Description
Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for distributed dynamic adjustment of long connection service based on the Internet of things.
Background
Generally, in order to solve the technical problem that load balancing needs to be partially performed manually in an internet of things (IOT) system, most internet of things systems rely on java development, a huge dependency package of java on system traffic and high load on system memory and cpu. The operating environment of the distributed system has the following heterogeneity (namely, diversity and difference exist): network, computer hardware, operating systems, programming languages, software implementations performed by different developers. The middleware is a way to solve the heterogeneity, and the middleware refers to a software layer, which provides a programming abstraction and shields the heterogeneity of an underlying network, computer hardware, an operating system and a programming language. The distributed system can effectively and efficiently operate on different scales, most of the services of the Internet of things are realized by manually adjusting the load through operation and maintenance personnel, namely, after the service performance does not meet the production requirement, a new node service is started to support normal operation of services, and the current market mostly adopts java spring closed whole barrel to realize a load balancing and dynamic capacity expansion strategy.
And (3) load balancing strategy:
（1）Random：
weighting randomly, and setting random probability according to weight;
the probability of collision on one section is high, but the larger the call quantity is, the more uniform the distribution is, and the weight is used according to the probability and then is more uniform, thereby being beneficial to dynamically adjusting the weight of a provider;
the disadvantages are as follows: there is a problem with slow provider accumulation of requests, e.g., the second machine is slow but not hanging, getting stuck when the request is tuned to the second machine, and all requests get stuck on the second machine over time.
（2）RoundRobin：
Weighted polling, setting a polling ratio according to the weight after the convention, and circularly calling nodes;
the disadvantages are that: there is also the problem of slow provider accumulation requests.
For this, consul is optimized by using a smooth weighted polling algorithm of nginnx, and the calling process can be abstracted as the following table 1:
TABLE 1
| Pre-wheel sum weight | The winner in this round | Aggregate weight | Weight after round (winner minus aggregate weight) |
| Starting wheel | \ | \ | A(0), B(0), C(0) |
| A(3), B(2), C(1) | A | 6 | A(-3), B(2), C(1) |
| A(0), B(4), C(2) | B | 6 | A(0), B(-2), C(2) |
| A(3), B(0), C(3) | A | 6 | A(-3), B(0), C(3) |
| A(0), B(2), C(4) | C | 6 | A(0), B(2), C(-2) |
| A(3), B(4), C(-1) | B | 6 | A(3), B(-2), C(-1) |
| A(6), B(0), C(0) | A | 6 | A(0), B(0), C(0) |
It is found that after the turn of the summation weight (3 +2+ 1), the loop returns to the starting point, the node flow is smooth in the whole process, and even in a short time period, the probability is distributed as expected.
This algorithm may be used with confidence if the user has a need for weighted polling.
（3）LeastActive：
The least weighted active call is preferred, the lower the active number is, the more preferred the call is, and the weighted random operation is carried out on the same active number. The active number refers to the counting difference before and after calling (aiming at a specific provider, namely the request sending number-response returning number), and represents the task accumulation amount of the specific provider, and the lower the active number is, the stronger the processing capacity of the provider is;
having slower providers receive fewer requests because the slower providers will have a greater difference in count before and after invocation; in contrast, the more powerful the node, the more requests it processes.
It should be particularly noted that consul supports the raft algorithm, enabling a smooth implementation of a highly available registry.
The GRPC (Google Remote Procedure Call) advantages are as follows:
HTTP/2 provides mechanisms for connection multiplexing, bi-directional streaming, server push, request priority, header compression, etc. Bandwidth can be saved, TCP link times can be reduced, a CPU can be saved, the mobile device can be helped to prolong the service life of a battery, and the like. The protocol design of the GRPC uses the existing semantics of HTTP2, the data of the request and the response are sent by using HTTP Body, and other control information is represented by Header.
