Abstract
A method and system provide an information centric network with a software defined network based on an information centric networking protocol on top of a physical network based on the internet protocol. There are forwarding elements in the physical network and a controller in the software defined network for controlling the forwarding elements. A publicly routable network address per domain for outside data object requests of named data objects is announced via the information centric network, and upon a first packet of an object request being received by an ingress element of the information centric network, the first packet is forwarded to the controller. The controller determines an object source for the requested named data object, encodes a message id into a header of the packet and establishes a forwarding path to forward the packet and further packets to the determined object source.
