Re: [STDS-802-16] The ARP broadcast problem in 802.16
If you could use the SMC for ARP traffic of an MSS, then yes, the
problem you describe would exist.
However the secondary management channel was removed for MSSs in the San
Antonio meeting. So text specifying an MSS must the the SMC for
something sounds inconsistent with that.

Subject: [STDS-802-16] The ARP broadcast problem in 802.16
Hi all,
I have a question about the ARP operation in 802.16 network. In
contribution named "BS's Proxy ARPing for Sleep & Idle Mode MSSs", it
mentioned that the ARP request message will be carried over secondary
management connection. The problem is that secondary management
connection in DL is an unicast connection, if the BS broadcasts the ARP
request message through secondary management connection, it means that
each SS will receive an duplicate ARP request message from the BS, which
is obvious not bandwidth efficient. Is there any misunderstanding of my
reading of the standard?
Thank you.
Best Regards,
