An optical signaling header technique applicable to optical networks
wherein packet routing information is embedded in the same channel or
wavelength as the data payload so that both the header and data payload
propagate through network elements with the same path and the associated
delays. The technique effects survivability and security of the optical
networks by encompassing conventional electronic security with an optical
security layer by generating replicated versions of the input data
payload at the input node, and the transmission of each of the replicated
versions over a corresponding one of the plurality of links. Moreover,
each of the links is composed of multiple wavelengths to propagate
optical signals or optical packets, and each of the replicated versions
of the data payload may be propagated over a selected one of the
wavelengths in each corresponding one of the plurality of links.
