This document specifies an architectural framework for the application of Multiprotocol Label Switching (MPLS) to the construction of packet-switched transport networks. It describes a common set of protocol functions-the MPLS Transport Profile (MPLS-TP)-that supports the operational models and capabilities typical of such networks, including signaled or(More)
In recent years, significant work has been completed on traffic engineering enhancements to the generalized multiprotocol label switching protocol suite (E. Mannie Oct 2004) (D. Katz et al., Sept. 2003) (K. Kompella et al., Oct 2003). As a next step, reproducing the current trend of switching layers' integration happening in the data plane, network control(More)
The framework for MPLS in transport networks (RFC 5921) provides reference models for the MPLS Transport Profile (MPLS-TP) Transport Service Interfaces, which are a User-to-Network Interface (UNI), and a Network-to-Network Interface (NNI). This document updates those reference models to show detailed reference points for these interfaces, along with further(More)

framework of the research project NOBEL (Next generation Optical networks for Broadband European Leadership), funded by the European Commission through the IST Program. The NOBEL project has the goal to design and validate the target architecture for an intelligent and agile optical network, which will enable ubiquitous broadband end-to-end services, based(More)
