Delay-Aware Resource Sharing

摘要

The invention relates to a method for controlling a transmission buffer in a transmission node of a transmission network transmitting data packets of a data packet flow, wherein each data packet includes a delay value indicating a transmission delay requirement of the data packet and a packet value indicating a level of importance of the data packet. The buffer includes different buffer regions and an arriving data packet is put into its respective buffer region based on the delay requirement indicated by a delay value contained in the data packet. The number of bytes waiting before the freshly arrived data packet cannot increase so that the delay requirement is met and possibly other packets in the buffer might be dropped for the newly arriving packet.
