This document specifies the requirements of an MPLS Transport Profile (MPLS-TP). This document is a product of a joint effort of the International Telecommunications Union (ITU) and IETF to include an MPLS Transport Profile within the IETF MPLS and PWE3 architectures to support the capabilities and functionalities of a packet transport network as defined by International Telecommunications Union-Telecommunications Standardization Sector (ITU-T). This work is based on two sources of requirements: MPLS and PWE3 architectures as defined by IETF, and packet transport networks as defined by ITU-T. The requirements expressed in this document are for the behavior of the protocol mechanisms and procedures that constitute building blocks out of which the MPLS Transport Profile is constructed. The requirements are not implementation requirements. Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
This document provides an overview of the Operations, Administration, and Maintenance (OAM) toolset for MPLS-based transport networks. The toolset consists of a comprehensive set of fault management and performance monitoring capabilities (operating in the data plane) that are appropriate for transport networks as required in RFC 5860 and support the network and services at different nested levels. This overview includes a brief recap of the MPLS Transport Profile (MPLS-TP) OAM requirements and functions and the generic mechanisms created in the MPLS data plane that allow the OAM packets to run in-band and share their fate with data packets. The protocol definitions for each of the MPLS-TP
Requirements and use cases for the 5G era are demanding in key dimensions such as throughput, latency, scalability and automation. From these, an end-to-end architectural vision has been developed in a holistic way and including novel architectural concepts including 5G access domain and 5G era horizontal layers in conjunction with cloud, software defined and cognitive networks transformation. End-toend architecture for the 5G era is decomposed in a systematic manner, key attributes and characteristics of the associated architectural domains are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
