Multiprotocol Label Switching (MPLS) is one of the essential technologies for enhancing IP networks of service providers (SPs). In this paper, two services that connect MPLS networks with a SP network are proposed. One is a service that connects user's MPLS networks with a SP network. The other is a service that connects SP's MPLS-VPN networks with a SP network. In order to enable these services, the virtual label switching router (VLSR) model for the Global Networking Service Platform (GNSP) is proposed. The functions that are required for the GNSP to enable the VLSR is also presented.
