Abstract:
The increases in communication bandwidth provided by fiber optics and high-speed switching technologies have shifted the limiting factor in data throughput from the communication link to the communication processing. The communication processing for open systems interconnection (OSI) in particular is quite heavy due to the inclusion of data transfer syntax conversion in order to assure interoperability between different machine types. In this thesis report, two multiprocessing architectures are considered as protocol processing engines for OSI communications. The conventional approach is to

Abstract:
This master thesis examines the development of the two earlier independent IR protocols Z39.50 and SR (Search and Retrieve, ISO 10162/10163), now Z39.50/SR, from the beginning of the 80s to 1996 and their functionality in the client/server environment. Z39.50 applications in library systems will allow easy access to information regardless of platform or location. The use of Z39.50 will create a new user environment. Almost all the library systems of the market support the Z39.50 and surprisingly the use of it in Sweden lied on a very low leve! in 1996. This thesis was followed-up by an intervi

Abstract:
A central issue in significantly large industrial distributed computer control systems, but one largely ignored by systems designers, is the question of the real-time handling of data. Recently, though, it has become evident that many installed systems are not able to meet the requirements of full plant-wide integration and synchronization. It is becoming clear that future distributed control systems will only be capable of performing the very exacting tasks asked of them if they are supported by an inherently time-conscious communication system, together with an ability to handle data from a

Abstract:
This thesis addresses the problem of conformance testing of communication protocol implementations. Test sequence generation techniques for finite state machines (FSM) have been developed to solve the problem of high costs of an exhaustive test. These techniques also guarantee a complete coverage of an implementation in terms of state transitions and output functions, and therefore provide a sound test of the implementation under test. In this thesis, we have modified and applied three test sequence generation techniques on the class 0 transport protocol. A local tester and executable test

Abstract:
Network coding is a technique used to increase the capacity of a network by combining messages sent over the network. The combined messages could be separated by using sufficient original messages which were used to combine the messages. Network coding can be implemented in different layers of the 051 stack, but to date a complete comparison between different implementations of network coding has not been done.

Abstract:
Denial of service attacks (DoS) are a common threat to many online services. These attacks aim to overcome the availability of an online service with massive traffic from multiple sources. By spoofing legitimate users, an attacker floods a target system with a high quantity of packets or connections to crash its network resources, bandwidth, equipment, or servers. Packet filtering methods are the most known way to prevent these attacks via identifying and blocking the spoofed attack from reaching its target.

Abstract:
This thesis discusses the problems of the conventional ISO 9646 methodology for OSI conformance testing, and proposes a new methodology based on trace analysis. In the proposed methodology, a trace analyzer is used to determine whether the observed behavior of the implementation under test is valid or invalid. This simplifies test cases dramatically, since they now need only specify the expected behavior of the IUT; unexpected behavior is checked by the trace analyzer. Test suites become correspondingly smaller. Because of this reduction in size and complexity, errors in test suites can be fou

That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..

Abstract:
Suite a l'explosion du marche de l'interconnexion des reseaux locaux (lans) et aux offres de nouveaux services multimedia (la voix, les donnees et l'image), les reseaux a large bande (haut debit) prennent de plus en plus d'importance sur le marche des reseaux de telecommunications. Gerer un tel environnement est une tache tres importante et tres complexe, a cause des architectures heterogenes, des grandes vitesses de transmission, des larges couvertures et du deploiement de nouvelles techniques de transmission et de commutation (sdh et atm). Les approches de gestion utilisees dans les reseaux

Abstract:
Nowadays we are witnessing to a continuous increasing of the number of IoT devices that must be configured and supported by modern networks. Considering an industrial environment, there is a huge number of these devices that need to coexist at the same time. Each one of them is using its own communication/transport protocol, and a huge effort needs to be done during the setup of the system. In addition, there are also different kind of architectures that can be used. That’s why the network setup is not so easy in this kind of heterogeneous environment. The answer to all these problems can be

Il lavoro è stato suddiviso in tre macro-aree. Una prima riguardante un'analisi teorica di come funzionano le intrusioni, di quali software vengono utilizzati per compierle, e di come proteggersi (usando i dispositivi che in termine generico si possono riconoscere come i firewall). Una seconda macro-area che analizza un'intrusione avvenuta dall'esterno verso dei server sensibili di una rete LAN. Questa analisi viene condotta sui file catturati dalle due interfacce di rete configurate in modalità promiscua su una sonda presente nella LAN. Le interfacce sono due per potersi interfacciar

Abstract:
L'objet de cette these est de definir une methodologie pour la specification d'architectures d'interconnexion de reseaux heterogenes, et d'integrer cette methodologie au sein d'un systeme base sur l'utilisation de techniques d'intelligence artificielle. La methodologie permet: 1) d'evaluer l'incompatibilite des reseaux a interconnecter (lorsque des adressages et/ou les couples service-protocole d'une couche sont incompatibles, les entites de cette couche sont incapables de s'identifier et/ou de dialoguer), 2) de realiser une specification orientee fiabilite de l'architecture d'interconnexion r

Cette thèse traite de la validation de la propriété d'interopérabilité entre un ensemble d'équipements dans les systèmes et applications distribués temps réel. Contrairement au peu de travaux qui ont été déjà menés sur le sujet et qui proposent une validation basée sur la technique de test sur plate-forme, nous avons proposé une méthodologie de validation basée sur une technique de vérification. Etant donné un système composé d'un ensemble d'équipements avec leurs caractéristiques de conformité et un ensemble de processus d'application distribués, la validation de la propriété d'interopérabili

Les travaux presentes dans ce memoire ont pour cadre la recherche de nouveaux services et protocoles de transport, aptes a supporter le transfert de donnees multimedia en tenant compte des exigences applicatives en termes de hauts debits et de synchronisation. L'approche proposee repose sur la definition et le developpement d'un nouveau concept: la connexion d'ordre partiel (poc - partial order connection), etablissant un lien conceptuel entre les modes de service/protocole orientes-connexion tels que tcp, et sans connexion tels que udp.

L'image est aujourd'hui un support privilegie de la communication. De plus en plus d'applications informatiques font appel aux images ou sont dediees a la manipulation d'images. Pour ces applications, les principaux besoins sont le stockage, le transfert et la visualisation. A partir de l'analyse de ces besoins, specifiquement le transfert et la visualisation, je definis les principales caracteristiques du transfert et de la visualisation des images.
