This paper presents an initial study on using diversity coding schemes for virtual network function (VNF) link and node failure recovery in 5G and beyond networks. In contrast to conventional link recovery methods, the proposed scheme offers near-instantaneous recovery times without retransmission requirements. Furthermore, the recovery scheme provides significant reduction in routing and capacity costs, at reduced number of redundant links and high number of traffic requests. Hence reliable recovery, node resiliency, reduced delays and ultra-low latency are achieved here. In addition, a mixed liner integer programming (MILP) optimization formulation model is also proposed for the VNF failure restoration.
