Abstract
Nowadays, there is huge increase on mobile traffic that cannot be managed in 5G requirements with the existing physical infrastructure. To handle these requirements, we consider the new mobile access protocols in 5G. They vary according to Android and iOS operating systems, and these devices use UDP-based QUIC and TCP-based HTTP/2 protocols for video access, respectively. Therefore, there is a need for dynamic routing of video traffic according to the mobile user in low OPEX/CAPEX. To handle this challenge, we use the Software- Defined Networks. However, conventional routers can open the header of the incoming packet up to transport layer and can only forward according to carrying over either TCP or UDP protocol. Even the standard OpenFlow protocol using communication between dummy switches and controller on SDN, does not support routing by application layer (Layer 5). Therefore; in this paper, a mobile access aware routing is proposed. In ONOSbased SDN control, the newly defined forwarding rate (Rate) is calculated periodically. A new algorithm has been proposed that dynamically directs iOS/Android based video traffic according to the threshold value of this ratio. The standard Reactive Forwarding algorithm in the ONOS does not consider the intensity and mobile traffic rate. As a result, these challenges have been overcome with proposed algorithm, and the QoS values of the video traffic have been met the 5G requirements. © 2021 IEEE.
