N2 - Software Defined Networking and Network Function Virtualisation provide significantly more flexibility and control when provisioning QoS for delay sensitive services. Network delay can have a detrimental impact on VoIP quality and, therefore, minimising delay can help maintain the quality and prevent call dropping. This paper proposes a queuing scheme based on packet delay for prioritising VoIP calls made over SDN. An OpenFlow testbed was developed to validate our proposal, and results show that delay-based prioritisation of VoIP packets in SDN networks ensures that only a small number of users will be affected by network congestion.
