MSMQ
Microsoft Message Queuing (MSMQ) is a messaging protocol developed by Microsoft that enables applications running at different times to communicate across heterogeneous networks and systems that may be temporarily offline. It provides guaranteed message delivery, efficient routing, security, and priority-based messaging, facilitating reliable distributed application development and integration within enterprise environments..
Microsoft Message Queuing (MSMQ) is a message-based communication platform designed to enable applications on disconnected or distributed systems to communicate asynchronously. It employs a store-and-forward mechanism that ensures messages are held in queues until the receiving application is available. This design supports robust messaging in environments prone to network fluctuations or temporary outages.
MSMQ operates over TCP port 1801 for direct communication and can use UDP for certain multicast operations. It integrates deeply with Windows operating systems, providing APIs for message queuing and management. Features include transactional messaging to ensure atomic delivery, message journaling, priority-based message handling, and support for both private and public queues.
The technology facilitates scaling by decoupling the communication between components of distributed applications. It is widely used in enterprise solutions, including financial services, supply chain management, and service-oriented architectures, where reliable, asynchronous message exchange is required between heterogeneous systems.
