Case 2 Broadcasting the Olympic Games The Management of the WBO television network has been celebrating for days. What a coup! After several unsuccessful attempts in recent decades, they nally have hit the big jackpot. They have won the bidding war to gain the rights to broadcast the next Summer Olympic Games! The price was enormous. However, the advertising income also will be huge. Even if the network loses some money in the process, the gain in the prestige should make it worthwhile. After all, the entire world follows the games closely every four years. Now the entire world receiving the feed of the broadcast from the WHO Network will learn what a preeminent network it is. However. reality also is setting in for WBO management. Telecasting the entire Olympic games will be an enormously complex task. Many different sporting events will be occurring simultaneously in farflung venues. An unprecedented amount of live television and live-on internet coverage of the various sporting events need to be planned. Due to the high amount of bandwidth that will be required to transmit the coverage of the games back to its home studios, WBC needs to upgrade its computer network. It operates a private computer network as shown in the network diagram. T {Q _''__ __'' K ' 15 HIE/'31 x it. 1. t .a he " /' ,_.--' . as x Q.- 't a" X 't. 9 I'. " ". ' "I II 'll'g H~H I . at: '. / .
