Abstract :
The paper derives lower bounds on the redundancy, the protection capacity to working capacity ratio, needed by link-protection or link-restoration. Homogeneity conditions, on which the well-known redundancy bound 1/(dmacr1) holds for a network, are also identified, where dmacr is the average nodal degree.
