An Overview of ITO Processes
Understanding ITO Processes
Understanding ITO Processes
ITO’s agents and managers communicate by means of Remote Procedure
Calls (RPCs) based on DCE or NCS, files (=queues), pipes, or signals.
These mechanisms apply to communication between the management
server and the managed nodes as well as to communication between
processes running locally on the management server.
