Abstract : This tutorial introduces the technologies of SOC (Service-Oriented Computing), SOA (Service-Oriented Architecture) and Service Management. Around the Web services, SOC is a rapidly evolving platform technology for the application development over the Internet. SOC comprises Web services, Peer (P2P) services, Grid services and Mobile services. SOC is becoming a mainstream of software platform for enterprises and networking. SOA is an emerging discipline for building decentralized applications on the SOC. SOA is addressing loosely coupling and standard interface modeling of business process integration. Service management is addressing two management models: management by Web services and management of Web services. A unified standard, WSDM (Web Services Distributed Management), is developed at OASIS. Participants can learn basic technologies and best practices of SOC/SOA. 1) Basic technologies of SOC include SOAP, WSDL, UDDI, WS-BPEL, and related techniques. 2) Core technologies of SOA include decentralized architectures and development methodology of BPM 3) On service management, we overview basic technologies for managing resourcesby Web services and 4) Illustrative examples highlight effectiveness of key technologies of SOC/SOA. Recommended Audiences are software/network engineers and researcher. LEVEL: INTRODUCTORY AND INTERMEDIATE |

Abstract : The optical fiber communications and networks are indispensable infrastructure for today's information world. The first part of the tutorial focuses on key elements; optical fibers, light sources, detectors, and optical amplifiers, and optical fiber systems/photonic networks. The second part focuses on using an IP-based control plane (GMPLS) to control the transport network. We will focus on the protocols that enable control including link management (LMP), routing (OSPF-TE) and signaling (RSVP-TE). We will describe the architecture and operation of a GMPLS-enabled network. The tutorial will explain how interoperability is achieved between many vendors in support of carrier requirements. It will also highlight challenges in operating GMPLS in deployed networks. Recommended audiences are network architects, system designers, engineers, technical managers and students who want to learn optical transport network and its control (GMPLS;Generalized Multi-Protocol Label Switching).

Tutorial 3: Inter-domain Traffic Engineering for QoS-guaranteed DiffServ Provisioning |

Abstract : In next generation Internet, an efficient traffic engineering function for QoS-guaranteed differentiated service provisioning is one of the most important required functions. DiffServ-over-MPLS traffic engineering has been standardized in IETF, and currently some Internet service provider is providing intra-AS (autonomous system) premium IP services, as simple differentiated service. This tutorial firstly explains the over protocol interactions for the QoS-guaranteed multimedia service request using SIP/SDP and RSVP-TE, the connection establishment and management in the provider network with COPS-CAC (common open policy service - connection admission control) and IP/MPLS transit networking. Especially, the virtual overlay networking for DiffServ-over-MPLS provisioning in each AS domain network is explained, and the QoS-provisioning schemes in broadband access networks, such as Ethernet PON (Passive Optical Network), IEEE 802.11e Wireless LAN and IEEE 802.16 Wireless MAN, are briefly explain. As the inter-AS traffic engineering across multiple IP/MPLS network providers, the MESCAL (Management of End-to-End Quality of Service Across the Internet at Large) architecture is explained. The distributed network operation and management based on Web service architecture is also explained as a practical implementation strategy. Recommended audiences are network architects, operations managers and staffs, and researchers in the area of high-speed telecommunications for data services. LEVEL: INTERMEDIATE |

Tutorial 4: OGSi (Open Services Gateway Initiative) Service Platform |

Abstract : The OSGi (Open Services Gateway Initiative) Alliance was established in 1999 to develop standards on the "OSGi Service Platform". In OSGi, functions of network appliances, including home gateways, cars, and cellular phones, consist of software components called "bundles", written mainly in Java. Since new bundles can be downloaded and activated via the network, operators/users can provide their appliances with new functionalities such as fixing bugs, and supporting diverse protocols, devices, user preferences, service logic, and so on. OSGi technology makes it easier to develop new services and applications for networked devices. The primary technical features of the OSGi service platform are lifecycle management ( install, start, stop, uninstall, update ) of bundles without rebooting the Java VM and OSGi service platform, and the use by bundles of functionalities called “services” provided by other bundles. Since the OSGi specification is open and doesn’t mandate policies for implementing OSGi technology, service providers will have flexibility in managing services in various business areas, including home automation, home security, ubiquitous application, cellular phone, energy saving, health care, telematics or education. This tutorial will provide • an overview of OSGi service platforms • use cases in business areas • OSGi technologies, including fundamental framework and services standardized in the specification. Recommended Audiences are researchers and engineers (system designers, middleware and application programmers) who are interested in middleware and in providing services using network-connected devices to users. Java experience is not mandatory. LEVEL: INTRODUCTORY |

Abstract : The present telecommunication environment is an amalgamation of a large number of networks, administrative domains, and different technologies. Multimedia applications, such as video conferencing and voice over IP (VoIP), require higher bandwidth, lower delays, and service continuity in addition to the demands placed by more traditional applications, such as email, web browsing, file transfer and instant messaging. Although there are several Quality of Service (QoS) frameworks, heterogeneous networks lack a widely-deployed mechanism that ensures end-to-end QoS. This tutorial contemplates the value of network overprovisioning and motivates the need for QoS for pragmatic applications. It introduces QoS mechanisms for local (802.11e) and wide (WCDMA 3G/UMTS) area wireless networks alongside more well-known Internet-based ones (Differentiated Services), surveys recent trends and discusses the path forward for QoS mechanisms. The tutorial emphasizes real-world examples, recent developments and research efforts by illustrating QoS measurement tools, QoS-aware gaming-on-demand applications, and seamless application and session continuity in heterogeneous networks. Finally, the research efforts in the EU EUREKA/ITEA Easy Wireless project are briefly described. Easy Wireless aims at allowing service continuity with managed quality of service and adaptive service provisioning for mobile users in heterogeneous network environments. Recommended audiences are scientists and engineers; telecom researchers and practitioners; network managers, service developers, and R&D staff; students.The level of the Basic background in networking is highly recommended.

Abstract : The ubiquitous sensor network (USN) is an infrastructure network for realizing the ubiquitous computing environment, generally consisting of huge number of tiny, low-power sensor nodes. The nodes of USN are vulnerable to failures, and have limited processing capabilities and usually communicate in wireless broadcast mode with auto-configuration capability. The application service of the USN is generally mission-oriented to specific applications such as military surveillance, disaster and environmental monitoring, and others. These characteristics of USN are different from the conventional data networks, and require a new paradigm on its management framework. In this tutorial, we introduce the basic characteristics of the USN, and issues and requirements of the USN management. We introduce the management architecture, management functional areas, and current research on the architecture and protocols. The management services specific to the USN such as power management, security management, topology management and context management are also introduced. The current standardization related to the USN is briefly addressed. Recommended audiences are management operators and engineers. LEVEL: BASIC AND MEDIUM |
