Abstract
Two impairment-aware path computation element (PCE) architectures, exploiting candidate paths, are presented. Novel PCE protocol extension is proposed to improve path computation in multi bit-rate optical networks affected by detrimental non-linear effects among 10 Gb/s and 100 Gb/s lightpaths. The PCE architectures have been successfully experimented on a real 10-100 Gb/s testbed.
