T1. Lifecycle Management and Systems Engineering Techniques for Telecommunication Networks
Prof. Dr. Andy Snow, Ohio University, USA
The goal of this tutorial is to provide attendees a keen appreciation of the relationship between the network lifecycle, project management, and systems engineering techniques necessary to successfully design, develop, acquire, and field complex telecommunication networks.
What the telecommunication networking discipline has in common with the Information Technology field as a whole is that a significant number of projects fail because of poor definition at the beginning of the lifecycle of a system. As a consequence, this tutorial places heavy emphasis on network definition activities including network user requirements, system requirements, concept definition, component specification, and planning.
Emphasis will be placed on how to determine customer needs, translate those needs into network system attributes, develop an architecture capable of having the required network attributes, and specify and select components that will interact successfully to meet the necessary functional and performance attributes capable of satisfying user needs. A systems engineering perspective will also be included that provides for the decomposition of complex network systems into subsystems and major components. A taxonomy of network system attributes (system requirements) will be presented and the systems engineering techniques described to help ensure the chosen architecture and components exhibit these attributes.
T2. Overview of VoIP, and Multimedia over Broadband IP Networks
Prof. Dr. Nader F. Mir, San Jose State University, USA
In this tutorial, we present the fundamentals of VoIP and also Multimedia over IP network schemes. We explain signaling protocols and media exchange protocols for transportation of real-time voice over IP (VoIP) telephony and multimedia of IP networking. The tutorial reviews the control signaling protocols of H.323 series of protocols, and Session Initiation Protocol (SIP) which are responsible for session signaling. The tutorial further covers Compression of multimedia components such as Digital Voice and Video, focusing on data-compression techniques for voice and video to prepare digital voice and video for multimedia networking such as sampling, quantization, and encoding will be presented. The discussion also summarizes the limits of compression and explains typical processes of still-image and video-compression techniques, such as JPEG, MPEG, and MP3. The tutorial will then present real-time transport protocols, such as Real-Time Transport protocol (RTP) and the Real-Time Control Protocol (RTCP). The next topic is streaming video in a single server, using content distribution networks (CDNs). The tutorial describes detailed streaming source modeling and analysis. We also cover video streaming over from a video server to a client at the client request. The talk will cover type of-service (ToS) field in IPv4 packets and similar solution in IPv6. The Tutorial will then focus on the Stream Control Transmission Protocol (SCTP) providing a general-purpose transport protocol for message-oriented applications. SCTP services are placed at the same layer as TCP or UDP services. Streaming data is first encapsulated into packets, and each packet carries several correlated chunks of streaming details. The Tutorial will ultimately present multimedia over general Wireless and WiMAX networks.
