دانلود SDN, A Research on SDN Assets and Tools to Defense DDoS Attack in Cloud Computing Environment

Abstract

Software  Defined  Networking  has  become  a  drone word  to  service  and  cloud  providers  since  when  they  feel  the need to make the network programmable. As the devices in datacenter and applications continue to rise in number, the need for bandwidth,  storage  and  computing  power  grows  substantially. This  infrastructure  needs  to  be  managed,  maintained,  updated, powered and cooled. As a result, the traditional data center model is  becoming  too  costly  and  complex  to  sustain.  Also,  security threats  are  growing  significantly,  Distributed  Denial  Service  of Attacks  (DDoS)  is  one  of  those  vital  security  threats.  With  the advancement  of  Software  Defined  Networking  (SDN),  defense mechanisms against DDoS attack has opened a new door to cloud computing environment. Based over SDN, new infrastructure of cloud computing has brought novel possibilities to defense against DDoS attacks. In this paper, we are going to discuss on some of the  valuable  features  of  SDN  and  show  we  can  make  full  use of SDN’s assets and advantages to make cloud highly competent and secured against all threats. The research results in this paper can be expanded to prepare a new architecture of SDN enabled secured IoT  based  cloud environment.
