    4545TIED is based on the [http://fedd.isi.deterlab.net TIED/DETER federation system], which allows a researcher to construct experiments that span testbeds by dynamically acquiring resources from other testbeds and configuring them into a single experiment. As closely as possible that experiment will mimic a single DETER/Emulab experiment.

    47 This model fundamentally supports creation of cohesive experiments (slices) from independently administered resources (components/aggregates).  Because resources are independently administered and serves different communities, the authorization system needs to support a rich delegation structure, formal semantics, efficient negotiation, and clear auditing.  The [http://www.isso.sparta.com/research_projects/security_infrastructure/abac_overview.html ABAC] system meets those requirements; TIED is integrating this into the federation system.

    4949To make use of widely distributed components it is helpful to establish guaranteed network connections between them.  TIED is addressing this by federating with testbeds that represent dynamically allocatable wide-area network resources.  The prototyping plan is to use DRAGON interfaces to configure these resources.
