A Layer 1 Virtual Private Network (L1-VPN) has two models for service management: the resource-partition based model and the domain-service based model. In this paper, we present a network management tool for resourcepartition based L1-VPNs. A Transaction Language One (TL1) proxy is designed to achieve resource partitioning at the network element level. Building on top of a TL1 proxy, we implemented a User-Controlled LightPath (UCLP) system to support physical network brokers to assign and

With such a capability, customers are able to create wide area networks based on their traffi c pattern, and to adjust their traffi c pattern based on available resources. Copyright customers are able to use network resources in a similar way to using computing, storage and data acquisition devices. The goal is to enable customers to adapt their traffi c pattern based on resource availability, so that they may take advantage of the integrated resource allocation and traffi c adaptation. Our future work will include the security features of the system, and applying a Web Services architecture to the system. The prototype of the tool has been demonstrated at several international events. 152 delivery across heterogeneous worldwide network infrastructures including UCLP systems. Mr Savoie holds a BSc and MSc in electrical engineering from the University of New Brunswick. Scott Campbell is a network researcher in the Broadband Applications and Optical Networks group at the Communications Research Centre Canada. He has been working there since 2001, when he graduated from Dalhousie University in Halifax, Nova Scotia, Canada, with a Bachelor of Computer Science degree. At CRC he is involved in the design and development of agent-based network management and control software for all optical networks. He is currently working on the development of the User Controlled LightPaths (UCLP) project, which is now in a commercial phase called ARGIA. ARGIA is a resource management and provisioning tool based on service-oriented architectures that allows network administrators and end users to control and manage their own high-speed optical networks. Hanxi Zhang is a research engineer at the Communications Research Centre Canada. His research interests include network and system management, service-oriented software, and distributed applications. He is a key member of the CRC-i2CAT-UofO-Inocybe joint UCLP development team, responsible for the UCLP system middleware. He obtained his MSc degree from the University of Ottawa, Canada.
