Abstract

Future networks are expected to support heterogeneous traffic, including both Internet Protocol (IP) and wavelength services. IP services are typically restored using IP-layer rerouting mechanisms, whereas wavelength services are restored in the optical layer. With architectures where IP services are mapped into Layer-2 or time-division-multiplexing (TDM) protocols at the network edge, a common restoration mechanism can be utilized for both IP and wavelength services. This letter examines various nodal architectures that can be utilized to support such a unified restoration paradigm.
