In 2006, I wrote a short blog post on why there is no Internet QoS and likely never will be. That post is a continuing source click throughs and email inquiries so, when Jon Arnold asked me to write a guest article for IP Convergence TV, I thought I'd tackle the definitive story on Internet QoS.
Here is the new article: Why there is no Internet QoS. It may or may not be definitive, but I have filled in the engineering and economic background, and I investigate where QoS has been deployed in networks in order to identify where there may be QoS related opportunities for ISPs.
- There is no Internet QoS today, and it’s unlikely any complex QoS scheme will ever be added to the Internet as a whole.
- To the extent next generation networks with rich QoS are deployed, this will only happen within walled gardens, not as part of the public Internet.
- But there may be opportunities for ISPs to create a simple premium service that could generate incremental revenue.
