Data Gathering in Optical Networks with the TL1 Toolkit

Abstract. This paper describes a new tool for gathering (performance) data from optical network devices. During the last few years many National Research and Education Networks (NRENs) have deployed hybrid networks. These hybrid networks consist of a traditional routed IP part and an innovative optical part. On the optical part lightpath services are offered. These lightpaths are high speed (up to 10 Gbps) circuits with a deterministic quality of service. Not all optical devices used in these networks have full SNMP support, so the traditional management and monitoring tools cannot be used. Therefore we designed and implemented the TL1 Toolkit which supports management, data gathering and monitoring of optical devices
