Development of algorithms for scheduling WDM network migrations
The rapid technological evolution of telecommunication networks demands service providers to regularly update their technology, with the aim of remaining competitive in the marketplace. However, upgrading the technology in a network is not a trivial task. New hardware components need to be installed in the network and during the installation, network connectivity may be temporary compromised. In the proposed PhD project, we will investigate the problem of finding a schedule of the fiber link upgrades that corresponds to the best compromise among the total service disruption time, the cost, the risk analysis, the set of alternate paths, and the minimization of labor time.
