A Survey on Autonomic Provisioning and Management of QoS in SDN Networks
In today's Internet, killer network services and applications, such as video and audio streaming, network storage, and online video games, are pushing the network infrastructure resources to the edge. By design and for the most part, the Internet is the best offer delivery ecosystem with little or no end to end quality of service (QoS) guarantees. Even, frameworks, such as IntServ and DiffServ that were designed and implemented to provide QoS guarantees, still fail to solve this problem at a wide scale. Software defined networking (SDN) is a fast emerging networking paradigm that promises to provide end to end QoS guaranteeing by offering greater network flexibility, abstraction, control, and programmability to network resources. In this paper, we review, survey, and discuss the current state of the art on QoS provisioning in the area of SDN, with respect to applying the concept of autonomic computing (AC) to automatically support, provision, monitor, and maintain QoS requirements. This paper includes in depth classification, taxonomy, and comparative analysis for the autonomic based QoS provisioning in accordance with the famous influential and widely adopted the monitor analyze plan execute knowledge (MAPE K) IBM architectural model for autonomic computing.
