Transformation of a Token Bucket to a Work Conserving Link
Quality of Service (QoS) in IP multimedia converged networks which provides different serving levels of different traffic flows is a crucial issue. The token bucket mechanism is one of core QoS concept whose well understanding is required and improve modelling and implementation techniques required in such multimedia networks. This paper describes and defines two basic network elements - a work conserving link and a token bucket. The authors define two different types of a token bucket and they show that both of them can be transformed into some work conserving link. Transformation means that the work conserving link allows input unit to pass if and only if the token bucket would allow input unit to pass.
