Automatic routing in DWDM transport networks: concepts and field trials

In this paper we present concepts and field trails of automatically switched DWDM networks (ASON). One test network was part of the German field trial "KomNet". The other network is developed and will be tested in the "CAPRICORN" project, a project in the framework of IST (European Community). We focus our investigations on the photonic layer and show results of our experiments on the performance of the network control plane. Each testbed consists of 4 optical cross connects (OXC) in an optically meshed network configuration for the metropolitan and regional area. The main goals are to demonstrate in the field an optical network managed by a control plane and to investigate the functionality of automatically switched transparent optical networks.
