Hi Robert,
If shutting down the link or lc requires some central management station it
does change the full design (perhaps simplifies it vastly) where all of the
optimizations can be centrally managed perhaps to varying degrees.
Shutting down a link does not require centralized management action. It is
quite sufficient to coordinate it between the routers on the ends of the link.
Note that one can also conceive of a situation where there is a unilateral,
ungraceful shutdown too. That requires zero coordination.
I'm curious about these new power-sleep modes.
- Are these offered for single laser or single links or is it more of using
only a few links in a bundle of links (LAG)?
- If single laser or single link, what's might a transition time for an
interface to go from power-sleep to fully-functional/bandwidth-capable look
like -- i.e., is it faster than going from shut to no shut on a typical laser?
- What might typical power savings (%) look like when we put an interface into
power sleep mode?
- What does power sleep bandwidth look like (maybe % wise)?
Thanks!
Chris.
