A hack implementation of something similar to a DCE UUID
generator. Generates unique 128-bit numbers based on the
current machine's internet address, the current time, and
a sequence number. This implementation should be made to
conform to the DCE specification. ("DEC/HP, Network Computing
Architecture, Remote Procedure Call Runtime Extensions
Specification, version OSF TX1.0.11," Steven Miller, July
23, 1992. This is part of the OSF DCE Documentation.
Chapter 10 describes the UUID generation algorithm.)
Some known deficiencies:
- Rather than using the 48-bit hardware network address,
it uses the 32-bit IP address. IP addresses are not
guaranteed to be unique.
- There is no provision for generating a suitably unique
number if no IP address is available.
- Two processes running on this machine which start their
respective UUID services within a millisecond of one another
may generate duplicate UUIDS.
However, the intention is that UUIDs generated from this class
will be unique with respect to UUIDs generated by other DCE
