- There are two perspectives to consider. It is assumed that the most recent SampleRTT on a TCP connection is 1 second. To keep the current connection open, TimeoutInterval has to be larger than or equal to one second.arrow_forward199arrow_forwardAssume that a bottleneck connection with a rate of R bps carries two TCP connections. In both cases, there is a big file that must be downloaded (in the same direction over the bottleneck link). The files are all transmitted at the same time How much data will TCP be able to transmit each connection?arrow_forward
- Is it the case or not? Let's pretend the most recent SampleRTT on your TCP connection was 1 second. The connection will time out if the TimeoutInterval is less than one second.arrow_forwardIs this an accurate or wrong statement? For simplicity, let us assume that the most recent SampleRTT on a TCP connection is one second. The current TimeoutInterval value for the connection must be greater than one second in order to maintain the connection.arrow_forwardIs this statement true or false? Let's say for the sake of simplicity that a TCP connection's most recent SampleRTT is one second. The connection must be kept open if the current TimeoutInterval value is larger than one second.arrow_forward
- Is this correct or incorrect? Assume that on a TCP connection, the most recent SampleRTT is 1 second. The current TimeoutInterval value for the connection must be larger than one second.arrow_forwardCan you confirm or deny that this is the case? Assume that the most recent SampleRTT on a TCP connection is 1 second. It's not possible to have a connection with a TimeoutInterval less than one second.arrow_forwardThere are two ways to look at it. Assume that the most recent SampleRTT on a TCP connection is 1 second. TimeoutInterval must be greater than or equal to one second for the current connection.arrow_forward
- Is this statement true or false? Let's say for the sake of simplicity that a TCP connection's most recent SampleRTT is one second. The connection must be kept open if the current TimeoutInterval value is larger than one second.arrow_forwardConsider the TCP procedure for estimating RTT. Suppose that α=0.1. Let Sample RTT1, be the most recent sample RTT, let Sample RTT2 be the next most recent sample RTT, and so on.a. For a given TCP connection, suppose four unacknowledged have been returned with corresponding sample RTTs, SampleRTT4, Sample RTT3, SampleRTT2, and SampleRTT1. Express EstimatedRTT1 in terms of the four sample RTTs.b. Generalize your formula for n sample round-trip times.arrow_forwardThere are two perspectives to consider. It is assumed that the most recent SampleRTT on a TCP connection is 1 second. To keep the current connection open, TimeoutInterval has to be larger than or equal to one second.arrow_forward
