(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." 39 PIL Network NW Global NTT H14 CRL PIL NTT NW 7 2 ISOCORE NTT PIL PIL 40
