Global Traffic Manager
You can use the BIG-IP® Global Traffic Manager™ system to monitor the
availability and performance of global resources and use that information to
manage network traffic patterns. The Global Traffic Manager uses load
balancing algorithms, topology-based routing, and iRules® to control and
distribute traffic according to specific policies.
The Global Traffic Manager provides a variety of features that meet special
needs. For example, with this product you can:
• Ensure wide-area persistence by maintaining a mapping between a local
DNS server and a virtual server in a wide IP pool
• Direct local clients to local servers for globally-distributed sites using
Topology mode load balancing
• Change the load balancing configuration according to current traffic
patterns or time of day
• Customize load balancing modes
• Set up global load balancing among Local Traffic Manager™ systems
and other load balancing hosts
• Monitor real-time network conditions
• Configure a content delivery network with a CDN provider
• Guarantee multiple port availability for e-commerce sites
The Global Traffic Manager is one of several products that constitute the
BIG-IP product family. All products in the BIG-IP product family run on the
powerful Traffic Management Operating System®, commonly referred to as
TMOS®.
When you install a Global Traffic Manager system on the network, the
actions you take to integrate it into the network fall into two categories:
setup tasks and configuration tasks.
◆ Setup tasks are tasks in which you create or modify settings that apply to
the Global Traffic Manager itself, or that apply universally to all other
configuration components, such as servers, data centers, or wide IPs that
you create later. Examples of setup tasks include running the Setup
utility, assigning self IP address, and enabling high-availability
functions.
◆ Configuration tasks are tasks in which you define a specific aspect of the
Global Traffic Manager, such as load balancing methods, pools and pool
members, or iRules. These configuration tasks, while important, only
affect specific aspects of how you manage DNS traffic with the Global
Traffic Manager.
