“…The restoration problem for transport networks with a limited number of wavelengths is addressed by Nagatsu et al [48]. The ratios of the number of optical crossconnect ports with and without wavelength conversion for a polygrid network are: 1) 30-40% with ; 2) 50-60% with ; and 3) 70-80% with .…”

“…Due to the joint assignment of routes and wavelengths, the design problem for WS networks is much more difficult, and the solutions given by the heuristic algorithm are further away from the optimum solution. Second, the service and restoration path problems are separately solved in [48]. Better solutions will be obtained if these two problems are combined and jointly solved which will result in more resource sharing between service and restoration layers.…”

“…Nagatsu et al [48] presented a more realistic formulation of the static network design problem that minimizes the number of fibers in the network such that the network is able to carry a given traffic demand. A heuristic algorithm is proposed for minimizing the total number of ports (both inter and intraoffice) in the network.…”

Abstract-Wavelength division multiplexed point-to-point transport is becoming commonplace in wide area networks. With the expectation that the next step is end-to-end networking of wavelengths (in the optical domain without conversion to electronics), there is a need for new design techniques, a new understanding of the performance issues, and a new performance evaluation methodology in such networks. This paper describes approaches to that end, summarizes research results, and points to open problems.

“…The routing algorithms used for the WP and the VWP scheme are those reported in [6]. These are based on an heuristic procedure of path accommodation and allows the OXC scale needed to accommodate a fixed traffic volume to be determined.…”

“…These classes of algorithms have been compared both considering the number of required WDM channels per fiber in the case in which a single fiber link exists between each couple of OXCs [5] and considering the required OXC dimension (number of i/o ports) in the case in which the maximum number of wavelengths per fiber is fixed [6,4]. The most significant comparison is the latter, since the number of wavelengths is generally constrained by the adopted technology; its main result is that the VWP and the PVWP allow a sensible save in OXC ports with respect to the WP.…”

Memory operations based on variation of a molecule's properties are important because they may lead to device miniaturization to the molecular scale or increasingly complex information processing protocols beyond the binary level. Molecular memory also introduces possibilities related to information-storage security where chemical information (or reagents) might be used as an encryption key, in this case, acidic/basic reagents. Chemical memory that possesses both volatile and non-volatile functionality requires reversible conversion between at least two chemically different stable or quasi-stable states. Here we have developed the phenol-phenoxide equilibrium of phenol fluorophores as a data storage element, which can be used to write or modulate data using chemical reagents. The properties of this system allow data to be stored and erased either in non-volatile or volatile modes. We also demonstrate non-binary switching of states made possible by preparation of a composite containing the molecular memory elements.
