Abstract:
The issue of converged networks is to ensure the sufficient quality of services along the entire length of the communication transmission. This issue is closely connected to the real-time services, such as VoIP (Voice over Internet Protocol) and videoconferencing. These services require strict adherence to quality parameters, otherwise their function is not guaranteed. This problem particulary resolves subsystem IMS (IP Multimedia Subsystem), which concluded on the basis of user profiles can provide the required quality of service. Therefore the theoretical part deals with the description of the structure of the system and protocols designed to signal the network. Various mechanisms to support quality of services in access and backbone networks are also described. The following section explains the principle of provision of quality requirements of end-user networks. In the practical part is this theoretical knowledge used for designing and configuration of the network consisting of various technologies. The resulting model is then simulated in Opnet Modeler program, which is used for designing and testing of packet networks. Each simulation shows the effect of mapping quality requirements in the different access network on technologies, which are supported in the backbone. The outcome of this work is detailed network analysis and comparison of mechanisms for implementing quality of service. The conclusion summarises all simulation outcomes.

Abstract:
The doctoral thesis is focused on a research in the area of the quality-of-service support technologies in data networks. The current modern communication networks cannot operate correctly without an effective tool allowing differentiated treatment for various network traffic classes. Looking at the current trends in this area it turns out that the technology of Differentiated services is currently the most widely used mechanism for QoS assurance in data networks. The major part of this doctoral thesis concerns the design of a novel QoS system which offers a solution for one of the main problems of DiffServ technology. This disadvantage lies in the missing cooperation between the end station and edge node of the DiffServ domain. To overcome this limitation the system proposed introduces an improvement which enables the user application to actively participate in the resource reservation process by direct configuration of the DSCP value in the IP header of its own packets. This functionality is based on the identification of DiffServ configuration parameters available in the edge router. To retrieve the information required from network component the well-known SNMP protocol has been chosen, which has direct access to the components’s configuration stored in the MIB database. On the basis of this theoretical proposal several simulation scenarios have been created and analysed. The results show that the system designed presents an efficient solution for the mentioned problem of DiffServ. They also give good assumptions for the successful implementation of this system into a real environment.

Abstract:
The exponential growth of Internet applications has created new challenges for the control and administration of large-scale networks, which consist of heterogeneous elements under dynamically changing traffic conditions. These emerging applications need guaranteed service levels, beyond those supported by best-effort networks, to deliver the intended services to the end user. Several models have been proposed for a Quality of Service (QoS) framework that can provide the means to transport these services. It is desirable to find efficient routing strategies that can meet the strict routing requirements of these applications. QoS routing is considered as one of the major components of the QoS framework in communication networks. In QoS routing, paths are selected based upon the knowledge of resource availability at network nodes and the QoS requirements of traffic. Several QoS routing schemes have been proposed that differ in the way they gather information about the network state and the way they select paths based on this information. The biggest downside of current QoS routing schemes is the frequent maintenance and distribution of global state information across the network, which imposes huge communication and processing overheads. Consequently, scalability is a major issue in designing efficient QoS routing algorithms, due to the high costs of the associated overheads. Moreover, inaccuracy and staleness of global state information is another problem that is caused by relatively long update intervals, which can significantly deteriorate routing performance. Localized QoS routing, where source nodes take routing decisions based solely on statistics collected locally, was proposed relatively recently as a viable alternative to global QoS routing. It has shown promising results in achieving good routing performance, while at the same time eliminating many scalability related problems. In localized QoS routing each source-destination pair needs to determine a set of candidate paths from which a path will be selected to route incoming flows. The goal of this thesis is to enhance the scalability of QoS routing by investigating and developing new models and algorithms based on the localized QoS routing approach. For this thesis, we have extensively studied the localized QoS routing approach and demonstrated that it can achieve a higher routing performance with lower overheads than global QoS routing schemes. Existing localized routing algorithms, Proportional Sticky Routing (PSR) and Credit-Based Routing (CBR), use the blocking probability of candidate paths as the criterion for selecting routing paths based on either flow proportions or a crediting mechanism, respectively. Routing based on the blocking probability of candidate paths may not always reflect the most accurate state of the network. This has motivated the search for alternative localized routing algorithms and to this end we have made the following contributions. First, three localized bandwidth-constrained QoS routing algorithms have been proposed, two are based on a source routing strategy and the third is based on a distributed routing strategy. All algorithms utilize the quality of links rather than the quality of paths in order to make routing decisions. Second, a dynamic precautionary mechanism was used with the proposed algorithms to prevent candidate paths from reaching critical quality levels. Third, a localized delay-constrained QoS routing algorithm was proposed to provide routing with an end-to-end delay guarantee. We compared the performance of the proposed localized QoS routing algorithms with other localized and global QoS routing algorithms under different network topologies and different traffic conditions. Simulation results show that the proposed algorithms outperform the other algorithms in terms of routing performance, resource balancing and have superior computational complexity and scalability features.

