Description
Technical Field
The invention relates to the technical field of internet, in particular to an intelligent integration network system and a communication method thereof.
Background
With the continuous expansion of internet user scale and the continuous extension of application field, the existing internet has presented the situations of "static state", "rigor", etc., and has exposed serious drawbacks in various aspects such as flexibility, resource utilization rate, manageability and controllability, etc., and it is difficult to support the urgent requirements of the high-speed development of the new internet + state on the increasingly complex, personalized and diversified network communication and service. It is widely accepted by those skilled in the art that the conventional "repair and mending" of the existing internet cannot fundamentally maintain its sustainable development. Therefore, the original design limitation is broken through, and a brand new next generation internet is absolutely necessary to be designed. Therefore, countries in europe, america and the like invest a large amount of capital in turn and start a series of important research projects, such as the GENI project, the FIA project, the FIRE project and the like, and aim to redesign a novel network system and related mechanisms thereof from different angles and requirements. Meanwhile, China also supports the Internet field greatly through a 973 plan, an 863 plan, a national significant research and development plan and the like in succession so as to construct a novel autonomous network in China and get rid of the embarrassing situation that the Internet development is limited by people.
In recent years, the research of the next generation information network has been developed unprecedentedly, and new ideas, ideas and technologies are emerging continuously, so that the redesign and optimization of the internet architecture from two layers of service provision and network transmission are attempted. Typical representative schemes include Network Function Virtualization (NFV), Information-Centric Networking (ICN), location-identity Networking (LISN), and Software-Defined Networking (SDN). In summary, in the service level, the NFV separates the network function from the hardware server in the form of software by using the virtualization technology, and completes the on-demand combination and the base layer network mapping of the virtual function by using the orchestrator of the management and control plane, thereby providing dynamic, efficient and diversified functional service supply for the user, and significantly improving the network resource utilization rate and the experience quality. The ICN carries out independent naming of decoupling of data contents from position information, realizes on-demand caching of flow data by a network and nearby acquisition of the required content data by a user by introducing a caching function in a router and adopting a hop-by-hop forwarding mode, and greatly reduces repeated flow in the network and transmission delay of data service. In a network layer, the LISN redesigns an interconnection and interworking mechanism between the terminal and the network by decoupling the identity and location semantics of the IP address, separating the address space of the core network and the access network, and introducing an identity-location identifier mapping system in a control plane, thereby comprehensively improving the security, mobility and expandability of the network. The SDN decouples the existing internet control and forwarding layers, and implements, through a logic centralized controller, that the underlying general forwarding device directs the traffic according to different policies applied by the upper layer, thereby greatly enhancing the flexibility and programmability of network transmission.
The disadvantages of the prior art are as follows: only a single layer of service provision or network transmission is focused on to improve and evolve an internet system architecture, global consideration is lacked, intelligent transfer and efficient cooperation of services and network resources cannot be realized, universality is poor, and different requirements of different industries on network communication and services are difficult to meet. Therefore, it is desirable to provide a new network system and communication method that organically integrates service provision and network transmission and meets the different requirements of different industries for network communication and services.
