In this work, we extend the concept of architectural vulnerability factor (AVF) from the microprocessor domain and propose a network vulnerability factor (NVF) to characterize the susceptibility of Network Interfaces (NIs) to soft errors. For the first time, a detailed characterization of vulnerability is performed on a state-of-the-art AXI-based NI architecture using full system simulation. Our studies reveal that different NI buffers behave quite differently in the presence of transient faults and each buffer can have different inherent tolerance to faults. Our analysis also considers the impact of thermal hotspot mitigation techniques on the NVF estimation.
