What else can I help you with?
If the tcp round trip time rtt is currently 30 msec and the following acknowledgements come in after 26 32 and 24 msec respectively what is the new rtt estimate using the jacobson algorithm use a0.9?
RTT = alpha * RTT + (1-alpha)*M RTT = 30 RTT = 0.9 * 30 + 0.1 * 26 = 29.6 RTT = 0.9 * 29.6 + 0.1 * 32 = 29.84 RTT = 0.9 * 29.84 + 0.1 * 24 = 29.256 hope it's right
Calculate estimated RTT DevRTT timeout interval?
To calculate the estimated Round-Trip Time (RTT) and the DevRTT (deviation of RTT), you can use the following formulas: Estimated RTT: ( \text{Estimated RTT} = (1 - \alpha) \times \text{Estimated RTT} + \alpha \times \text{Sample RTT} ), where ( \alpha ) is typically set to 0.125. DevRTT: ( \text{DevRTT} = (1 - \beta) \times \text{DevRTT} + \beta \times |\text{Sample RTT} - \text{Estimated RTT}| ), where ( \beta ) is generally set to 0.25. Timeout interval: ( \text{Timeout} = \text{Estimated RTT} + 4 \times \text{DevRTT} ). Using these formulas with appropriate RTT samples will give you the estimated RTT, DevRTT, and the timeout interval.
What is Tcp time stamp?
TCP timestamp is an option in the Transmission Control Protocol that allows for the inclusion of a timestamp in TCP segments. This feature helps in measuring round-trip time (RTT) and managing the sequence of packets more effectively, enhancing the efficiency of data transmission. By providing the sender and receiver with the ability to track the timing of packets, TCP timestamps can also help prevent issues like sequence number wraparound in long-lived connections. Overall, it improves the performance and reliability of TCP connections.
Is it possible for TCP Reno to reach a state with the congestion window size much larger than (e.g. twice as large as) RTT bandwidth?
Yes, it is possible for TCP Reno to reach a state where the congestion window (cwnd) size is much larger than twice the round-trip time (RTT) bandwidth. This can occur during the additive increase phase, where TCP Reno increases cwnd by one segment for each round-trip time, potentially allowing it to exceed the bandwidth-delay product under certain network conditions. However, this situation can lead to congestion and packet loss, triggering the congestion control mechanisms that will subsequently reduce the cwnd. Therefore, while it can temporarily exceed this threshold, it is not sustainable without causing network issues.

What is full-form RTT?
RTT stands for Round-Trip Time. It is a network performance metric that measures the time it takes for a data packet to travel from the source to a destination and back again. RTT is crucial for assessing latency in network communication and can impact the performance of applications, especially those requiring real-time data transmission.
