Abstract
We design and evaluate a lightweight route verification mech-
anism that enables a router to discover route failures and
inconsistencies between advertised Internet routes and ac-
tual paths taken by the data packets. Our mechanism is
accurate, incrementally deployable, and secure against mali-
cious intermediary routers. By carefully avoiding any cryp-
tographic operations in the data path, our prototype im-
plementation achieves the overhead of less than 1% on a 1
Gbps link, demonstrating that our method is suitable even
for high-performance networks.
