Problems solved by technology

The method based on Mac address division needs to plan the Mac address in advance, and requires the deployment location of the virtual machine to conform to the Mac address plan. Due to the limitation of the capacity of the Mac address segment, this method has scalability and flexibility problems.

Embodiment Construction

[0028] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0029] figure 1 A flowchart showing tenant division in an SDN network according to an embodiment of the present invention. Such as figure 1 As shown, the method mainly includes:

[0030] Step 100, receiving a virtual machine creation request sent by a tenant, where the virtual machine creation request includes tenant information.

[0031] The tenant information refers to the tenant ID. When creating a VM, you need to specify which tenant the VM belongs to. A tenant can be simply represented by a 24-digit number, and its value range can be 2 24 .

[0032] Step 102, creating a virtual machine and assigning a tenant ID to the virtual machine according to tenant information.

[0033]Before creating a virtual machine, you need to create a tenant (tenant) and assign a tenant ID (tenantID); when cre...

Abstract

The invention discloses a tenant dividing method in an SDN network, a device and an SDN network system. The method comprises steps of receiving a virtual machine creating request sent by a tenant, creating a virtual machine and distributing tenant identification according to tenant information contained in the virtual machine creating request, and informing a corresponding relationship between the virtual machine and the tenant identification to a software-defined network (SDN) controller to enable the SDN controller to manage the corresponding relationship between the virtual machine and the tenant identification. The tenant identification can be carried and interacted via OpenFlow message. In the provided method, device and system, tenant identification of any digits can be introduced; the controller can directly differentiate tenants via the tenant identification, so simplicity and effectiveness can be achieved, and demands of multi-tenants in a large-scale cloud data center can be met; the tenant information is carried via OpenFlow expansion messages and expansion fields, so a problem of tenant net overlapping due to flow space division can be reduced; and a flexible and high-efficient tenant network dividing method is achieved.

Description

technical field [0001] The present invention relates to the field of SDN, in particular to a tenant division method and device in an SDN network and an SDN network system. Background technique [0002] Virtualization technology has changed the provision mode of IT infrastructure, making traditional computing and storage facilities into operable resources, which can be elastically obtained by users on demand through the Internet, and dynamically scaled according to actual business needs. Static networks cannot effectively support the frequently changing networking requirements of cloud computing services. It is necessary to virtualize the network to improve the automatic service capability of the network. The traditional network virtualization method divides subnets, that is, tenant networks, through VLANs (Virtual Local Area Networks, virtual local area networks), and faces problems such as a limited number of VLANs and poor scalability. [0003] OpenFlow SDN (Software Defi...
