The BIG-IP® Global Traffic Manager and Link Controller: Implementations
guide is designed to help you accomplish specific configuration tasks associated with the Global Traffic Manager or Link Controller. Each chapter focuses on a specific scenario, providing an overview of the situation to which the implementation applies, and a detailed example of how to configure the system to accomplish the objectives outlined in the implementation scenario. The steps outlined in each chapter are designed so that you can quickly apply them to your own network.
Before you begin configuring an implementation, we recommend that you
run the Setup utility on the Global Traffic Manager or Link Controller to configure basic network elements such as self IP addresses, interfaces, and VLANs. After running the Setup utility, you can use this guide to implement specific configuration scenarios.
Global Traffic Manager is a system that monitors the availability and performance of global resources and uses 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.
Link Controller is a dedicated IP application switch that manages traffic to and from a site across multiple links, regardless of connection type or provider. The Link Controller provides granular traffic control for Internet gateways, allowing you to define how traffic is distributed across links in a way that meets your business priorities. The Link Controller also transparently monitors the availability and health of links to optimally direct traffic across the best available link.
Each of these implementations includes sample network information, such
as IP addresses and other configuration settings, which provides context for the implementation. You can use the scenarios included with each implementation as a template, replacing the sample data with the corresponding data from an actual network.
