Tellabs Proves IP/MPLS Data Expertise at Industry's First IP-Optical Integration Technology Demonstration NAPERVILLE, Ill., Oct. 27 /PRNewswire-FirstCall/ -- Tellabs' expertise in IP/MPLS data services was proven at the Isocore Internetworking Lab's industry-first IP-optical integration test featuring IP services delivered over an optical core. This test, which included the new Tellabs(R) 8820 multi- service switch router, the Tellabs(R) 5500 NGX-S transport switch and the Tellabs(TM) MetroWatch element manager's GMPLS software, demonstrated an IP/MPLS application delivered over a fully-dynamic, intelligent optical core that was built using a GMPLS control plane with routing. By using a single control plane to integrate an IP/MPLS application with an existing optical infrastructure, carriers will be able to simplify provisioning of network connections, increase network efficiency by allocating capacity on demand and significantly reduce the operational costs of optical networks. "Tellabs is demonstrating for service providers our expertise in IP/MPLS data services and optical networking interoperability," said Greg Nulty, senior vice president of technology planning for Tellabs. "During Isocore's industry-first IP-optical integration test, Tellabs showed how Layer 1 through Layer 3 networking, multi-vendor interoperability and dynamic network signalling protocols can help our customers save money." During the Isocore testing, the Tellabs 8820 multi-service switch router uniquely combined the functionality of an edge router, ATM multi-service switch, Frame Relay switch and Ethernet edge switch into one compact platform. Designed to provide carriers with tremendous flexibility to cost-effectively address several data service applications with minimal investment, the Tellabs 8820 multi-service switch router seamlessly interoperated and enabled three MPLS-based applications during the Isocore multi-vendor testing: -- Layer 2 virtual private network (VPN) application using the Internet Engineering Task Force's (IETF) Martini draft, which defines point-to- point MPLS connections that support virtual local networks or frame relay/ATM; -- Layer 3 VPN application using the IETF's RFC-2547bis specification, which enables IP/MPLS-based IP VPNs to help carriers offer new, high- quality IP services over their network; and -- Virtual Private LAN services (VPLS) application using the IETF's VPLS- over-MPLS draft, which enables carriers to offer point-to-point or point-to-multi-point WAN extensions of customers' LAN-based Ethernet networks at costs lower than other WAN-based alternatives. The Tellabs 5500 NGX-S transport switch, a multi-bandwidth management system that helps carriers reduce their capital expenses by integrating wideband, broadband and Ethernet-over-SONET into a single compact, scalable platform, supported the Isocore test. The Tellabs 5500 NGX-S transport switch provided interoperability with four other vendors' equipment and established information flows through the core SONET infrastructure. The Tellabs MetroWatch element manager's GMPLS software enabled the first- ever interworking between the IETF's GMPLS and ITU's OIF-UNI specifications for signalling between the IP routing network and optical transport network. "There were several significant achievements in this testing, including running IP/MPLS applications over a dynamically configured optical transport network, evaluation of the two basic architectural models for the IP optical control integration, namely the peer and the overlay models and their interworking," said Dr. Bijan Jabbari of Isocore. "Tellabs was a key participant in this testing and helped facilitate the interworking between these two architectures." The Tellabs equipment that was part of this integration test will be showcased in a live interoperability demonstration at the Isocore headquarters in McLean, Va., on Oct. 29, 2003, following the MPLS 2003 International Conference. During the conference, Andrew G. Malis, research fellow for the Tellabs Advanced Data Products group, will present "MPLS Beyond Service Provider Cores" on Oct. 28, 2003, at 4:45 p.m. In addition, Tellabs representatives will be available at the MPLS 2003 International Conference in booth 104. The goal of Isocore's Internetworking Lab is to advance internetworking through technology validation and product verification and to promote development and rapid deployment of innovative networking technologies.
