Routing in Optical Networks, Multilayer Networks, and Overlay Networks

Two roads diverged in a wood, and I –

I took the one less traveled by,

And that has made all the difference.

Robert Frost


This chapter addresses routing issues in a number of related environments. We first start with routing in optical networks. Optical networks provide the core infrastructure for Internet services across the world, including submarine cables that connect continents via oceans. We discuss in general, how routing in optical networks works for a number of optical network technologies. We then present routing in multilayer newtorks and overlay networks.
