The Object Transport Layer (OTL) is a central component of the system architecture. It is designed to support the operation and inter-operation of a variety of programming models, including: traditional CORBA-style object systems, systems with more complex distributed or fragmented objects, and explicitly reactive object systems like the Event Reaction Architecture.
A preliminary version of OTL is working, based on our Datahub communications package and Ithreads user-level threads package. This version interprets a limited set of attributes and is capable of performing threaded or non-threaded remote object invocations and transporting uninterpreted parameter blocks.
We have also begun moving some applications onto the OTL. As this process proceeds we are refining the OTL and extending the set of attributes through which it can be configured.
