opendxl added a new solution:
The File Transfer DXL Python client library provides the ability to transfer files via the Data Exchange Layer (DXL) fabric.
OpenDXL brokers are configured by default to limit the maximum size of a message to 1 MB. The File Transfer DXL Python client allows the contents of a file to be transferred in segments small enough to fit into a DXL message.
This client can be used in conjunction with the File Transfer DXL Service, an application which registers a service with the DXL fabric and a request callback which can store files sent to it.
See the Wiki for an overview of the File Transfer API DXL Python client library and usage examples.
See the File Transfer DXL Python client documentation for installation instructions, API documentation, and usage examples.
