Partial defragmentation in elastic optical networks
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014In elastic optical networks, the lightpaths setup and tear down processes may cause the so-called spectrum fragmentation issue, degrading spectrum utilization, increasing lightpath rejection ratio, and this is especially critical under dynamic traffic scenarios.

Soft Failure Localization in Elastic Optical Networks
2018 20th International Conference on Transparent Optical Networks (ICTON), 2018Soft failure localization to early detect service level agreement violations is of paramount importance in elastic optical networks (EONs), while it allows anticipating possible hard failure events. Nowadays, effective and automated solutions for soft failure localization during lightpaths' commissioning testing and operation are still missing. In this

Transparent virtual network embedding in elastic optical networks
2016 IEEE 37th Sarnoff Symposium, 2016Network visualization in Elastic Optical Networks (EONs) utilizes the flexible spectral resources to map Virtual Networks (VN) requests onto the physical substrate network. The process of mapping the VN requests onto the physical substrate network is called Virtual Network Embedding (VNE) problem.

Scalable elastic optical path networking models
2016 18th International Conference on Transparent Optical Networks (ICTON), 2016In order to face the steady growth of the optical networks, network operators are now moving to elastic optical networking, with the challenge of optimizing the spectrum usage through the so-called routing and spectrum assignment (RSA) problem. It is a much more difficult problem than the classical routing and wavelength assignment (RWA) problem, for ...

Hardware-supported softwarized and elastic optical networks
2018 International Conference on Optical Network Design and Modeling (ONDM), 2018We present elasticity and agility in softwarized optical network construction, service continuation, and service update. Programmability among multiple network protocols and multiple classes of transmission and processing speeds is a necessary solution for lower CAPEX and agile network setup.
