A testbed for service testing: A cloud computing based approach

Abstract

Although simulation is an important tool in studying new emerged networks, tests on a real system are still the most ultimate way to validate the capability of a newly emerged network. Traditional tests have their drawback, because of the coupling of test service and test devices. The arise of new network architecture, industry 4.0 and the internet of things, also brings new challenges. Therefore, a testbed for service testing and data process based on cloud computing is proposed. In this testbed, a test is realized as a service hosted by one or several cloud hosts, i.e., test as a service (TaaS). The relationship of different kinds of services in a testbed is modeled, based on the Lotka-Volterra model. The testbed implementation is demonstrated, based on cloud computing, using a typical video test as an example. It is proved that our testbed for service testing and data process is practicable and effective.
