Apparatus and method for providing multiprotocol label switching (MPLS) based virtual private network (VPN)

摘要

A virtual private network (VPN) based on a multi protocol label switching (MPLS) technique is established by an MPLS-based VPN providing apparatus and method. The MPLS-based VPN providing apparatus and method are capable of simplifying the use of protocols, reducing a load, and guaranteeing quality of service (QoS) by adopting a centralized control structure.
