TaaSOR – Testbed-as-a-Service Ontology Repository

Semantic Web technologies for pay-as-you-go networking services integration

“…We have developed a proof of concept web based application to demonstrate what and how Semantic Web technologies can offer to the testbed owners and their users [7]. The idea is that we show how testbed services can described by means of the semantic knowledge about networking and experimentation.…”

“…If services from different testbeds are described that way then they can be used by any person that is interested in that domain with no need for knowing about details of concrete implementation, residence and execution of those services. We call this proof-of-concept application TaaSOR, which stands for Testbed-as-a-Service with Ontology Repository [7]. It enables us to collect descriptions of services that exists in testbeds, then using networking domain knowledge we describe what services can do, and after that we can create experiments without knowing where services that will be invoked physically are deployed.…”

A Framework for Dynamic Composition of Communication Services

“…2, Article 32, Publication date: December 2014. associated domain ontology. In recent efforts to federate experimental infrastructures, such as those in GENI [GENI.net Global Environment for Network Innovations 2013] and FIRE [Future Internet Research and Experimentation 2013], the importance of a common information model to provide unified configuration and control has been recognized [Ren and Jiang 2011;Tosic et al 2012]. To achieve such goal, a common and infrastructure-independent way of expressing experimental settings such as channel width, sweeping step, and time duration of the experiment should be defined.…”

“…This is best done using a high-level representation language, often by XML syntax, that is machine interpretable, standardized, and designed to support interoperability. Efforts in creating domain ontologies and then mapping these to upper level, common ontologies are in progress for specific types of experimental infrastructures [Tosic et al 2012].…”

“…Because the declarative language uses an ontology as its vocabulary, it is possible to align or merge it with ontologies used by other testbeds [Tosic et al 2012] to achieve federation. In a federated environment that enables remote experimentation, a user located anywhere in the world and having an Internet connection is able to design and configure an experiment and run it on several testbeds with minimal effort.…”
