METHOD AND SYSTEM FOR PROVIDING AN INFORMATION CENTRIC NETWORK

摘要

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.

1. A method for providing an information centric network with a software defined network based on an information centric networking protocol on top of a physical network based on an internet protocol, comprising forwarding elements in the physical network and a controller in the software defined network for controlling the forwarding elements, the method comprising:
announcing a publicly routable network address per domain for outside data object requests of named data objects via the information centric network; forwarding a first packet of one of the object requests to the controller based upon the first packet being received by an ingress element of the information centric network; determining, by the controller, an object source for a requested named data object; encoding, by the controller, a message ID into the first packet; and establishing, by the controller, a forwarding path to forward the first packet and further packets to the determined object source.
