Strictly speaking， after failover, we only need to keep servicing for the tcp connections which are established after the last checkpoint but not all existing connections. Because after a checkpoint （primary and secondary node works well）, primary vm and secondary vm is same， that means the existing tcp connection has the same sequence。
