    Network virtualisation is a promising technique for a better future Internet by allowing for network resource sharing. However, resource sharing requires that virtual nodes and links be embedded onto substrate nodes and links (virtual network embedding), and thereafter the allocated resources dynamically managed throughout the lifetime of the virtual network (dynamic resource allocation). Since the constrained virtual network embedding problem is NP¿Hard, many existing approaches are not only static, but also make simplifying assumptions, most of which would not apply in practical environments. This PhD research proposes improvements to both virtual network embedding and dynamic resource allocation. The objective is to achieve an efficient utilisation of physical network resources. To this end, we propose a path generation-based approach for a one-shot, unsplittable flow virtual network embedding, and a reinforcement learning-based dynamic allocation of substrate network resources.

    In this paper we face the challenge of designing self-tuning systems governing the working parameters of base stations on a mobile network system to optimize the quality of service and the economic benefit of the operator. In order to accomplish this double objective, we propose the combined use of fuzzy logic and reinforcement learning to implement a self-tuning system using a novel approach based on a two-agent system. Different combinations of reinforcement learning techniques, on both agents, have been tested to deduce the optimal approach. The best results have been obtained applying the Q-learning technique on both agents, clearly outperforming the alternative of using non-learning algorithms.

    A new era in telecommunications is emerging. Virtualized networking functions and resources will offer network operators a way to shift the balance of expenditure from capital to operational, opening up networks to new and innovative services. This article introduces the concept of edge as a service (EaaS), a means of harnessing the flexibility of virtualized network functions and resources to enable network operators to break the tightly coupled relationship they have with their infrastructure and enable more effective ways of generating revenue. To achieve this vision, we envisage a virtualized service access interface that can be used to programmatically alter access network functions and resources available to service providers in an elastic fashion. EaaS has many technically and economically difficult challenges that must be addressed before it can become a reality; the main challenges are summarized in this article.

    Network virtualisation has received attention as a way to allow for sharing of physical network resources. Sharing resources involves mapping of virtual nodes and links onto physical nodes and links respectively, and thereafter managing the allocated resources to ensure efficient resource utilisation. In this paper, we apply artificial neural networks for a dynamic, decentralised and autonomous allocation of physical network resources to the virtual networks. The objective is to achieve better efficiency in the utilisation of substrate network resources while ensuring that the quality of service requirements of the virtual networks are not violated. The proposed approach is evaluated by comparison with two static resource allocation schemes and a reinforcement learning-based approach.

    This position paper presents SoftINTERNET an initiative for a service-aware and management-aware network control infrastructure for heterogeneous networks (i.e., wired and wireless) that uses software driven features for the elaboration, development, and validation of networking concepts. The proposed infrastructure aims to optimally integrate the connectivity and management layers. It operates across multiple network environments and on top of private and public network clouds utilising fixed and mobile virtual resources, OpenFlow enabled network devices like switches and routers, and networks of Smart Objects. In this position paper, we discuss the motivation, architecture and research challenges for such a promising concept.

    In recent years, various network virtualization techniques have been proposed for flexibly supporting heterogeneous services over virtual network platforms. However, systematic views on how virtual network resources (VNRs) can be practically managed in such open environments has been missing till now. To fill the gap, we present in this article a two-dimensional architecture for end-to-end VNR management from distinct viewpoints of service providers and network providers. The horizontal dimension of VNR management allows SPs to bind VNRs rented from heterogeneous NPs to form unified end-to-end service delivery platforms. The vertical dimension of VNR management enables NPs to perform cost-efficient allocation of VNRs to requesting SPs, but without necessarily forcing themselves to collaborate with each other. Such a VNR management architecture will complement existing network virtualization platforms in accelerating the realization of virtual resource sharing in the future Internet business marketplaces.

    We study a load balancing strategy, based on the price offered by the base stations to the end-users who are willing to establish a connection. The proposed scheme is compared with a pure load balancing procedure, in a scenario comprising two different operators.We study the impact of modifying the price offered by the base stations, in terms of the achieved load balancing, as well as considering the revenue obtained by the operators. Furthermore, we also enhance the two former access selection schemes, by incorporating the willingness of reducing the number of handovers, so as to analyze the impact over this particular parameter, and over all the previous results. The whole work is conducted over a proprietary event-based simulation tool, which offers the required degree of flexibility and low computational overhead.

