Re: [SQU] Squid box with two seperate Internet links

I don't think I understand what you mean by #1 below...for number 2, the
answer is:

This is not a Squid question, but a routing question. While it is
possible to balance between multiple upstream caches (and there are
patches on the SourceForge Squid site regarding this), if you are
instead balancing between network links then it is a routing issue, that
must be dealt with at the network level.

Squid goes out whatever route your OS tells it to go out for
requests...so if you set up balancing of some sort (BGP, Multipath,
static routing based on the last octet, etc.) at your router, then Squid
will be balanced in the same way as all of your other traffic.

If I were configuring a network divided as yours is (satellite, and land
link) I would use QoS queueing to send latency intensive stuff (like
http) over the land link, and get larger, but less interactive stuff
(like ftp, streaming media, etc.) from the satellite. Plus I'd overload
onto the satellite link for all traffic when the land line is thoroughly
saturated.

But deeper discussion of all of that is probably more appropriate on a
networking and routing list, where networking and routing nerds are more
able to provide solid advice, and working examples.

Hope this points you in the right direction, anyway.
