SYSTEM FOR SUPPORTING MULTI-TENANT BASED ON PRIVATE IP ADDRESS IN VIRTUAL PRIVATE CLOUD NETWORKS AND OPERATING METHOD THEREOF

摘要

A system includes: a map-server storing EID-RLOC mapping information; an ITR receiving RLOC information on a corresponding EID from an ETR designated by the map-server based on a destination EID and a tenant identifier of a corresponding enterprise network when receiving packets for requesting allocation of computing resources from a terminal within the enterprise networks, generating an LISP data packet based on the received RLOC information and the RLOC information of the corresponding enterprise network, and transmitting the generated LISP data packet to a backbone network; and an ETR requesting the computing resources to a corresponding server within a cloud center based on the received LISP data packet to receive information on the computing resources from the server as an answer to the request when receiving the LISP data packet through the backbone network and providing the received information on the computing resources to the ITR
