const (
	PeerConnectionTimeoutMax = 45000 // ms
	PeerConnectionTimeoutMin = 30000 // ms
)

PeerConnectionTimeoutMax is a timeout of an initial connection attempt to a remote peer. E.g. this peer will wait PeerConnectionTimeoutMax for the remote peer to respond, if not successful then it will retry the connection attempt. Todo pass timeout at EnginConfig
