Network node virtualization method

Abstract

The invention discloses a network node virtualization method. The method comprises the following steps that a virtualization mechanism VBN is used for binding a plurality of routers physically relatively centralized in the internet through a protocol to form a virtualization route switching node VBN externally provided with a single route, management and strategies; the VBN serves as an independent node and interacts routing information with other routers, and in the information interacting process, whether a node communicating with any node in the internet is a router or the VBN can not be judged. According to the network node virtualization method, in comparison with the prior art, on one hand, the VBN simplifies the topology complexity by aggregating a plurality of nodes; on the other hand, internal management of the VBN node is transparent to the outside, and the continuous service ability of the node can be further enhanced by sharing and flexible scheduling of multiple node sources.

Description

technical field [0001] The invention relates to the technical field of virtual networks, in particular to a network node virtualization method. Background technique [0002] As the Internet plays an increasingly important role in people's social life, how to ensure the safety and reliability of network services has received more and more attention. The focus of Internet technology research has gradually shifted from improving transmission and switching performance and enhancing QoS assurance to improving the controllability of network behavior and the survivability of network services. Especially in recent years, research on network security issues such as DDOS attack prevention and worm propagation, auditable network protocols, source address spoofing prevention, network security vulnerability analysis, and network survivability has gradually become a hot topic. The trusted network condenses the above content into a new research direction, and has become an important branc...

Problems solved by technology

However, the current trusted network research is facing a problem, that is, how to effectively support various trusted network services under the guidance of IP connectionless transmission mechanism and end-to-end design ideas, or the management and configuration of existing network infrastructure (such as routers) , Whether the fault discovery and recovery mechanism can meet the requirements of trusted network services
