Simple Path Control Protocol Specification

• IETF Draft by D. Lillethun, J. Lange, J.
  Weinberger (iCAIR)
• (Refwww.ietf.org)
• The Simple Path Control Protocol (SPC) defined
  in this document is a new protocol defined to
  enable processes external to networks to
  establish, delete and monitor paths, including
  lightpaths. The architecture of this protocol
  establishes a method of providing messages, and
  procedures that allow such external processes to
  directly request network resources related to
  path provisioning.
• Various methods exist that allow paths,
  including lightpaths, to be
• established within a network. The Simple
  Path Control Protocol was developed to enable
  external processes, including applications, to
  communicate messages that allow for such paths to
  be created, deleted and monitored. SPC defines a
  message that can be sent to a server that is
  capable of establishing a path on lower-layer
  network elements. After receiving such a request,
  the server is responsible for identifying the
  appropriate path through the controlled network
  topology and configuring it to fulfill the
  request. SPC also provides facilities for
  explicitly releasing a path when it is no longer
  needed, and for simple query facilities about the
  current network state.
