This application illustrates an application-level Gateway which routes
messages between Consumer and Suppliers in a distributed environment.
The default configuration is single-threaded, i.e., all
Supplier_Proxys and Consumer_Proxys are multiplexed via the ACE
Reactor within a single thread of control. To obtain a version that
multi-threads both Consumer_Proxys and Supplier_Proxys simply set
the following flag in the Makefile:
DEFFLAGS += -DUSE_OUTPUT_MT -DUSE_INPUT_MT
To get a version that uses single-threading for all Supplier_Proxys,
but a separate thread per-Consumer_Proxy set the following flag in
the Makefile:
DEFFLAGS += -DUSE_OUTPUT_MT
If you examine the source code, you'll see that very few changes are
required in the source code to switch between single-threading and
multi-threading. The ACE Task class is primarily responsible for
enabling the flexible modification of concurrency strategies with only
minor changes required to the source code, design, and system
architecture.
