Suppose that the maximum transmit window size for a TCP connection is ...
In slow-start phase, for each ACK, the sender increases the current transmit window by Maximum Segment Size (MSS). In
the question it is given a packet consists of 2000 bytes and that can be taken as MSS. So, after two ACKs, current transmit
window
= 4000 + 2000 + 2000
= 8000
the question it is given a packet consists of 2000 bytes and that can be taken as MSS. So, after two ACKs, current transmit
window
= 4000 + 2000 + 2000
= 8000

Suppose that the maximum transmit window size for a TCP connection is ...
Given:
- Maximum transmit window size for a TCP connection: 12000 bytes
- Each packet size: 2000 bytes
- Current transmit window size in slow-start phase: 4000 bytes
- Two acknowledgements received
To find:
Maximum possible value of the current transmit window
Explanation:
In TCP's slow-start phase, the transmit window size increases exponentially for every acknowledgement received until it reaches a congestion threshold. After that, it enters the congestion avoidance phase where the transmit window size increases linearly for every acknowledgement. Since no packets are lost and there are no timeouts, we can assume that the congestion threshold has not been reached.
Slow-start Phase:
- In the slow-start phase, the transmit window size doubles for every acknowledgement received.
- Initially, the current transmit window size is 4000 bytes.
- After the first acknowledgement, the transmit window size doubles to 8000 bytes.
- After the second acknowledgement, the transmit window size doubles again to 16000 bytes.
Congestion Avoidance Phase:
Since the transmit window size has exceeded the maximum transmit window size of 12000 bytes, it enters the congestion avoidance phase. In this phase, the transmit window size increases linearly for every acknowledgement received.
Maximum Possible Value of Current Transmit Window:
Since the maximum transmit window size is 12000 bytes, the maximum possible value of the current transmit window is limited to this size. Therefore, the maximum possible value of the current transmit window is 12000 bytes.
Conclusion:
The maximum possible value of the current transmit window is 12000 bytes, which is option 'B'.
