Abstract
Being able to send different types of data (i.e. text, audio, or video) through the
network is the most important aspect of networks. Different networks have different issues
and restrictions while sending data. These restrictions are basically the QoS (Quality of
Service) metrics and security. The recent Software-Defined Networking (SDN) that aims
to separate the control plane from the data plane can be applied where Business
requirements are not responsible for the way the network is configured; instead, it is the
responsibility of the high-level business policies and objectives. SDN gives preferable
techniques for centralized dynamic management and control configurations. In this work,
a proposed model has been estimated and discussed to promote QoS requirements in some
suggested topologies. Adaptive Resource Management (ARM) and control to send different
types of data through different hosts have been investigated. The intended requirements
are basically the capacity and delay of traffic metrics sent through different hosts through
the network. It produces a mathematical model and implementation for three proposed
algorithms to enhance the quality of a sample video sent from source host to destination
host by Visible Light Communication (VLC)-media player in three different topologies.
These algorithms (statistical, MOGA, and PSO) have been implemented using Mininet
emulator, FNSS tool, PULP, and network libraries; with two types of controllers which
are Floodlight and OVS under Linux operating system and in python programming
language.
