Hi,

Trying to finally finish my AD review of the SCTP NAT I did find that this document does not appear to define what a "Control Chunk" is. As it is relevant for what one may bundle, and how placement is etc it would be good to be explicit about what it is.

Cheers

Magnus Westerlund

> Abstract:
>    This document obsoletes RFC 4960, if approved.  It describes the
>    Stream Control Transmission Protocol (SCTP).  SCTP is designed to
>    transport Public Switched Telephone Network (PSTN) signaling messages
>    over IP networks, but is capable of broader applications.
> 
>    SCTP is a reliable transport protocol operating on top of a
>    connectionless packet network such as IP.  It offers the following
>    services to its users:
> 
>    *  acknowledged error-free non-duplicated transfer of user data,
> 
>    *  data fragmentation to conform to discovered path maximum
>       transmission unit (PMTU) size,
> 
>    *  sequenced delivery of user messages within multiple streams, with
>       an option for order-of-arrival delivery of individual user
>       messages,
> 
>    *  optional bundling of multiple user messages into a single SCTP
>       packet, and
> 
>    *  network-level fault tolerance through supporting of multi-homing
>       at either or both ends of an association.
> 
>    The design of SCTP includes appropriate congestion avoidance behavior
>    and resistance to flooding and masquerade attacks.
