ASTN

ASTN (Automatic Switched Transport Network) allows traffic paths to be set up through a switched network automatically. The term ASTN replaces the term ASON (Automatically Switched Optical Network) and is often used interchangeably with GMPLS (Generalized MPLS). This is not completely correct as GMPLS is a family of protocols and ASON/ASTN an optical network that relies on GMPLS and adds more protocols to extend the protocol suite. Furthermore, the GMPLS protocols are applicable to optical and non-optical (e.g., packet and frame) networks, are can be used in transport or client networks. Thus, GMPLS is a wider concept than ASTN.
