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.

The main objective of this thesis work is to develop communication link between Runrev Revolution (IDE) and JADE (Multi-Agent System) through Socket programming using TCP/IP layer. These two independent platforms are connected using socket programming technique. Socket programming is considered to be newly emerging technology among these two platforms, the work done in this thesis work is considered to be a prototype.A Graphical simulation model is developed by salixphere (Company in Hedemora) to simulate logistic problems using Runrev Revolution (IDE). The simulation software/program is called “BIOSIM”. The logistic problems are complex, and conventional optimization techniques are unlikely very successful. “BIOSIM” can demonstrate the graphical representation of logistic problems depending upon the problem domains. As this simulation model is developed in revolution programming language (Transcript) which is dynamically typed and English-like language, it is quite slow compared to other high level programming languages. The object of this thesis work is to add intelligent behaviour in graphical objects and develop communication link between Runrev revolution (IDE) and JADE (Multi-Agent System) using TCP/IP layers.The test shows the intelligent behaviour in the graphical objects and successful communication between Runrev Revolution (IDE) and JADE (Multi-Agent System).

Optical Transport Network is a set of Optical Network Elements (NE) connected by optical fiber links able to provide support for optical networking using Wavelength-Division Multiplexing (WDM). In order to be able to introduce link-level applications that require NE-to-NE communication in a packet-optical network, an embedded communication channel is needed. Examples of such applications are dual-ended protection, remote configurationand path trace. By implementing a NE-to-NE communication channel, the exchange of commands and information will allow for implementation of applications that will increase the data link stability in the network. The purpose of this work has been to prove the feasibility of such a channel. This thesis discusses the possibilities of implementing such a channel adjusted to Transmode's layer 1 products without causing disturbance inthe regular traffic or affecting any existing embedded communication. It also proves the channels function in a proof-of-concept manner by demonstrating a simple Path trace application run upon an implementation of the channel on hardware. The chosen solution is an Embedded Communication Channel driver intended to provide termination points for an Embedded Communication Channel (ECC), supervising the connectivity of the channel and relay messages to applications. This thesis project has been carried out at Infinera Corporation (earlier Transmode Systems AB) during summer/autumn 2015.
