Abstract: A system for controlling a carrier virtual network is disclosed. The system includes at least one virtual network controller for controlling resources of a carrier virtual network based on customer request information received from a customer network controller, and at least one physical network controller for controlling resources of a carrier physical network based on a service profile received from the at least one virtual network controller. The at least one virtual network controller interworks with the at least one physical network controller in a one to one, one to N (N is an integer equal to or larger than 2), or N to one correspondence.

Abstract: A system for distributed multi-domain routing control includes two or more software-defined network (SDN) controllers and virtual routers. The two or more SDN controllers create virtual topology information by collecting information about switches under the control thereof, exchange network information about a different virtual network, as well as create a routing path from a source terminal to a destination cross switch or a routing path from the destination cross switch to a destination terminal based on location identification information of the destination terminal and/or the virtual topology information. Then, the virtual routers manage communication between the different virtual tenant networks or communication between each virtual tenant network and an external network.

Abstract: Disclosed herein a method and system for optimizing content removal from content store in NDN. The method includes: search the content store when receiving a request interest packet from a consumer; generating an optimization table when receiving the request interest packet; receiving first data corresponding to the request interest packet from a producer; storing the first data in the content store; setting an entry hit rate and a threshold; and deleting the stored first data based on the set entry hit rate and the set threshold.

Abstract: Disclosed herein is a system and method for validating data integrity and provenance in named data networking (NDN). For more efficient security in NDN, per-segment provenance and data integrity are verified by minimizing the number of signing operations regardless of the size of data using the attributes of a Merkle tree. Generation and validation of a manifest with per-segment provenance and integrity of a file is possible regardless of the size of the file, thereby reducing burden of computing.
