Communication method of programmable virtualized router based on NetFPGA

Abstract

The invention discloses a communication method of a programmable virtualized router based on NetFPGA. The communication method comprises the steps that virtualized software is installed on a host to acquire a plurality of virtualized containers, and routing protocol software is installed in each virtualized container to acquire a virtualized router; virtualized ethernet cards are set up inside each virtualized router, wherein the number of the virtualized ethernet cards is equal to the number of hardware network interfaces of bottom-layer NetFPGA; a software network bridge is arranged to bridge between the virtualized ethernet cards and the physical hardware network interfaces, each virtualized router receives a data package from a NetFPGA board card network interface through the virtualized ethernet cards and the software network bridge, routing information is acquired through the treatment of each virtualized router, the routing information is transmitted to a register of the NetFPGA through the virtualized ethernet cards and the software network bridge, and then the retransmission of the data package is achieved through the NetFPGA board card network interface and an outside network. Network communication of a plurality of programmable virtualized routers can be achieved through the software network bridge.

Description

technical field

[0001] The invention relates to the technical field of computer network virtualization technology and programmable router, in particular to a communication method of a programmable virtual router based on NetFPGA. Background technique

[0002] The Internet with ARPANET as the prototype and TCP / IP as the protocol stack has been developed for more than 40 years. During this period, the Internet has undergone earth-shaking changes. With the continuous development of the scale of Internet commercial applications, its application scope has far exceeded the original intention of the Internet design, and the existing TCP / IP architecture cannot solve the fundamental problems faced by the Internet such as scalability, dynamics, and security controllability. These problems force people to reconsider the design goals and concepts of the Internet, and study the architecture and mechanism of the future Internet.

[0003] Future network research aims to conduct theoretica...
