I encountered a strange question, that this file cannot be exported by
org-mode's HTML exporter, which just return "Wrong type argument:
stringp nil". But I cannot find out where the point is. (And, all the
other files can be outputed without any question.)
I attached this file for reproducing issue.
* 第一部份
** What is the IP address and TCP port number used by the client computer
(source) that is transferring the file to gaia.cs.umass.edu?
#+BEGIN_QUOTE
To answer this question, it ’ s probably easiest to select an HTTP message and
explore the details of the TCP packet used to carry this HTTP message, using
the “ details of the selected packet header window ” (refer to Figure 2 in the
“ Getting Started with Wireshark ” Lab if you ’ re uncertain about the
Wireshark windows.

** What is the sequence number of the TCP SYN segment that is used to initiate

it in the segment that identifies the segment as a SYN segment?
TCP SYN 的 SeqNum 為 0；上面寫著[SYN, ACK]。

我不確定題目問的是哪一個[fn:2]， *因為 No. 168 也有包含 "POST" 一詞（sequence number 是 152050）*
，原本以為題目提到的"the TCP segment containing the HTTP POST"就是這個，但：
1. *Wireshark 在顯示 No.168 時，螢幕最下方多了一個* =Reassembled TCP= *的分頁* 。
2. 而且封包 No. 168 在 Wireshark 裡雖然可以看到整個上傳的 txt 檔完整內容，然而 No.168 這個 *封包本身的的 length
似乎卻只有 973* 。
3. 接在 No. 168 後面出現的封包只剩下一堆 ACK 和最後一個 HTTP 200，而沒有任何實際在「上傳 txt 檔案」的封包。
所以 No. 168 只是 *整個 POST 都結束了才出現的最後一個封包* 、用來告訴對方「我剛剛傳的『第#14,
#15,#16.......個封包』是要接在一起的」這樣嗎？
我不太確定自己有沒有搞錯，以下為 wireshark 中，No. 168 的 TCP 欄位顯示的東西：

throttle the sender?
1. 第一個問題救命啊不知道該從哪裡看。[fn:1]
2. 第二個問題是：沒有，因為資料傳輸過程中封包長度一直都是 1470 沒有因為 buffer 被塞爆而縮小過。[fn:3]
*** Are there any retransmitted segments in the trace file? What did you check
for (in the trace) in order to answer this question?
沒有，因為 wireshark 吐出來的整串封包清單都沒有重複的 ACK num。
*** How much data does the receiver typically acknowledge in an ACK? Can you
identify cases where the receiver is ACKing every other received segment (see
Table 3.2 on page 257 in the text).
1. 1460。
2. 我看不懂這題指的"*every other* received segment"到底在說什麼。[fn:6]
*** What is the throughput (bytes transferred per unit time) for the TCP
connection? Explain how you calculated this value.
97842.160 bytes/sec；直接看 Wireshark: Statictics => Summary => Avg.
bytes/sec（算作弊嗎？）
整個 dump 出來的檔案大小 175184 bytes；從 SYN 開始直到收到最後一個 ACK 共歷時 1.716571 秒
175184 / 1.716571 = 102054.619355 #呃...我不太確定該怎麼算，不過跟上面的值好像蠻接近的。

** Use the Time-Sequence-Graph(Stevens) plotting tool to view the sequence
number versus time plot of segments being sent from the client to the

the measured data differs from the idealized behavior of TCP that we've studied
