- MPLS-TP
MPLS-TP or MPLS Transport Profile is a
profile of MPLS whose definition has been commenced theIETF . It will be designed for use as a network layer technology in transport networks. Its design will be a continuation of the work started by the transport network experts of theITU-T , specifically SG15, asT-MPLS with the required protocol extensions to MPLS being specified by the IETF. It will be a connection-oriented packet-switched (CO-PS) application. It will offer a dedicated MPLS implementation by removing features that are not relevant to CO-PS applications and adding mechanisms that provide support of critical transport functionality.MPLS-TP is to be based on the same architectural principles of layered networking that are used in longstanding transport network technologies like SDH, SONET and OTN. Service providers have already developed management processes and work procedures based on these principles.
MPLS-TP will provide service providers with a reliable packet-based technology that is is based upon circuit-based transport networking, and thus is expected to align with current organizational processes and large-scale work procedures similar to other packet transport technologies.
MPLS-TP is expected to be a low cost L2 technology (if the limited profile to be specified is implemented in isolation) that will provide QoS, end-to-end OA&M and protection switching.
In february 2008 the
ITU-T andIETF agreed to work jointly [cite web
