All-Optical Traffic Grooming in Elastic Optical Network
Optical Fiber Communication Conference/National Fiber Optic Engineers Conference 2013, 2013Novel architecture based on all-optical traffic grooming in optical node for elastic optical network is proposed. BER measurements experimentally demonstrate efficient adaptive switching and processing of variable fragmented traffic, leading to improved network scalability and efficiency.

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.

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.

Cross-Layer Adaptive Elastic Optical Networks
Journal of Optical Communications and Networking, 2018Optical networks are designed to be operated statically: lightpaths are provisioned for uninterrupted operation for several years using high margins to anticipate the deterioration of their quality of transmission (QoT) from various factors (equipment aging, malfunctioning, and maintenance operations).

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 ...

Complex Elastic Optical Network Simulator (CEONS)
2015 17th International Conference on Transparent Optical Networks (ICTON), 2015This paper presents the features of an advanced software simulator for the Elastic Optical Network (EON) - Complex Elastic Optical Networks Simulator (CEONS). The CEONS is as a test environment for solving three main issues addressed in EON: Routing and Spectrum Assignment (RSA) problems; Routing, Modulation and Spectrum Assignment (RMSA) problems, and

On the worthiness of flexible grid in elastic optical networks
2015 European Conference on Optical Communication (ECOC), 2015Elastic networks are agreed as the right solution to improve optical networks performance. This work discusses about flexible grid usage value, supported by extensive simulations. Elastic connections using fixed grid spectrum allocation can actually lead to better network performance.