    Next generation networks and service providers are rapidly evolving in order to satisfy the demands of an increasing number of users. Nowadays, one of the most relevant research lines in the Heterogeneous Wireless Access Networks realm is the use of procedures and mechanisms so as to provide intelligence to the network, with the main goal of optimizing its performance. Furthermore, mobile communication users are becoming more demanding, and thus it becomes essential for the providers to be able to offer a competitive value for money. This paper pursues the objective of obtaining, from an analytical perspective, the optimum price assignment strategy according to the characteristics of a particular scenario, analyzing the improvement attained with such optimum pricing policy as compared to a more traditional one. Game theory techniques, which are gathering the interest within the communications scientific community, are used for the analysis.

    Virtualization enables the building of multiple virtual networks over a shared substrate. One of the challenges to virtualisation is efficient resource allocation. This problem has been found to be NP hard. Therefore, most approaches to it have not only proposed static solutions, but have also made many assumptions to simplify it. In this paper, we propose a distributed, autonomic and artificial intelligence based solution to resource allocation. Our aim is to obtain self-configuring, self-optimizing, self-healing and context aware virtual networks

    One of the key aspect fundamentally missing from the current Internet infrastructure is an advanced service networking platform and facilities, which take advantage of flexible sharing of available connectivity, computation, and storage resources. This paper aims to explore the architectural co-existence of new and legacy services and networks, via virtualisation of connectivity and computation resources and self-management capabilities, by fully integrating networking with cloud computing in order to create In-Network Clouds. It also presents the designs and experiments with a number of In-Network Clouds platforms, which have the aim to create a flexible environment for autonomic deployment and management of virtual networks and services as experimented with and validated on large-scale testbeds.

    This article presents a service-centric orchestration protocol for self-interested autonomic management systems that supports the coalition formation process in largescale collaborative and competitive environments. It supports environments in which coalition formations are carried out targeting multiple service requests at the same time, and in which the autonomic management systems compete to work in the most appropriate coalition. The protocol exploits the benefits of social networking in favor of manageability and scalability. Its performance is analyzed taking into account crucial aspects of self-organizing systems such as stability and convergence to optimal coalition formation results.

    The recent years saw an evolution of Grid technologies from early ideas to production deployments. At the same time, the expectations for Grids shifted from idealistic hopes - buoyed by the successes of the initial testbeds - to disillusionment with available implementations when applied to large-scale general purpose computing. In this paper, we argue that a mature e-Infrastructure aiming to bridge the gaps between visions and realities cannot be delivered without introducing Service Level Management (SLM). To support this thesis, we present an analysis of the Grid foundations and definitions that shows that SLM-related ideas were incorporated in them from the beginning. Next, we describe how implementing SLM in Grids could improve the usability and user-experience of the infrastructure - both for its customers and service providers. We also present a selection of real-life Grid application scenarios that are important for the research communities supported by the Grid, but cannot be efficiently supported without the SLM process in place. In addition, the paper contains introduction to SLM, a discussion on what introducing SLM to Grids might mean in practice, and what were the current efforts already applied in this field. © 2012 Springer-Verlag Berlin Heidelberg.

    Our cities are already covered by a myriad of diverse wireless access networks. The most ubiquitous access networks are the well organized homogeneous and centralized operator-based cellular networks that sustain their business model on a captive client basis. However, a new billing paradigm is rising, where a client can choose to connect to the provider that best comply with his/her current requirements and context. Inside this paradigm, this paper presents a distributed, rule-based pricing strategy aimed to improve the quality of service and to increase the global income of a service provider. The performance and reliability of the rule-based decisions is supported by a Finite State Transducersbased inference machine specially designed to manage networking systems. We show, with simulations, that, using our strategy, the operators can make the new billing paradigm profitable while the clients benefit from the economic advantages of competition and of the quality given by a pricing–based network balance mechanism.

