Disclosed herein are a method for protecting data for information centric in-network computing and a system using the same. The method includes: preparing, at a computing node, a an encryption key pool that includes a security key for sharing a symmetric key used for encrypting result data according to a user's request and matching information; preparing, at an INC agent receiving the user's request, a synchronization key pool for sharing the security key through the matching information; and creating, by the computing node, a processor for executing output processing of the result data and allocating a security key to the processor based on the matching information of the encryption key pool when a security key exists. The security key is allocated to the computing node which is determined to perform the request in the INC agent.

A method for configuring a service function path (SFP) for a software defined network (SDN) based service function chain (SFC) may comprise configuring a SFC which is a set of ordered service functions (SFs) by reflecting requirements of a flow flowing into a network; generating a primary SFP that is a path through which the flow is to be actually transmitted in the network according to the SFC; generating a secondary SFP against an error of the primary SFP; and controlling a transmission path through which the flow is transmitted to be at least one of the primary SFP and the secondary SFP.

Apparatus and method for configuring service function path of service function chain based on software defined network

Provided is a distributed service function (SF) forwarding system that applies the corresponding service function chain (SFC) to traffic classified by a plurality of service network (SN) controller instances based on an SN overlay structure. Therefore, by selectively combining and executing necessary network functions (SFs) according to a path and traffic made up of defined component services, it is possible to dynamically configure and control one network service.

Distributed service function forwarding system

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.

System and method for virtual network-based distributed multi-domain routing control

An original packet flow mapping apparatus and method based on an overlay network. The original packet flow mapping apparatus may include a packet-in message receiver, a flow controller, an overlay tunnel controller, and an interface, whereby flows can be identified even in a physical network segment on which an overlay link is implemented and then the flow can be mapped to an original flow.

Overlay network-based original packet flow mapping apparatus and method therefor

A system and method for virtualizing SDN-based network monitoring. The system for includes: an information collector, a monitoring component, an information converter, and a resource allocator, in which a user-defined virtual monitor is included so that integrated monitoring may be performed, and expandability may be guaranteed to dynamically respond to a user's, demands.

System and method for virtualizing software defined network (SDN)-based network monitoring

An apparatus and method for generating a Software Defined Network (SDN)-based virtual network. The apparatus includes a network information generator and a virtual network generator, in which an SDN-based virtual network desired by a user may be generated efficiently by allocating physical resources to reflect various user demands.
