NAME

  BundledAsconfAndOther.seq - ASCONF chunk is received bundled with other chunk as the first chunk

PURPOSE

  To check that if ASCONF chunk is received bundled with other chunk as the first
  chunk then the endpoint should accept both of the messages and response ASCONF
  chunk with ASCONF-ACK chunk.

SYNOPSIS

  ./BundledAsconfAndOther.seq [-tooloption ...] -pkt ./BundledAsconfAndOther.def
    -tooloption : v6eval tool option

            ../common/SCTP_COMMON.def

PRE-TEST CONDITION

  Association is established between endpoint A and B. Arrange the date
  in endpoint A such that ASCONF chunk which is bundled with other chunk
  as the first chunk is sent to endpoint B.

TEST PROCEDURE

  Endpoint A                           Endpoint B                ULP
  (ESTABLISHED)                        (ESTABLISHED)

  ASCONF + DATA ----------------->

                <-----------------      ASCONF-ACK + SACK

  TEST DESCRIPTION:

  1. Send ASCONF chunk bundled with other chunk as the first chunk
     from endpoint A to B.
  2. Check A: ASCONF-ACK chunk should be received to response the
     ASCONF chunk at endpoint A.

NOTE

  None

  RFC 5061

  5.1.1.  Congestion Control of ASCONF Chunks

    In defining the ASCONF Chunk transfer procedures, it is essential
    that these transfers MUST NOT cause congestion within the network.
    To achieve this, we place these restrictions on the transfer of
    ASCONF Chunks:

    C2)  An ASCONF Chunk may be bundled with any other chunk type
         including other ASCONF Chunks.  If bundled with other ASCONF
         Chunks, the chunks MUST appear in sequential order with respect
         to their Sequence Number.

    C3)  An ASCONF-ACK Chunk may be bundled with any other chunk type
         including other ASCONF-ACK Chunks.  If bundled with other
         ASCONF-ACK Chunks, the chunks MUST appear in sequential order
         with respect to their Sequence Number.
