Abstract
There are several schemes to ensure the reliability of WDM networks, such as hardware redundancy and network redundancy. The problem of choosing a rational option for network redundancy for WDM networks is no less relevant than for SDH networks. The WDM network, like the SDH network, can be represented as a set of typical structures: linear (single-connected structure), ring (two-connected) and cellular (multi-connected). For redundancy of optical networks based on cellular topology, a redundancy mechanism based on p-cycles is proposed. Currently, the concept of p-cycles is increasingly being used on European transport communication networks.
