Abstract
The growth in users streaming videos on the Internet has led to increased demand
for improved video quality and reception. In next generation networks (NGNs), such
as 3G and 4G LTE, quality of service (QoS) implementation is one of the ways in
which good video quality and good video reception can be achieved. QoS mainly
involves following an industry-wide set of standard metrics and mechanisms to
achieve high-quality network performance in respect of video streaming. Adopting
routing and communication protocols is one way QoS is implemented in NGNs.
This article describes QoS of bit rate video streaming, and QoS performance
analysis of video streaming, in relation to the main network transport protocols,
namely transmission control protocol (TCP) and user datagram protocol (UDP). A
simulation test bed was set up using OPNET modeller 14.5. In this setup, a network
topology was created and duplicated three times, in order to configure two simulation
scenarios (each using the distinct protocols), and a third simulation scenario using
both protocols in hybrid form. The findings in the simulations indicated that, when
a network is configured with both TCP and UDP protocols in video streaming,
there is a positive change in the degree of performance in terms of the QoS of videostreaming
applications, unlike when the protocols are used independently.
