MPLS Deployment in Korea

MPLS Improves Network Infrastructure for Bases in Korea

CHALLENGE: The Project Lead, Defense Wide Transmission Systems (PL-DWTS) under the Program Manager, Defense Communications and Army Transmission Systems (PM-DCATS) has determined that Asynchronous Transfer Mode (ATM) must be removed from all Army networks. Also, as part of the Time Division Multiplexer (TDM) removal in Department of Defense (DoD) networks, Synchronous Optical Network (SONET) equipment is being replaced. The primary focus of the Army’s Network Modernization (NETMOD) Program in Korea is to design, deploy, and implement the Multi-Protocol Label Switching (MPLS) Network Architecture and Optical Transport System (OTS) in support of the ATM/SONET Elimination Project.

The scope of the project is to provide Enterprise Network Architecture, Engineering and Design Support; outside Plant (OSP) fiber testing; installation, test and acceptance of MPLS Routers, Optical Switches, Encryption Devices, and Network Management System integration. The scope also includes inter-node communication established between installed equipment at all layers; testing and node acceptance; migration of candidate phase 1 circuits; and transition of customer access connections from legacy ATM / SONET / DWDM nodes to OTS/MPLS network.

SOLUTION: In partnership with DISA, Network Enterprise Technology Command (NETCOM), 7th Signal Command, and Installation Information Infrastructure Modernization Program (I3MP); NES provides engineering, system design, installation, and integration of networks in support of NETMOD in Korea. This LandWarNet (LWN) 2025 initiative interconnects installations through the MPLS backbone, secures them via the Joint Regional Security Stack (JRSS), and enables global collaboration with Joint Service, Interagency, and Intergovernmental communication systems. The replacement IP/MPLS network is based on the Joint Information Environment (JIE) compliant architecture which provides backbone transport for enterprise services from centralized data centers.

NES completed site surveys in order to develop technical requirements, developed design documents, and detailed implementation plans. NES upgraded the transport architecture to meet C4 operational requirements, JIE CONOPS requirements, and the DISN-EN standards.

RESULT: The new IP/MPLS transport infrastructure solution consolidates disparate transport networks from different transport technologies into a single converged network architecture intended for voice, video, and data delivery that is resilient and reliable. The IP/MPLS transport infrastructure solution also provides a serial to packet interface device for non-IP traffic, that facilitates the ability to build next-generation, intelligent networks that deliver a wide variety of advanced, value-added services over a single IP/MPLS transport infrastructure.
