Consider a $TCP$ connection which starts with initial congestion window equal to $2\ast \text{MSS}$ where the maximum segment size $\text{(MSS)}$ is $1460$ bytes. Suppose that initially two packets are sent out, each of size $\text{MSS}$, and $\text{ACKs}$ corresponding to both are received by the sender. Assuming that $\text{TCP}$ is still in slow start, the congestion window after receiving the second $\text{ACK}$ is: _____
