Abstract:
A system and method is disclosed that assures component circuits transported in aggregated circuits restore correctly after an aggregated circuit fault. The system and method implements component circuit tail segment integrity checks whenever an aggregated circuit is restored in a higher level of a network hierarchy. Switches at both ends of an aggregated circuit perform circuit integrity checks of the tail segments of every component circuit. A failure of the component circuit integrity check on any component circuit causes that component circuit to be released and restored end-to-end.
