developped by Motorola. 
Further details about these services will be given in the following sections. 
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 
 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 
 of this manual.
