The focus of research into 5G networks to date has been largely on the required advances in network architectures, technologies, and infrastructures. Less effort has been put on the applications and services that will make use of and exploit the flexibility of 5G networks built upon the concept of software-defined networking (SDN) and network function virtualization (NFV). Media-based applications are amongst the most demanding services, requiring large bandwidths for high Manuscript
Media applications are amongst the most demanding services requiring high amounts of network capacity as well as extremely low latency for synchronous audio-visual streaming in production quality. Recent technological advances in the 5G domain hold the promise to unlock the potential of the media industry by offering high quality media services through dynamic efficient resource allocation. Actual implementations are now required to validate whether advanced media applications can be realised benefiting from ultra-low latency, very-high bandwidth and flexible dynamic configuration offered by these new 5G networks. A truly integrated approach is needed that focuses on the media applications not only on the management of generic network functions and the orchestration of resources at the various radio, fronthaul/backhaul, edge and core network segments. The H2020 5G PPP Phase 2 project 5GMEDIA [1] leverages new options for more flexible, ad-hoc and cost-effective production workflows by replacing dedicated lines and hardware equipment with software functions (VNFs) facilitating (semi-) automated smart production in remote locations. Highly scalable virtualized media services deployed on or close to the edge reduce complexity for the user, ensure operational reliability and increase the Quality of Experience (QoE). Virtual compression engines have the potential to replace dedicated encoder/decoder hardware while the network optimisation (Cognitive Network Optimizer) in combination with the Quality of Service (QoS) monitoring helps to overcome the current internet best-effort principle and ensures that the required performance needs are met at all times.
Abstract-The 5G advent is stimulating research and development of new solutions and tools to serve the Media & Entertainment industry in oder to cope with all the demanding requirements for very high volume (downlink and uplink), for service fruition across multiple devices, for anytime and anywhere coverage, for Quality of Service and security.In this paper, we focus on scenarios and requirements to implement orchestrated virtual CDNs in 5G networks used to distribute ultra-high-definition media contents. This work originates from the research activities within the H2020 5G-MEDIA project, in which We are designing a solution across the edge Point of Presence (PoP) and core data-centers of an operator network, to allow the distribution of UHD media contents from central production centers to end users. Our vCDN solution can elastically cross various anchor points for fixed and/or mobile broadband services down till personal devices, both fixed and mobile to properly serve users attached to the 5G network. The work reports on results of our initial design phases and focuses on the specific scenarios and requirements in our scope. The implementation of the designed virtual CDN solution powered by the 5G-MEDIA management and orchestration platform is an ongoing task, which -once completed -will allow us to validate the proposed scenarios and service orchestration approaches through the 5G-MEDIA in the project testbeds.
