Abstract
The data demands and economics surrounding IP internetworking are such that IP routers are now connecting directly to SDH or DWDM systems. As such, many of the traditional mechanisms used to engineer the traffic over the physical infrastructure are no longer available. Consequently a new approach is required. This paper outlines a set of mechanisms and procedures, including enhancements to the layer 3 routeing and signalling protocols ad MPLS forwarding that, when combined, provide the capabilities to provide traffic engineering capabilities in an optical IP environment.
