摘要
A consensus is emerging in industry on utilizing an IP-Centric control planewithin optical networks to support dynamic provisioning and restoration of light paths. At the sametime, there are divergent views of how IP routers interact with optical core networks to achieveend-to-end connectivity. This paper describes the strategies of optical communication s futuredevelopment towards next generation IP over Optical Networks. The desirable extent of networktransparency in advanced all-optical network architecture is studied. Architectural alternatives forinterconnecting IP routers over optical networks, and the concerned routing and signaling issuesare described.
