c*********t 发帖数: 2921 | 1 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 | 2 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.
usage,

而且,知道的人多。你自己写个simulator,发文章,人家还会问你为啥不用ns2哪
