Abstract

The protection aspects represent a fundamental point in designing a modern transport network. For this reason, SDH technology was developed taking into maximum account the survivability requirements. The evolution of backbone transport network towards the WDM technology will have also to take into account these aspects. In particular this paper highlights the open issues to coordinate the interworking between the SDH and WDM network layer, the trade-off between transparency and manageability, and presents a possible evolution scenario of how WDM technology could integrate into SDH-based transport networks. The increasing installation of WDM systems from point to point system to multi wavelength optical ring and even to optical cross connect will force the definition of new planning and protection strategies.
