Accurate Network Resource Allocation in SDN according to Traffic Demand
Hongyan Cui, Chenhang Ma, Wei Lai, Lili Zheng, Yunjie Liu · 2015
The services carried by the Internet have undergone tremendous change over the past decades, along with the emergence of multimedia services and cloud computing, etc.However, there is little change in the framework of network designed primarily for reliable end-to-end communication, which is not suitable for these new services, resulting in poor performance of services and inefficient utilization of network resource.In this paper, we propose a network resource allocation scheme base on SDN (Software Defined Network) an emerging network paradigm, to provide Quality of Service (QoS) support for various services while balance the link load in the network avoiding congestion and idleness.And we demonstrate its performance via experiments under our SDN test bed.
