A Design Method for Multidimensional Dual Space Networks

Abstract

The invention provides a method for designing a multidimensional double space network. An SDN system structure is used for forming an information processing space at a network edge part, a TCP / IP system structure is used for forming a packet transmission space at a core network part, and when the information processing space and the packet transmission space adopt unified global IP address planning, the method has the characteristics of : a separated optimized structure of the transmission space and the information processing space; hereditability of comprehensively inheriting the existing internet software and hardware resources; evolvability of defining a particular architecture to respond to the existing problems; integration capability of arranging different network system structures in the same framework; and when the information processing space adopts multidimensional global address planning, while the packet transmission space adopts global IP address planning, besides the characteristics of the method, the following characteristics are also available: large expansion of a network address space, and security and high efficiency of spatial isolation.

Description

technical field [0001] The invention belongs to the field of network communication, and specifically proposes a multi-dimensional dual-space method for constructing a new type of computer network, that is, a network design method that adopts an SDN architecture at the edge of the network and a TCP / IP architecture at the core network. Background technique [0002] At present, the Internet with the TCP / IP architecture is characterized by the thin waist of IP, which promotes the independent development of communication technology and network applications, and has achieved unprecedented success. However, the rapid development of the Internet exposes various insoluble difficulties in the TCP / IP architecture, which restricts people's increasing application requirements in terms of security, mobility, and service quality. In recent years, the future network research has been booming for more than 15 years, but there are not many practical results. Software Defined Networking (Soft...

Problems solved by technology

However, it manages and controls the network in a centralized manner, and is currently applied in a few enterprise networks such as data center networks or a limited number of switches, but it cannot complete the important task of reshaping the Internet

[0003] On the one hand, the Internet supports application innovation and can cover the whole world, while the OpenFlow network has few applications and a small coverage area; on the other hand, the OpenFlow network has strong control capabilities, while the Internet network layer is rigid and cannot provide solutions for security, mobility, QoS guarantees, etc. Provide solutions for problems
