Impact of switching technologies on resilience mechanisms in transparent and translucent networks

Transparent optical cross connects based on Wavelength Selective Switches using the broadcast-and-select principle are very cost efficient for switching trunk traffic. In this paper, we study the impact of the directionality of this architecture on restoration. c 2008 Optical Society of America OCIS codes: (060.4261) Networks, protection and restoration ; (060.4510) Optical communications; (060.6718) Switching, circuit
