To each optical channel that carries distinct digital client signals through these optical pipes, OTN provides the functions of transport, multiplexing, routing, management, supervision and survivability. These OTN technologies that have been successful to handle large transport pipes in point-to-point connections are now much more successful as a new switching technology. The use of such large panel of data contents is eased by an efficient and optimal provisioning. The control plane has reused most of the concept and implementation of the SONET Control plane taking thus advantages of deployment feedback.

In automatic switched transport networks ASTN , transport services of different granularity can be set up, modified and released on demand using the mechanisms in the control plane. Currently, this novel provisioning paradigm is being standardized under the umbrella of the automatic switched optical network ASON and generalized multiprotocol label switching GMPLS framework.
This paper provides an overview of the ASON and GMPLS frameworks at the current stage of their development and aims in particular on comparing the concepts and pointing out some open issues. In this context, we first give a brief overview of ASON and GMPLS work, and then provide a concept and functionality mapping including network resource models, control plane architecture, discovery, call and control management, and resiliency.
Finally we address some important provider requirements. This is a preview of subscription content, log in to check access. Rent this article via DeepDyve. ITU-T Rec. Awduche, Y. Google Scholar.

ASON and GMPLS—Overview and Comparison
ASON / GMPLS for OTN switching platforms
Traditionally, creating traffic paths through a series of Network Elements has involved configuration of individual cross-connects on each Network Element. ASTN allows the user to specify the start point, end point and bandwidth required, and the ASTN agent on the Network Elements will allocate the path through the network, provisioning the traffic path, setting up cross-connects, and allocating bandwidth from the paths for the user requested service. The actual path that the traffic will take through the network is not specified by the user. This gives the user far more flexibility when allocating user bandwidth to provide services demanded by the customer. From Wikipedia, the free encyclopedia. Computer network protocol.
