Experimenter: Researchers at the University of Sao Pãulo(Brazil)

TEFIS Testbeds involved: ETICS and Kyatera

Short description about the experiment and the application/solution being developed /tested:
The eHealth application is a Future Internet solution under development, which is based in long distance surgery over non-dedicated networks with the help of a Distributed Patient Medical Record (PMR). The usage scenario of the solution is during a surgery in which a surgeon operates a patient, in another hospital, over a long distance with the data passing through a non-dedicated connection. In this procedure the surgeon will have access to all patient medical history and all new information, since the surgery video can be persisted in the PMR. The application also includes the functionality to test the input generated by the surgeon on the procedure, and tell if this type of network is capable to handle the long distance, with an acceptable jitter and response time.

Problems to be solved/what to be tested:
The purpose of this experiment is to measure the minimum resources necessary for the proper functioning of such an application. The goal here is to run the eHealth application under ideal conditions and with almost unlimited resources in order to measure its proper limits, and then, stress the network to see what happen when it is overloaded. After that several parameters will be adjusted, independently or not, and measure their impact on the overall performance of the application. This experiment will allow the exeprimenter to measure what is the minimum bandwidth required for its functioning and what level of latency and jitter can be accepted without losing quality in usability, as data-loss could create a disaster for the medical treatment of the patient, and a high jitter can misled the surgeon during the procedure.

Testbeds involved in the experiment and what kind of support do they provide for the experiment:
Running this experiment requires from the experimenter to use multiple TEFIS connected testbeds: ETICS in Italy and the KyaTera testbed in Brazil. By using ETICS capabilities, the eHealth solution developers are able to produce the most efficient piece of code, in term of execution capabilities (CPU and memory usage, speed of execution, etc), as well as to create the application package and easing the application deployment due the large amount of dependencies; and for the KyaTera, once the application is compiled, it will be deployed on the testbed network, which is an optical network, that can provide high network capabilities, in term of bandwidth, error rate, latency, and jitter. Thus, it can be considered as a network with infinite resources, or can be an overload network, simulating the two capacity edges.

Expected benefits from TEFIS:

• Single login or multiple testbed
• Storage of experimental data in unique virtualised location
• Support to locate, select and exploit different testbed resources
• Ability to search for and interrogate related experiment
