Re: [SCTP] clarification about HB.Max.Burst parameter

Hi Ashwani,

 

When RTO expires for an address, your path probing module will get
chance to send HEARTBEATS to other UNCONFIREMD addresses as well (NOT
only to the address for which RTO has expired) limited by HB.Max.Burst
parameter.

 

Hope this helps.

 

Regards,

-Ashish

Subject: [Sigtran] [SCTP] clarification about HB.Max.Burst parameter

 

Hello All,

 

SCTP RFC 4690 has mentioned a parameter HB.Max.Burst.

As per RFC 4960 section 4.5 :

   The number of HEARTBEATS sent at each RTO SHOULD be limited by the
   HB.Max.Burst parameter.

 

During the Path verification when an RTO expires, SCTP will re-send the
Heartbeat to that address.

Please clarify me, how HB.Max.Burst parameter will control the number of
Heartbeat sent to that address.

Shouldn't the number of Heartbeat send to a particular address at any
time will always be 1? 

If Yes, then why HB.Max.Burst is required?

If No, then please make me understand that how this parameter is used.

 

Thanks & Regards,

Ashwani Kathuria
