Re: [Bloat] Network test tools for many parallel/concurrent connections?

[Isaac Konikoff <konikofi@candelatech.com>]

Candela makes a Linux based network traffic test tool called 
LANforge-FIRE. It can generate in excess of 50,000 TCP connections among 
other features. It is a proprietary tool, but we'll send out free 
licenses to students and those working on non-commercial open source 
projects.

Thanks,
Isaac
