下面为大家整理一篇优秀的essay代写范文- Future network architecture，供大家参考学习，这篇论文讨论了未来网络体系架构。最初的网络随着技术的进步，已经渐渐发展为商业网络，在社会生产、生活活动中普及，并受到广泛的欢迎与认可，成为社会发展过程中不可或缺的一部分。但是由于社会发展速度的加快，技术生命周期越来越短，若想使网络能够不断适应变化发展的社会环境，就必须对未来网络体系架构的发展做出必要的创新与调整。未来网络体系架构应当具备更多的功能，以满足现实需要。

Initial network mainly as academic network, with the progress of technology, it has gradually developed into commercial network, spread in the social production and living activities, and was widely welcomed and recognized, to become an integral part of social development process. But because of social development, rapid technology life cycle is more and more short, if want to make the development of the network is able to adapt to the constantly changing social environment, must be in the future the development of network architecture to make the necessary innovation and adjustment. All countries have studied the future network architecture, and the United States, Japan, the European Union and other countries have formulated the framework development plan, which China should attach importance to. It is of great practical significance to explore this issue.

Software defined network can also be called SDN, the model want to be able to break through the traditional framework of distributed constraint, the data plane out in the control plane, make software defined network, in this model, the flexibility of network and virtual sex will improve greatly, and its design cost can be effectively reduced. Numerical control separation processing can make more concentrated management view, at the same time help abstract network facilities resources at the bottom, so it can become a virtual resources, provide necessary support for the top service and application, eventually improve the controllability and flexibility of the system. The essence of software definition network is three points, one is control plane programmable; Second, the interface is open; Third, logical concentration. Key technologies include architecture extensibility technology, network control and technology, and interactive protocol technology.

Information center network architecture can be called the ICN, the United States and the European Union the first study to this framework, the current research focus for the network/information center named data network architecture, the basis for the current IP network used by the hourglass model, different IP is replaced by the content block. The architecture involves a number of key technologies, such as naming mechanism technology, mobility technology, routing and forwarding mechanism technology, caching strategies, and transmission strategies. Since the structure is still in the initial stage of research, there are still more detailed technical problems, which should be analyzed and discussed in depth in the future.

The current key network models include mobile network model, cloud network model, optional network model, etc. Specifically, the first is the mobile network model. In this model architecture, mobility will become one of the basic attributes of the architecture, and its trust mechanism and security mechanism will be improved. Followed by cloud network model structure, its formation is dependent on the network management technology and virtualization technology, the system of resource transport, storage, calculation, analysis and so on work can be carried out in accordance with the actual demand of management and control; Finally is optional network model, because the network can be used more widely, so the network demand also shows the characteristics of the diversification of the strong, the network must strengthen the functional design, improve the comprehensiveness and reliability of function, the optional model is the model conform to this trend, allows users to choose their services.

This model combines the software to define the advantage of network, network and information center with strong comprehensive, practical and controllability, effective for transmission, storage, and network resources calculation processing, such as play a huge advantage in solving the problem of network, including green energy saving, perceived, mobility, security, controllable tube, a variety of problems such as extensibility, reconfigurable.

Future network architecture is a kind of new architecture, the core of its creation significance is not limited to the current Internet architecture patterns and constraints, but this architecture is not directly put into use, its deployment is the evolution type, namely the architecture innovation step by step. Due to network users more and more, its access application also tens of millions, and the network architecture of the future must be able to meet the demand of large-scale users, to ensure that the original application and network nodes can be directly communication network architecture in the future. When building a new architecture, you should set up the necessary facilities at the old and new boundary points to ensure that different versions of the underlying communication protocol can be compatible and gradually deployed to a large scale from a small scale.

Traditional Internet taken from end to end model, this model has been unable to adapt to social development needs, the future network architecture should be taken to the user, data and content for the center mode. Based on this characteristic, design rules must also changes, should develop in the direction of the simple open architecture form, which can improve network use broad, easy open design principle is the important foundation of sustainable development network.

Interruption of self management, mobility, tolerance, security is the basis of future network shall meet the function, the current many architecture research and discussion on a certain function, but a single powerful function and can not fundamentally promote the improvement of the future network architecture and development, how to meet the needs of embedded network security, enhance comprehensive network function and reliability are the focus of future research and the key.

Involves the interests of the subject in network architecture, including the data owner, application service and Internet service providers, government, users, etc., in order to effectively regulate and balance the interests of the parties, shall be set up in the future network architecture has the flexibility and extensibility interface, to ensure the effective implementation of the law, policy and interaction, to realize the economic benefit and social benefit and win-win.

In previous studies, Internet development has focused on improving the diversity of services, both on YouTube and Facebook. With the increase of Internet traffic services, people have put forward higher demands on service quality and efficiency, so the enhancement of natural service distribution capacity has become the main trend of the future network development. Telecom operators shall provide necessary distribution service for providers, to ensure that the custom application and lodge, replication, strong security and fault tolerance, load balancing, mobility and other requirements are met.

Application is an important driving force for network development, such as telephone network and world wide web technology. These applications have promoted the large-scale and sustainable development of the network in a certain period of time. The optimum and compatibility of the system will be greatly enhanced when the application with the driving significance is produced. So network architecture in the future, should attach importance to research and design on the application of the new, constantly optimize the network, enhance the further development of network and use the new application, it is very necessary and important.

At present, all future network architecture researches are based on original research. Although this research can achieve certain results, innovation and breakthrough are not strong. In order to achieve the effective integration and utilization of resources, should actively building a network experiment platform, ensure that resources can be Shared on the experiment platform of virtualization implementation, then the resources for effective integration, guarantee to make full use of its advantages.

The role of network in People's Daily life, work is not to be ignored, but social development faster and faster, the people also put forward more and newer demands for network, countries should pay attention to the future trend of network architecture, and strengthen technology innovation, make the network to provide better service, satisfy people growing and changing needs. At the present stage of research in the future network architecture more achievements, including the definition of software network, information center, network and so on a variety of models, in the future study, the future network architecture should have more features, to meet the needs of the reality.
