How to Use This Guide

This guide is organized as follows:

Chapter	Description
Chapter 1, Content Load-Balancing Overview	Assist you in understanding load balancing on the CSS by providing information about the relationship of service, owner, and content rules, and describes how the CSS handles TCP and UDP traffic.
Chapter 2, Configuring Flow and Port Mapping Parameters	Configure flow and port mapping parameters for the CSS.
Chapter 3, Configuring Services	Create and configure services. This chapter also provides information on activating and suspending a service and displaying service information.
Chapter 4, Configuring Service, Global, and Script Keepalives	Configure service, global, and script keepalives. This chapter also provides information on how to display keepalive information.
Chapter 5, Configuring Source Groups for Services	Configure source groups for services. This chapter also provides information on source group port mapping and displaying source group information.
Chapter 6, Configuring Loads for Services	Configure the relative and absolute load for services. This chapter also provides information on how to display global load information.
Chapter 7, Configuring Server/Application State Protocol for Server Load Balancing	ConfigureServer/Application State Protocol (SASP). SASP allows global workload managers (GWM) to monitor backend servers and their applications. The GWM uses SASP to send updated service weights to the CSS for load balancing decisions.
Chapter 8, Configuring Dynamic Feedback Protocol for Server Load Balancing	Configure Dynamic Feedback Protocol (DFP). DFP allows load-balanced servers (both local and remote) to dynamically report changes in their status and their ability to provide services to a CSS.
Chapter 9, Configuring Owners	Create and configure owners. This chapter also describes how to configure owner attributes such as a DNS balance type, address, billing information, case sensitivity, and DNS type.
Chapter 10, Configuring Content Rules	Create and configure content rules. This chapter also describes how to assign a content rule to an owner, configure a virtual IP address, add a service to a content rule, and activate, suspend, and remove a content rule.
Chapter 11, Configuring Sticky Parameters for Content Rules	Configure sticky parameters for content rules such as subnet mask, inactive timeout, string range, string operation, string prefix and string skip length.
Chapter 12, Configuring HTTP Header Load Balancing	Configure HTTP header load balancing including creating a header field group, configuring a header field entry, associating a header field group to a content rule, and showing header field groups.
Chapter 13, Configuring Caching	Configure content caching for proxy, reverse proxy, and transparent caching configurations.
Chapter 14, Configuring Content Replication	Configure demand-based content replication and content synchronization using publisher and subscriber services on a CSS.
