  ./AbortInEstab.seq [-tooloption ...] -pkt ./AbortInEstab.def
    -tooloption : v6eval tool option
  See Also: ../common/STD_PKT_COMMON.def
            ../common/SCTP_COMMON.def
=end html =head1 PRE-TEST CONDITION Association is established between endpoint A and B. Arrange the data in endpoint A such that an ABORT message is sent to endpoint B. =head1 TEST PROCEDURE Endpoint A Endpoint B ULP (ESTABLISHED) (ESTABLISHED) ABORT -----------------> Association is removed Communication Lost ---------> TEST DESCRIPTION: 1. Attempt to terminate an association between endpoint A and endpoint B by sending ABORT message. 2. Check A: No Acknowledgement is sent for the ABORT message and association is removed. 3. Check B: ULP are reported of the association closure. =head1 NOTE None =head1 REFERENCE RFC 4960 9.1. Abort of an Association When an endpoint decides to abort an existing association, it MUST send an ABORT chunk to its peer endpoint. The sender MUST fill in the peer's Verification Tag in the outbound packet and MUST NOT bundle any DATA chunk with the ABORT. If the association is aborted on request of the upper layer, a User-Initiated Abort error cause (see Section 3.3.10.12) SHOULD be present in the ABORT chunk. An endpoint MUST NOT respond to any received packet that contains an ABORT chunk (also see Section 8.4). An endpoint receiving an ABORT MUST apply the special Verification Tag check rules described in Section 8.5.1. =begin html
    After checking the Verification Tag, the receiving endpoint MUST
    remove the association from its record and SHOULD report the
    termination to its upper layer.  If a User-Initiated Abort error
    cause is present in the ABORT chunk, the Upper Layer Abort Reason
    SHOULD be made available to the upper layer.
