MsgConnect

MsgConnect is indispensable if your application consists of more than one module. If you need to exchange information between modules, no matter within one system or across network, MsgConnect will solve this problem for you. You can use simple paradigm of sending binary message to the remote side and MsgConnect will deliver the message and reply with optional compression, encryption and integrity checking.
MsgConnect is a cross-platform network message queue framework (message-oriented middleware), similar to Java message queue or MS message queue with the difference that MsgConnect can work in peer-to-peer mode (without any server). MsgConnect encapsulates low-level transport protocols (currently HTTP, TCP, UDP, memory-mapped-files) and provides uniform API for exchanging binary messages on single system or across network. The framework can be used both in peer-to-peer and client-server applications. With MsgConnect you will be able to concentrate on business logic of your application and avoid the need to deal with low-level tasks like splitting the data stream into messages or providing reliable encryption.
MsgConnect is available for variety of platforms and development tools including Windows (Delphi, C++, DLL/ActiveX, .NET), Linux/Unix/QNX (Kylix, C++/gcc), Windows CE, Palm OS, Java 2 SE/EE, Java ME (cell phones). You can choose from open source and commercial licensing. Commercial license includes AES encryption, ZLib compression and CRC32/Adler32/MD5 integrity checking.
