Course Description

This course covers issues in building QoS (Quality of Service) sensitive networked services on top of the wired and wireless Internet infrastructure. Examples of such networked services include media streaming, personal messaging, group communication, and E-commerce. These services are value-added and application-level services based on the network infrastructure. We will study the impact of network infrastructure on the design, implementation, and performance of networked services, as well as system support for the provision of QoS in these services. Detailed topics include:

Overview of Internet QoS provisioning techniques: QoS routing, integrated service (Intserv), bandwidth reservation, service disciplines, differentiated service (Diffserv), rate control;
Service discovery, server and proxy selection;
Overlay networks and application in content distribution;
Web caching and data replication;
Service adaptation (both server-side and client-side) in dynamic and heterogeneous environments;
Service management middleware;
Overview of wireless networking techniques: MAC layer scheduling, Mobile-IP, wireless transport protocol, routing in ad hoc networks;
Mobile data access and processing;
Location and context-aware mobile services;
User-level mobility support.

Grading Policy

Each student is expected to (1) present two papers from the reading list, (2) write a two-paragraph critique on the paper to be presented (whether one is the presenter or not) before each class, (3) participate in discussion during and after each presentation, and (4) do a course project related to the general topic of this course but not limited to the specific topics covered by the papers presented. Final grade breakdown: 30% on paper critiques, 30% on presentation and class participation, and 40% on course project.