Abstract:
Hoy en día, entre los servicios más solicitados por los usuarios en las redes de comunicaciones, se encuentran aquellos que incorporan información multimedia. En Internet, es habitual que un gran número de páginas web incorporen imágenes, información de audio y en algunos casos, información de vídeo. Sin embargo, debido a que Internet sólo ofrece un servicio de entrega best-effort, la información audiovisual recibe el mismo tratamiento que el dispensado a cualquier otro tipo de datos poco sensibles al retardo temporal. Con el fin de desarrollar nuevos marcos de operación que permitan la diferenciación en el tratamiento de los servicios sobre redes basadas en IP, el IETF ha propuesto dos arquitecturas de red con calidad de servicio: IntServ y DifServ. De esta forma se pretende soportar adecuadamente la transmisión de flujos inelásticos de tasa variable mediante la ubicación de recursos especialmente dedicados al transporte de servicios con restricciones temporales acotadas. Actualmente, el tráfico de vídeo se transporta principalmente a través de canales de tasa binaria constante. Sin embargo, este tráfico es por naturaleza variable, con lo que la utilización de los recursos de red se vería sustancialmente mejorada utilizando canales de tasa variable.

En este trabajo se plantea el problema de la transmisión eficiente de tráfico de vídeocomprimido MPEG de tasa variable sobre redes IP con calidad de servicio. Para ello, en primer lugar se realiza un, estudio de los algoritmos de compresión más comúnmente utilizados en la actualidad. A continuación, se realiza un análisis detallado de las distintas alternativas para la transmisión de vídeo en redes IP. En primera instancia se ha descrito la problemática del transporte de vídeo en redes de conmutación de paquetes sin garantías de servicio, discutiendo la necesidad de la aplicación de técnicas de control de tasa y suavizado de tráfico.
Posteriormente se han introducido las nuevas arquitecturas IntServ y DiffServ especificadas para dar soporte a servicios con un nivel de calidad garantizado. Sobre estas arquitecturas se han discutido las posibles alternativas de transmisión de vídeo sobre redes IP con QoS y la adecuación de los esquemas de codificación de vídeo estandarizados que pueden ser aplicados sobre ellas.

A partir de este estudio se ha puesto de relieve la necesidad de la caracterización del tráfico de vídeo ya que requiere de elevados anchos de banda que además fluctúan ampliamente a lo largo de la conexión. La caracterización del tráfico se ha llevado a cabo a través del modelado MMFP bidimensional de los flujos de vídeo VBR a nivel de GoP. El estudio se ha realizado con un amplio conjunto de secuencias codificadas VBR con diferentes niveles de calidad y resolución espacial. Los resultados han demostrado la aplicabilidad de este modelo de forma general sobre cualquier secuencia de vídeo con independencia de su resolución o nivel de degradación introducido en el proceso de codificación. Una de las principales contribuciones al modelado de estos servicios ha sido el desarrollo de una metodología de ajuste de los parámetros del modelo MMFP bidimensional que permite una automatización del proceso de caracterización del tráfico de vídeo.

