If you can read French and if you are interested in networking technologies, then you must read Stephane Bortzmeyer’s blog – interesting stuff in every single article. Needless to say I’m a fan.
Stéphane commented an article by Nokia people : « An Experimental Study of Home Gateway Characteristics » – it exposes the results of networking performance tests on 34 residential Internet access CPE. For a condensed and more clearly illustrated version, you’ll appreciate the slides of « An Experimental Study of Home Gateway Characteristics » presented at the IETF 78’th meeting.
The study shows bad performance and murky non-compliance issues on every device tested. The whole thing was not really surprising, but it still sounded rather depressing to me.
But my knowledge of those devices is mostly from the point of few of an user and from the point of view of an information systems project manager within various ISP. I don’t have the depth of knowledge required for a critical look at this Nokia study. So I turned to a friendly industry expert who shall remain anonymous – here is his opinion :
[The study] isn’t really scientific enough testing IMHO. Surely most routers aren’t high performance due to cost reasons and most DSL users (Telco environments don’t have more than 8 Mbit/s (24 Mbit/s is max).
[Nokia] should check with real highend/flagships routers such as Linksys E3000. Other issues are common NAT issues or related settings or use of the box DNS Proxy’s. Also no real testing method explained here so useless IMHO. Our test plan has more than 500 pages with full description and failure judgment… :)
So take « An Experimental Study of Home Gateway Characteristics » with a big grain of salt. Nevertheless, in spite of its faults I’m glad that such studies are conducted – anything that can prod the consumer market into raising its game is a good thing !
