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)
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.(More)
This document describes an architecture for extending pseudowire emulation across multiple packet switched network (PSN) segments. Scenarios are discussed where each segment of a given edge-to-edge emulated service spans a different provider's PSN, as are other scenarios where the emulated service originates and terminates on the same provider's PSN, but(More)
This document specifies an Inter-Chassis Communication Protocol (ICCP) that enables Provider Edge (PE) device redundancy for Virtual Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS) applications. The protocol runs within a set of two or more PEs, forming a Redundancy Group, for the purpose of synchronizing data among the systems. It(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)
RFC 5254 describes the service provider requirements for extending the reach of pseudowires (PWs) across multiple Packet Switched Network domains. A multi-segment PW is defined as a set of two or more contiguous PW segments that behave and function as a single point-to-point PW. This document describes extensions to the PW control protocol to dynamically(More)
Virtual Private Networks (VPN) are a popular way for enterprises to interconnect remote sites. Traditionally, VPNs have been based on Frame Relay, Asynchronous Transfer Mode (ATM) or Time Division Multiplex (TDM) private lines, using the service provider's ATM core network, and accounting for the majority of their data service revenues. However, the(More)
Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document describes the necessary requirements to allow a service provider to extend the reach of pseudowires across multiple domains. These domains can be autonomous(More)
