BGP Multi-Homing Principles: Eliminating Single Points of Failure

What is Single Point of Failure (SPOF)?

In network systems engineering, Single Point of Failure is a single node or route which, if it fails, will completely paralyze the entire system. In large-scale telecommunications infrastructure, relying on a single upstream provider (upstream ISP) is a fatal risk.
