Abstract
Embodiments of the present invention provide for diverse routing of a plurality of data streams, representative of a client signal of an unknown format, across multiple communication paths of a digital optical network through the use of a marker embedded in the client signal which is then inserted into the client payload portion of a transport frame. The multiple communication paths include different signal and path attributes related to the optical signals which transport the data streams across the digital optical network, as well as the physical structure of the digital optical network itself, all leading to timing variations in the multiple communication paths. The digital optical network transports the plurality of data streams in the form of wavelength division multiplexed signals, or banded wavelength division multiplexed signals.
