The CNF architecture can be implemented as an overlay on top of the Internet Protocol (IP), or as a clean slate protocol for next-generation networks. CNF is based on the concept of store-and-forward routers with large storage, providing for opportunistic delivery to occasionally disconnected mobile users and for in-network caching of content. The proposed CNF protocol uses reliable hop-by-hop transfer of large data files between CNF routers in place of an end-to-end transport protocol like TCP. This approach makes it possible to serve mobile users with intermittent connectivity, while also mitigating self- interference problems which arise in multi-hop wireless scenarios. Hop-by-hop transport is similarly useful in wired networks where router storage can help to smooth out link congestion bottlenecks which arise in TCP/IP networks. A second key feature of the CNF protocol is the integration of address- based and content-based routing to support various content delivery modes that take advantage of in-network storage. An overview of the CNF architecture and major protocol components is given, and preliminary performance evaluation results are summarized to validate the main design principles.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131860970","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}

User-centric service architecture will offer services to the actual user, and not to the specific line or device. The future of such user-centric services to be offered by telecom operators depends on the efficient and realistic deployment of fully FMC convergent architecture as evolution of the current infrastructure. Operator needs to face significant adaptation and integration challenges described by the standards that will make the difference in order to get to the market with the appropriate strategic position and technological solution. Accordingly, services for Enterprises will be the first step towards the convergent scenario. However, corporations have performed significant investments on CPEs, on infrastructure and service logic, and operators shall propose a seamless way to evolve to a convergent picture without jeopardizing the customer's investment. The proposed architecture uses standard protocols to integrate CPE service logic into horizontal network service layer, taking advantage of the CPE investment that the corporations are not willing to replace. Specific implementation details, signaling flows and pros/cons analysis for such architectural decisions are provided.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"31 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134522374","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}

Advanced modulation schemes for optical signals, such as differential quadrature phase-shift keying (DQPSK) and orthogonal frequency-division multiplexing (OFDM), are promising for such large-capacity networking. In this paper, highspeed optical modulators with a hybrid configuration of silica-based planar lightwave circuits and LiNbO3 phase shifters are presented. Combining the advantages of the two components, the hybrid modulators offer high-speed responses as well as complex configurations and low optical losses. Using this technique, a DQPSK modulator, a return-to-zero- (RZ-) DQPSK modulator, and a two- subcarrier-OFDM-DQPSK modulator have been fabricated. Demonstrations of 10-Tb/s-class wavelength-division-multiplexing (WDM) transmission with 100-Gb/s- class data rate per channel using them are successfully achieved.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127665739","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}

The NGN promotes separation of service implementations from network infrastructure by using service enablers. Service enablers are reusable abstractions that provide access to network capabilities. Enablers are used by applications to create services for customers and offer external enterprises access to NGN capabilities. No appropriate NGN service platform architecture is standardised to date. This paper shows how services and service enablers are defined and structured within a standards-based NGN service platform architecture. We motivate the Service Delivery Platform (SDP) framework for standardising the NGN service platform architecture. The SDP framework defines an extendable, technology-neutral service platform architecture. The framework consists of building blocks structured according to Generic Service Oriented Architectures (GSOAs) presented here. The GSOAs are implementable using standards-based technologies. After providing background on the NGN. we elaborate on the SDP and GSOA. We present our SDP framework using multiple GSOAs. In addition, we discuss and evaluate a SDP implementation.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128457387","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}

Ideally one would like to specify and analyse services on a high level of abstraction, using modelling concepts close to the user and problem domain rather than at the platform and implementation domain, and then be able to derive design components and implementations from service models with a high degree of automation. It is argued in this paper that this conception is approaching reality and so is worth while pursuing to face the challenges of service engineering in a NGN context. The basis for this is new approaches to model services precisely, to analyse goals and tradeoffs concerning variability and context, and to transform service models into platform independent models from which implementations are automatically generated. Interestingly, the service models can provide information and mechanisms that help dynamic composition and adaptation at runtime. The approach is illustrated using a multimedia call service with access control requirements.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128758756","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}