GRPC defines services using ProtoBuf, a data serialization protocol developed by Google (similar to XML, JSON, hessian). The ProtoBuf can serialize data and can be widely applied to the aspects of data storage, communication protocols and the like. The compression and transmission efficiency is high, the grammar is simple, and the expressive force is strong.
GRPC supports multiple languages (C, C + +, python, PHP, nodejs, C #, objective-C, golang, java), and can automatically generate client and server function libraries based on languages. Versions of other languages, among which GRPC supports C, C + +, node. Js, python, ruby, objective-C, PHP, and C #, are actively under development, GRPC-Java has been provided.
The proto file generates the target code, and data transmission is compressed, so that bandwidth pressure is effectively saved. Serialization and deserialization are carried out on the data classes directly in the application program, and formats such as xml and json do not need to be analyzed and mapped.

Detailed Description
Reference will now be made in detail to the embodiments of the present invention, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout.
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
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. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for dynamically adjusting a long connection service in a distributed manner based on the internet of things according to the present invention.
A method for distributed dynamic adjustment of long connection services based on the internet of things, the method comprising:
s1: a protoc protocol is defined by a user side, a corresponding user side code is generated according to the protoc protocol, and after the user side sends the user side code to a Nginx server side through the Internet of things, the user side obtains a long connection address related to the Nginx server side.
In one embodiment, the user terminal may be a user server. First, a protoc protocol is defined by a user end, for example, a rule, a standard or a convention established by the protoc protocol for data exchange in a network (which may be regarded as an internet of things). The protocol is used for communication between entities in software in different systems, servers or various electronic devices. When two entities are to communicate, the protocols must be composed of the same language, and for the communication content (which can be regarded as client code), how to communicate, the object communication and when to communicate, certain regulations must be adhered to, and these regulations are the protocols. Or simply a set of rules that control the exchange of data between more than two entities. In an electronic communication connection, each of the different layers has a specific protocol. Data exchange at both the hardware device level and the application level has its own protocol. In the Open System Interconnection (OSI) standard model, each layer may include one to two protocols, and both terminals of the electronic device that communicate must be able to recognize and comply with the protocols. Additionally, protocols are often described in terms of industry or international standards. The Nginx server can be implemented by software or a server, wherein Nginx is a high-performance HTTP and reverse proxy web server and also provides IMAP/POP3/SMTP service. And the user side acquires the long connection address related to the Nginx server side according to the user side code. Regarding the address applied to the long connection, the HTTP long connection means that after a TCP (Transmission Control Protocol) connection is established, the transport layer connection is not released any more, and the application layer is repeatedly used.
S2: and the Nginx server side realizes proxy forwarding configuration on the gateway server side through the long connection address.
In an embodiment, after the nginnx server receives the client code generated by the client through the defined protocol, the nginnx server further performs proxy forwarding configuration on the gateway server from the client code.
S3: and the gateway server performs policy management related to service connection allocation on the service server through a service registration center of the consul cluster terminal according to the proxy forwarding configuration.
In an embodiment, the Consul cluster is an open source tool for implementing Service discovery and configuration of the distributed system, and isolation between a Service provider (which may be regarded as a Service server) and a Service consumer (which may be regarded as a client) can be implemented, for example, the Service provider (Goods Service) registers itself in a Service registry of the Consul cluster, and registration information is ServiceName + ip/port, so that the Service consumer only needs to know the ServiceName to know the ip + port of the corresponding Service, thereby performing access and/or registration. For example, the policy management of service connection allocation may be regarded as a policy management that diversifies the way in which multiple services are connected to multiple intelligent appliances, so as to increase flexibility, and it is not possible that one of the multiple intelligent appliances loses network connection, and then other intelligent appliances also lose network connection.
S4: and the gateway server distributes a plurality of service connection modes through a distributed dynamic adjustment long connection service mode by combining with the corresponding policy management so as to realize the policy management of the connection number of the gateway server to the plurality of service connection modes.
