What are the outlines to achieve at least a ceasefire in Ukraine?

 I want this war turned off.

If not for the sake of Ukrainian/Russian soldiers then for the greater good world wide.

I contend that this war has had unintended knock-on effects that are damaging to the world economy, the food security of possibly billions and is pushing to destabilize Europe.

So what would the outlines of a ceasefire look like.  Note I said ceasefire, not a peace treaty.  Baby steps for this emotionally charged issue.

Personally I think that the lines should be frozen.  Then a buffer zone established between the two sides monitored by a quartet that includes the US/EU, China, the UN (unaligned nations) and India/certain African states.  

Why this grouping?  Because the sanctions have in essence made the whole world take sides.  With this grouping we have the most powerful nations on the planet (the US & China) participating, the EU which has aligned with the US and is nearest the fight involved, the UN with the unaligned nations (is there really such a thing with the way this thing has been setup) acting as a "neutral" force and India/certain African states to act as a counter to the probable view of Russia/China that the EU added to the US body gives it an unreasonable weight on the scales.

No troops on the ground but electronic monitoring by ground sensors and aerial vehicles (big and small uavs) would keep both sides honest.

The ceasefire would be the first step towards working towards a peace treaty that would finally end this insanity.

Note that any fantasy of Ukraine pushing Russia back is just that. At this point it would take the full involvement of NATO to retake all of Ukraine and even with that the body count would be horrendous and be a certain gift to the Chinese who would stroll into Taiwan with ease because the West, most especially the US would turn on foreign wars in a way that made the Vietnam malaise look like pleasant.

What say you.
