Metamorphic network systems based on autonomous WDM devices

Abstract

We propose a metamorphic network system, based on autonomously controlled wavelength division multiplexed devices. We will address the issue of how to assure and manage wavelength accuracy and controllability over the whole network to implement practical optical path routed networks. Our solution uses smart devices with wavelength calibration tables to construct systems that can be self-controlled according to their own stored physical layer information. The devices are interactive and share renewable information and are therefore useful for realizing selfreconfigurable (metamorphic) network systems. To verify the proposed architecture, we performed practical examinations using subsystems with wavelength-managed 'disk filters' in a field trial (Chitose trial).
