I am wondering if anyone here has done network interface bonding[1] using 2 x ADSL connections from the same provider?This is for a location where only Bell ADSL is available, and only at 5Mbps. I am wondering if having 2 (or more) services at the same location is possible (I am calling Bell) and if it would effectively double (or at least increase) the bandwidth available when combined by bonding network interfaces on a router appliance dedicated to that. I am asking Bell if having 2 circuits at the same location would deliver separate "guaranteed" 5Mbps or if it would be shared anyways. I've heard about this same scenario used with different providers to ensure if one goes down service continues, but not with the same provider twice. The goal here is not high availability, just higher speeds. If anyone has other creative solutions to improve a link in such a situation, I am listening :)
A few ideas to deal with low bandwidth in general:- configure (or enforce) DNS and web proxy/cache at the gateway => it will reduce the bandwidth load and thus enhance bandwidth availability => FLOSS solutions I'd use for that: bind or dnsmasq, squid, either iptables to enforce redirecting traffic to the proxy or using a "proxy.pac" for collaborative auto-proxy configuration
- configure QoS at the gateway => sometime it's not that much about speed than about latency, for example people want to keep a good audio/video call quality while there is large downloads in progress ; => FLOSS solutions I'd use for that: iproute (tc and ip rule), iptables, shell scripting => most modern router equipment already have it, but sometime it's just not activated by default
- tunnel all network traffic at the gateway to a network node you own, one with perfect bandwidth to your location (= you're able to get the top speed between them) and a higher bandwidth to Internet => compress the raw network traffic between your location and this node and you'll be able to get higher speed, at the cost of a bit more latency (won't be a problem if the network node is nearby, especially at the same ISP). => FLOSS solutions I'd use for that: OpenVPN with LZO compression (may be the easiest way), vde2 tunnels with compression, IPv6 link with IPcomp, …
You may also mix multiple solutions, using for example iproute (ip rule) to redirect traffic accordingly.
