Description

Network platform and method for realizing multi-point type application demand target

The present invention relates to the field of network service communication, and in particular to a network platform and a method for implementing a multi-point type application demand target.

Background technique

In the network society, with the deepening development of network applications, various new demands have emerged, showing new features and trends.

on the one hand. The application requirements of the "multi-point" type are becoming more and more prominent and have attracted widespread attention. A multi-point type application requirement refers to a requirement involving more than two software and hardware entities (including systems, sites, portals, platforms, etc.) that operate and manage independently at different locations in the network, and can be classified as "multi-point" type application requirements. Many "multi-point" type application requirements have been proposed, such as: "multi-point" applications: implementation based on multiple systems, websites, portals or platforms, data, information browsing queries, entry, collection, publishing, processing, aggregation , statistics, sharing or exchange, business processing, convergence and circulation, cross-enterprise business transfer, convergence and processing in the supply chain, cross-departmental collaborative or parallel approval of the government, and “one-off” of establishment, change or annual review Online reporting, etc.; Establish a comprehensive business application platform: Enterprise integrated business application platform based on various systems, websites, portals or platforms, intelligent transportation, emergency command, e-commerce operation platform, smart city or other large-scale comprehensive business applications Platform; Establish public service platform: government website group collaborative service, government public service platform, cross-hospital diagnosis and treatment platform, regional medical and health online public service platform, campus comprehensive service platform, "school-school communication" service platform, video monitoring platform, Cross-multiple video surveillance platform Frequency monitoring collaborative services platform; other forms of "multi-point" type applications: distributed control based on the detected Internet, multi cloud computing platform services or private cloud synergistic "triple play", was the field of networking. Many attempts have been made to solve the problem of multi-point type application requirements through the application of network application level, but the actual use effect is not satisfactory, and it also leads to many complexity problems.

on the other hand. In some occasions, especially in the case of small network bandwidth or high bandwidth demand, the granularity of control for communication transmission of network services is required to be smaller and smaller, and communication transmission control and management based on specific network services are required. For example, bandwidth, traffic, quality of service moderator QoS or service level management LSA, etc. for specific one or one network service and or one end user's network service communication. Another aspect. The above two aspects of the demand problem and other new demand issues, based on the number of communication networks or

IP networks are difficult to solve or effectively solve, requiring a service-based communication network and its network infrastructure.

Summary of the invention

The technical problem to be solved by the present invention is to provide a network platform and a method for realizing a multi-point type application demand target.

To solve the above technical problems, it is a prerequisite to deeply analyze the inherent structural requirements of the multi-point type application. In order to fully explain the technical solution and the principle of the present invention, before proposing the technical solution, the following first analyzes the multi-point type application requirements.

A requirement involving more than two systems, sites, gates, or platforms that operate and manage independently at different locations in the network can be classified as "multi-point" type application requirements. It has multi-level, multi-faceted features. The only core element of multi-point type application requirements is network services. The demand is concentrated after the network service is provided. When a "point" provides network services that cannot meet the demand, and other "points" provide services together, it is required. More "cooperative or collaborative services."

A network service is a process consisting of a set of basic operations such as computing, storage, and communication transfer in a computer network, rather than the hardware or program itself that provides the network service. Both the TCP/IP protocol and the OSI seven-layer model use a layer-by-layer service model, which stipulates that only the network services provided by the next layer correspond to the functions required by the upper layer. This unique point indicates that the functionality required for the requirement or requirement only corresponds directly to the network service and does not directly correspond to the specific device or software program. This is the basic principle that an existing network or an internet network must follow. Therefore, the satisfaction of the requirements is finally implemented into the network service. Users can obtain, provide, process, transfer and store data in the network by using various network services in the network or the Internet. Otherwise, the user must directly operate the different locations. The system to complete these. From the perspective of network users, although the content and expression of different requirements are different, they are all descriptions and descriptions of the functions of the required network services, and this direction is also unique. If there is no network service, even if there are more functions or data, it is “drinking the cake” for the user.

According to the layer-by-layer service mode of TCP/IP protocol and OSI seven-layer model, network services can divide four levels of network services: communication service, basic service, application service and user service.

Therefore, the technical problem to be solved by the present invention can be expressed as follows: Under the premise of autonomy of each point, how to utilize the network service provided by each "point", based on the network platform of the invention, realize new or more Demand function, solve the "multi-point" type application requirements and related multi-level technical problems in the network. The Technical issues have the following characteristics:

First, it belongs to the problem of the network service providing the later stage. For example, all of the above requirements are concentrated on the problems that the hardware and software entities can provide after the network service is actually provided. At present, software and hardware entities such as various systems, websites or network infrastructures can provide network services in the network or the Internet. The technical methods for software and hardware entities to provide network services have matured. The next problem to be solved is the use of There are new service requirements for network service resources, including the above multi-point type application issues, which require new network service-oriented requirements implementation methods, such as dynamic collaboration of network services, dynamic aggregation, proactive provisioning, accurate provisioning, and dynamics. Basic network-oriented service methods such as aggregation and multi-point collaborative services, rather than the technical methods of hardware and software entities that allow software and hardware entities to provide network services.

Second, the problem can only be solved during the communication process. Such methods can only be provided by the software and hardware entities in the communication process from the network service to the network service to the service object, and need to be automatically completed in the communication process, but the existing IP network, internet, network communication equipment, network control The management system or network infrastructure does not include the above functional representations and support functions, so the next generation network technology and network infrastructure are required for IP services, Internet services, network communication devices, network control management systems or network infrastructures for network service communication.

Third, new ways of providing network services are needed. From the application requirements of the "multi-point" type, it can be seen that the network service provision method is required, for multiple points in the network, that is, all reachable network nodes and access devices, rather than for a single hardware and software entity. In terms of. For example, it provides a way for dynamic coordination, dynamic aggregation, proactive provisioning, and accurate provisioning for individual end users.

Fourth, it is necessary to adopt a cross-multi-point unified control management mode based on the premise of "autonomy based on each point" in the network. In the case of "multi-point" type of application requirements, factors such as legal, management, system and technology are determined. Each system, each website, each network infrastructure, and each network communication device are controlled by themselves. It is a reality that human beings cannot change. However, when it comes to solving the problem of "multi-point" type, it needs a unified control management mechanism across multiple points. This requires a multi-point unified control management based on the premise of "self-point autonomy". mode.

Fifth, a new network protocol is needed. IP network or internet protocol, a protocol model of "best effort forward" packets, does not contain or have the above-mentioned network service-oriented methodology and its corresponding control management model in the communication process. Communication protocol model without network service, its Quality is still a data communication network, not a service communication network or a service-oriented communication network required to solve the above-mentioned demand problems.

Sixth, it has the characteristics of multi-level and multi-faceted superposition. The above-mentioned problems including multi-point type application requirements are superposed by multiple layers and multiple aspects of network communication services, basic services, application services, user services, control management, and communication protocols. The new network infrastructure provides a total solution, otherwise only solving some of the above problems will not solve the final problem.