Una vez se ha alcanzado un conocimiento de comportamiento del tráfico de vídeo de calidad de imagen constante, se ha abordado su transmisión sobre redes IP con QoS. El marco de trabajo contempla la aplicación de mecanismos de renegociación y de asignación dinámica de recursos. El trafico de vídeo detasa variable es un ejemplo claro en el que un sistema de renegociaciones maximiza la eficiencia de los recursos de red. La gran variabilidad de tasa binaria exhibida por este tipo de tráfico y su grado de persistencia hacen apropiada la aplicación de técnicas de segmentación sobre las secuencias de vídeo. En este trabajo se han analizado diferentes esquemas de renegociación y se ha estudiado su aplicabilidad en el contexto de redes IP con QoS y facilidades de renegociación de recursos por conexión. Se han analizado las técnicas "Work-ahead buffering" donde se explota intensivamente el buffer del cliente para almacenar datos enviados "por adelantado". El estudio ha permitido derivar una nueva propuesta denominada 2-RCBR. Complementariamente, se ha derivado una nueva técnica de segmentación basada en el modelo MMFP bidimensional analizado, obteniéndose un esquema de segmentación genérico e independiente de la resolución y del factor de cuantificación utilizado ella codificación de las secuencias. Este método, que se ha denominado método de los umbrales genéricos, permite desarrollar una segmentación de una secuencia de vídeo de forma extraordinariamente simple con un elevado nivel de eficiencia. Por otro lado, teniendo en cuenta que se desea fijar una cota máxima del retardo extremo a extremo durante el servicio de video streaming, se ha propuesto una nueva técnica de segmentación basada en el retardo máximo aceptado, garantizando un retardo máximo dentro de la red IP para cada segmento transmitido.


La última parte del trabajo ha desarrollado la arquitectura de transmisión escalada sobre redes IP. A raíz de los excelentes resultados obtenidos hasta el momento, se ha procedido a aplicar la misma metodología para la codificación escalable. Se ha caracterizado el flujo escalable de tasa variable mediante el modelo MMFP bidimensional y se han aplicado las técnicas de segmentación propuestas anteriormente. Los resultados obtenidos han seguido el comportamiento esperado, pudiéndose considerar satisfactorios.

Abstract:
L'objectif de cette thèse est l'étude des technologies de gestion de la qualité de service (QoS) dans les réseaux IP et CORBA. CORBA est de nos jours la spécification la plus complète d'un middleware pour l'implantation des applications distribuées orientées objet. Les technologies pour la gestion de la QoS comprennent des services, des protocoles et des architectures. La spécification CORBA inclut des services et des architectures pour l'implantation des applications avec des contraintes de temps (c'est la spécification RTCORBA) et des exigences en QoS. Cependant, bien qu'ils puissent être complémentaires, CORBA et les technologies IP pour la QoS (IP-QoS) ont été développés de façon séparée. Dans ce travail, nous proposons des architectures pour l'interaction de technologies IP-QoS (notamment RSVP, IntServ, DiffServ et MPLS) et CORBA, nous proposons une architecture pour la spécification de profils CORBA, ces profils ont pour but le développement des applications distribuées temps réel, au travers des capacités fournies par CORBA, tout en économisant les ressources du système

Abstract:
Ces dernières années, les évolutions de linformatique et des télécommunications ont conduit à une modification drastique du paysage de la communication informatique, et en conséquence de lInternet et de ses services : les applications sont désormais à la fois multimédias, multi utilisateurs et coopératives ; les technologies réseaux offrent à présent de hauts débits de transmission, à échelle locale ou grande distance, et permettent de se connecter à lInternet via différents types de terminaux et de points daccès, filaires ou sans fil. En dépit de ces avancées, les services de communication offerts par lInternet sont encore très insuffisants, en ceci quils noffrent aucune garantie sur les performances offertes, notamment en termes de délai de bout en bout. Cest dans cette problématique que sinscrivent nos travaux, qui adressent le besoin de nouveaux services, protocoles et architectures de communication pour lInternet, dans le but doffrir des garanties de Qualité de Service (QdS). Notre démarche part dune expression formelle des besoins applicatifs et aboutit à des solutions de bout en bout visant à : (1) intégrer les niveaux considérés (Application, Transport et IP) ; (2) minimiser lutilisation des ressources (bande passante, buffer, &) ; et (3) abstraire le niveau applicatif de la complexité du choix et du paramétrage des services sous-jacents. Trois thèmes de recherche sont explorés : (1) les services et protocoles de Transport multimédia pour optimiser la QdS dans un contexte IP de type Best Effort ; (2) les architectures de bout en bout pour garantir la QdS, en coordonnant les nouveaux services de lInternet aux niveaux Transport et IP (IntServ et DiffServ mono puis multi domaines) ; et (3) la signalisation pour la QdS, dans un contexte IP de type DiffServ multi domaines. Notre prospective concerne dune part la signalisation pour la QdS en considérant à présent lhétérogénéité de lInternet multi domaines, et dautre part, les protocoles de Transp ort auto configurables et les architectures dynamiques, pour optimiser la qualité des communications et des coopérations dans les futurs réseaux ambiants (réseaux mobiles et ad hoc, capteurs, &) en tenant compte dune dynamicité du contexte à la fois au niveau utilisateur, mobile et coopérant, et au niveau du réseau, mobile et aux ressources variables. null null

