Ice is a modern alternative to object middleware such as CORBA or COM/DCOM/COM+. It is easy to learn, yet provides a powerful network infrastructure for demanding technical applications. It features an object-oriented specification language, easy to use C++ and Java mappings, a highly efficient protocol (including protocol compression), asynchronous method invocation and dispatch, dynamic transport plug-ins, TCP/IP and UDP/IP support, SSL-based security, a firewall solution, and much more.
COID is an object-oriented networking library with a tool that automatically generates a lightweight communication layer directly from a C++ class declaration. The coidgen tool automatically extracts designated classes and methods from specified header files and generates a corresponding client class and host dispatcher. The server library manages networked and local connections and provides various services to running objects. The communication layer establishes either remote connection through TCP or direct (vtable) connection between the client and the server (if they reside in the same process).
Channel is a C++ template framework for distributed message passing and event dispatching. Its major components (message IDs, routing algorithms...) are highly configurable as template parameters. As a namespace shared by peer threads, channels support publish/subscribe scope control, message filtering, and translation.
Keystone is a cross-platform, object oriented application framework which allows applications to be written to build on the target platforms of GNU/Linux and Win32 without modification of their source. Keystone implements several modern Web standards, including SVG graphics and the XUL user interface description language.
