Abstract
Paths in a transport network are identified by labels (n-n, b-b) and more than one restoration resources that can be used for setting up a particular backup path form a restoration group. Backup tables (R, R) are provided, which define restoration groups per path labels (b-b), only, rather than individual restoration resources. Upon initial receipt of a path label (b-b), a network element (-) selects according to pre-determined rules a particular restoration resource from the restoration group defined in the backup table (R-R) for this backup path label.
