It is widely accepted that the network of the future will require a greater degree of service awareness and optimal use of network resources. This article presents an architectural design for an open software-defined network infrastructure that enables the composition of fast and guaranteed services in an efficient manner and the execution of these services in an adaptive way, taking into account better shared network resources provided by network virtualization. Validation results are provided with special emphasis on service deployment scalability over virtualized network infrastructures.Peer ReviewedPostprint (published version
International audienceThe 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
Existing services require assurable end to-end quality of service, security and reliability constraints. Therefore, the networks involved in the transport of the data must cooperate to satisfy those constraints. In a next generation Internet, each of those networks may be managed by different entities. Fur thermore, their policies and service level agreements (SLAs) will differ, as well as the autonomic management systems controlling them. In this context, we in the Autonomic Internet (AutoI) consortium propose the Orchestration Plane (OP), which promotes the interaction among different Autonomic Management Systems (AMSs). The OP mediates the communication and negotiation amongAMSs, ensuring that their SLAs and policies meet the requirement needed for the provisioning of the services. It also simplifies the federation of domains and the distribution of new services in virtualised network environments.Peer ReviewedPostprint (author’s final draft
Abstract-This paper presents a SNMP-based Monitoring Agents forMulti-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.

Abstract. This paper presents a framework to control the life cycle of enforceable policies aligned to business directives. The framework relies on three main aspects: the formalization of measurable business indicators underpinning the management cycle of policies, a holistic approach to conceal Quality of Service delivery with business alignment, and the use of policy-based management as the vehicle to control system behavior accordingly. The core contribution of this research lies in the network management area whose most widespread solutions for QoS delivery have been systematically decoupled from business value, although the research community recognizes business profit as the main motivation for any management solution. The ultimate goal of this research is to develop a management framework that allows exploiting business value in telecommunications infrastructures. As each application domain may have intrinsic peculiarities we propose to validate our approach in the context of DiffServ networks. Simulations will be conducted to evaluate and to optimize the performance of diverse business directives under different patterns of service invocations and patterns of inter-domain traffic exchange between autonomous systems. To the best of our knowledge no other approach has dealt with the above research area in such a holistic view.
