Exact performance analytical model for spectrum allocation in flexible grid optical networks
We propose an exact model depicting the performance of spectrum allocation in FGON. We consider multi-class calls with both first-fit and random-fit policy. The interplay between classes of calls does affect the blocking performance. The fragmentation rate reaches its maximum value when the load is moderate. Performance is affected by the ratios of both loads and average residency times.
