Segment Routing Architecture
Segment Routing (SR) leverages the source routing paradigm. A node steers a packet through an ordered list of instructions, called segments. A segment can represent any instruction, topological orExpand

IP Fast Reroute using tunnels
This draft describes an IP fast re-route mechanism that provides backup connectivity in the event of a link or router failure. In the absence of single points of failure and asymmetric costs, theExpand

Application-Layer Traffic Optimization (ALTO) Protocol
Applications using the Internet already have access to some topology information of Internet Service Provider (ISP) networks. For example, views to Internet routing tables at Looking Glass serversExpand

North-Bound Distribution of Link-State and Traffic Engineering (TE) Information Using BGP
In a number of environments, a component external to a network is called upon to perform computations based on the network topology and current state of the connections within the network, includingExpand

Remote Loop-Free Alternate (LFA) Fast Reroute (FRR)
This document describes an extension to the basic IP fast reroute mechanism, described in RFC 5286, that provides additional backup connectivity for point-to-point link failures when none can beExpand

A Framework for IP and MPLS Fast Reroute Using Not-Via Addresses
This document presents an illustrative framework for providing fast reroute in an IP or MPLS network through encapsulation and forwarding to "not-via" addresses. The general approach described hereExpand

Source Packet Routing in Networking (SPRING) Problem Statement and Requirements
The ability for a node to specify a forwarding path, other than the normal shortest path, that a particular packet will traverse, benefits a number of network functions. Source-based routingExpand

OSPF Extensions for Segment Routing
Segment Routing (SR) allows a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological sub-paths, called "segments". These segments are advertisedExpand

Routing Extensions for Discovery of Multiprotocol (MPLS) Label Switch Router (LSR) Traffic Engineering (TE) Mesh Membership
The setup of a full mesh of Multi-Protocol Label Switching (MPLS) Traffic Engineering (TE) Label Switched Paths (LSP) among a set of Label Switch Routers (LSR) is a common deployment scenario of MPLSExpand
