image stream routers

Sat Sep 17 01:09:42 UTC 2005

I'd be interested to know the relative pros and cons of switching packets in
software (Imagestream) versus handing them off to a dedicated ASIC (Cisco,
Juniper)

Had a discussion with the manager of a large ISP in Turkey. He's a 
transplanted Aussie.. He swears by them.. I believe he is running OC-12
links accross them at near full capacity.

My personal experience has been that they have both the engineering talent 
and the experience (7+ years in the business) to pull it off. Their 
products are logically built, utilize Linux at the core and they stand 
behind their gurantee. If it doesn't work, they'll either fix it, or give 
you your money back.

They are now keepers and developers of the VRRP project for Linux, and 
have also defined a unified driver architecture called "Inetics" which 
makes adding new hardware to Linux trivial.

I'm going to be attending a presentation by one of their core developers 
at the Ohio Linuxfest on October 1st (http://www.ohiolinux.org). From the 
website, here is the specific talk they will be giving:

"Quality of Service using Open Source Linux Tools
Doug Hass, Imagestream

With increasing penetration of wireless and broadband, service providers 
must understand Quality of Service techniques and implement QOS on their 
networks. A proper QOS design helps to avoid network bottlenecks caused by 
converged voice/video/data services , broadband users, file sharing, and 
other bandwidth-intensive applications. Without QOS, service providers are 
especially susceptible to bottlenecks and service degradation.

This presentation covers the key concepts of quality of service. The 
presentation includes an explanation of standard queuing methods as 
defined in the Differentiated Services RFC as well as applications of 
these methods through generic case studies. 

Doug Hass is the COO of ImageStream, a leading router and WAN product 
manufacturer. Prior to joining ImageStream, Mr. Hass was a partner in 
Midwest-based Internet provider Skye/net. An Army veteran, certified 
personal trainer, avid horseman and outdoorsman, Mr. Hass rode 
professional rodeo for five years, and is the founder of Roughstock.com, 
an award-winning country music Web site."
