Q85 / 100
What is PCE (Path Computation Element) in MPLS/SR networks?
Correct! Well done.
Incorrect.
The correct answer is B) A centralized or distributed component that computes traffic-engineered paths in MPLS-TE and Segment Routing networks using full topology knowledge
B
Correct Answer
A centralized or distributed component that computes traffic-engineered paths in MPLS-TE and Segment Routing networks using full topology knowledge
Explanation
PCE (RFC 5440, PCEP protocol) computes optimal TE paths considering bandwidth constraints, affinities, and SLAs. In SR-PCE (Segment Routing), the controller installs explicit segment lists on ingress routers.
