Methods and systems for provisioning a virtual network in software defined networks

A virtual service provider controller comprising:

• a first virtual network operator interface adapted to receive, from a virtual network operator, a request for admission of a virtual network, the request including a specification of at least one resource required by the virtual network;
• a first infra-structure provider network controller interface adapted to transmit, to an infrastructure provider network controller, a request for resources determined in accordance with the received request for admission;
• a second infra-structure provider network controller interface adapted to receive a reply in response to the request for resources;
• and
• a second virtual network operator interface adapted to transmit, to the virtual network operator, an admission decision in accordance with a reply received in response to the request for resources.

A method of admitting a virtual network, the method comprising:

• receiving, from a virtual network operator, a request for admission of a virtual network, the request including an indication of geographic and temporal distribution of traffic, as defined for a plurality of regions and a plurality of time periods;
• determining that the traffic does not exceed predetermined capacity boundaries;
• and
• responsive to the determining, admitting the virtual network.
