Service Provisioning and Performance in 1+1/1:1 Survivable Optical Networks with Limited Add/Drop Ports and Transmitter Tunability

摘要

We develop a lightpath service provisioning algorithm for wavelength-continuous optical transport networks under 1+1/1:1 service protection. We evaluate the impacts of add/drop port availability and transmitter tunability on service provisioning performance. It is found that a limited number of add/drop ports and a limited transmitter tunability are sufficient to ensure a network to fully utilize its wavelength capacity.
