Qnet symlink manager (QSM)

Qnet is a QNX Neutrino protocol for communication between processes residing on different nodes. It enables IPC to work across nodes. For example, LWM uses Qnet transparently to enable inter-node communication.

The use of a symbolic link (symlink) enables location transparency to the Qnet protocol. When a process needs to communicate with another process, it uses the symlink associated with the service and does not need to know where the service is located. A server process registers with Qnet symlink manager (QSM) and publishes its service using symlink.
