Internet Interconnection Techno-economics: A Proposal for Assured Quality Services and Business Models

The Internet is constructed by means of complex business interconnection agreements among multiple networks. However, the most commonly used agreements do not contain explicit Quality of Service reference. In this study a business rationale for Assured Service Quality (ASQ) inter-network services is presented and potential business models for their realization are proposed and analyzed. It is argued that ASQ products and business models could greatly enhance the health of the Internet interconnection ecosystem. A business model design framework that encompasses the key strategic decisions that would enable ASQ provisioning and generic collaboration is also provided. This framework is then elaborated using a number of off-net content delivery scenarios. Conclusions are hence drawn on the role of ASQ and ASQ-driven business models for the sustainable development of the "Future Internet"

The Cost 249 Speechdat Multilingual Reference Recogniser

The COST 249 SpeechDat reference recogniser is a fully automatic, language-independent training procedure for building a phonetic recogniser. It relies on the HTK toolkit and a SpeechDat(II) compatible database. The recogniser is designed to serve as a reference system in multilingual recognition research. This paper documents version 0.93 of the reference recogniser and presents results on smallvocabulary recognition for seven languages

The COST 249 SpeechDat multilingual reference recogniser

The COST 249 SpeechDat reference recogniser is a fully automatic, language-independent training procedure for building a phonetic recogniser. It relies on the HTK toolkit and a SpeechDat(II) compatible database. The recogniser is designed to serve as a reference system in multilingual recognition research. This paper documents version 0.95 of the reference recogniser and presents results on small and medium vocabulary recognition for five languages. The paper is a sligthly expanded version of a paper presented at LREC-2000 (Johansen et al., 2000). 1

A noise robust multilingual reference recogniser based on SpeechDat(II

An important aspect of noise robustness of automatic speech recognisers (ASR) is the proper handling of non-speech acoustic events. The present paper describes further improvements of an already existing reference recogniser towards achieving such kind of robustness. The reference recogniser applied is the COST 249 SpeechDat reference recogniser, which is a fully automatic, language-independent training procedure for building a phonetic recognise

Inter-domain Coordination Models

Part 2: Economics and Technologies for Inter-Carrier ServicesInternational audienceIn order for the Network Service Providers (NSPs) to provide end-to-end Quality of Service (QoS) at the inter-domain level different coordination models have been proposed by ETICS project. In this work we present and analyse the plausible alternatives of those models and we compare them with each other in terms of information asymmetry issues. We show that different information sets affect the total service provision and we present a basic model analysis on information issues by means of game-theoretic models
