Abstract :
Summary form only given. Analyzing the different implementations for an optical layer in the context of different traffic loads, we observe limited transparency domains: Deg 3+ OEO, offers the most "cost" effective solution for 1+1 protection scheme. Network capacity was reduced by 45% even with a large traffic load of 8 Tb/s (1+1). With optical cross-connects (OXCs) at degree 3 or higher nodes, shared mesh can offer additional savings. The primary impact in capacity savings was due to improved bandwidth utilization of the transport layer indicating that core grooming is a critical component of cost effective and flexible optical network design.
