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].

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


   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).
