This object indicates the number of one-way messages
successfully delivered to the end point. This count includes
only those messages that do not require a response from the end
point. However in case the AON node is not the exit node but
rather an entry or intermediate node hop in the AON cloud then
this counter represents successful delivery to the next
hop.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other times
as indicated by the value of caonCounterDiscontinuityTime
object.
