Abstract
In this research, the concept of piggybacking has been extended to concatenate
Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) packets. In any given
network scenario, voice (UDP) is given priority over data (TCP) packet. During high traffic load,
a UDP packet is processed at a higher priority, thus accumulating the TCP packets and leading to
congestion and retransmission of TCP packets. Because it is challenging to integrate UDP and
TCP packets an efficient queuing model has been proposed to concatenate the packets without
causing a negative impact on UDP or voice traffic. In this paper, we propose the algorithm and
model to concatenate UDP and TCP packets into a single packet and obtain better throughput for
TCP traffic, efficient utilization of network bandwidth. The concatenation is performed based on
parameters such as priority, destination and MTU size. The concept of discrete-time Markov
chain has been leveraged to analyze the router utilization and efficiently handle the concatenated
packets. The PCATTCP tool has been used to study the performances of UDP and TCP packets
traversing a LAN between two end hosts. These values have been used for the simulation of the
problem. Discrete Event Simulation has also been performed to determine the optimal values and
associated system parameters.
