This condition means that theconnection will use only one path p and only one wavelength pair from the last link l of this path∑ ∑ pl.p∈Pccp .

The rest of the constraint sets denote flowconservation; the second set implies also wavelength continuity whenever required, since lightpaths areconserved using the same wavelength (or group of wavelengths).Following the same methodology we can support requests of m > 2.Project:PHOSPHORUSDeliverable Number: D.5.3Date of Issue: 31/06/07EC Contract No.: 034115Document Code: Phosphorus-WP5-D5.3100
