Virtual routing device and routing method thereof

Abstract

The invention discloses a virtual routing device and a routing method thereof and relates to the technical field of an internet. The device disclosed by the invention comprises programmable hardware and a host, wherein the programmable hardware is used for achieving the data packet transmission function of a data plane; the host achieves the functions of a control plane and a management plane and comprises a host control unit and a virtual machine unit; the host control unit is used for initializing the programmable hardware and the virtual machine unit and periodically updating the items in the programmable hardware; and the virtual machine unit is used for achieving the functions of processing route protocols and processing data packets, generating and updating a route table and an ARP (Address Resolution Protocol) table in real time and providing the route table and the ARP table for the host control unit. In the invention, multiple parallel virtual networks can be simultaneously supported to operate different applications; the established different virtual networks can be completely isolated and are not mutually interfered; the forwarding rate is high and can reach the linear speed; and the device provided by the invention also has the characteristics of programmable depth, flexibility in configuration and good expansibility.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a virtual routing device and a routing 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 innovation of the Internet, but unfort...

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.
