In OcNOS, this feature enhances the routing experience by forming a detour in a ring topology. When a failure or congestion occurs in the primary Label Switched Path (LSP), the detour protects data traffic. The detour formation is a local protection mechanism to minimize data traffic loss.

For more information, see the RSVP Detour Over Ring Topology section in the OcNOS Key Feature document, Release 6.4.1.
