Re: [I2nsf] Request for Comments on I2NSF Security Policy Translation

["Mr. Jaehoon Paul Jeong" <[e-mail]>]

Hi Diego,
in our I2NSF security policy translator, a restconf xml file based on a
high-level policy YANG is translated into a netconf xml file based on a
low-level policy YANG.

RFC 8106 is an example to show that the implementation considerations are
useful to developers though RFC 8106 is about IPv6 DNS autoconfiguration.

Without our I2NSF security translation draft, it is hard for developers to
figure out the implementation of Security Controller that bridges
Consumer-Facing Interface and NSF-Facing Interface.

Thanks.

Paul
