[ECOS] ZeroConf (Avahi, Bonjour) and the need for Multiple IPs

[ECOS] ZeroConf (Avahi, Bonjour) and the need for Multiple IPs

[Paul McHale]

Hi,

We are considering implementing ZeroConf like functionality under eCos.  To
do this, we must support participating in the ZeroConf predertimined subnet. 
This alone is simple enough provided there is support for multicasting and
we only wanted to participate in the ZeroConf subnet.

The problem we have is also participating in our customers non-ZeroConf
subnet simultaneously.  For Linux and Windows this is not a problem as more
than one IP can be supported by a single network device.  Is this possible
in eCos?  I would appreciate any recomendations regarding multiple IPs and
multicast support.

For those not familiar with ZeroConf:

Excellent YouTube video from the folks at Google 

If you develop Ethernet products, you owe it to yourself to check out the
youtube video :)

Kind Regards,
Paul

the IP stack in eCos is from FreeBSD from maybe 5 years ago. Take a
look at how you do multiple IP addresses on an interface on an old
FreeBSD system. Probably the same is true for eCos.
