Message-oriented middleware

Type of software or hardware infrastructure Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. Message-oriented middleware is in contrast to streaming-oriented middleware where data is communicated as a sequence of bytes with no explicit message boundaries. Note that streaming protocols are almost always built above protocols using discrete messages such as frames (Ethernet), datagrams (UDP), packets (IP), cells (ATM), et al. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. Application programming interfaces (APIs) that extend across diverse platforms and networks are typically provided by MOM. This middleware layer allows software components (applications, servlets, and other components) that have been developed independently and might run on different networked platforms to inte
