TUBE® Services

A TUBE server provides the entry-points for the APIs. Systems that work through TUBE will either use the TUBE API or, alternatively, their own middleware API, and have these calls intercepted and processed by a TUBE interceptor.
A Message Distribution Service associates requests for a service with a particular protocol. It determines the source and target protocols to be used and the end-points for requests. The Message Distribution Service requests data marshaling and un-marshaling, and requests message transmission. When a response is received, it is un-marshaled and passed back to the source.
