Description
Technical Field
The present invention relates to the field of wireless network communication technologies, and in particular, to a network convergence communication method, a gateway device, and a system.
Background
With the rapid development of the information revolution, the internet has become a new channel for information dissemination, a new space for production and life, a new engine for economic development and the like, and the network space has also become the fifth general war space after land, sea, air and day, and is the core influencing national security, social stability, economic development and cultural dissemination. However, various original design defects and deficiencies are shown in the internet technology development process, such as poor expandability, poor security and other problems, and communication requirements of future networks such as "high efficiency", "ubiquitous" and the like cannot be met. Therefore, network researchers have been engaged in developing future network architecture. For example, to solve The problem of insufficient network address space of The existing IPv4, The IETF (The Internet engineering task Force) designs an IPv6 protocol, which is called to allocate addresses for each sand worldwide. To solve the problem that IP represents both identity and address, i.e. identity and address binding, researchers have proposed LISP (identity Separation Protocol). In order to solve the problem of binding TCP/IP network resources with location, researchers have proposed NDN (Named Data Networking) as an Information-Centric Networking (ICN) which is a typical example. In order to solve the problem of TCP/IP Network control and forwarding binding, researchers have proposed SDN (Software Defined Network). It is worth mentioning that SINET (Smart Identifier NETwork, intelligent cooperative Identifier NETwork) proposed by NETwork researchers in China tries to comprehensively solve the problem of triple binding of the existing TCP/IP NETwork for the first time.
Since the future network paradigm is proposed, the theoretical architecture construction, prototype system verification and other important stages are carried out, and most of the future network paradigm is deployed on a certain scale in industrial internet, internet of things, internet of vehicles, military self-organizing network, even fifth generation mobile communication network (5G). It is anticipated that with the rapid development of internet technology, new network protocols will emerge endlessly, and the network protocols are interdependent and difficult to replace each other.
Therefore, a network protocol convergence communication method, a ubiquitous gateway device and a system which are compatible with various current network protocols and provide openness for any future network protocol, such as "encapsulation", "inheritance" and "polymorphism", are needed to meet the requirement of any future network protocol interconnection and interworking.
A first network architecture of a converged network in the prior art is a multi-network converged communication system, which includes: a converged communication console, a trunking network gateway, a cellular communication network gateway, a telephone network gateway, and a self-organizing network. The converged communication console comprises a plurality of communication interfaces; the cluster network gateway, the cellular communication network gateway, the telephone network gateway and the self-organizing network are respectively connected with the converged communication console through corresponding communication interfaces and are used for realizing interconnection and intercommunication among the cluster network, the cellular communication network, the telephone network and the self-organizing network. The technical scheme of the invention is used for fusing different systems and different protocol networks to realize interconnection.
The above-mentioned multi-network converged communication system in the prior art has the following disadvantages: the system only comprises a cluster network architecture, a cellular network architecture, a telephone network architecture and an ad hoc network architecture on one hand, and does not provide compatibility for other possible future network architectures and protocols. On the other hand, the gateway functions of the trunking network, the cellular network, the telephone network and the self-organizing network in the system are solid and rigid, namely, developers need to write codes in advance to customize each gateway function. This results in the need to customize multiple gateways to be compatible with different network protocols, and when a network protocol is changed in a certain access network, developers need to rewrite the code to implement the gateway of the network protocol, which is tedious in process and repetitive in work, and cannot be compatible with any network protocol with a universal gateway and support online automatic update.
The network architecture of the second kind of converged network in the prior art is: the converged network realizes the intercommunication between an Information Center Network (ICN) and a TCP/IP network. The network architecture of the converged network is as follows: compared with the existing fusion network which takes the ICN network as the backbone network, the fusion network provided by the embodiment of the invention has much smaller change on the TCP/IP network architecture in the existing application, so that the TCP/IP network architecture in the existing application can be utilized to realize the fusion of the ICN network and the TCP/IP network in a larger scale.
The above-mentioned fusion network for implementing the interworking between the Information Centric Networking (ICN) and the TCP/IP network in the prior art has the following disadvantages: the converged network only introduces a method for intercommunication and convergence of future network paradigm ICN and the current TCP/IP network, and cannot meet the requirements of multi-network protocols of future network multi-network systems. For example, the patent does not provide a method for interworking and convergence of a smart collaboration network (SINET) with the current TCP/IP network. In addition, the invention patent can not solve the problem of the intercommunication and fusion of the network protocol and the current TCP/IP network which may appear in the future.
