17 BUSINESS WIRE, October 27, 2003 (10/27/2003) MPLS 2003 International Conference and Exhibits Opens in Washington, DC BUSINESS WIRE October 27, 2003; McLean, Virginia Isocore today announced the opening of the MPLS 2003 International Conference which will provide a forum for leading MPLS vendors, test equipment manufacturers, and premier ISPs to showcase next generation MPLS products and services. ( ) Also participating at the exhibits is NTT Network Systems Laboratories demonstrating world's first Multicast MPLS protocol jointly developed with Motorola. The demo will shows various data distributing scenarios over traffic engineered multipoint LSPs. Additionally, NTT, NEC Corporation, Furukawa Electric Co., Ltd., and Mitsubishi Electric Corporation will highlight PIL's activities. 33 BUSINESS WIRE, October 29, 2003 (10/29/2003) 10/29/2003 Sycamore Demonstrates Multi-vendor IP/Optical Interoperability Featuring MPLS Services over an Intelligent Optical Core Sycamore's SN Intelligent Optical Switch successfully demonstrates standards-based GMPLS signaling and routing Chelmsford, Mass. - Sycamore Networks, Inc. (NASDAQ: SCMR), a leader in intelligent optical networking, today announced that the company successfully demonstrated Generalized Multi-Protocol Label Switching (GMPLS) multi-vendor interoperability in Isocore's IP/Optical Integration demonstration -- held in conjunction with the MPLS 2003 International Conference - - at the Isocore Internetworking Lab in McLean, Va. on Wednesday, October 29. "By unifying network operations between the IP and optical layers, GMPLS provides the means for service providers to reduce operations costs and improve network efficiencies," said Naoaki Yamanaka, Ph. D., of NTT Network Innovation Laboratories. "Validating the inter-working of IP/MPLS and GMPLS is an important step in the evolution toward more flexible next-generation optical networks." 34
