Abstract
The method proposed in ITU-I.371.1 for the individualized-connection determination of the currently allowed transmission rate of ATM cells is inventively realized with the assistance of list parameters, whereby the list parameters indicate the plurality of current intermediately stored transmission rates and their size relationship relative to one another. As a result of this, a more efficient utilization of the computer resources of the ATM communication devices is achieved, as is a greater flexibility in view of the processing sequence of the individual method steps.
Claims18
A method for determining an individualized-connection currently allowed transmission rate of ATM cells of virtual connections having variable transmission rates, comprising the steps of:
- utilizing time change information allocated to transmission rate changes within an ATM communication system for determining said individualized-connection currently allowed transmission rate;
- intermediately storing a determined individualized-connection transmission rate of ATM cells, if it exists, in a memory unit;
- intermediately storing time change information relating to said transmission rate, if said time change information exists, in said memory unit;
- calculating said time change information using two individualized-connection prescribable delay times and utilizing a transmission rate handling routine;
- updating said time change information if it upwardly exceeds a predetermined time span by an updating routine, utilizing a current time value of a calendar information and an individualized-connection calendar information;
- utilizing a list parameter to indicate relative size relationships among a plurality of current said intermediately stored transmission rates;
- and
- determining said currently allowed transmission rate and updating said list parameter using said list parameter.
