Claim:
1. A method for resource provisioning in software defined networking (SDN) architectures, the method comprising: receiving, by an inter-domain traffic engineering (TE) controller, border element information from multiple SDN controllers, the multiple SDN controllers being assigned to different domains of a network; computing, by the inter-domain TE controller, inter-domain allocation constraints in accordance with the border element information; and sending, by the inter-domain TE controller, the inter-domain allocation constraints to at least a first SDN controller in the multiple SDN controllers, the first SDN controller being assigned to a first domain of the network, wherein the first domain is connected to a second domain of the network via one or more inter-domain links, and wherein the inter-domain allocation constraints are configured to reserve resources on the one or more inter-domain links for inter-domain traffic originating from outside the first domain.
