Application Level Network Tracking Attribute

      A mechanism is described which allows keeping track of
where a distribution has been during the path from sender to
recipient.

      It is useful for determining the exact path a distribution
traversed to get delivered in a complex world of connectivity.
Knowing distribution paths and network hops provide a means to
identify efficient routing paths and prevent inefficient routing
paths. This attribute should only be used when troubleshooting or
verifying network traffic. Routing applications will identify
themselves in a historical manifestation part of attribute
information associated with the distribution. This article describes
an architected attribute which logically consists of a log of history
information updated as the associated distribution flows through the
network. The history information is not limited to but will at least
consist of the following tracking attributes:
1)   OPEN BRACKET DATE/TIME STAMP - to be added to the tracking
attribute at each receiving system immediately before adding other
data within the attribute.
2)   SYSTEM IDENTIFIER - An identifier which uniquely identifies the
reporting system (e.g., performed a store and forward (SNA/DS), an
RSC link (DISOSS to/from VMPROFS), etc.).
3)   SOURCE ADDRESS
4)   RECIPIENT ADDRESSES
5)   MANIPULATION SPECIFIC DATA (e.g., attribute format changes, code
page transforms, document content modification (e.g., updated in
response to reply/forward/etc.).
6)   CLOSE BRACKET DATE/TIME STAMP - to be added to the attribute
after receiving systems added all their data within the attribute.
