This paper analyzes critical parameters that must be provided by an optical link based on MPLS-TP to satisfy the demand of protection schemes. Impedance protection is sensitive to latency while differential require symmetry that must be assured.

The use of Ethernet, MPLS, and IEC-61850 in power grid networks enables the deployment of robust and scalable infrastructures, as well as the use of standard protocols that facilitate interoperability, control, and service efficiency.

MPLS is considered a reliable and efficient technology for supporting mission-critical applications as it provides a mechanism for efficient packet forwarding,allowing for the creation of virtual private networks (VPN)
