CENG 577 Advanced Services in Communications

Course Description

The main goal of the course is to unravel the new advanced services that will form the platform for the construction of scalable, reliable, and high performance new generation multimedia-rich mobile and wireless Internet-based applications.

The last several years have seen the phenomenal growth of the Internet and its emergence as the technology of choice for constructing major new services and applications, such as packetized audio and video (multimedia networking), mobile and wireless computing, and pervasive (ubiquitous) computing. In this seminar-style experimental course, we will examine the convergence of traditional voice-centric telecommunications networks and computer networks, and  applications-focused distributed middleware architectures, and the Internet.

The Internet as it is conceptualized today is mainly in terms of network and transport-layer protocols, with a weak model for services beyond connectivity. Traditional telecommunications networks include well-developed service models, but these are strongly tied to telephony. Elements include control via Signal System 7, the distribution of application processing in the Advanced Intelligent Network, the new frameworks for Internet-based core architectures for Third Generation Mobile Networks, and proposals to generalize the existing telephony architecture such as the object-based TINA architecture. Middleware-oriented distributed applications architectures include SOA, RMI, EJB, JINI and CORBA.

Through the readings of technical and survey papers, student presentations, seminar-style discussion, and applied research projects, we will learn the proposed services and architectures. Students will pursue a substantial research project as part of their course grade.
