Re: [Ibnemo] [Nfvrg] 答复: 答复: Defining a Common Model for intent

["Gember-Jacobson, Aaron" <[e-mail]>]

Flowlog is a "network SQL" for SDN (
https://www.usenix.org/conference/nsdi14/technical-sessions/presentation/nelson).
There's also NDlog (
http://www.cis.upenn.edu/~boonloo/papers/declarenet_cacm09.pdf). However, I
think the level of abstraction provided by both Flowlog and NDlog is lower
on the policy continuum than many expressions of intent. Nonetheless, these
works may be a valuable starting point for a declarative language for
intent.
