Application Specific Topology Builder (ASTB)
ASTB provides an API which is utilized by applications to request network services. Applications can use
this API to request a dynamic path set up across an DRAGON enabled network. This API includes a
simple message set to allow an application to request a dedicated network path between a specified
source/destination pair identified by IPv4 addresses. In future releases, the ASTB will provide a more
general "topology builder" functionality. This will allow an application to request a topology to be built
which consists of multiple point to point LSPs in a user specified configuration. This release includes the
first building block of that larger vision by allowing a single LSP specification per request.
The interface to the ASTB API is via XML/SOAP objects using HTTP as transport. The application may be another
computer program or a web browser driven by human interaction. This release of the DRAGON Software
Suite includes both the standard message set API as well as a web browser control interface. The ASTB
also utilizes the ESA API to translate user requests into end-system protocol provisioning actions.
The ASTB code is incorporated into the DRAGON software releases. Please see the GMPLS Control Plane Software
page maintained by University of Southern California (USC) Information Sciences Institute (ISI) East
to download the latest stable release.
