Which of the following would require a TCP connection over UDP for a reliable data transfer? (Choose all that apply.)
| a. |
a Skype connection |
|
| b. |
|
|
| c. |
Streaming video at YouTube |
|
| d. |
file transfer |
Homework Answers
Answer is as follows :
For given scenario Skype connection is more reliable on UDP because it is fast delivering packets, so quality for video calling get good.
For Email, we know that SMTP i.e. Simple mail transfer protocol is used that is part of TCP. But UDP in this case is less reliable as compare to TCP, because TCP handle these type of data efficiently.
Streaming Video at you tube, currently UDP is used, but for buffering issues TCP is more reliable.
File transfer is more reliable in TCP rather than UDP, because it is based on FTP i.e. mostly used under TCP.
So correct answer are :
b. Email
c. Streaming video on YouTube
d. File Transfer

You are designing a reliable byte stream transport layer protocol (not TCP) to operate over a 1x107 bps network and it is using a sliding window for flow control. The time for keeping the transmission pipe full is taken to be the RTT of the network which is 50ms. Each number in the advertised window or sequence number represents 2 bytes of data. a) What is the minimum number of bits necessary for the Advertised Window field of your protocol...
