Network Management
Comcast is committed to providing the best online experience possible for all of its customers. The company uses reasonable network management practices that are consistent with industry standards. Comcast maintains an Acceptable Use Policy ("AUP") located at
http://www.comcast.net/terms/use/ for its Comcast High-Speed Internet customers. The AUP and the frequently asked questions ("FAQs") located at
http://www.comcast.net/help/faq/inde...anagement19163 discuss why Comcast manages its network and how it may do so.
Network Management Trial
The company announced in March 2008 that it will switch to a new network management technique by the end of the year for managing bandwidth use and congestion. This new technique does not look at particular protocols or applications. Instead, it will focus on the bandwidth consumption activity of individual customers who are contributing to congestion on Comcast's network. The technique measures only aggregate bandwidth consumption, not the protocol or content being used by customers.
The first step for using this new network management technique is to run a trial of the technology in a market of Comcast High-Speed Internet customers. The trial will allow Comcast to better understand how this technique works in a "real world" setting. It will also let the company try different settings and learn from trial results in order to fine tune this new technique so Comcast can deliver the best online experience possible for all of its customers.
Comcast will run the first trial of this network management technique in the Chambersburg, PA and Warrenton, VA areas. The company currently expects to start the trial on June 5th and run it for 30 days.
How Does the New Network Management Technique Work?
The new network management technique is designed to ensure, to the greatest extent possible, that all Comcast High-Speed Internet customers have fair and equal access to the Internet and to bandwidth resources. Without it, some customers would experience poor performance ? for example, slow access to e-mail, sluggish web surfing, or low quality streaming audio and video ? during periods of network congestion.
Most customers will notice little to no change in their Internet experience when the new network management technique is working to help deliver a consistent, excellent online experience. The new network management technique will result in delayed response times for Internet traffic only for those customers who are using more than their fair share of available Internet resources at the time. The network management technique manages those customers' Internet traffic until their usage falls below established bandwidth usage thresholds or until network congestion ends.
During this trial, Comcast will learn more about how this network management technique will affect customers. Comcast expects that network management will only affect a small percentage of users during periods of network congestion, while ensuring an excellent online experience for the vast majority of our users.
We will provide periodic updates on this webpage on our trials and our progress in transitioning to this new network management technique.
