The following table shows the elements which make up the VTN. In the VTN, a virtual network is constructed using virtual nodes (vBridge, vRouter) and virtual interfaces and links. It is possible to configure a network which has L2 and L3 transfer function, by connecting the virtual intrefaces made on virtual nodes via virtual links.
vBridge | The logical representation of L2 switch function. |
vRouter | The logical representation of router function. |
vTep | The logical representation of Tunnel End Point - TEP. |
vTunnel | The logical representation of Tunnel. |
vBypass | The logical representation of connectivity between controlled networks. |
Virtual interface | The representation of end point on the virtual node. |
Virtual Linkv(vLink) | The logical representation of L1 connectivity between virtual interfaces. |
The following figure shows an example of a constructed virtual network. VRT is defined as the vRouter, BR1 and BR2 are defined as vBridges. interfaces of the vRouter and vBridges are connected using vLinks.