It is commonly believed that Integrated Service (IntServ) is not scalable to large networks. In this thesis, we study the association of Multiprotocol Label Switching (MPLS) and IntServ to try to overcome the scalability problem. The goal is to provide Quality of Service (QoS) in an efficient and scalable manner in the Internet through enable Label Switching Routers (LSRs) to be able to identify the appropriate reservation state for the aggregated IntServ flows based on the corresponding label. IntServ data flows are aggregated and mapped to one data flow in the MPLS network. IntServ data flows belong to the same Forwarding Equivalence Class (FEC) are aggregated. The proposed scheme of integration of IntServ and MPLS is efficient and scalable. Efficiency implies that when flow aggregation is employed, one can use less resource to achieve the same required QoS, and less time is spent in transmitting packets. Scalability means that the aggregation of IntServ flows makes IntServ works well even when the volume of the data flow becomes huge. Controlled-load service and guaranteed service are two service types of IntServ. According to the different characteristic of these two services, First Come First Serve (FCFS) and the Rotating Priority Queue+ (RPQ+) packet scheduling are employed for aggregated controlled-load and guaranteed-service flows, respectively. The Taiwan Academic Network (TANet) and very High Speed Backbone Network Service (vBNS) are used as our simulation environments. Simulation results show that because of flow aggregation, more flows could be served meanwhile the scalability problem of IntServ is also mitigated.

Abstract:
The evolution of Internet and its successful technologies has brought a tremendous growth in business, education, research etc. over the last four decades. With the dramatic advances in multimedia technologies and the increasing popularity of real-time applications, recently Quality of Service (QoS) support in the Internet has been in great demand. Deployment of such applications over the Internet in recent years, and the trend to manage them efficiently with a desired QoS in mind, researchers have been trying for a major shift from its Best Effort (BE) model to a service oriented model. Such efforts have resulted in Integrated Services (Intserv), Differentiated Services (Diffserv), Multi Protocol Label Switching (MPLS), Policy Based Networking (PBN) and many more technologies. But the reality is that such models have been implemented only in certain areas in the Internet not everywhere and many of them also faces scalability problem while dealing with huge number of traffic flows with varied priority levels in the Internet. As a result, an architecture addressing scalability problem and satisfying end-to-end QoS still remains a big issue in the Internet. In this chapter the authors propose a policy based architecture which they believe can achieve scalability while offering end to end QoS in the Internet.

Abstract:
Currently the Internet offers a point-to-point delivery service, which is based on the “best effort” delivery model. In this model, data will be delivered to its destination as soon as possible, but with no commitment about bandwidth or latency. Using protocols such as the Transmission Control Protocol (TCP), the highest guarantee the network provides is reliable data delivery. This is adequate for traditional data applications like e-mail, web browsing, File Transfer Protocol (FTP) and Telnet, but inadequate for applications requiring timeliness. For example, multimedia conferencing or audio and video streaming applications, which require high bandwidth capacity and are sensitive to delay and delay variation. For these applications to perform adequately, Quality of Services (QoS) must be quantified and managed, and the Internet must be modified to support real-time QoS and controlled end-to-end delays. The efforts to enable end-to-end QoS over the Internet Protocol version 4 (IPv4) networks have led to the development of two different architectures, the Integrated services architecture (Intserv) and the Differentiated services architecture (Diffserv), which although different, support services that go beyond the best effort service. This chapter will present a detailed discussion on these IPv4 quality of services models. First, the Integrated services architecture with its related issues such as the reservation setup protocol will be demonstrated. Second, the Differentiated services architecture with a description of the services they provide will be described. Finally, a comparison between the Best-effort, the Integrated and Differentiated services will be done.
