Impact of optical hop constraints on the IP/MPLS-over-WSON Networks CAPEX
In this work, the impact of hop constraints on the CAPEX of multi-layer IP/MPLS over WSON networks is evaluated under different scenarios. By routing lightpaths with different number of transparent hops, the cost of networks varies significantly. This effect is thoroughly analyzed with a heuristic a...

By routing lightpaths with different number of transparent hops, the cost of networks varies significantly.

The main conclusion extracted is that limiting the transparent reach in such multi-layer networks can give a good tradeoff between CAPEX of IP/MPLS networks and WSON networks, and even lead to significant savings in CAPEX when compared to longer lightpaths routing strategies. |
