c****d 发帖数: 116 | 1 I read a paper on fat tree, and fat pyramid in parallel
computing area. At the end of the paper, it used
NS2 to simulate the performance like throughput, delay
stuff. I know NS2, but not sure if it is valid to be
used for verify the proposed schemes/algors in different
area. Thank you. |

w*******e 发帖数: 285 | 2 不知道大家用ns2多不多,我们lab最近买了一台机器装redhat enterpirse
linux 4 64bits version.然后安装ns2,结果otcl装不上去,configure的结果是
checking build system type... 2Invalid configuration `x86_64-unknown-linux-gnu
': machine `x86_64-unknown' not recognized
configure: error: /bin/sh ./config.sub x86_64-unknown-linux-gnu failed
这个是不是跟64位有关呢?我google了半天也不太行,大家有谁有过类似经验阿,
江户救急啊。 |

How to get the average packets delay time for UDP?

z*****n 发帖数: 7639 | 5 rxthresh 指的是接收灵敏度阀值。如果这个参数改小,
说明灵敏度变高,接收机可以收到更微弱的信号。
transmission range in NS2 can be controlled by
both txpower and rxthresh. The signal propagation
model by default is set as 2-way ground. So once
the txpower and rxthreshold are set, the range is
determined. |

w******u 发帖数: 219 | 8 请教版上各位大牛,
我在投稿一个journal的时候,审稿意见其中有一条是"the authors do not justify
their
choice to use the OPNET simulator to validate their technique. Does it
offer features not implemented in more common simulators, such as ns2 or
Omnet++?"
我用OPNET写仿真主要是因为实验室有LICENSE,而且有用OPNET仿真的传统。别的原因
还真不知道,
请问这个我怎么写好? |

Interesting thing is that you ask my research, which almost has no relation

failed on the following questions.
Q: why did you write your simulator instead of using opnet, and ns2 or...(

A: first I use ns2, but I found bugs, but it is difficult to find all bugs."
For opnet, I cannot get it free.

c*********t 发帖数: 2921 | 11 是不是NS2很适合packet level的仿真?比如可以创建topology, 然后看traffic (如
TCP, or UDP)的packet 的loss, delay。这种是很微观的simulation.
如果想做很宏观的simulation比如在flow level, 比如只关心link capacity 的usage,
available bandwidth, 多少个不同的connections, 网络上traffic的动态的情形(一
些new flow come, 一些old flow finish),或者是动态的topology(some links are
up, and some links are down), 能用Ns2 来做这方面的simulation吗?
好像很多人自己写discrete event driven simulation来仿真。
谁有好的建议。谢谢! |

d****i 发帖数: 1038 | 13 sure you can. but don't ask me how. I was an OPNET modeler user.
only know a little of ns2. but I know it can.
you have to add/modify some code in ns2 to calculate/simulate whatever you
want to do. It will be easier and more trustworthy than you write from
scratch.

hostmonster.com. Note that it can take 4 - 48 hours for propagation.
这个是DNS (domain name system), 你在他们网页上找找link(要等你log in
Cpanel才行),把它们update成ns1.hostmonster.com and ns2.hostmonster.com 然后
可能要等4-48hours,才会transfer完成啊。简单讲就是这样了。
嗯我以前自己家里host自己的网页和email服务器的。还记得大致怎么弄。现在host在
外面,比自己家里run个server还便宜。电费也是费。 |
