To meet the growing need for higher capacities, a new architecture for an all-optical Internet is proposed. Based on traffic statistics and number of available wavelengths in the WDM trunks at network nodes, wavelength allocation and assignment is performed. Distribution of wavelength allocation decisions is accomplished using signaling messages encapsulated in optical “labels” or “tags” associ...

We calculated the wavelength of the atrial impulse in chronically instrumented conscious dogs by measuring both conduction velocity and refractory period: wavelength = refractory period X conduction velocity. Implantation of multiple stimulating and recording electrodes allowed wavelength determination at four different areas: the right and left parts of Bachmann's bundle and the free walls of ...

Distributed lightpath establishment in WDM optical networks involves, apart from routing, two important steps, namely wavelength selection and wavelength reservation. In uni-wavelength reservation protocols, often multiple connection requests unknowingly compete for the same wavelength, even when other free wavelengths are available, resulting in a collision. Attempting multiple wavelengths for...
