2.1.2
Message Distribution Service
The Message Distribution Service (MDS) provides high-performance, reliable message
distribution services. NCS services and user applications invoke the services provided by MDS
through an API which is exposed in the form of a library that can be linked to a process. MDS
supports intra-process, inter-process as well as inter-node communication. Further details
about MDS will be given in section
distribution services. NCS services and user applications invoke the services provided by MDS
through an API which is exposed in the form of a library that can be linked to a process. MDS
supports intra-process, inter-process as well as inter-node communication. Further details
about MDS will be given in section
of this manual.
2.1.3
LEAP Portability Layer
LEAP stands for Layered Environment for Accelerated Portability. It is an operating system
abstraction that provides portability to both NCS services and user applications from underlying
operating system specifics and provides many value-added features. Further details are given
in section
