Ben Bitdiddle, an astronomer at UC Davis, produces 400 terabytes (assume 400 trillion bytes) of data daily. He needs to send the data to his colleague Alyssa at Stanford. Ben has three assistants who each propose a different way to get the data to Alyssa as quickly as possible. On all parts of this problem. clearly state your assumptions. Your instructor computed band- widths in bits per second, so you should too.
(a) Cy proposes to send the data through the Internet. He realizes that he can have exclusive use of UC Davis's CENIC 100G connection to send the data to Alyssa. (As with all parts of this problem, you will have to do some searching to figure out various speeds, sizes, etc.) What is Cy's bandwidth (bits/s)? How long does it take the first bit of data to arrive (latency)? How long does it take him to send all the data to Alyssa?
(b) Eva has a number of friends with wireless hubs on the route from Davis to Stanford running the new 802.11ax (Wi-Fi 6) wireless protocol. She can send data from friend to friend until it reaches Alyssa, all using 802.11ax connections, all running at peak 802.11ax bandwidth. What is Eva's bandwidth? How long does it take the first bit of data to arrive (latency)? How long does it take her to send all the data to Alyssa?
