Re: ISP QoS Architecture Question [7:49767]
No, we have loads of bandwidth, but I have heard some people, including Cisco Engineers claim that bandwidth won't solve your delay problems.

Re: ISP QoS Architecture Question [7:49767]
Jay, Does this mean you have determined your network is the bottleneck of your http traffic? If you think the congestion in your network is slowing down the response time, then doing the QoS stuff surely will help, of course, as long as the traffic stays within your network, but why adding bandwidth to solve the congestion problem is not a choice? I think it is better than playing with QoS. If you want to go down this road, you may also want to make sure the users could verify that your network is not slowing down their http traffic, if you only prioritize http, the users may use ping to verify the response. you could add icmp to high priority too, but why not just giving icmp a high priority, this way they will always see your network is responding pretty quick :-). I think there are some networks are selling QoS as a service, but IMHO if you just want to improve the response time, it may not be worth the trouble.

Re: ISP QoS Architecture Question [7:49767]
There are a lot of "Cisco Powered" networks doing QoS, but more for multi-service type stuff for voice and video. If you look on Cisco's web-site, there's a whole program your ISP can join to become "Cisco-powered" in multiservice, although I don't know the exact search terms you'd need to find it. If you want to join, Cisco will tell you in technical detail what you need to do for QoS. I imagine it's just stuff under the MQC, but I never bothered to ask. In any case, I don't think giving lowly http priority is the best business decision you can make. It's TCP based so it can handle delay, plus you have no control of the http traffic once the user leaves your network onto another, so all the time and effort you place into it, may be all for naught. Even if you give http A+ traffic rating, as soon as the user goes to another network peer, it may be congested.

Re: ISP QoS Architecture Question [7:49767]
Hi, I Have made a document about QoS IP (but unfortunatly in french) If many people are interreted i will translate in English. So You have to consider the kind of application you have on the ISP : is there Netmeeting, voice/video traffic. Is there FTP ... Or others kind of applications. Do not forget routing protocols which must be the highest priority. Practicaly, you have to : - know each kind of traffic (applications). - share the bandwith - use Diffserv model (voice/video->EF; http->AF; FTP->best effort) - apply the model to the interfaces see for example: http://www.cisco.com/warp/public/105/qos_faq.html http://www.cisco.com/warp/public/105/dscpvalues.html http://www.cisco.com/warp/public/cc/pd/iosw/prodlit/difsf_ds.htm Best regards -- [EMAIL PROTECTED] Computing networks & internet specialist http://www.a01faure.com Certified Cisco(ccie #8935,ccnp+cvoice), Microsoft(mcse nt4) tel./fax. 33 (0)1 45 87 95 07 PARIS(FRANCE) ""Jay Greenberg"" a icrit dans le message news: [EMAIL PROTECTED] > I am considering deploying QoS features in our ISP.

ISP QoS Architecture Question [7:49767]
I am considering deploying QoS features in our ISP. The ISP has about 60 thousand users in total, and I was thinking of setting a general traffic policy.E.g., I would like to set HTTP traffic down to a very low delay, to make the network seem faster to end users. I suppose what I am asking is - has anyone done this for an ISP, and if so, how did it turn out?
