“…SAND also defines control messages between DANE and clients, and between multiple DANEs. SDN technology can be utilized in SAND architecture [45]. DASH clients may directly select the quality recommended by an SDN controller [46], use bandwidth information sent by an SDN controller [47] or connect virtualized DANEs which were managed by an SDN controller [48], [27].…”

Adaptive streaming over HTTP is the dominant video streaming technology for more than a decade. HTTP Adaptive Streaming (HAS) systems provide a framework which enables clients to adapt quality with respect to network fluctuations during streaming, hence to optimize the perceived quality on the client side. Recently, network assistance is integrated with HAS in order to improve underlying network conditions and to provide network-related information to the clients. The performance of HAS systems can be further enhanced if the characteristics of the streamed video are considered. In this paper, we propose a HAS system architecture where Software Defined Networking (SDN) technology is utilized for assisting clients to select the most appropriate video codec and bitrate under the constraint of current network conditions as well as routing the video packet over the appropriate paths. In the proposed architecture, layered video is used, where each additional layer improves the quality. The controller estimates the packet loss probability by taking video codec characteristics, the bitrates of the layers and network capacity into account. Based on these estimations, the controller selects the appropriate codec type and video quality for the clients and manage the network. Simulation results show that the performance of the video streaming architecture can be improved significantly when codec, quality and path selection are jointly considered, and combined with SDN flexibility and advantageous.

“…This application also guarantees the integrity of the services, making possible to modify the service chains without altering the others, thanks to the identifier or ID, which allows recognizing the chain of services to be updated, by generating a display of a service chain request. A subset of switches in the WAN SD domain (software-defined red WAN), triggering dynamic adaptive capacity, redirecting traffic through other available switches [44].…”

Introduction: The review article is the product of the research on Security in SDN networks and their applications, developed at the District University in 2020, presenting the latest advances, that have been made in security. Problem: The security weaknesses that SDN networks have had, due to being a new architecture. This has not allowed traditional networks to be replaced. Objective: To carry out a review of the state of the art of SDN networks, focusing research on the security of the control layer and its advances. Methodology: The descriptive method is implemented, consulting databases such as Scopus, IEEE and ScienceDirect, using the following search criteria: SDN networks, security in SDN networks, applications with SDN networks and OpenFlow protocol. It is shown as a research sample: the Asian, European and American continents with years of research from 2014 to 2020. Results: Great advances have been made in terms of security for SDN networks, which allows us to see an early solution to the weaknesses that it currently faces. Conclusion: SDN networks will solve all the challenges they face and will be consolidated as a solid and reliable architecture. Originality: an important focus is taken on the security of SDN networks and the great development that has occurred in this regard is evident. Limitations: SDN networks are a new architecture, so their development has been very little and advances in security have been significantly affected.
