Patent ID: 7457243

Claim:
A method for processing a data packet stream in a communications system, with the steps of: receiving a first admission control packet that includes a number of admission control parameters, reading from said first admission control packet at least one admission control parameter indicating a throughput required for a real-time processing of a sub-stream of data packets related to the first admission control packet, wherein the step of reading comprises reading a maximum throughput, determining a currently available throughput, comparing the available throughput with the required throughput, admitting the real-time processing of the sub-stream, if the available throughput is higher than or equal to the required throughput; and choosing for the sub-stream a throughput between the required throughput and a minimum of the maximum throughput and the available throughput; sending the sub-stream if it is admitted for real-time processing to a packet scheduler for real-time processing; determining a delivery deadline for a payload data packet of the sub-stream admitted for real-time processing; sorting the payload data packet into a first queue; and setting a time stamp, that is related to the sorted payload data packet, in the first queue to the determined delivery deadline.
