Abstract

El presente anteproyecto de “Desdoblamiento del tramo final de la línea Castellbisbal-Mollet del pK 23,2 al pK 27,3 y nueva estación de Mollet-Sant Fost” nace con el objetivo de llevar a cabo las actuaciones necesarias para dotar a una infraestructura básica como es la línea de ferrocarril Castellbisbal-Mollet de doble vía en toda su traza. Actualmente, la ausencia de doble vía en el tramo final causa graves interferencias con el servicio del Corredor del Mediterráneo y la línea de cercanías C2 Vilanova – Barcelona - Maçanet, al existir cizallamientos en las vías principales.

155. Providing Reliable Services over Wireless Networks Using a Low Overhead Random Linear Coding Scheme.

Abstract

In this work, we propose a novel intra-flow network coding solution, which is based on the combination of a low overhead Random Linear Coding (RLC) scheme and UDP, to offer a reliable communication service. In the initial protocol specification, the required overhead could be rather large and this had an impact over the observed performance. We therefore include an improvement to reduce such overhead, by decreasing the header length. We describe an analytical model that can be used to assess the performance of the proposed scheme. We also use an implementation within the ns-3 framework to assess the correctness of this model and to broaden the analysis, considering different performance indicators and more complex network topologies. In all cases, the proposed solution clearly outperforms a more traditional approach, in which the TCP protocol is used as a means to offer a reliable communication service. [ABSTRACT FROM AUTHOR]

156. Data on Retention

Abstract

Proposed EU regulations on data retention could require every provider to keep accounting logs of its customers' Internet usage. Although the technical consequences of these requirements have been investigated by consultancy companies, this paper investigates what this accounting data could be, how it can be obtained and how much data storage is needed. This research shows that every gigabyte of network traffic results in approximately 400 kilobyte of accounting data when using our refinements to existing methods for storing accounting data – less by a factor twenty than previously assumed.

Abstract

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.

181. A dynamic pricing algorithm for a network of virtual resources.

Abstract

A service function chain (SFC) is an ordered combination of abstract network functions (eg, network address translation and a firewall) that together define a network service (eg, video on demand). In an SDN/NFV-based architecture, SFCs are composed of virtual network functions that need to be mapped to physical network components. Because the mapping of an SFC may be possible by multiple competing infrastructure providers (InPs), price will be a key differentiating factor. The pricing algorithm is therefore essential towards revenue management, yet current static pricing approaches suffer from several limitations. Among others, they do not consider the characteristics of the requests or the current state of the physical network. Using historical data, market data, and the current state of the physical network we investigate whether it is possible to increase total revenue of an InP compared to traditional static pricing approaches. This paper proposes a dynamic pricing algorithm to determine (1) at which utilization level it is rewarding to charge a higher price for a particular resource and (2) the alternative price that should be charged. Our simulation results for 8 different setups show that the proposed heuristic outperforms a static pricing approach significantly (by 8-85% points for the considered scenarios). As a consequence, the proposed approach can be considered as an alternative for static pricing approaches. Still, it is unclear how the total revenue of an InP is affected when multiple or all competitors use a dynamic pricing algorithm; this will therefore remain the focus of future work.

184. Autonomic system for mobility support in 4G networks

Author

Mapp, Glenford E., Baliosian, Javier, Serrat, Joan, Vidales, Pablo, Mapp, Glenford E., Baliosian, Javier, Serrat, Joan, and Vidales, Pablo

Abstract

The paper is about PROTON, a reactive policy management system developed to set up policies to decide when vertical handover should occur, based on a 3-layer subsystem. This work is significant because it showed that PROTON could not be run on the mobile node. The paper proposed running PROTON in the network that would then specify a finite-state machine (i.e. an autonomic system) to execute on the mobile. The work is significant because it showed that autonomic techniques can be used in 4G systems to support client-based handover. It is also a tremendously useful paper for implementers of real systems.
