5G communication networks enable the steering and control of Internet of Things and therefore require extreme low latency communication referred to as the tactile Internet. In this paper we show that the massive use of network coding throughout the network significantly improves latency and reduce the frequency of packet re-transmission, so an architecture built around network coding may be a feasible road towards realizing the tactile internet vision. Our contribution is threefold: (i) we show how network coding improves latency and reduces packet re-transmission with respect to other coding schemes in an analytical manner, (ii) we present our implementation of a network coding capable software router and support our analytical results with realistic measurements, and $(iii)$ we show that, to the contrary to current packet-switched networks, network coding scan be seamlessly integrated to Software Defined Networks (SDN) using our software router as a Virtual Network Function. Such combination of network coding and SDN summons a code-centric networking architecture that can be a promising host of future 5G.
