DiffServ Are there any successful implementations of QoS
Topic: DiffServ – Are there any successful implementations of QoS. ... In this new world order, the most critical roadblock to successful network integration is quality of service (QoS). QoS (Quality of Service) is the capability to provide different levels of service to differently characterized traffic or traffic flows. There have been many attempts to provide some kind of QoS with the current Internet IP network; IntServ, DiffServ and MPLS are a few of them. Unfortunately today’s internet network does not support any QoS model. Although there are many designs available to guarantee QoS the problem is to make this new design work with minimal change to the current architecture of internet network. Differentiated Services The Differentiated Services (DiffServ) standard was designed to help solve the IP quality of service problem. The DiffServ approach to providing QoS in networks uses a small, well-defined set of building blocks from which a variety of services can be build. ... DiffServ works only at the edges of the network.
