Semester Offering: January

To provide students with practical knowledge and research background in optical networks. The emphasis will be on problems at the network layer that are unique to optical networks.


Motivation for optical networking. Wavelength division multiplexing (WDM) networks. Routing and wavelength assignment for wavelength-routed networks. Distributed lightpath setup and release. Recovery from link and node failure. Traffic grooming for access networks. Multiple access control (MAC) for local networks. Optical burst switching (OBS) and optical packet switching (OPS).


Consent of instructor.

The final grade will be computed from the following components:
assignments (30 %),
mid-semester exam (30%),
and final exam (40%).
Closed-book examination is used in both mid-semester and final exams.
