Re: Network Service for L2/L3 Network Infrastructure blueprint

 

Hello Hisaharu san

I am not sure about the differences between generic network API and
plugin X specific network service API.

Do you mean that the former API is an interface that is
defined in OpenStack project, and the latter API is 
a vendor specific API?

Thanks
Hiroshi