In an embodiment, a gateway service end combines corresponding policy management, and allocates a plurality of service connection modes (for example, electronic devices 1, 3, and 5 in a first group are connected or electronic devices 2, 4, 6, and 8 in a second group are connected) by a policy management method according to a plurality of variable factors (which may be considered as variable factors for connecting networks according to different electronic devices or at different times) of the policy management, so as to implement policy management of the number of connections of the gateway service end to the plurality of service connection modes, for example, the number of connections of the electronic devices in the first group is 3 by policy management, the number of connections of the electronic devices in the second group is 4 by policy management, and the number of connections of the plurality of service connection modes managed by policy is not limited by a specific number of connections. The invention is flexible and convenient in application through a plurality of service connection modes managed by strategies, can adopt dynamic real-time updating modes such as gray level release and the like, and meets the requirements of high availability of services and high difficulty in finishing complex services.
Referring to fig. 1 and fig. 2, fig. 1 is a flowchart illustrating another method for dynamically adjusting a long connection service in a distributed manner based on the internet of things according to the present invention. Please refer to fig. 1 for S1-4, which are not repeated herein.
After the S4 allocating, by the gateway server, a plurality of service connection modes through a distributed dynamic adjustment long connection service manner in combination with the corresponding policy management to implement the policy management of the number of connections of the gateway server to the plurality of service connection modes, the method includes:
s5: the gateway server side performs the strategy management of starting and closing in a distributed dynamic adjustment long connection service mode through a threshold value obtained by a driving code of a docker application engine in the gateway server side according to the connection number of the plurality of service connection modes;
and when the connection number of the service connection modes does not reach a preset range from the threshold, the strategy management of starting and closing is not performed through the distributed dynamic adjustment long connection service mode.
In an embodiment, the docker application engine may enable developers to package their applications and dependencies into a portable image, and then distribute the portable image to any electronic device of the popular Linux or Windows operating system to implement virtualization through driver code, and further calculate a threshold value for obtaining the connection number of the multiple service connection modes, for example, the threshold value for obtaining the connection number of the first service connection mode is (for example, 10). When the connection number (for example, 7) of the first service connection mode does not reach the preset range (for example, 8) of the distance threshold, the policy management of starting and closing is not performed through the distributed dynamic adjustment long connection service mode, in other words, the connection number of the first service connection mode still has a space for adding other connectable electronic devices, so the policy management of the distributed dynamic adjustment long connection service mode is not performed.
After the S4 allocating, by the gateway server, a plurality of service connection modes through a distributed dynamic adjustment long connection service mode in combination with the corresponding policy management to implement the policy management of the number of connections of the gateway server to the plurality of service connection modes, the method includes:
when the connection number of the service connection modes reaches a preset range from the threshold value, performing the strategy management of starting and closing through the distributed dynamic adjustment long connection service mode;
the strategy management executed by the gateway server is to close the prior business service information and start a new business service code to be sent to the business server;
s6: and the service server side sends the new service code to a service registration center of the consul cluster side for registration.
In one embodiment, for example, the threshold for the acquisition of the number of connections for the second service connection mode is (e.g., 12). When the connection number (for example, 10) of the second service connection mode reaches a preset range (for example, 10) of the distance threshold, the policy management of starting and closing is performed by the distributed dynamic adjustment long connection service mode, in other words, the connection number of the second service connection mode does not have a space into which other electronic devices can be connected, so that the policy management of the distributed dynamic adjustment long connection service mode is performed. And the updated strategy management executed by the gateway server side is to further start a new service code after closing the previous service information and send the new service code to the service server side. And the service server side sends the new service code to a service registration center of the consul cluster side for registration through the updated policy management.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a flowchart of another method for dynamically adjusting a long connection service in a distributed manner based on the internet of things according to the present invention. Please refer to the embodiment description of fig. 1-2 for S1-2 and S5-6, which will not be described herein.
