Just wondering if BIND can do GLB -Global Load Balancing Stuff?

[Mike Mitchell]

A long time ago I used a perl script called lbnamed that acted as a DNS server and would monitor hosts and change the returned results based on aliveness and load.
See http://www.stanford.edu/~riepel/lbnamed/

I understand BIND by default can not work like GLB but wondering if there are any patches available or any other Open source software community is aware of who can perform  such thing.

BIND does a sort of round robin to load balance among the IPs for a specific host; however, it does not monitor any health or routes and doesn't have the same capabilities as a GTM to choose what IP to answer for a name.
I've worked with F5 GTM to monitor and route traffic based on health, status, load, originator, time-of-day, etc. It depends on the model and modules you get that determine what can be done.
The implementation you use will be different than ours and should be based on testing what works best. The F5 technicians we work with are very helpful.

Hi Folks,

Can BIND work as a Global Load Balancer? Or I am keen to know about constructing GTM kindaa stuff which can monitor the health of devices and route away traffic from failed ones by putting lower TTL value? I believe F5 3DNS does the same thing?
