METHOD FOR PROVIDING OVERLAY NETWORK INTERWORKING WITH UNDERLAY NETWORK AND SYSTEM PERFORMING SAME
First Claim
1. A method for providing an overlay-based virtual network between data centers (DC) connected with a wide area network (WAN), by interworking with an underlay network, the method comprising:
- identifying, by a network virtualization authority (NVA), accessibility between a source tenant system (TS) connected to a first network virtualization edge (NVE) included in a first DC and a destination TS connected to a second NVE included in a second DC;
transferring, by the NVA, forwarding information obtained by interworking with the first NVE to the second NVE; and
configuring, by the NVA, a path by performing a tunneling procedure between the first NVE and the second NVE by using information on the WAN and a control command.

Abstract
A method and a system for providing an overlay network interworking with an underlay network are disclosed. The method for providing the overlay network interworking with the underlay network comprises a method for providing an overlay based virtual network between data centers (DC) connected with a wide area network (WAN), the method comprises the steps of: identifying accessibility between a source customer system connected to a first network virtualization device included in a first DC and an object customer system connected to a second virtualization device included in a second DC by a network virtualization management device; transferring forwarding information obtained by interworking with the first network virtualization device to the second virtualization device by the network virtualization management device; and configuring a path so as to perform a tunneling process between the first network virtualization device and the second network virtualization device using information on a WAN section and a control command by the network virtualization management device.

11. A method for providing an overlay-based virtual network between a first data center (DC) and a second DC connected with a wide area network (WAN) by interworking with an underlay network, the method comprising:
-
selecting, by a network virtualization authority (NVA), a path in the WAN based on information on the WAN which is received from a WAN controller controlling the WAN, and transferring information on the selected path to a first network virtualization edge (NVE) included in the first DC; and transferring, by the NVA, a control command for configuring an overlay network to a first DC controller controlling the first DC, a second DC controller controlling the second DC, and the WAN controller, through the selected path. - View Dependent Claims (12, 13, 14, 15)

16. A method for providing an overlay-based virtual network between data centers (DC) connected with a wide area network (WAN) by interworking with an underlay network, the method comprising:
-
receiving, by a first network virtualization edge (NVE), a control command for a tunneling procedure from a network virtualization authority (NVA); transferring, by the first NVE, a packet encapsulated base on the control command to a second NVE; and decapsulating, by the second NVE, the encapsulated packet, and configuring a path for configuring a virtual network with the first NVE, wherein the control command for the tunneling procedure is generated based on network control management information updated by using a path selected within the WAN based on information on the WAN which is received by the NVA from a WAN controller controlling the WAN. - View Dependent Claims (17)
