Recently, researchers have started exploring the design of route protection schemes that
ensure networks can sustain traffic demand without congestion under failures. Existing
approaches focus on ensuring worst-case performance over simultaneous f-failure
scenarios is acceptable. Unfortunately, even a single bad scenario may render the schemes
unable to protect against any f-failure scenario. In this paper, we present Lancet, a system
designed to handle most failures when not all can be tackled. Lancet comprises three …
