A network management tool for resource‐partition based layer 1 virtual private networks

Abstract

SUMMARYA 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 allocate virtually dedicated resources to customers, and to enable customers to directly manage their resources. 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

“…In addition HSVO makes use of user-definable lightpaths to connect nodes on its network by taking remote control of the network hardware involved. This involves the ARGIA and CHRONOS toolsets that can take remote control of chains of switches across a layer 1 network [7]. While some resources such as the visualization tools and the camera array require significant bandwidth, others such as OpenLabyrinth and SimMan require very little.…”
