Abstract:
Cloud Data Center Network (CDCN) is
receiving considerable attention and becomes one of
the hottest topics among academia and industry. It is
difficult to deliver the new emerging network services
in a flexible way and to fulfill the huge amount of
demand with better performance in a current data
center network. Traditional routing cannot provide
accessible performance for all traffic types, and it
can cause excessive link utilization in the network. In
this paper, we propose the resource allocation
scheme to support Quality of Service (QoS) for
various types of traffic while maintaining the network
link utilization as much as high. We present a
resource allocation scheme based on Software
Defined Networking (SDN) that integrates the
proposed scheme to provide better performance in
CDCN. We demonstrate the effectiveness of the
proposed scheme on the emulated SDN network. The
proposed scheme is compared with the conventional
shortest path scheme. Emulation results showed that
the proposed scheme provides better performance in
term of packet loss rate for the QoS traffics and great
improvement in link utilization.
