G.8031 is a networking standard designed to provide survivability for Ethernet connections. It specifies protection switching for point-to-point VLAN-based Ethernet services. It is widely used in Carrier Ethernet networks to ensure that traffic can be rerouted within if a link or node fails. Core Mechanisms and Features Protection Architectures :

: Traffic is sent on both a "working" path and a "protection" path. The receiver simply chooses the best signal.

: Tutorials for software like Carbide Create Pro or Simplify3D demonstrate how to convert designs into toolpaths for routers.
