Artykuł przybliża koncepcję elastycznej sieci optycznej i charakterystyczne zagadnienia związane z jej implementacją. Przedstawiono w nim standardy styków optycznych sieci Ethernet 40 Gbit/s i 100 Gbit/s zawarte w dokumencie IEEE 802.3ba. Następnie opisano szczelinowy charakter widma elastycznej sieci optycznej, porównując ze sztywnym podziałem częstotliwości DWDM. Nakreślono problem planowania i dynamicznej alokacji zasobów w sieci.

The paper studies a novel concept of elastic optical network and selected network–level requirements of next generation optical networks. It investigates new optical IEEE 802.3ba Physical Layer Specification. Next it is compared the fixed-grid wavelength division multiplexing optical networks with flexible-grid elastic optical networks. It is important to define routing and spectrum assignment RSA algorithms, which are required for network planning and dynamic resource allocation. Mobile lab, radiocommunication services testing, radiocommunication networks measurements.
