The optical path (OP) technology, which employs both wavelength-division multiplexing and wavelength routing, will be the key to enhanced network integrity and an ubiquitous broadband integrated services digital network (B-ISDN) in the future. To construct the OP network, path accommodation design that can solve simultaneously the problems of path routing(More)
At iGrid2005, we conducted a live demonstration where our Grid scheduling system co-allocated computing and network resources with advance reservation through Web services interfaces using the Grid Resource Scheduler (GRS), the Network Resource Management System (NRM), which is capable of GMPLS network resource management, and a GMPLS-based network(More)
The Lambda-on-demand functionality with link aggregation to accommodate the dynamic bandwidth demands of an ultra-high-resolution visualization application was realized in over a US nationwide photonic network for the first time. 1. Introduction A photonic network comprised of Photonic Cross Connects (PXC) with Generalized Multi-Protocol Label Switching(More)
SUMMARY This paper discusses global area optical transport ring networks using wavelength division multiplexing (WDM) technologies and proposes a novel optical add/drop multiplexer (OADM) architecture suitable for such an application field. Study on the requirements of a global area ring application elucidates the appropriate ring/ protection architecture(More)
