Backup tables (R1, R7) are provided, which define restoration groups per path labels (b1-b4), only, rather than individual restoration resources. Upon initial receipt of a path label (b1-b4), a network element (1-13) selects according to pre-determined rules a particular restoration resource from the restoration group defined in the backup table (R1-R7) for this backup path label. | |
