Design and implementation of seamless end-to-end Internet QoS management system

Seamless end-to-end Internet Quality of Service (QoS) management is very challenging not only because Internet management is not well understood and practiced in the real world but because the nature of the Internet is hard to predict and manage. Secure transmission, transport reliability, ability to differentiate service qualities, QoS-based intelligent routing, QoS monitoring, and customeroriented service management are essential technical huddles to be coped with. Despite of these difficulties, the Internet becomes the platform of choice for the next generation applications and services. Without a solid management solution, it is not easy to deploy high quality commercial services. In this paper, we propose an architecture of seamless end-to-end Internet QoS Management System and describe the design principles and system components of our developing prototype system.
