Software-Defined Networking and Security: Issues and Solutions

DISSERTATION ON:
Software-Defined Networking and
Security related issues associated
with it

Overview of the study
The internet and emergence of different technologies including
virtualization, Software-defined networking, Big Data, cloud, and
mobility have led to the creation of a digital society, where anything can be
accessible from anywhere at any time. However, along with several
advantages of technologies some limitations such as security, scalability,
and manageability etc. are also increased. It is very challenging task for IT
and network managers to o predefined policies and to reconfigure network
effectively. In the context of improving present business situations and
better respond to faults, load and changes related issues, SDN can be
beneficial for enterprises. Introducing the ability to program the network,
breaking vertical integration, and underlying routers and switches are the
major factors which are associated with the deployment of Software-
defined networking. The main purpose behind conducting present research
is to better explore the security related issues associated the implementation
of SDN. Furthermore, identifies the ways through which enterprises can
control and overcome Software-defined networking issues in a significant
manner.

Concept of Software Defined
Networking
Software-defined networking (SDN) is used to design, build and
manage network and better optimize them. It is a network architecture
which is used to support the dynamic movement and allocation of
virtual resources. Besides that, scale network functionality, reduce
complexity, and perform traffic engineering are the major
characteristics which are associated with the implementation of SDN
within enterprises. Software –defined networking is decoupled from
forwarding functions via dynamic, automated SDN programs. Network
manager is responsible for performing different tasks such as
configure, manage, secure, and optimize network resources etc. With
help of a graphical representation, Software-Defined Networking
architecture can be explored in a significant manner.
