I am seeking a very basic tutorial on the workings of the F5 Global traffic (GMT) load balancer and how it works with the local traffic (LMT) load balancer.


Please don't refer me to the F5 website.

thanks

GSLB (F5 Global Traffic Manager - GTM) and Local LSB (F5 Local Traffic Manager - LTM) work the same way for all manufacturers:

Global loadbalancing is DNS based: it takes the DNS request from the client (www.example.com) and based on rules, gives back the IP address(es) of one or more datacenters around the globe. The rules can be geographical, least loaded, etc.

Local loadbalancing is usually based on NAT or ARP hacking, where the loadbalancer has a "virtual IP address", seen by the clients, and the loadbalancer handles out connections to real servers (usually with different IP addresses) based on a set of rules.

Check out the "Brocade IP Primer" (http://www.brocade.com/downloads/documents/books/Brocade_IP_Primer_eBook.pdf) for a medium-level overview of the process, with more details on local loadbalancing.

In its most simplest form GTM load balances between virtual servers that are defined within LTM.  The virtual servers can reside on the same F5 running LTM or they can be on different F5's running LTM.
