Modern optical networks still in development to AON (All-Optical Networks). The main goal of all related works is providing the state-of-the-art optical switching techniques, designing of new solutions and applications.  The first stage in this development was circuit-switched optical networks. In those types of networks the incoming request would dropped in case of channel blocking.  Another case – packed-switched optical networks. In those networks, the data flows divided onto many independent packets. Nowadays, this technique is the most famous.
