Consider the latency model for static congestion windows. If the server receives an acknowledgement for the first data segment i

n the first window before the server completes the transmission of the first window, then the latency for an object of size O is:

Answer:

Latency of an object O is shown below.

Explanation:

W segment and stalled state transmits nothing and waits for acknowledgement. The latency is 2 R TT + the time required for server that are using to transmit the object + the amount of time when server is in stalled state. Let K be the number of window that is K= O/WS .The serveries stalled state where K-1 is period of ime with period lasting RTT-(W-1)S/R

latency = 2RTT +O/R +(K-1)[S/R +RTT - WS/R]

After combining the two case

latency = 2 RTT + O/R + (K-1)[S/R +RTT - WS/R]

where [x] means maximum of (x.0). This is the complete ananlysis of the static windows.

server time for transmit the object is (K-1)[S/R +RTT - WS/R]
