TIED
v22 v23 45 45 TIED 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. 46 46 47 This model fundamentally supports creation of cohesive experiments (slices) from independently administered resources (components/aggregates). Because resources are independently administered and serve sdifferent 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.47 This model fundamentally supports creation of cohesive experiments (slices) from independently administered resources (components/aggregates).

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.
