We have and ADSL link via Easynet. I'd like to increase our bandwidth further. This leads to 2 questions in my mind: Should I use a different ISP? How can I configure one proxy server to balance use of 2 adsl lines? Any comments or ideas, please.

One possible method of balancing 2 lines would be to do this i think: Have 3 boxes in all. Box 1 runs squid and receives the requests for pages from the workstations. It then has boxes 2 and 3 set up as round-robin parents (http://www1.gr.squid-cache.org/Doc/Hierarchy-Tutorial/tutorial- 5.html#ss5.10) so will forward requests to them equally. Boxes 2 + 3 have two network cards, one on the same subnet as box 1, and then one on the ADSL (box 2 on adsl line 1 and box 3 on adsl line 2). They will be used equally as box 1 will be fair in its round-robin so both lines will be used equally. I hope this is clear enough - I'm confusing myself writing it but I think you get the gist of it.

I use Easynet too - and have noticed a serious degredation in service over the last year, probably due to contention. Day times - especially around midday we find our bandwidth falls to little better than ISDN rates which would indicate almost complete useage by all contending clients. maybe Easynet group all schools onto the same DSLAM switch. I have looked at Demon's contention of 5:1 which should be better but I suspect that all users subscribing to that would be heavy users - possibly at other times as well as midday - although it might make the upload better which we use for VPN access for external clients such as staff and some pupils.
