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
The present invention relates to virtual networking field, specifically a kind of network node virtual method.
Background technology
Along with the status of the Internet in people's social life is more and more important, how to ensure that the safe and reliable of network service is more and more paid close attention to.Also ensured to transfer to by raising transmission and switching performance, enhancing QoS gradually to the research emphasis of Internet technology and improve the aspect such as the controllability of network behavior, the survivability of network service.Particularly in recent years to network security problems such as DDOS attack strick precaution, worm propagations, auditable procotol, source address spoofing are taken precautions against, the research of network security vulnerabilities analysis and network survivability becomes focus gradually.Trustable network, by research direction new for condensed for foregoing one-tenth one, has become the important branch of Next Generation Internet research.But trustable network research at present faces a problem, namely under IP instructs without connection transfer mechanism and end-to-end design philosophy, how effectively support various trustable network service, can the management of network infrastructure (as router) in other words, configuration, fault discovery and Restoration Mechanism meet the requirement that trustable network is served.Virtual be in recent years study Internet field occur new technology, its thought is by the abstract shielding physics real-time performance details to bottom, by network-based control management be effectively separated with exchange with the forwarding of datum plane.Intel Virtualization Technology is that the Mechanism Design of trustable network provides wide space.Recent research shows, virtually not only has great importance to the research of Novel Internet architecture, test and deployment, also can improve its fault redundance, continue the ability of providing services on the Internet to the virtual of network element (as router).
Summary of the invention
Technical assignment of the present invention is to provide a kind of network node virtual method.
Technical assignment of the present invention realizes in the following manner, and the method step is as follows:
With virtualization mechanism VBN by the Internet physically multiple routers of Relatively centralized by protocol binding to together, form the virtual flow-line switching node VBN externally with single route, management and strategy; VBN is as an isolated node and the mutual routing iinformation of other routers, and in information interactive process, in the Internet, any node all cannot judge that the node communicated with is router or VBN.
Multiple routers of described physically Relatively centralized refer to have identical management and the router of routing policy.
Described virtual flow-line switching node VBN comprises virtual controlling plane and virtual data plane.
Described virtual controlling plane is responsible for the resource management of all control planes, by the processor of all control planes composition pool of processor structure, and flexible allocation resource according to demand.
Described virtual data plane is responsible for polymerization and the distribution of datum plane process resource and bandwidth resources.
Compared to the prior art, on the one hand, VBN simplifies topological complexity by the multiple node of polymerization to a kind of network node virtual method of the present invention; On the other hand, the management of VBN intra-node is externally transparent, and the shared and flexible dispatching of multiple node resource can strengthen the sustained serviceability of node further.

Accompanying drawing 2 is a kind of virtual schematic diagram of VBN of network node virtual method.
Embodiment
Embodiment 1:
This network node virtual method step is as follows:
With virtualization mechanism VBN (VirtualBigNode) by the Internet physically multiple routers of Relatively centralized by protocol binding to together, above-mentioned router has identical management and the router of routing policy, and after the binding of these routers, formation externally has the virtual flow-line switching node VBN of single route, management and strategy; VBN is as an isolated node and the mutual routing iinformation of other routers, and in information interactive process, in the Internet, any node all cannot judge that the node communicated with is router or VBN.
Embodiment 2:
This network node virtual method step is as follows:
With virtualization mechanism VBN (VirtualBigNode) by the Internet physically multiple routers of Relatively centralized by protocol binding to together, above-mentioned router has identical management and the router of routing policy, and after the binding of these routers, formation externally has the virtual flow-line switching node VBN of single route, management and strategy; VBN is as an isolated node and the mutual routing iinformation of other routers, and in information interactive process, in the Internet, any node all cannot judge that the node communicated with is router or VBN; Appeal virtual flow-line switching node VBN comprises virtual controlling plane and virtual data plane, and virtual controlling plane is responsible for the resource management of all control planes, by the processor of all control planes composition pool of processor structure, and flexible allocation resource according to demand; Virtual data plane is responsible for polymerization and the distribution of datum plane process resource and bandwidth resources.
Adopt above-mentioned network node virtual method, figure interior joint number can be reduced, therefore can reduce the complexity that problem is asked, separated.Such as router operation ospf protocol carries out the complexity of SPF router-level topology is O (n3), and storage complexity is O (n), and therefore VBN reduces by multi-router binding the expense that nodes n can reduce protocol processes.The complexity that such as router FIB stores again is O (m), and wherein m is the subnet number of the Internet.If VBN is bound by K router, obviously, the Internet internal subnet number that can make each VBN reduces at most K (K-1)/2 (the totally interconnected situation of all-router), at least reduces K-1 (all-router situation connected in series).Therefore VBN widespread deployment to solve the FIB Limits properties that faces of the Internet also tool have very great help.
By embodiment above, described those skilled in the art can be easy to realize the present invention.But should be appreciated that the present invention is not limited to above-mentioned several embodiments.On the basis of disclosed execution mode, described those skilled in the art can the different technical characteristic of combination in any, thus realizes different technical schemes.
