 Connection keep-alive # A Waku v2 client MAY choose to implement a keep-alive mechanism to certain peers. If a client chooses to implement keep-alive on a connection, it SHOULD do so by sending periodic libp2p pings as per 10/WAKU2 client recommendations. The recommended period between pings SHOULD be at most 50% of the shortest idle connection timeout for the specific client and transport. For example, idle TCP connections often times out after 10 to 15 minutes.
 Implementation note: the nim-waku client currently implements a keep-alive mechanism every 5 minutes, in response to a TCP connection timeout of 10 minutes.
