* Tail Latency
200ms latency -> initial rto by most OSs
Do not consider normal Retransmissions, but only RTOs
exponential backoff rto will double with each iteration -> 400ms, 800ms, 1000ms
congestion, pathmtu not honored, icmp rate-limited, reply pathmtud-reply packets dropped,
os issues -> Zero window -> cpu high(response slow), memory high, disk issue
