Abstract The novel coronavirus disease-19 (COVID-19) infection has altered the society, economy, and entire healthcare system. Whilst this pandemic has presented the healthcare system with unprecedented challenges, it has rapidly promoted the adoption of telemedicine to deliver healthcare at a distance. Telemedicine is the use of Information and Communication Technology (ICT) for collecting, organizing, storing, retrieving, and exchanging medical information. But it is faced with the limitations of conventional IP-based protocols which makes it challenging to provide Quality of Service (QoS) for telemedicine due to issues arising from network congestion. Likewise, medical professionals adopting telemedicine are affected with low QoS during health consultations with outpatients due to increased internet usage. Therefore, this study proposes a SoftwareDefined Networking (SDN) based telemedicine architecture to provide QoS during telemedicine health consultations. This study utilizes secondary data from existing research works in the literature to provide a roadmap for the application of SDN to improve QoS in telemedicine during and after the COVID-19 pandemic. Findings from this study present a practical approach for applying SDN in telemedicine to provide appropriate bandwidth and facilitate real time transmission of medical data.

distancing being of extreme importance during this pandemic, much of healthcare has been move online or via telephone [2]. Due to the COVID-19 health crises several public health measures have been put in place such as temporal closing of public spaces and stay-at-home orders have been implemented across the world to support social distancing [3]. As access to diagnostic tools and healthcare is limited due to fewer availabilities of Personal Protective Equipment (PPE), Intensive Care Unit (ICU) beds, ventilators, etc.[4]. Efforts to de
