SSD8的练习2 希望能帮助大家 参考学习

Answers to questions in Part 2:

1.I did the job on my comprter,the destination is www.baidu.com,
the result is as follow:

C:\Documents and Settings\Administrator>tracert www.baidu.com

Tracing route to www.a.shifen.com [220.181.6.6]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  192.168.0.1
  2    10 ms     9 ms     9 ms  202.103.29.38
  3     8 ms    10 ms    10 ms  221.232.255.205
  4    10 ms     9 ms     7 ms  221.232.254.101
  5     5 ms     4 ms     5 ms  221.232.254.233
  6    29 ms    30 ms    25 ms  202.97.34.165
  7    33 ms    36 ms    30 ms  220.181.16.149
  8    45 ms    34 ms    45 ms  220.181.16.14
  9   242 ms   239 ms   237 ms  220.181.17.150
 10   252 ms   244 ms   246 ms  220.181.6.6


From the above,we can see that the 10th hop on the path is the longest.


2.I use the ping utility to verify two of these roundtrip times.

  (1)The ping result of the 4th hop:

C:\Documents and Settings\Administrator>ping 221.232.254.101

Pinging 221.232.254.101 with 32 bytes of data:

Reply from 221.232.254.101: bytes=32 time=11ms TTL=252
Reply from 221.232.254.101: bytes=32 time=11ms TTL=252
Reply from 221.232.254.101: bytes=32 time=3ms TTL=252
Reply from 221.232.254.101: bytes=32 time=3ms TTL=252

Ping statistics for 221.232.254.101:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 11ms, Average = 7ms

(2)The ping result of the 10the hop:

C:\Documents and Settings\Administrator>ping 220.181.6.6

Pinging 220.181.6.6 with 32 bytes of data:

Reply from 220.181.6.6: bytes=32 time=255ms TTL=52
Reply from 220.181.6.6: bytes=32 time=247ms TTL=52
Reply from 220.181.6.6: bytes=32 time=248ms TTL=52
Reply from 220.181.6.6: bytes=32 time=250ms TTL=52

Ping statistics for 220.181.6.6:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 247ms, Maximum = 255ms, Average = 250ms

We can see that the two roundtrip times are almost the same.
