Description
Technical Field
The invention relates to the technical field of long connection, in particular to a long connection management system.

The nature and characteristics of the internet: "equal", "open", "interactive", "instant", "shared". The network cooperative manufacturing is a modern manufacturing mode which fully utilizes the network technology and the information technology which take the internet technology as the characteristics, realizes the cooperation of enterprise product design, manufacture, management, commerce and the like in a supply chain and among cross-supply chains and achieves the aim of maximum utilization of resources. The cooperative manufacturing is the core content of production modes such as intelligent manufacturing, cooperative commerce, network manufacturing, cloud manufacturing, global manufacturing and the like, emphasizes the cooperation among enterprises, breaks the time and space constraints, and enables the enterprises and the partners on the whole supply chain to share client, design, production and operation information through the internet. The traditional serial working mode is changed into a parallel working mode. Therefore, the time for bringing new products to the market is shortened to the maximum extent, the production period is shortened, the customer requirements are responded quickly, and the flexibility of design and production is improved. By means of process-oriented design, production-oriented design, cost-oriented design and design participation of suppliers, the design level and manufacturability of products are greatly improved, and the cost controllability is improved. The method is favorable for reducing the production and operation cost, improving the quality and improving the customer satisfaction.
The first layer is the interconnection of the production domains in the enterprises, realizes the interconnection of the applications and the equipment, and realizes the connection of the applications and the equipment; the second layer is to realize interconnection and intercommunication between supply and demand chains, and realize the symbiosis between enterprises through the business interconnection between upstream and downstream enterprises; and in the third aspect, the ecological interconnection of the industrial clusters realizes the horizontal and vertical connection of the whole industrial ecology. The partitioning relating to clouds in particular is as follows:
applications are interconnected with devices. Belonging to private cloud inside enterprise;
and (4) service interconnection. Belonging to a mixed cloud between enterprises on the upstream and downstream of a supply chain;
and (4) interconnection of industries. Belongs to the ecological interconnection of cross-supply chain and cross-industry clusters and is a public cloud.
The cloud and the edge establish connection, and can be abstracted into a scene shown in fig. 1.
The long and short connections are opposite. The definition for long and short connections is as follows:
long connection: after the connection is established, the connection is not actively disconnected, large data volume transmission and real-time data transmission are carried out, and bidirectional charging is possible.
Short connection: data is connected only when the data needs to be interacted, and one-way charging is possible due to one-time data requirement.
Of course, the charging model here is not the technical nature of a long or short connection, but depends on a specific pricing mechanism. The current problem of serious resource waste and credibility exists when a long connection is simply used.

Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
Example (b):
the introduction of the state machine and state transition characterization shown in fig. 2 for long connections is specifically described as follows:
the "active" state represents a frequent heartbeat mechanism, etc.;
the "inactive" state represents an infrequent heartbeat mechanism or short connection;
the "idle" state indicates connection release.
The "inactive" long connection includes, in addition to the short connection, an alternative mechanism as shown in fig. 3, which is used for an adaptive heartbeat control mechanism, such as sending heartbeat packets during the awake period and not sending heartbeat packets during the quiet period, so as to control the sending amount of heartbeat packets. It should be noted that, the state transition in fig. 2 may be controlled based on different timers, and the size of the timer is configurable; the awake, quiet, and cycle periods in fig. 3 are also configurable.
Specifically, the method comprises the following steps:
the admission control module controls new access based on input information such as load, and the like, and comprises a preemption mechanism, for example, when the load exceeds a certain threshold, new long connection is not allowed to be established, and the size of the admission control threshold can be configured. In addition to resource-based admission control, security-based access control is also included, such as attribute-based access control, role-based access control, task-based access control, and the like.
The load control module, as shown in fig. 5:
and (3) normal state: no load control is required and admission is possible.
Primary congestion: the system is stable, the resources are in shortage, the available resources left for new access are few, load reforming is needed, and an access space is reserved.
Overload congestion: the system is unstable, overload and call drop can occur, rapid overload control is needed, and the system load is reduced.
The long connection management scheme that may be taken is: when the load is in a normal area, long connection is adopted; when the load enters the congestion control area, part of the connections enter the 'inactive' state of the long connection (the connection can be selected based on the user priority or the service priority); when the load enters the overload control threshold area, the partial long connection can be released selectively, and the principle of selection is similar. The overload threshold and congestion threshold are configurable in size.
The traffic differentiation module, any service, needs to consider the quality of service, which is simply called QoS in communication and computer networks. Based on the QoS of the service, differentiated long connection management is carried out. For example, fig. 6 is a comparison of elastic traffic (fig. 6a) and deterministic traffic (fig. 6 b). Different connection management mechanisms can be triggered for elastic traffic and deterministic traffic, for example, for deterministic traffic, the "active" state of a long connection is used as much as possible, and for elastic traffic, a state migration mechanism of a long connection can be introduced.
The user differentiation module, similar to the service differentiation, considers the user differentiation based on the user attribute, such as for a high priority user, the priority of an "active" state using a long connection is higher, and a low priority user is preferentially selected in the state transition based on load control.
The big data analysis module is used for selecting business and user portraits by using big data technology in big data era, and the discovery of data-driven business attributes and safety gradually become trends. Based on the analysis of the popularity of big data, the long connection mechanism is controlled in a differentiation mode. From the results, it is common to the traffic differentiation and user differentiation modules, but not known in advance, but analyzed by the big data module. For example, long connections are preferred for "popular" traffic, and less so for "unpopular" traffic.
And the credibility measurement module is used for carrying out differentiation control on the long connection mechanism based on the credibility measurement of the connection. Credibility is differentiated, and needs to be quantified. It is measured in a mathematical sense, and the confidence level is expressed in terms of a confidence value or confidence level. For example, a long connection is preferred for a high level of confidence and a second for a low level of confidence.
Design principle of credible model: accuracy (Accuracy), Scalability (Scalability), Dynamic Adaptability (Dynamic Adaptability), Robustness (Robustness), Reliability (Reliability), and Incentive Mechanism (inclusive Mechanism).
The pricing mechanism module constructs pricing based on an economics theory, performs differentiated control on the long connection mechanism, and can refer to an economics and pricing model shown in fig. 7. For example, a long connection mechanism may be used preferentially for high bids and secondarily for low bids.
Each module is independent, namely can exist independently; how each module is used after being input into the block shown in fig. 4 depends on a specific scheme, for example, the color and the weight can reflect the preference of the table, and the judgment can be carried out only by the color judgment, only by the weight judgment, or by combining the weights of the color and the weight.
Those skilled in the art will appreciate that, in addition to implementing the systems, apparatus, and individual modules thereof provided by the present invention in purely computer readable program code, the same procedures can be implemented entirely by logically programming method steps into logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Therefore, the system, the apparatus, and the modules thereof provided by the present invention may be considered as a hardware component, and the modules included in the system, the apparatus, and the modules for implementing various programs may also be considered as structures in the hardware component; modules for performing various functions may also be considered to be both software programs for performing the methods and structures within hardware components.
