Middleware
Middleware is a type of computer software that provides services to software applications beyond those available from the operating system. It can be described as "software glue". Middleware makes it easier for software developers to implement communication and input/output, so they can focus on the specific purpose of their application. It gained popularity in the 1980s as a solution to the problem of how to link newer applications to older legacy systems, although the term had been in use since 1968. In distributed applications The term is most commonly used for software that enables communication and management of data in distributed applications. An IETF workshop in 2000 defined middleware as "those services found above the transport (i.e. over TCP/IP) layer set of services but below the application environment" (i.e. below application-level APIs). In this more specific sense ''middleware'' can be described as the dash ("-") in '' client-server'', or the ''-to-'' in '' ...

HP RTR
HP Reliable Transaction Router (RTR) is a transactional middleware for computer software, marketed by Hewlett Packard. RTR is used to integrate with applications that require reliable transaction services. Description RTR manages the messages which are sent between client-server to provide node and network fail-over for increased reliability, transactional integrity, and interoperability between dissimilar systems. The RTR software has three logical entities and referred to as front-end (FE), back-end (BE) and transaction-router(TR). The router is a software component that provides the fail-over intelligence and manages connections to the back-end. The client applications running on the Front-End combined with Router and Server applications running on back-end interact to provide transaction integrity and reliability. The three logical entities can exist on the same node but are usually deployed on different nodes to achieve modularity, scalability and high availability. The ...
