Abstract:

This Master's thesis deals with modeling and simulation of BGP protocol within the OMNeT++ environment. The BGP protocol is described with employed data structures and the finite state machine of BGP peering. Next, the basic configuration is outlined involving the setup of the BGP protocol on Cisco devices. Further, BGP for OMNeT++ state-of-the-art is investigated together with its lack of functionality and issues. The second part of this thesis deals with design, implementation, and testing of the new functionality of BGP protocol and simulation models. The last section describes the overall

Abstract:

Border Gateway Protocol (BGP) is the backbone of routing infrastructure in the Internet. In its current form, it is an insecure protocol with potential for propagation of bogus routing information. There have been several high-profiles Internet outages linked to BGP in recent times. Several BGP security proposals have been presented in the literature; however, none has been adopted so far and, as a result, securing BGP remains an unsolved problem to this day. Among existing BGP security proposals, Secure BGP (S-BGP) is considered most comprehensive. However, it presents significant challenges

The Border Gateway Protocol (BGP) is an important routing protocol used to exchangerouting information among autonomous systems on the Internet.

In this thesis, current secure solutions are reviewedand evaluated against a list of security and deployment requirements.

Abstract:

This document specifies a simple signalling mechanism for inter-domain QoS marking using a BGP Extended Community QoS Attribute. Class based packet forwarding for delay and loss critical services is currently performed in an individual AS internal manner. The new QoS marking attribute makes the QoS class setup within the IP prefix advertising AS known to all access and transit ASes. This enables individual (re-)marking and forwarding treatment adaptation to the original QoS class setup of the respective IP prefix. The attribute provides the means to signal QoS markings on different layers,

Tout d'abord,nous étudions le déploiement des points d'échange Internet (IXP) en Amérique latine et constatons que certains pays sont en situation d'échec dans leur déploiement IXP, c'est-à-dire aucun IXP du tout, ou bien que l'IXP n'a pas réussi à attirer suffisamment de membres. Deuxièmement, nous étudions BGP, le protocole de routage utilisé sur Internet, et en particulier s'il existe des mensonges BGP, c’est à dire si les routes par lesquelles les paquets circulent réellement sur Internet divergent des chemins q

Abstract:

Cloud computing platforms allow users to deploy geographically distributed applications on servers around the world. Applications may be simple to deploy on these platforms, but it is up to the user and the application to decide which regions and servers to use for application placement. Furthermore, network conditions and routing between the geo-distributed servers change over time, which can lead to sub-optimal performance of applications deployed on such servers. A user could either employ a static deployment configuration of servers, or attempt to use a more dynamic configuration. However,

Abstract:

Nous considérons, dans cette thèse, un nouveau service par lequel les opérateurs de télécommunications offrent des routes supplémentaires à leurs clients (en plus de la route par défaut) comme un service gratuit ou à valeur ajoutée. Ces routes supplémentaires peuvent être utilisées par des clients afin d’optimiser leurs communications, en outrepassant des points de congestion d’Internet, ou les aider à atteindre leurs objectifs d’ingénierie de trafic (meilleurs délais etc.) ou dans un but de robustesse. Nous proposons d’abord une architecture simple permettant à un opérateur de télécommunicati

Abstract:

To ensure that services can be delivered reliably and continuously over theInternet, it is important that both Internet routes and edge networks aresecured. However, the sophistication and distributed nature of many at-tacks that target wide-area routing and edge networks make it difficult foran individual network, user, or router to detect these attacks. Thereforecollaboration is important. Although the benefits of collaboration betweendifferent network entities have been demonstrated, many open questionsstill remain, including how to best design distributed scalable mechanismsto mitigate att

The aim of this master thesis is to create two laboratory exercises in ns-3 network simulator for chosen communication protocols. The chosen protocols are BGP and ICMPv6. The first part of this thesis contains teoretical knowledge used in order to design laboratory exercise. It contains descriptions of funcionality of both protocols and messages they use. This chapter also includes brief description of three options which were considered for implementation of BGP protocol into ns-3 enviroment. The second chapter consists of actual laboratory exercises which were created as a purpose of this th

Abstract:

The usage of technical equipment and the interconnection of all these devices has become essential to our every day life and to provide as good service as possible for the internet of today. However, many have the opportunity to inspect the data as it is being rushed across the globe to provide users with information at the press of a button. This study examines the routing patterns from hundred thousands of trace routes going from user to server around the globe. Using this trace data, we demonstrate not only the number of companies involved in data transfers on other continents then where th

Abstract:

Internet es una red de redes; para poder comunicarse, se debe encontrar un camino entre el emisor y el receptor. El protocolo más usado para encontrar caminos entre redes distantes es Border Gateway Protocol (BGP). Este protocolo se basa en la confianza, por lo que es vulnerable a ataques y a errores de configuración, además, estos errores se propagan rápidamente, pudiendo afectar una parte considerable de Internet. Por esto se hace necesario contar con herramientas que detecten estos problemas. Cada red se dice visible desde algún punto, si desde ese punto se puede enviar información hacia es

Les théâtres d’opérations militaires s’organisent aujourd’hui sous la forme de coalitions. Les forces armées qui sont déployées possèdent des moyens technologiques (communication, routage) et créent des réseaux sans fil. Le mouvement de ces forces sur le terrain donne au réseau une topologie fortement dynamique. Il se caractérise comme un réseau sans fil mobile, plus communément appelé MANET (Mobile Ad hoc NETwork). Pour l’efficacité de la mission et des communications, il est intéressant d’interconnecter facilement les différents groupes participant à la coalition. Cependant, chaque membre de

The models presented in this report are designed for handling various types of advanced multimedia applications and services when using the multicast communication paradigm. The architectural models presented in this thesis are independent of the routing protocols used as well as of the underlying networking environment. Several exiting challenges related to high bandwidth requirements, low network delay, and jitter are discussed together with t

Abstract:

A new approach to distributed network simulations that eases the burdens on the simulation developer in creating space-parallel simulations is presented. It provides a full-topology knowledge for every federate (simulator instance) to make the best routing decision to destinations simulated at other federates. Later, this technique was used to characterize the benefits of IP Anycast mechanism at large scale. Different IP Anycast scenarios were simulated in a detailed Border Gateway Protocol (BGP) simulator using a realistic large-scale AS topology. Results indicated that Anycast indeed pro
