Detailed Description

Ping packet: Sent to check if node is alive.

PingNode is cached and regenerated after ts + t, where t is timeout.

Ping is used to implement evict. When a new node is seen for a given bucket which is full, the least-responsive node is pinged. If the pinged node doesn't respond, then it is removed and the new node is inserted.
