 Requirements for Very Fast Setup of GMPLS Label Switched Paths (LSPs)

Abstract

   Establishment and control of Label Switch Paths (LSPs) have become
   mainstream tools of commercial and government network providers.  One
   of the elements of further evolving such networks is scaling their
   performance in terms of LSP bandwidth and traffic loads, LSP
   intensity (e.g., rate of LSP creation, deletion, and modification),
   LSP set up delay, quality-of-service differentiation, and different
   levels of resilience.

   The goal of this document is to present target scaling objectives and
   the related protocol requirements for Generalized Multi-Protocol
   Label Switching (GMPLS).

RFC 7709              Very Fast Setup of GMPLS LSPs        November 2015

1.  Introduction

   Generalized Multi-Protocol Label Switching (GMPLS) [RFC3471]
   [RFC3945] includes an architecture and a set of control-plane
   protocols that can be used to operate data networks ranging from
   packet-switch-capable networks, through those networks that use Time
   Division Multiplexing, to WDM networks.  The Path Computation Element
   (PCE) architecture [RFC4655] defines functional components that can
   be used to compute and suggest appropriate paths in connection-
   oriented traffic-engineered networks.  Additional wavelength switched
   optical networks (WSON) considerations were defined in [RFC6163].

   This document refers to the same general framework and technologies,
   but it adds requirements related to expediting LSP setup under heavy
