One important aspect of modern critical in … One important aspect of modern critical infrastructures
(CI) like power grids is that the control of the physical
processes (e.g., electricity transmission) is no longer done
locally but in a distributed way with SCADA/PCS systems.
This distributed control is done over utility networks, typically wide-area IP networks, that interconnect the CI facilities (e.g., transformation substations). This communication is critical because, if certain commands are not executed within certain time bounds, events with a severe socio-economic impact may happen (e.g., blackouts). However, utility networks often do not ensure the required timeliness and reliability, especially when accidental or malicious faults occur. This paper presents the Calm-Paranoid algorithm (CP), a novel overlay and multihoming routing strategy aimed to achieve adequate levels of timeliness and reliability in utility networks, even under harsh fault scenarios. etworks, even under harsh fault scenarios.
