Static and Dynamic identifiers

The IPC location-transparent communication service is based on a uniform global naming scheme. Communication entities are named using global unique identifiers. Two types of global identifiers are distinguished:

• Static identifiers, provided to the system by the applications

• Dynamic identifiers, returned by the system to the application

Static identifiers are built deterministically from stamps provided by the applications. On a single site, only one communication object can be created with a given static identifier in the same communication feature. The maximum number of static stamps is fixed.

Network-wide dynamic identifiers, assigned by the system, are guaranteed to be unique across site reboots for a long time. The dynamic identifier of a new communication object is initially only known by the actor that creates the communication object. The actor can transmit this identifier to its clients through any application-specific communication mechanism (for example, in a message returned to the client).
