Collaborative and distributed workspaces provide opportunities for organizations to make more efficient use of expensive and specialised laboratory equipment. Along with such opportunities lies a clear need to ensure secure access to, and operation of applications and services. In this paper, we provide an introduction to the CNL Virtual Laboratory,(More)
This paper investigates and demonstrates the role of identity management as an integral part of the overall trust establishment mechanisms required for user-controlled end-to-end light-path provisioning. Within the scope of identity management, also lack of effective trust establishment procedures between the user's identity provider and the optical network(More)
To allow user applications to securely make use of various lightpath resources distributed across multiple domains in a user-friendly and privacy-preserving way requires identity management functionality. Identity and attribute information has to be provided by the user to allow for authorized access to these resources. An identity management framework can(More)
