Question: Each packet has 8 0 0 0 bits, the link speed is 1 Gbps and the propagation delay is 1 5 ms each way. ACKs

Each packet has 8000 bits, the link speed is 1Gbps and the propagation delay is 15 ms each way. ACKs are send whenever a packet arrives and the ACKs are small, so that the transmission time of an ACK can be ignored.
How big would the window size have to be for the channel utilization to be greater than 98 percent? That is, how big would the window need to be so that packets are being transmitted 98% of the time.
Each packet has 8 0 0 0 bits, the link speed is 1
