================ MQ4CPP ======================= Project: Message Queuing for C++ Copyright (C) 2004-2007 Riccardo Pompeo (Italy) http://www.sixtyfourbit.org mailto:riccardo.pompeo@sixtyfourbit.org =============================================== DESCRIPTION =========== MQ4CPP, or "Message Queuing for C++", is an open source implementation of enterprise messaging system, also referred to as message-oriented middleware (MOM). MQ4CPP enables C++ application threads to communicate with other threads locally or remotely through the exchange of messages. A message is a request, report, and/or event that contains information needed to coordinate communication between different applications. A message provides a level of abstraction, allowing you to separate the details about the destination system from the application code. Specifically, MQ4CCP: - enables C++ applications sharing a messaging system to exchange messages - simplifies application development by providing a standard interface for creating, sending, and receiving messages. MQ4CPP implements the following messaging paradigms: - Direct/Indirect messaging - Unsolicited messaging - Request/Reply - Reliable messaging - Automatic reconnection - Connection failover on multiple servers - Conversation - Broadcast - Publish/Subscribe - Store&Forward - Message routing - Local routing - Remote routing - Topic driven switching MQ4CPP implements also the following services: - Advanced tracing for multi-threading debugging: - Send debug messages to stdout - Send debug messages to Microsoft WinDbg - Thread safe garbage collector. - Performant implementation of LinkedList and Vector patterns. - Timer (single shot, self-repeating). - Thread safe logger. - Deferred queuing to avoid thread locks or infinite looping. - Lookup service: - Local services - Remote services - Local and remote threads referenced by handle. - Automatic clean-up of network connections. - Threads reuse same socket connections. - Socket transmission: - TCP protocol - statistical multiplexing on a single connection - packets limited to 65 Kbytes to avoid hacking via buffer overflow attacks. - packets associated to a sequence number. - Session management: - session repository - session replication between multiple server - Message encription: - Rijndael 128 - Rijndael 256 - Ready for more - Message compression As implementation of Request/Reply MQ4CPP include also: - Distributed lock manager to allow multiple threads share any resources - File transfer to transfer file between threads - Distributed memory channel to transfer big amount of memory (for example a cache) between threads. In './docs' directory are included the following resources: - 'class_diagram_*.png': UML class diagrams - 'mq4cpp.pdf': Description of implemented paradigms, main class diagrams and interaction diagrams of included examples In './examples' directory are included some example programs, one for each implemented paradigm. I suggest you to read before 'mq4cpp.pdf' and than customize an example program to start your application integration project using MQ4CPP framework.
