Productivity is one of the top reasons, why Enterprises implement remote access methods to access their corporate networks. While there are several remote access methods defined today for accessing corporate networks, however there are several enhancements to consider to make next generation remote access implementation to run smoothly in existing corporate networks. In this paper, we review and identify shortcomings of existing remote access methods. We propose 2 solutions based on Mobile IP to overcome shortcomings of the existing methods and address the coexistence of our proposed techniques with existing ones. Compared with an existing VPN access method with PPP, our proposed solution offer the following advantages in terms of better usability as well as a stronger prevention of information leakage, by unifying the two authentications (one for the Layer 2 access to the carrier and the other for Layer 3 access to the enterprise network) into one at the enterprise network.

This paper presents a novel "cache-and-forward" (CNF) protocol architecture for mobile content delivery services in the future Internet. 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.

In this paper architectural network evolution based on specific PBX-gateways is presented, in order to make it possible to efficiently integrate the PBX extensions in an IMS-based service layer. 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.

Future optical transport networks should offer 10-Tb/s- class total capacity, and must be able to transport 100- Gb/s-class client signal transparently as well. 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.

Quantum key distribution (QKD) has been studied as an ultimate method for secure communications, and it now is emerging as a technology that can be deployed in real fibre networks. Here, we present our QKD experiments based on the differential phase shift QKD (DPS-QKD) protocol. A DPS-QKD system has a simple configuration that is easy to implement with conventional optical communication components, and it is suitable for a high clock rate system. Moreover, although the DPS-QKD system is implemented with an attenuated laser source, it is inherently secure against strong eavesdropping attacks called photon number splitting attacks, which pose a serious threat to conventional QKD systems with attenuated laser sources. We also describe three types of single photon detectors that are suitable for high-speed, long-distance QKD: an up- conversion detector, a superconducting single photon detector, and a sinusoidally gated InGaAs avalanche photodiode. We present our record setting QKD experiments that employed those detectors.

It's undeniable that peer-to-peer applications have posed increasing threat to the telecom operators since the end of 1990s. The threat is two-fold. One is that the P2P applications generate tremendous amount of traffic to the telecom network, resulting in network management problems and increasing both capital and operating expenditures; the other is the revenue loss caused by some P2P applications such as free or nearly free Internet voice services offered by P2P operators. Most of the operators have either taken drastic measures, such as discriminating P2P applications by blocking or delaying P2P traffics, or totally ignoring the problem. In this paper we propose an alternative solution. This solution, taking the advantages of both telecom network and P2P network architectures, can enable the operators to capture the revenues from P2P applications without loosing the current telecom revenues. It provides carrier grade P2P services in an IP based network with minimum impact to the current network architecture and services. We argue the benefit of this approach from its technical and business aspects.

IP-based TV services bring opportunities for interactivity and personalization. They also bring challenges in delivery quality and interoperability. Open standards are essential to ensure market success but also to enable innovation of future services and applications. We give an overview of the current status of IPTV standardization, especially how specifications complement each other to achieve a complete system. Some key challenges and opportunities are described, including how to enable 3rd party innovation on top of IPTV platforms.

The Next Generation Network (NGN) represents a telecommunications network that provides a variety of services to customers across converged telco, enterprise and Internet infrastructures. 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.

Service engineering is the process of service development from domain analysis and requirements capture, through specification, design and implementation, to deployment and adaptation on service delivery platforms. 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.
