Hi,

I want to know the purpose of the active path time out in the HWMP
protocol. I got different information from different sources and I was
confused with the operation. Here is the information I have:
In the open80211s implementation, after a path is being created, a timer
gets initialized and the path remains valid until *timeout* seconds. After
the timeout, if a new data packet needs to be sent, then a PREQ is
unicasted to the destination but not broadcasted. But in the ns-3
simulator, PREQ's are broadcasted. From the IEEE 802.11-2012 standard, this
is what I got:
"This attribute specifies the time (in TUs) for which mesh STAs receiving a
PREQ to individual target(s) shall consider the forwarding information to
be valid."
Frankly, I could not understand what the standard document said. So, if
anyone could give me more information about the HWMP active path timeout
parameter, It would be really helpful for my research project. Thank you.

Regards,
Siva.
