I think the multi-homing feature of SCTP is not so useful. It adds a layer of complexity without so much gain.What do you think of it.

1) It makes the SCTP header complex. Without it, IP address in IP header is sufficient. With it, IP addresses have to appear in SCTP header too.

2) Multi-homing makes it difficult to configure firewall rules, for example NAT(Network Address Translation). Linux tools like iptables, LVS(Linux Virtual Server) do not work well with it.

3) I think the benefit of multi-homing can be gained in Network-layer or Data-Link layer instead of transport layer, for example network interface bonding, etc. It relieves the complexity of the application in this way.

I must iterate:" I’m taking a 3000-foot perspective here, it is still a far away perspective although less a 0 than the author, and whatever I’m writing could be completely wrong. If that’s the case, please point out my mistakes in your comments."
