v7 v8 20 20 Release the fedid-bound allocation. At this point a testbed may reclaim any local resources bound to that allocation outside the experiment resources. 21 21 22 These are encoded as the '''!RequestAccess''', '''!ReleaseAccess''', '''!StartSegment''', and '''!TerminateSegment''' operations in the [source:wsdl/ trunk/fedd.wsdl web service interface.]22 These are encoded as the '''!RequestAccess''', '''!ReleaseAccess''', '''!StartSegment''', and '''!TerminateSegment''' operations in the [source:wsdl/fedd.wsdl web service interface.] 23 23 24 24 In the future we will be expanding these operations to include support for more informantion and manipulation of federated experiments, inclucing manipulating nodes in an experiment and changing experiment topology. … … 28 28 The two keys to an effective interface for local resource allocation guided by the global event controller are a representation of credentials and authorization and a representation of the resources being requested. This section deals with the resource description for sub-experiments at differing levels of abstraction depending on the testbed. 29 29 30 We introduce topdl (topology description language) as the language for topology description. An [source:wsdl/t runk/topdl.xsd XSD representation] and [source:fedd/trunk/federation/topdl.py sample manipulation library] are available from the source tree. The goal of the language is to represent experimental topologies at sufficient detail so that local testbeds can allocate resource configured appropriately for the experiment.30 We introduce topdl (topology description language) as the language for topology description.
