Abstract [en]

VISIR “Virtual Instrument Systems in Reality” is a remote laboratory that empowers students and researchers to design, implement, and measure on electronic circuits remotely. Users are able to connect to this system regardless of their location and use traditional lab resources online via JavaScript and HTML5 enabled web browser. The VISIR project is deployed to seven universities around the globe including Blekinge Institute of Technology (BTH) in Sweden.

In this thesis work, the main aim is to introduce load-balancing Scenarios in VISIR network in order to enable and improve load balancing, stability, and scalability in this system. The participant universities will be connected in a grid topology, and they exchange capabilities, features, and data repository in order to share workload and resources. For this purpose, the behavior of VISIR network nodes were studied and simplified as simple servers.

According to the VISIR characteristics, infrastructure, and requirement a set of design paradigms and guidelines were defined for selecting suitable load balancing mechanism to be used in VISIR system. Four different load-balancing methods described, were selected for comparison in an experimental setup. Moreover, an experimental test bed with utilizing virtual Linux machines was modeled, and chosen scenarios were implemented and tested under different circumstances i.e. various number of servers and clients.
