This is very important for ISPs and I hope to receive some good feedback from this forum. Emerging technologies have got a Bandwidth Management Software. Costs around 500 USD per interface and each licence is coded to the ethernet address of the interface. Why don't you have a look at the http://www.etinc.com page? It is ET-BWMGR. Have installed it and am currently using it. It also has a burst manager, but we have not really had the timeto experiment and I have some serious doubts about how much thought bandwidth management solution providers are putting into the requirements of ISPs. Amongst the issues that are not addressed are: 1. Why drop packets when the retransmissions may cause greater problems and result in a negative effect on customers using bandwidth right to the limits of their contracts? 2. Usually demand is much greater than the available bandwidth. So there are going to be collisions anyway. 3. Has anyone thought about the need of limiting tcp sessions on permanent connection contracts? BT do it. 4. Has anyone thought about the need of limiting bandwidth per port? There is a lot of talk but experience is that much is in beta to the third! :-) Has anyone used Aponet's ABM-10/100 (http://www.aponet.com) or the Packeteer from Packeteer Inc.? I would greatly appreciate if we could use this as a forum for discussing bandwdith management techniques. It is still a very novel thing, but being ISPs using packet switching tech, we do not really go ATM and QOS etc from Cisco is still quite new. Any suggestions, experiences, things to avoid or look out for?
