Abstract
A method and apparatus for enabling restoration of connections upon failure within a high-speed data transfer architecture, such as SONET/SDH channel, is provided. The design detects health codes generated by detecting elements, the health codes representing the health of each channel. The design processes these health codes to determine re-provisioning of the failing connection where appropriate. This restoration decision-making apparatus communicates the resultant re-provisioning scheme to repairing elements. The design may detect and communicate health codes relating the health of each channel to determine which code reports a healthier channel among a plurality of transport channels available for carrying re-provisioned traffic due to a failed connection.
