N2 - The increasing demand for low-latency, high-bandwidth connectivity has introduced novel challenges to de-livering strong resilience guarantees in production network envi-ronments. Closed hardware platforms, known as middleboxes,that lack visibility and support for state retention remain akey challenge for continuous service delivery during networkfailures. These middleboxes rarely employ recovery mechanismsof their own, inspiring renewed interest in the field of NFV inrecent years due to this gap within the industry. The increasingavailability of VNF capabilities in modern infrastructures offersan opportunity to exploit the flexibility of software and usehybrid architectures to improve resilience. Katoptron is a high-availability service that propagates state between unmodifiedhardware middleboxes and backup PNF or VNF appliances.The platform utilises targeted packet mirroring to allow networkdevices to organically construct equivalent state and thus allow aneasy transition between hardware and software. To demonstrateits viability, we have evaluated Katoptron against a wide range ofcommon hardware middlebox use cases built using multiple open-source packet processing frameworks. Results show upwards of90% matching state with no observable delay to normal trafficor impact on its functionality.
