|If we drill down
into the information flow of that one particular information flow . . .
information flow, we can develop a communications view diagram that
illustrates the stack of protocols that implement the flow.
|If 5.9 GHz DSRC is
used, the RSE might not be part of the flow on the physical diagram, but does
serve as a network access point so it appears here, as it does pass the
are shown in between the protocol stacks. For a signed, encrypted message,
the message is built, encoded, signed, encrypted and then shipped out UDP/IP.
|This kind of
diagram allows us to trace the flow of data across boundaries of different
elements in the system.
