i have win2k8 DC, and squid proxy server .. i have 2 DSL connection, squid is using DSL1, DSL2 is normally used as a backup when DSL1 goes down.. i have allowed a lot of users streaming websites i.e youtube.com etc which normally consumes a lot of bandwidth and our DSL1 is having limited volume.

i want to distribute http traffice b/w DSL1 and DSL2, is there any way that whenever user access the streaming website i.e youtube.com, its traffic automatically redirects to DSL2 rather than squid (DSL1).. how can i add route.. where it will be added or is there any other way.. thanx

i think the simplest option is to add another squid proxy with DSL 2  as gateway, and assign heavy streaming users to it.

You could try to add routes to specific subnets (for example 74.125.79.x for Youtube) to use DSL2 as the gateway. The problems are that you don't have the target subnet mask (have to guess it) and you will not be notified of destination IP changes. And you also have to keep track of the target sites having the most traffic and add/remove those subnets separately. It will certainly bring administrative burden.

Some hardware load balancers may have possibility to reroute specific protocol types such as RTSP, but this option will have very high price tag on it.

Toxacon is correct.  The only way to do this inexpensively is to add static routes for that hosts you want to use DSL2.

I don't know your setup, but you should be able to add the routes on the box you are running Squid on and that way you just add the routes to one place and not to every desktop.

Most sites like youtube will have multiple IP addresses and some will be spread across different IP subnets.  So you may not be able to just add a single subnet and get them all.

The other thing you could do with Squid is to setup bandwidth buckets so that it (Squid) throttles the amount of bandwidth used when going to these hosts.  That way not only do you route them to a different Internet connection, you limit the bandwidth they consume.
