ABSTRACT:
A method for diverting communication traffic in an optical network from a first optical link extending between a first and a second locations, to a second optical link extending either directly between the first and the second locations or via a third location, which method comprises the steps of switching traffic at said first location from said first optical link to said second optical link. After determining at the second location that traffic has not been received along the first optical link for a pre-determined period of time, traffic is diverted at the second location to the second optical link.
