Routing and Wavelength Assignment for Primary Lightpath
For each new lightpath setup request, the LMN first solves the routing and wavelength assignment problem for the primary lightpath. The primary lightpath is selected from among the free wavelengths, and the wavelengths being used for backup. If there is a lightpath having the same source-destination pair as the new lightpath, the new lightpath is set up along the same route as the existing lightpath. This is because in IP over WDM networks, the IP layer recognizes that paths on different routes...
Mobile wireless outage index
For wireless networks we can use a modified version of the ANSI Committee T1 outage index used for wireline networks, in order to incorporate the wireless customer registration. A mobile wireless customer has to register to establish a virtual connection to the mobile wireless service provider, whereas a wireline customer is always registered via the physical connection to the wireline service provider. For this reason, the mobile outage index is given by the sum of two outage indexes, one for...
