In recent years, OFDM has been the focus of extensive research efforts in optical
transmission and networking, initially as a means to overcome physical impairments in …

The routing and spectrum assignment problem has emerged as the key design and control
problem in elastic optical networks. In this work, we show that the spectrum assignment (SA) …

Recently, flexible grid and elastic-rate transponders have emerged as evolutionary
technologies to satisfy the ever-increasing demand for higher spectrum efficiency and …

This paper proposes an MILP (Mixed Integer Linear Programming) formulation for the
design of flexgrid optical networks under multiple modulation formats and noise constraints …

Historically, network technology has largely been “one size fits all”; for example, a transmitter
card generates a single data rate with a specified optical reach. The flexible approaches …

The routing and spectrum assignment (RSA) problem has emerged as the key design and
control problem in elastic optical networks. In this work, we provide new insight into the …

Optical spectrum is becoming scarce with traffic demand growing at 40% per year. Today,
the optical spectrum of a fiber is divided using wavelength-division multiplexing (WDM) into …

Mixed line rate (MLR) and flexible-grid optical networks are two promising network
paradigms for next generation optical networks. In MLR optical networks, different optical …
