Transparent Inter Process Communication (TIPC) is a protocol specially designed for efficient intra cluster communication, leveraging the particular conditions present within clusters of loosely coupled nodes.
TIPC provides a powerful infrastructure for designing distributed, site-independent, scalable, highly-available and high-performing applications, as well as a good support for cluster, network and software management functionality. In this paper, we will discuss the motives for developing TIPC and describe its architecture. Then, we will present the most important features of TIPC, such as its functional, location transparent, addressing scheme, lightweight reactive connections, reliable multicast, signalling link protocol, topology subscription services and more. We will also discuss the various design decisions that influenced the implementation of these features. We conclude by describing the current implementation status and our planned roadmap for TIPC.
