The CCAMP working group is pleased to inform you of the publication of RFC
4258: "Requirements for Generalized Multi-Protocol Label Switching (GMPLS)
Routing for the Automatically Switched Optical Network (ASON)"

The abstract of this RFC is as follows.

   The Generalized Multi-Protocol Label Switching
   (GMPLS) suite of protocols has been defined to
   control different switching technologies as well
   as different applications.  These include support
   for requesting Time Division Multiplexing (TDM)
   connections including Synchronous Optical Network
   (SONET)/Synchronous Digital Hierarchy (SDH) and
   Optical Transport Networks (OTNs).

   This document concentrates on the routing
   requirements placed on the GMPLS suite of
   protocols in order to support the capabilities
   and functionalities of an Automatically Switched
   Optical Network (ASON) as defined by the ITU-T.

The CCAMP working group is indebted to several members of the ITU-T SG15
community who played a significant part in the authorship of this RFC, and to
Question 14/15 which provided important review feedback to ensure that this
document accurately reflects the nature and requirements of routing in an ASON
