OpenDaylight Virtual Tenant Network (VTN) is a set of technology components that provide a multi-tenant virtual network with the OpenDaylight controller. Traditionally, huge network investments and operating expenses are required because the network is configured as a silo for each dedicated system as silo. Various network appliances must be installed for each tenant and those boxes cannot be shared with others. Thus it’s a heavy work to design, implement and operate the entire complex network. The VTN addresses this problem by providing a logical abstraction models (ie. vRouter, vBridge, vTunnel) that enable the complete separation of logical plane from physical plane. The VTN also provides mapping between logical and physical plane. Thus Users can design and deploy any desired network without knowing the physical network topology or bandwidth restrictions. The VTN provide Northbound-API for its application so that applications don’t require knowing all the detail of physical plane’s complexity and can program the logical network via Northbound-API. This presentation will discuss the VTN more in details.
