Title: Impairments And Other Constraints On Optical Layer Routing
State: Pending
Authors: John Strand, Angela Chiu

Date: 2003-05-08
Optical networking poses a number challenges for GMPLS. Optical technology
is fundamentally an analog rather than digital technology; and the optical
layer is lowest in the transport hierarchy and hence has an intimate
relationship with the physical geography of the network. This contribution
surveys some of the aspects of optical networks which impact routing and
identifies possible GMPLS responses for each: (1) Constraints arising from
the design of new software controllable network elements, (2) Constraints
in a single all- optical domain without wavelength conversion, (3)
Complications arising in more complex networks incorporating both
all-optical and opaque architectures, and (4) Impacts of diversity
constraints.
