Numerical analysis of packet merge technique: The QoS improvement and the application domain

The packet merge technique combines packets and lowers the packet rate to improve the Quality of Service (QoS) degradation of a network caused by the increase in the delay time and packet losses due to a longer router queue and buffer overflow caused by the high packet rate traffic. However, combining the packets is accompanied by an increase in the waiting delays due to waiting for succeeding packets and transmission delay due to the larger packet size. Therefore, this situation becomes a new source of QoS degradation. There is a trade-off relationship between the improvement by this technique and the delays generated by the technique. Suitable applications and parameter settings are important to improve the QoS. In this paper, we derive the delay time distribution and the packet loss rate of the received packets passing through a network applying this packet merge technique, and describe the characteristics of this technique and the application domain. © 2006 Wiley Periodicals, Inc.
