“…Whether a specific routing problem is tractable or not depends on the number and type of criteria (or objective functions) and constraints. Routing problems are defined for discrete or continuous criteria: discrete for, e.g., optical networks [9] and networks capable of advance resource reservation [18], continuous for, e.g., networks with quality-of-service requirements [19,20]. In Reference [21], ten bicriteria shortest path problems were studied, some of them were proven NP-complete, others were solved in polynomial time with a novel multilabeling algorithm.…”

“…Dynamic routing without DPP is simpler, but its status seemed unclear. In References [ 9 , 10 ], the problem was solved with exponential worst-case time and memory complexities. However, the dynamic routing problems in EONs can be solved exactly in polynomial time with the spectrum scan method [ 11 ], introduced in Reference [ 12 ].…”

“…Η έρευνα για τη δυναμική βελτιστοποίηση του δικτύου είναι αρκετά εκτεταμένη. Στις [59] και [60] παρουσιάζονται συγκεκριμένοι προσαρμοστικοί αλγόριθμοι δρομολόγησης και ανάθεσης μήκους κύματος -routing and wavelength assignment (RWA). Κάνουν διαστρωματική βελτιστοποίηση με την έννοια ότι λαμβάνουν υπόψιν τις μετρικές ποιότητας σήματος του φυσικού επιπέδου ώστε να βελτιώσουν το QoT των μονοπατιών και να μειώσουν το ρυθμό απόρριψης νέων συνδέσεων.…”
