For showing RED solves global synchronization problem,bias againt bursty traffic, i tried a lot using tcl script making different scenarios. But no useful results at all. In my case packet loss is more in RED than DropTail. somenone please help From jwbensley at gmail.com Sat Jan 3 12:22:07 2015 From: jwbensley at gmail.com (James Bensley) Date: Sat, 3 Jan 2015 21:22:07 +0100 Subject: [e2e] RED vs DropTail using NS2 In-Reply-To: References: Message-ID: Hi, Can you share the testing you performed with NS2 and via TCL, maybe someone can suggest and improvement to your method.

For this sort of experiment, Mininet offers more easier and accurate benchmark environments than NS2 (or 3). More, check this out http://reproducingnetworkresearch.wordpress.com/2012/06/05/seeing-red/ This Mininet experiment considering RED and DropTail report may give you some points.

For sure i will try with these scripts.May b i can get some useful results . Thanks a lot.
