[Lksctp-developers] ARP request being sent every 20 seconds or so

[upma g. <upm...@gm...>]

Hello All,
  I have one basic SCTP client and server ( having single network
connection) and client is continuously sending data to server every 1
second. I am seeing that server is sending ARP request every 20
seconds or so ( see below logs) for client IP address. If I use TCP
client/ server  instead of SCTP, I see that ARP request is being sent
every 4 minute. Can somebody clarify why its happening or if my
observation is wrong ?

Thanks
