Abstract
Traffic within a data center can sometime lead to congestion due to imbalance of distribution of traffic. In this paper, a software-defined networking (SDN) approach to traffic engineering within a data center is described. A video traffic distribution scheme is designed based on SDN, to improve network availability by means of multipath thus achieving load balancing. In this paper, queue bandwidth allocation (QBA) algorithm is proposed which allocates bandwidth to video traffic and other classes of traffic. QBA uses the concept of queue in OpenFlow (OF) 1.3 ([1] and McKeown et al. in ACM SIGCOMM Comput Commun Rev [2]) which guarantees quality of service (QoS) by reserving bandwidth on each queue for each class of traffic based on the priority of each class of traffic which is discussed in Sect. 3. Finally, simulations are performed to show that our proposal is significant in achieving load balancing to solve the queue congestion problem as well as allocate bandwidth to each queue using QBA.
