DICONET promises a disruptive solution for the development of the core network of the future
It is the vision and goal of the consortium to provide ultra high speed end-to-end connectivity with quality of service and high reliability through the use of optimized protocols and routing algorithms that will complement a flexible control and management plane offering flexibility for the future network infrastructure.

In order to realize the core networks of the future utilizing the translucent or transparent optical networks the DICONET1 vision is presented in this article. Providing ultra high-speed end-to-end connectivity with quality of service and high reliability through the exploitation of optimized protocols and lightpath routing algorithms that will complement a flexible control and management plane is integrated in the proposed solution. Physical layer impairments and optical performance are monitored and incorporated in impairment aware lightpath routing algorithms. These algorithms will be integrated into a novel dynamic network planning tool that would consider dynamic traffic characteristics, a reconfigurable optical layer, varying physical impairment and component characteristics. The network planning tool along with extended control planes will make possible to realize the vision of optical transparency possible.

Optical networks are moving from opaque and translucent architectures towards alloptical (transparent) architectures. In translucent architectures a small amount of regeneration (e.g. optical-electronic-optical conversion) is available in the network.
The incorporation of the physical impairments in the routing and wavelength assignment (RWA) problem in transparent optical networks has recently received some attention from the research communities. This work compiles a comprehensive survey of the proposed algorithms that address this issue. The physical layer impairments and related classification in optical networks are initially presented followed by physical layer impairments
(PLI) constrained and aware RWA algorithms. Algorithmic approach, current PLI-RWA proposals, impact of wavelength conversion on these algorithms, protection and resilience considerations, and proposed extensions to control planes are covered in this work. Further research topics are presented in this study.
