The elastic optical network (EON) can accommodate dynamic and diverse demands of next-
generation applications by provisioning flexible lightpaths for them. Consequently, blocking …

A lightpath configuration algorithm considering a multi-period traffic model is presented and
evaluated to a realistic German core network study. Strategically exploiting BVT excess …

In this paper, we study the effect of load-aware margin selection on the performance of
elastic optical networks (EONs) in dynamic service provisioning. First, a mixed-integer linear …

Flexible optical network is promising to accommodate high-capacity demands in next-
generation networks. To ensure uninterrupted communication, existing lightpath …

We focus on quality of transmission (QoT) guaranteed routing, modulation, and spectrum
allocation (RMSA) in shared backup path protection (SBPP) based elastic optical networks …

Nonlinear impairments especially Four-Wave Mixing (FWM) affect the overall optical signal-
to-noise ratio (OSNR) by introducing additional crosstalks into the system. FWM is a fiber …

With the emergence of various applications with diverse transmission requirements, optical
networks must support multiclass service provisioning and prioritization. This paper studies …

In this paper, a novel energy-aware grooming-based algorithm, named energy minimization
algorithm (EMA), is proposed that aims at providing the quality of service requirements in …

The capacity expansion of a single time division multiplexing (TDM) or wavelength division
multiplexing (WDM) domain is difficult to cope with long-term capacity pressure. The …

Elastic optical networks allow for a division of the optical spectrum into frequency slots,
which can be combined to create channels with bandwidth defined by demand. Their …
