TCP keep-alives aren't reliably implemented.
I've got reports that sometimes we struggle to keep connection to the
network on mobile, eg, because we roam into an area with poor
connectivity but not poor enough for the network stack to drop access
entirely. Being able to quickly check if the connec

https://github.com/bitcoin/bitcoin/pull/932 adds a "pong" message that
echoes back a 64 bit nonce contained in the ping, if the protocol
version is new enough.
The goal of this is to make it easier for clients, especially mobile
clients, to quickly check if a connection is stale, and also to see i

They can't always judge it, eg if the link between you and that peer

I haven't written a patch for this, I might do so if there's
sufficient interest.
Nodes that are under heavy load exhibit extremely high latency, this
makes downloading the block chain from a node that is itself
downloading the block chain basically useless as it takes 30-60
seconds for the node t
