Experimental assessment of a cognitive mechanism to reduce the impact of outdated TEDs in optical networks
We have recently proposed and demonstrated,by means of simulation,the benefits of a simple yet effective cognitive technique to enhance stateless Path Computation Element(PCE)algorithms with the aim of reducing the connection blocking probability when relying on a potentially non up-to-date Traffic Engineering Database(TED).In this paper,we validate and analyse its performance in an emulation environment(rather than in a simulation environment)that supports impairment-aware lightpath establishment.Emulation results demonstrate the reduction in blocking probability offered by the proposed technique,which also provides negligible impact on lightpath setup time.
