Today's implementations, in software or on FPGAs and ASICs that are attached to each host, are becoming increasingly complex, costly and bottlenecks to scalability. We present a different design that disaggregates network function processing off the host and into shared resource pools by making novel use of appliances which tightly integrate general-purpose ARM cores with high-speed stateful match processing ASICs. When work is skewed across VMs, such disaggregation can offer better reliability and performance over the state-of-art at a lower per-server cost. We describe our solutions to the consequent challenges and present results from a production deployment at a large public cloud.}, publisher = {USENIX}, url = {http://approjects.co.za/?big=en-us/research/publication/disaggregating-stateful-network-functions/}, }
