Abstract
A network system is connected to a first physical network comprising: a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service and to a second physical network including at least one apparatus for receiving data from the first and the second data transmission nodes, and constructs a virtual network for each service between the first and the second physical networks.
Claims12
A network system, connected to a first physical network comprising:
- a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service;
- and a second physical network including at least one apparatus for receiving data from the first and the second data transmission nodes,
- the network system constructing a virtual network between the first and the second physical networks for each service.
A control apparatus, connected to a first edge node provided on a boundary with a first physical network comprising:
- a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service and to a second edge node provided on a boundary with a second physical network including at least one apparatus for receiving data from the first and the second data transmission nodes,
- the control apparatus comprising means for controlling the first and the second edge nodes and constructing a virtual network for each service between the first and the second physical networks.
A method for constructing a virtual network comprising:
- causing a control apparatus, which is connected to a first edge node provided on a boundary with a first physical network including a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service and to a second edge node provided on a boundary with a second physical network including at least one apparatus, to receive data from the first and the second data transmission nodes receive setting information for constructing a virtual network for each service between the first and the second physical networks;
- and
- causing the control apparatus to control the first and the second edge nodes and to construct a virtual network for each of the services on the basis of the setting information.
A non-transitory computer-readable recording medium storing thereon a program, having a computer connected to a first edge node provided on a boundary with a first physical network comprising:
- a first data transmission node that transmits data used for a first service and a second data transmission node that transmits data used for a second service and to a second edge node provided on a boundary with a second physical network including at least one apparatus for receiving data from the first and the second data transmission nodes execute:
- a process of receiving setting information for constructing a virtual network for each service between the first and the second physical networks;
- and
- a process of controlling the first and the second edge nodes and constructing a virtual network for each of the services on the basis of the setting information.
