The simplicity of Internet design has led to enormous growth and innovation. In recent decades several network technologies, services and applications have appeared, which demand specific network requirements for their correct operation. In traditional networks, operators are responsible for providing a network configuration sufficiently robust to deal with a wide range of network events and applications. To achieve this is incredibly difficult because: i) the state of the networks can change continuously and today's networks do not provide a mechanism to automatically respond to the wide range of events that may occur and ii) the static nature of current network devices does not permit detailed control-layer configuration, given that the hardware and software are provided by the manufacturer and can not be customized. This is the basis of the current, present-day Internet and its architecture, that has grown in an evolutionary fashion from experimental beginnings, rather than from a deliberate strategy. The unpredictable network growth in terms of size and heterogeneity, has exposed a number of fundamental complexities in the current architecture. For instance, the manual configuration of control functions on network devices that may lead to misconfigurations. This is evident that network management requires more intelligent and efficient management systems to coordinate thousands of network elements and applications, the high demand on network performance and growing configuration complexity. In recent decades, several approaches have been introduced in order to improve the network management, such as: MPLS, virtualization and programmable networks. These latter networks have been proposed as a way of facilitating network evolution. In particular, Software Defined Networking (SDN), a networking paradigm focused on allowing software developers to rely on network resources in an easy manner, unifying the state network distribution and a general-purpose technique to manage any type of network in an transparent manner. In SDN, ¡etwork intelligence is logically centralized in software-based controllers (the control layer), and network devices become simple packet forwarding devices (the data layer) that can be programmed via an open interface. By decoupling the control and data layers, network devices can be easily programmed and reconfigured, allowing the behaviour of different types of network devices to be unified. Even though SDN is quite recent, it has already been standardized and implemented in the Internet by several recognized companies such as Google. Several SDN architectures have been proposed to handle current and future network services. However, there are still important research challenges to be addressed in SDN. Some of these current challenges are related to: i) SDN scalability as control is centralized, ii) control layer robustness as any failure can lead to switches to be disconnected from the controller, iii) consistency of network information as wrong decisions can be made affecting network performance and iv) security as controllers can be attacked. The purpose of this thesis is to address the first three of the aforementioned problems. They are addressed from the first premise, ignoring existing approaches offered in traditional networks to remedy some of these issues. First, a controller placement protocol is proposed, taking into account the network/service requirements. To measure the robustness of a control layer, a robustess metric is designed and evaluated. This metric can also be used to select controller placements in a SDN network that minimize the data loss. Finally, a resource discovery protocol is designed, implemented and evaluated. This protocol discovers any network topology in time efficient, avoiding making assumptions about the network state as it happens in traditional networks.

Das Datenverkehrsaufkommen in Rechenzentren wächst stetig an. Die weit ver- breiteten Round-Robin Verfahren können dieses Aufkommen nicht mehr bewältigen, da diese die Last ungleich verteilen. Manuelle Planung und Umverteilung, auch Traffic Engineering genannt, lindert dieses Problem und wird vielfach in Weitverkehrsnetzwerken (WANs) eingesetzt. Der hohe manuelle Aufwand und die damit verbundenen Kosten, als auch die Kosten für spezielle Hardware, ma- chen Traffic Engineering in Rechenzentren jedoch unpraktikabel. Diese Dissertation beschäftigt sich mit der Frage, ob Software-Defined Networ- king (SDN) genutzt werden kann, um Traffic Engineering im Rechenzentrums- umfeld praktikabel zu gestalten. Um dieses Ziel zu erreichen, muss der manuelle Aufwand minimiert werden und die Anforderungen an die Hardware reduziert werden. Dafür zeige ich zunächst in dieser Arbeit, dass SDN es ermöglicht Label Switching, das bessere Verteilung der Flüsse ermöglicht, ohne spezielle Hardware zu realisieren. Ich stelle ich SynRace vor, welches SDN mit Testpaketen kombiniert, um den Status des Netzwerkes besser beobachten zu können. Darüber hinaus, wird as GlobalFib Framework eingeführt, welches SDN Anwendungen erlaubt, direkt ihre Bedarfsanforderungen an eine zentrale Stelle zu melden. Diese Ansätze erlauben die Verteilung der Flüsse zu automatisieren. Wenn mehrere SDN Anwendungen im gleichen Netzwerk ausgeführt werden und versuchen, gleichzeitig ihre Anforderungen und Regeln durchzusetzen, sind Konflikte unausweichbar. In dieser Arbeit analysiere ich die Art dieser Konflikte und Möglichkeiten, mit diesen umzugehen. Der NetIDE core implementiert diese Konfliktbehandlung und die dynamische Konfiguration des Netzwerkes. - Traffic demands in data centres are steadily increasing. Simple, yet commonly used round-robin algorithms are notable to meet these demands since they distribute the demands unevenly. Manually planning and redistribution, also called traffic engineering (TE), alleviates this problem. Traffic engineering is common in wide area networks (WANs). The high amount of manual workand associated cost in special hardware makes traffic engineering unpractical in data centre networks. This thesis looks into the question whether software-defined networking (SDN) can be used to bring traffic engineering to the data centre. To reach this goal, the amount of manual labour and requirements for hardware need to be reduced. I first show that label switching, which enables better traffic distribution, is possible withSDN without special hardware. I present SynRace that infers network status by combining probes with SDN. The GlobalFIB framework allows applications to report directly their demands to a central instance. Both allow traffic redistribution to be automated. With running multiple SDN application on the network and trying to fulfil all their demands and rules, conflicts are inevitable. In this thesis I analyse the nature of these conflicts and possibilities to handle them. The NetIDE core implements this conflict resolution and dynamic reconfiguration of the network.
