Ultra-reliable NFV-based 5G networks using diversity and network coding

Abstract

This paper presents a robust solution for link and node failures in network function virtualization for 5G and beyond system. Namely, the synergistic combination of Diversity and Network Coding schemes is leveraged here for robust link failure recovery. The scheme offers near-instantaneous packet recovery without feedback requests with enhanced throughput. Hence, it eliminates latency associated with retransmissions and rerouting by using error control across spatially diverse paths.
