Subject: Re: Question on SCTP ABORT chunk is generated when the
 association_max_retrans is reached

Hi

sorry for the late reply. I am a bit confused. when side-A sends a
request to side-B, and side-B return the response, but side-A keep
re-transmit the same request to side-B, why side-B needed to send a
ABORT to side-A?

If it is used in order to reestablish the connection, shoudn't it
should be side-A to send ABORT instead?

- PS
