Introduction
OSI standards: Since OSI/AS implements several OSI International standards, the
format, content and order of trace records in a trace file will reflect those standards.
Depending on which trace records are being examined, knowledge of the structure
and content of OSI PDUs is necessary to fully understand the contents of the trace
file. The following OSI standards provide related information:
