Abstract:
This master’s thesis explains why certain network services are difficult to provision and configure using IT automation and cloud orchestration software. An improvement is proposed and motivated. This proposed improvement enables network operators to define a set of data models describing how to provision and interconnect a set of Virtual Network Functions (VNFs) (and possibly existing physical network functions) to form networks. Moreover, the proposed solution enables network operators to change the configuration at runtime. The work can be seen as a step towards self managing and auto scali

Abstract:
NFV is an emerging network architecture to increase flexibility and agility within operator's networks by placing virtualized services on demand in Cloud data centers (CDCs). One of the main challenges for the NFV environment is how to efficiently allocate Virtual Network Functions (VNFs) to Virtual Machines (VMs) and how to minimize network latency in the rapidly changing network environments. Although a significant amount of work/research has been already conducted for the generic VNF placement problem and VM migration for efficient resource management in CDCs, network latency among variou

Network Function Virtualization (NFV) is a promising technology that proposes to move packet processing from dedicated hardware middle-boxes to software running on commodity servers. As such, NFV brings the possibility of outsourcing enterprise Network Function (NFs) processing to the cloud. However, for a Cloud Service Provider (CSP) to offer such services, several research problems still need to be addressed. When an enterprise outsources its NFs to a CSP, the CSP is responsible for deciding: (1) where initial Virtual NFs (VNFs) should be instantiated, and (2) what, when and where addition

Abstract:
Mestrado em Engenharia de Computadores e Telemática<br>This dissertation provides a way to merge Cloud Computing infrastructures with traditional or legacy network deployments, leveraging the best in both worlds and enabling a logically centralized control for it. A design/architecture is proposed to extend existing Cloud Computing software stacks so they are able to manage networks outside the Cloud Computing infrastructure, by extending the internal, virtualized network segments. This is useful in a variety of use cases such as incremental Legacy to Cloud network migration, hybrid virt

Abstract:
Doutoramento em Engenharia Informática<br>The proliferation of Internet access allows that users have the possibility to use services available directly through the Internet, which translates in a change of the paradigm of using applications and in the way of communicating, popularizing in this way the so-called cloud computing paradigm. Cloud computing brings with it requirements at two different levels: at the cloud level, usually relying in centralized data centers, where information technology and network resources must be able to guarantee the demand of such services; and at the ac

Актуальність: Підвищення якості функціонування мереж зв'язку за рахунок поліпшення надійності є складною науково-технічною та економічною проблемою. Це обумовлено тим що до мереж з новими технологіями, таким як програмно-конфігуровані мережі (SDN) в даний час висувають високі вимоги по надійності (відмовостійкості) в тому числі до характеристик відновлення мережі після відмови. При розробці заходів, що підвищують надійність доцільна постановка задачі максимально можливого підвищення якості функціонування мережі при мінімальному часу відновлення зв'язку.

Passive optical networks (PONs) promise to solve these problems by providing a better service to users and providers. PON networks are very attractive since they don't depend on active elements between their end points, leading to lower

Abstract:
Questo documento si interroga sulle nuove possibilità offerte agli operatori del mondo delle Reti di Telecomunicazioni dai paradigmi di Network Functions Virtualization, Cloud Computing e Software Defined Networking: questi sono nuovi approcci che permettono la creazione di reti dinamiche e altamente programmabili, senza disdegnare troppo il lato prestazionale. L'intento finale è valutare se con un approccio di questo genere si possano implementare dinamicamente delle concatenazioni di servizi di rete e se le prestazioni finali rispecchiano ciò che viene teorizzato dai suddetti paradigmi.

La virtualisation est une tentative prometteuse pour résoudre certains défis de la 5G. La virtualisation consiste à exécuter des fonctions réseaux en tant que logiciels sur une infrastructure physique partagée. Cela optimise les coûts de déploiement et simplifie la gestion, mais il introduit de nouveaux défis tels que la topologie de réseau dynamique et le manque de visibilité. Dans cette thèse, nous proposons un algorithme d’auto-modélisation et un processus de diagnostic actif pour relever ces défis. Nous apprenons et validons le modèle défini par injection de pannes.
