Hi John,

if you do not explicitly bind addresses, all addresses
will be used. Thus you use the multihoming features
as son as you are multihomed.

Please note that you get an notification that a path
status has changed. If the application choses a
the primary path if the old one is not reachable
anymore or if this is done by the SCTP implementation
is implementation dependent. But in any case SCTP
will make sure that the data will be delivered to the
peer.

Best regards
Michael

I'm about to start using the multihoming features
using the socketapi and need to understand the
following points.

1. If I pull out the IP cable connected to my primary
address, will the local SCTP detect the failure and
automatically pick a new address to be the primary
(and send me a Notification - SCTP_ADDR_MADE_PRIM)? Or
will I receive a SCTP_SEND_FAILED, and it be up to my
application to select a new primary?

2. Is there an example c code application which uses
multihoming and socketapi?

I'm hoping to be able to detect failure and change to
another primary address without any loss of data, or
having to put any queues in my application.

Regards,

John.
