Control plane structure of virtual routing device and control method thereof

Abstract

The invention discloses a control plane structure of a virtual routing device and a control method thereof, and relates to the technical field of Internet. The control plane structure comprises a host control unit and a plurality of virtual machine units, wherein the host control unit is used for realizing user interaction and management and control over a data plane and the virtual machine units, and periodically updating a routing table and an address resolution protocol (ARP) table in the data plane; and the virtual machine unit is used for realizing a routing protocol processing function and a data packet processing function, generating and updating the routing table and the ARP table in real time, and providing the routing table and the ARP table for the host control unit. The virtual routing device comprises programmable hardware and a host, wherein the programmable hardware is used for realizing a data plane function. By the structure and the method, a proper routing protocol can be flexibly selected according to an application scenario and stably maintained, table entries can be updated in real time, the flexible configuration of the data plane can be realized, and accurate responses can be given to the needs of a user in real time.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a control plane structure of a virtual routing device and a control method thereof. Background technique [0002] In the process of emergence and development of the Internet in the past few decades, it has achieved remarkable success. Based on the Internet, there are more and more users, more and more applications, and more and more services. However, precisely because of the widespread nature of the Internet, it is becoming more and more inconsistent with the original design intention, and inherent disadvantages and new defects continue to emerge. Therefore, many scholars have joined in the research on the future Internet and produced a series of research results. However, most of the research results are based on the modification of the original Internet architecture, and have not effectively solved its inherent problems. Other research results involve radical innovatio...

AI Technical Summary

Problems solved by technology

In the past research results, there are two virtual router solutions: the first one is a software-based virtual router, which is characterized by flexible configuration and strong programmability, but the software virtual router has its insurmountable bottleneck: The forwarding rate is low, because its forwarding function is realized by software

The second solution is a hardware-based virtual router. Its biggest feature is its high forwarding rate, even up to wire speed. However, its flexibility and configurability are difficult to compare with software virtual routers.

In addition, the current research results on hardware virtual routers also have certain defects in isolation, and complete isolation cannot be achieved between each plane.
