Re: Multi-NIC support to Cactus


Hello Ewan,

Thanks for your answer. Now it's clear to me.

Network model topic is big issue and multi-nic issue is also not a small issue if we cover "any" network topologies. I'm expecting at first thought - 
1. instances can have more than 2 vifs.
2. cloud user can decide how many vifs instance have.
3. different vlan can be assigned to vifs.
4. different security groups can be assigned to vifs.
5. "vifs are assigned which physical nics" kind of thought is necessary(?)
Those are just first shallow thought - things can go step by step.

I personally feel that not only model-basis discussion but also functionality-based discussion may be good to accelerate better network model..

Kindly Regards, 
Kei Masumoto

That's a good question.  Multi-NIC support could be separated out from the rest of the network-service blueprint, but I don't know whether it would be useful to do so.

I assume that the tenant will not be able to configure any rich network topologies until network-service is done.  If that is true, what else would you do with multi-NIC support?  And how do you imagine that it would work?
