperative software and even large-scale internet architectures, provides an effective and accurate method for maintaining session information between a client (such as a web browser) and a server, and can help to reduce network workload.
Load balancing of sticky real-time collaborative data communication is a sticky session persistence process in which a load balancer creates an association between a client and a particular web server for the duration of a session (i.e., the time a particular IP spends on a web site). Using sticky sessions can help improve user experience and optimize the use of network resources. For sticky sessions, the load balancer typically assigns an identifying attribute to the user by publishing cookies or tracking details of its client (e.g., the client's IP address). Based on the tracking ID, the load balancer may then begin routing all requests for that user to a particular server for the duration of the session.
Session stickiness provides a number of benefits that can improve Web application performance:
one, minimize data exchange, with sticky sessions, servers in the network do not need to exchange session data, which is an expensive process when deployed on a large scale.
And secondly, the utilization rate of the RAM cache is increased, and the viscous session can more effectively utilize the RAM cache of the application program, so that the response speed is increased.
Thirdly, the security is high, and the transfer of the private information and the sensitive data in the communication process between the application program and the server can be better protected by using the sticky session
And fourthly, the flexibility is high, a sticky session with a specific valid time range can be sent out by the load balancer, the session does not have stickiness after the sticky session is expired, or the application program can generate a sticky session and follow the life cycle of the specified session (such as cookie life cycle), so that the user is ensured not to be sent to the server side after the local session is expired.
The invention is suitable for the field of sticky real-time cooperative data communication.
While the embodiments of the present invention have been described in terms of practical embodiments, they are not to be construed as limiting the meaning of the present invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
