At the same time, the increasing popularity of the voice-over-IP (VoIP) services requires call authorization solutions that allow to charge only one of the users involved in a multimedia session for the payment of all the resources used for it. In this paper, we propose a consortium-based trust model between providers of network resources and providers of voice-over-IP services that allows them to share information for the authentication and the authorization of their users. We define a new model for authentication and authorization of roaming users and a signaling solution for it based on the Extensible Authentication Protocol (EAP) and the Network Access Control Protocol (NACP). We also define a new authorization model for multi-domain VoIP calls and we propose a signaling solution for it based on the Next Steps in Signaling protocol (NSIS).","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131557617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graph's robustness is quantified with the node and the link connectivity, two topological metrics that give the number of nodes and links that have to be removed in order to disconnect a graph. The algebraic connectivity, i.e. the second smallest eigenvalue of the Laplacian matrix, is a spectral property of a graph, which is an important parameter in the analysis of various robustness-related problems. In this paper we study the relationship between the proposed metrics in three well-known complex network models: the random graph of Erdos-Renyi, the small-world graph of Watts-Strogatz and the scale-free graph of Barabasi-Albert. From (Fielder, 1973) it is known that the algebraic connectivity is a lower bound on both the node and the link connectivity. Through extensive simulations with the three complex network models, we show that the algebraic connectivity is not trivially connected to graph's robustness to node and link failures. Furthermore, we show that the tightness of this lower bound is very dependent on the considered complex network model.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"395 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116500905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider a general class of prediction agents which forecast the number of future incoming handovers. For the optimization process we propose a novel Reinforcement Learning approach based on the concept of after states. The main objectives of the paper are twofold. First to quantify the impact that different ways of aggregating the movement prediction information referred to different service classes have on system performance. Second, to evaluate the sensitivity of the optimal anticipation time with which the admission controller needs to know the predictive information with different system parameters. Numerical results show that with the proposed aggregation of the predictive information we obtain policies as good as those obtained with the conventional representation of the system state, but at a lower computational cost. Besides, although the performance gain varies with system parameters, the location of its maximum remains almost invariant with the anticipation time in all the studied scenarios.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126436162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the decade where the Internet Protocol becomes mainstream in communication networks integrating and carrying all new types of services with increasing traffic volume and complexity, there are rising concerns whether the aging Internet protocol architecture with its underlying legacy routing algorithms, control and security mechanisms would soon collapse under the load of new applications and the rapid change of traffic patterns and service generation paradigms in the next decade. In the talk we will focus on trends and evolution paths towards the Next Generation Network. The talk will discuss these trends together with issues of system performance and stochastic scalability, which are current topics of intensive research. These issues are crucial to dimension networks and applications, both from network provider and equipment manufacturer viewpoints. Some observations on future services will commence the talk. It will discuss the notion of Multi-Network Services, i.e. the paradigm shift from a network-centric view to a applicationcentric view. In the current existence of several wireless and wireline networks (PSTN, UMTS, WiMAX, etc.) users of different networks can install service-enabling software and start a new type of service in a short time scale and in a very dynamic way (e.g. VoIP platforms like Skype, software distribution schemes like Bittorrent, etc.). Those services are multi-networks services, which correspond to the term of Edge-based Intelligence.","PeriodicalId":207883,"journal":{"name":"2007 Next Generation Internet Networks","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125348548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
