SDN-BASED NETWORK SYSTEM FOR SUPPORTING MULTI-TENANTS AND METHOD FOR SUPPORTING MULTI-TENANTS

摘要

The present invention relates to a method for an SDN-based network system supporting multi-tenants providing an IP address, and a system for same, the method and system allowing flexible network operation using a plurality of virtual routers, support of multi-tenancy through the plurality of routers, and support of multi-tenants. The method comprises the steps of: a legacy container receiving, through a controller and an app, an ingress packet ingressed through one of a plurality of switches; generating an IP address from a virtual dynamic host configuration protocol (DHCP) server generated in the legacy container, when the ingress packet is a DHCP; and transmitting the generated IP address to a switch to which the ingress packet has been transmitted through the app and the controller.
