Implementation method for one-to-multiple virtualization of OPENFlOW switch

Abstract

The invention discloses an implementation method for one-to-multiple virtualization of an OPENFlOW switch. The method comprises the following steps: utilizing BOOTROM to realize virtualization, conducting software version isolation, hardware virtualization and flow table virtualization to realize one-to-multiple virtualization of the OpenFlow switch. The implementation starts from a control surface, a management surface and a forwarding surface to implement virtualization function of the OpenFlow switch under an SDN (Software Defending Network) architecture and enable an SDN controller to monitor different OpenFlow switch nodes, and each independent device can be provided with different software versions, different OpenFlow secure channel connection, different OpenFlow flow tables, different configuration and different hardware resources, so that the network deployment and management are more flexible, and equipment control is safer.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for realizing one virtual multiple of an OPENFLOW switch. Background technique [0002] Network virtualization technology appeared very early, such as VLAN, VRF, etc. can be considered as the initial development of network virtualization technology. With the continuous evolution of technology, the development of network virtualization has two directions recognized by the industry, namely multiple virtual one and one virtual multiple. Network device one virtual multiple technology is to virtualize one physical device into two or more Multiple devices achieve more flexible network deployment and more reasonable network resource allocation. In essence, one virtual multi-device is to virtualize one device into multiple devices from the hardware resources. Each virtual device has its own hardware resources, including ports, memory, CPU, etc., not just port isolation or f...

Problems solved by technology

The one-virtual-multiple technology for network equipment is relatively difficult, and it is generally applied on high-end core equipment. However, with the development of SDN technology, OPENFLOW switches have been applied on a large scale. Currently, the one-virtual-multiple technology is basically implemented on traditional switches and uses traditional Virtualization technology cannot achieve complete virtualization on OPENFLOW switches. The patent of the present invention pays attention to this problem, and invented a method for realizing one virtual and multiple OPENFLOW switches, which integrates OPENFLOW switches from hardware resources, memory, software flow Tables, etc. are virtualized, starting from the control plane, management plane and forwarding plane, and realizing the function of OPENFLOW switch device virtualization under the SDN architecture
