Question

Explain how you calculated the values

Explanation / Answer

The least RTT can be calculated as follows: 2 * (Shortestpath from switch-1 to outside) / speed of light                                                             = 2 * (switch1--> switch2)/ speed oflight                                                             = 2 * (5+7) * 103 / (3 *108) [assuming the distances given inKms]                                                                              = 8 *10-5seconds                                                            = 80 microseconds The greatest RTT can be calculates as follows: 2 * (largestpath from switch-1 to outside)/ speed of light                                       = 2* (switch-1--> R1--> R2-->R4-->R6-->R9->R8-->R7-->switch-4)/speed oflight                                                  = 2 * (5 + 6 + 23 + 19+ 17 + 12 + 11+ 19) * 103 /(3* 108)                                          =112/3 *10-5                                          =373.33 microseconds
