=head1 NAME

  NormalInitClient.seq - Normal Association of SCTP Client

=head1 PURPOSE

  To check the normal association procedure of SCTP Client.

=head1 SYNOPSIS

=begin html
<PRE>
  <A HREF="./NormalInitClient.seq">./NormalInitClient.seq</A> [-tooloption ...] -pkt <A HREF="./NormalInitClient.def">./NormalInitClient.def</A>
    -tooloption : v6eval tool option

</PRE>

=end html

=head1 PRE-TEST CONDITION

  Association not established between endpoint A and B. Also arrange the
  data in endpoint B such that upper layers send Associate primitive to
  startup an association with endpoint A.

=head1 TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (CLOSED)                             (CLOSED)

                                                   <-----    Associate
                <-----------------      INIT

  INIT-ACK      ----------------->

                <-----------------      COOKIE-ECHO

  COOKIE-ACK    ----------------->

                <-----------------      DATA

  SACK          ----------------->

  TEST DESCRIPTION:

  1. Start normal association procedure by sending associate primitive 
     from ULP in endpoint B.Record the message sequence using a signal 
     emulator.
  2. Check A: Association is established.
  3. Check B: First data chunk sent after establishing association is 
     immediately acknowledged by SACK.
  4. Check C: Reception and transmission of various length data chunks on
     the established association.
  5. Check D: All the DATA messages are received correctly. (No loss of 
     messages.)
