Existing cloud gaming systems, however, are closed-source with proprietary protocols, which raises the bars to setting up testbeds for experiencing cloud games. In this paper, we present a com- plete cloud gaming system, called GamingAnywhere, which is to the best of our knowledge the first open cloud gam- ing system. In addition to its openness, we design Gaming- Anywhere for high extensibility, portability, and reconfigura- bility. We implement GamingAnywhere onWindows, Linux, and OS X, while its client can be readily ported to other OS’s, including iOS and Android. We conduct extensive ex- periments to evaluate the performance of GamingAnywhere, and compare it against two well-known cloud gaming sys- tems: OnLive and StreamMyGame. Our experimental re- sults indicate that GamingAnywhere is efficient and pro- vides high responsiveness and video quality. For example, GamingAnywhere yields a per-frame processing delay of 34 ms, which is 3+ and 10+ times shorter than OnLive and StreamMyGame, respectively. Our experiments also reveal that all these performance gains are achieved without the expense of higher network loads; in fact, GamingAnywhere incurs less network traffic. The proposed GamingAnywhere can be employed by the researchers, game developers, ser- vice providers, and end users for setting up cloud gaming testbeds, which, we believe, will stimulate more research in- novations on cloud gaming systems.
