Abstract:
One of the main problems in optical networks concerns routing and wavelength assignment for establishing optical circuits. Burst switching is a viable alternative to overcome the problem of idle circuit waste, but it also prevents data to pass to the electrical domain where conversion is necessary, thus making this switching purely optical. A solution to the problem of dynamic RWA in Optical Burst Switching (OBS) networks, called AntOBS, is inspired by ant colony behavior. It is used to decrease the blocking probability during the routes establishment phase. The dynamicity and self-organization are the main features of AntOBS, which through various experiments shows a reduction of the blocking probability of requests from the cross connect electro-optical network.
