What's the kademlia peer expire strategy in kbucket?

[lynic]

I'm trying out kademlia, and start/stop some random peers. Trying to understand how does kademlia routing table work, I have couple of questions:

• Once a peer's status is disconnected, how long will it be removed from kbuckets/routing table?
• Will a disconnected peer be advise to another peer's routing table?
• I found that even though the peer is destroyed, get_provider will still return this peer id.

* Once a peer's status is disconnected, how long will it be removed from kbuckets/routing table?

It will be removed once we have a better peer available to replace the former.

* Will a disconnected peer be advise to another peer's routing table?

Yes. If I recall correctly.

* I found that even though the peer is destroyed, get_provider will still return this peer id.

See above.

Hope this is of some help.