In S3, the gateway server performs policy management associated with service connection allocation to the service server through a service registry of the consul cluster, where the method includes:
s31: the client and/or the gateway server modify the policy management associated with load balancing in a configurable manner.
In one embodiment, the load balancing proposed by the present invention provides an inexpensive, effective and transparent method to expand the bandwidth of network devices and servers, increase throughput, enhance network data processing capability, and improve the flexibility and availability of the network. And when the number of connections in the service connection mode reaches the preset range of the distance threshold, the ue and/or the gateway server modify the policy management associated with load balancing in a configurable manner, in other words, the ue may modify the policy management associated with load balancing in a manual or automatic manner, and the gateway server may modify the policy management associated with load balancing in a manual or automatic manner.
In S4, the gateway server allocates a plurality of service connection modes by a distributed dynamic adjustment of a long connection service manner in combination with the corresponding policy management, so as to implement the policy management of the number of connections of the gateway server to the plurality of service connection modes, where the method includes:
s41: and after the gateway server sets the connection quantity of the plurality of service connection modes through the service server, acquiring the connection quantity associated with any one of the plurality of service connection modes and transmitting the connection quantity to a Redis storage end for storage.
In an embodiment, the gateway server sets the connection number of a plurality of service connection modes (e.g., a first service connection mode and a second service connection mode) through the service server, respectively (e.g., the first service connection mode is 7, and the second service connection mode is 10). And after acquiring the connection quantity related to any one of the first service connection mode and the second service connection mode, respectively transmitting the connection quantity of the first service connection mode and the second service connection mode to a Redis storage terminal for storage. The invention develops a set of long-chain connection services with the dynamic scheduling load balance of the Internet of things based on nodejs completely and autonomously, improves the availability of the services and reduces the purchase cost of the server (which can be regarded as each server).
Referring to fig. 1-2 and fig. 4-5, fig. 4 is a specific architecture diagram of a distributed dynamic adjustment long connection service based on the internet of things according to the present invention, and fig. 5 is a specific service timing diagram of the distributed dynamic adjustment long connection service based on the internet of things according to the present invention. In fig. 4, the user side sends the user side code to the Nginx server side through the internet of things, the Nginx server side implements proxy forwarding configuration for the gateway server side through the long connection address, and the gateway server side performs policy management associated with service connection allocation for the service server side through a service registration center (GRPS) of the consul cluster side according to the proxy forwarding configuration. For example, the principle of GRPS (Google Remote Procedure Call), SAP (System Applications and Products in Data Processing) System RPC Call is simple, there are some C/S (Client/Server) systems similar to a three-layer architecture, and a Client program of a third party calls standard or custom functions inside the SAP through an interface, and obtains Data returned by the functions to process and display or print the Data. The dynamic long-link scheduling method based on nodejs + grpc + consul makes up for the technical weakness of nodejs in the direction of the Internet of things by using the nodejs light development language, improves the availability of services, and reduces the purchase cost of a server (which can be regarded as a server).
In fig. 5, S1 defines a protoc protocol for the user side, generates a corresponding user side code according to the protoc protocol, and after the user side sends the user side code to the Nginx server side through the internet of things, the user side obtains a long connection address associated with the Nginx server side; s2, the proxy forwarding configuration of the gateway server is realized by the Nginx server through a long connection address; s3, the gateway server performs policy management related to service connection allocation on the service server through a service registration center of a consul cluster terminal according to proxy forwarding configuration; s4, distributing a plurality of service connection modes by combining the gateway server with corresponding policy management through a distributed dynamic adjustment long connection service mode so as to realize policy management of the connection number of the gateway server to the plurality of service connection modes; s5, the gateway server performs strategy management of starting and closing by a distributed dynamic regulation long connection service mode through a driving code of a docker application engine in the gateway server according to a threshold value of the connection number of a plurality of service connection modes; and S6, the service server sends the new service code to a service registration center of the consul cluster end for registration.
