1.  Introduction

   Once an existing multiprotocol label switching (MPLS) traffic
   engineering (TE) label switched path (LSP) is set up, it is assumed
   to carry traffic forever until it is down.  When an MPLS TE LSP
   tunnel is up, it is assumed that the LSP consumes its reserved
   network resources forever even though the LSP may only use network
   resources during some period of time.  As a result, the network
   resources are not used efficiently.  Moreover, a tunnel service can
   not be reserved or booked in advance in a period of time.
