There is a sub-set of the load balancing market that focuses on ISP
link load balancing. It is significantly less costly than the
"application-focused" load balancing technologies out there, and is
commonly provided by the same companies. Many of them provide advanced
link health-checking that would allow you to load balance links and
more heavily utilize those links that cost you less $$$ and/or get you
better performance. F5's Link Controller line is probably best in
functionality, although the price reflects that. Radware is a close
second with a better price, and a company called FatPipe has done only
this.
If the business really needs high performance and high availability
from internet/WAN links, this stuff is cost-justified. If the high
performance is just a "nice-to-have" for 20 users, then the other
recommendations on this thread would be a better choice.
