There is an enormous insistence for designing optical transport networks in sucha fashion, so that it has enhanced utilization, reduced spare link capacity, minuscule path length and an escalated level of survivability. Inter-cycle switching (ICS), one of the more recent approaches that is based on idle p-cycles and used to shorten the length of restoration paths in flawed models, is the most promising technique for the survivability of optical transport networks.However, ICS model fails to protect node and span at a time. Using idlep-cycles reduces the inherent span and node failure restorability of failure in thep-cycle design model, whereas ICS releases the most conventional restoration path by only using a small portion of the idle p-cycle, but it had several glitches, which were enhanced by several proposed methods, of which one significantone is Inter-cycle Switching. In the proposed work the authors analyzed the performance of the Inter-cycle Switching and eliminated the snags hindering its performance. Overhear the authors have analyzed Hybrid Inter-cycle Switching (HICS) in various scenarios of span and node failure and have proposed a method for ensuring an effective and efficient restoration process in the event ofspan and node failure as well.
