Abstract

The invention relates to the technical field of communication, in particular to virtualized router realized based on kvm and SRIOV and a method thereof. The system comprises a control plane, a forwarding plane and a management plane. According to the method for realizing virtualized router based on kvm and SRIOV and the method thereof, complete isolation of the control planes is realized based onkvm total virtualization, and different control planes can run different routing protocol stacks and also can run different underlying operating systems. The forwarding plane is realized by adopting an SR-IOV technology, and a network adapter is divided into a PF and a plurality of VFs. The forwarding plane adds a virtual interface to each virtual router to serve as a management network of the virtual router. A network bridge is established on the physical machine, and the PF and the management interface of each virtual machine router are added into the network bridge. Therefore, the mutual isolation function of the control planes of the virtualized router is achieved. The method can be applied to the field of communication where the virtualized router is located, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of communication, in particular, to realizing virtualized routing and a method thereof based on kvm and SRIOV. Background technique [0002] Due to the rapid development of the Internet, the speed of network links continues to increase. Traditional routers have high-speed data packet forwarding capabilities, but their flexibility and scalability are insufficient. In order to solve this problem, the virtualized router adopts a structure in which the data plane and the control plane are separated to enhance its flexibility and scalability while taking into account efficient data packet processing. [0003] With the continuous improvement of CPU processing power, the conflict between efficient data packet processing and flexible scalability of routers has been alleviated to some extent, but virtualized routers still face new problems such as how to support virtualization. The current virtualization technology ...