    La irrupción de nuevos servicios, y el imparable aumento del número de tecnologías de acceso a disposición de los usuarios, hace que los diferentes actores involucrados en el ámbito de las comunicaciones tengan que replantearse sus estrategias tradicionales. Es necesario afrontar el diseño de una arquitectura capaz de asumir los retos que van apareciendo, siendo clave romper con algunas de las soluciones tradicionales, que no son capaces de responder a las nuevas exigencias que aparecen. Uno de los aspectos más importantes es afrontar el diseño desde un punto de vista global, haciendo que las diferentes entidades cooperen entre sí de manera abierta y flexible, lo que no es posible (en muchas ocasiones) con parches a las alternativas que actualmente existen. Este marco es en el que se sitúa el proyecto Comunicaciones Cognitivas, Cooperativas y Gestión Autónoma de Servicios (C3SEM), que se fundamenta en la cooperación e integración del substrato de comunicación subyacente con la arquitectura de gestión de servicios. En este trabajo se plantea una de las líneas de trabajo actuales, en la que se analiza diferentes políticas de gestión de precios, ya que parece razonable que en el medio plazo los operadores se vean obligados a redefinir sus estrategias actuales, principalmente basadas en tarifas planas.

    We present an approach for deploying and subsequently managing a virtual network overlay, which is tailored to an end-user’s request. Our approach combines a binary integer optimisation process to decide on the number and placement of virtual routers, and an autonomic network management system that subsequently manages the configuration of the running virtual network. High-level optimisation policies are used to guide the optimisation process to identify a virtual network that favours lower hosting costs or higher network quality (we use mean delays as a quality metric). Low-level deployment policies are generated and used to govern the deployment and management of the virtual networks. Our results indicate that the binary integer optimisation process produces a virtual network that has lower cost as compared to creating a network based on combined shortest paths.

    The Autonomic Internet project [1] approach relies on abstractions and distributed systems of a five plane solution for the provision of Future Internet Services (OSKMV): Orchestration, Service Enablers, Knowledge, Management and Virtualisation Planes. This paper presents a practical viewpoint of the manageability of virtual networks, exercising the components and systems that integrate this approach and that are being validated. This paper positions the distributed systems and networking services that integrate this solution, focusing on the provision of Future Internet services for self-configuration and selfperformance management scenes

    The current Internet does not enable easy introduction and deployment of new network technologies and services. This paper aims to progress the Future Internet (FI) by introduction of a service composition and execution environment that re-use existing components of access and core networks. This paper presents essential service-centric platforms and software systems that have been developed with the aim to create a flexible environment for an Autonomic Internet.

    Several intra- and inter-domain quality of service (QoS) provisioning mechanisms for IP networks have been researched and developed using Differentiated Services (DiffServ) technology. However, the incremental efforts needed to manage DiffServ networks from a business-oriented viewpoint have received relatively little attention. This paper addresses this gap and presents a framework for achieving business-driven QoS provisioning in DiffServ over MPLS networks. We provide a rich model of SLA and business indicators as well as reasonable mapping functions that define, with key degrees of importance, the impact of business indicators over service management policies. Business and service indicators are used to control static and dynamic admission of services. The paper advances the state of the art by considering the influence of business-level objectives on the policy refinement process. We evaluate and discuss the effectiveness of our approach through a simulation environment that we developed over OPNET.

    This paper presents a SNMP-based Monitoring Agents for Multi-Constrain Resource Scheduling in Grids (SBLOMARS) as an effective solution for resource usage monitoring in virtual network environments. SBLOMARS is different to current large-scale distributed monitoring systems in three essential aspects: Firstly, it reaches a high level of generality by the integration of the SNMP protocol and thus, facilitates to handle heterogeneous operating platforms. Secondly, it is able to self-configure the polling periods of the resources to be monitored depending of network context and finally, it makes use of dynamic software structures to interface with third parties, allowing to be deployed in a wide range of devices, from simple mobile access devices to robust multiprocessor systems or clusters with even multiple hard disks and storage partitions. SBLOMARS has been deployed in EmanicsLab, a virtual laboratory constituted by fourteen nodes distributed in seven European Universities. Although the research is not yet concluded, available results confirm its suitability to deal with the challenges of monitoring virtual networks.

    This paper presents a new autonomic management architectural model consisting of a number of distributed management systems running within the network, which are described with the help of five abstractions and distributed systems: Virtualisation, Management, Knowledge, Service Enablers and Orchestration Planes. The envisaged solution is applicable to the management design of Future Internet as a service and self-aware network, which guarantees built-in orchestrated reliability, robustness, context, access, security, service support and self-management of the communication resources and services
