Abstract In WDM networks using a fixed frequency grid, transmission rates can vary for different connections, leading to inefficient bandwidth utilization in optical fibers with lower-rate connections using wide frequency slots. In elastic optical networks (EONs), the frequency grid is made flexible, thereby improving the effective ...

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.
