Abstract
A method for transmitting information data with a variable bit-rate (VBR) on a transmission channel with constant bit-rate (CBR) uses both a "lazy" algorithm and an "aggressive" algorithm. The "lazy algorithm" determines a transmission schedule where the smallest client buffer requirement and shortest working-ahead under a decided transmission rate may be obtained. The "aggressive algorithm" determines a transmission schedule whereby the highest utility rate of the network under a specific client buffer size may be obtained.
