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

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.

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.

A system for managing customized SLA monitoring for providing a customized SLA monitoring service is linked with an external system to receive an external index order for a customer line subscribed in the service. The system reflects demands of the customer included in the external index order on SLA management data to update the SLA management data. Further, the system uses the updated SLA management data to determine whether to monitor with the external system and the customer line according to the result of the determination.

System and method for managing customized service level agreement monitoring

A communication server in cooperation with a telematics center receives a result message for condition guidance service selection result information from the telematics center to control a driver terminal according to traveling condition recognition of a vehicle, stores a driver terminal number, call control request information during traveling, and condition notice information during traveling included in the result message, sets a condition guidance service, and controls call connection with a call connection attempting terminal for attempting a call connection to the driver terminal according to a type of the result message.
