Emerging applications expect fast turn-around from in-network failover mechanisms. This paper starts exploring the design space for supporting high availability and low latency using fast reroute in programmable data planes. In particular, we present a primitive for supporting well-known fast reroute mechanisms that is both efficient in terms of packet processing latency, memory requirements, and switch throughput.
