SCTP Issues
Flows are (often) acknowledged (almost) immediately increasing significantly the network traffic. This amplifies problems in some situations (e.g. in case of DoS attacks).






SCTP is supported only on a few platforms and there are no plans to support it in Windows or network equipment. This could limit the usage of IPFIX at least in its early days.
Unclear how reliable/robust is SCTP and how it behaves in production environments (network attacks?).
