HDX Broadcast Session Reliability
HDX Broadcast Session Reliability allows a user to continue to view, but not interact with, a published resource on the screen of the user device when the connection to the server is temporarily interrupted.
• Maximizes system efficiency
• Provides pre-defined load evaluators
• Provides the ability to create custom load evaluators
Load Balancing
Load Manager balances server load across the farm by:

Streaming Applications
Application Streaming Benefits
Application streaming includes the following capabilities: • Local system resource usage • Central application updates • Isolation environments • Windows Services isolation • Inter-Isolation communication • Application caching • Dual-mode streaming • Offline access
• Using load evaluator rules to calculate server load
• Identifying which server is least-loaded
• Directing user connections to the least loaded server
Creating Load Balancing Policies
Force Application Streaming
• Streamed to client
• Accessed from a server: streamed to server
• Streamed if possible; otherwise accessed from a server: installed application • Streamed if possible; otherwise accessed from a server: streamed to server
Inter-Isolation Communication
There are two types of inter-isolation communication configurations: • Associated • Dependent

HDX Broadcast Session Reliability Considerations
Load Balancing Process
Creating Custom Load Evaluators
Load Balancing Policies
The decision behind which server is most appropriate is often based on business needs or technical limitations, such as: Directing users to a backup server Directing specific users to dedicated servers Reducing WAN traffic and improving user experience
Policy Processing and Precedence
Policy Rules
Policy Filtering
Policies can be:
• Unfiltered
• Filtered
Policy Modeling
The Citrix Group Policy Modeling wizard can simulate a user connection in order to test the policy settings. You can specify conditions for the simulation, such as: • Domain controller
• Linked to Active Directory domains, organizational units (OUs), and sites
IMA-based Group Policies
Group Policy Extensions
Policy Evaluation
Policies are evaluated on XenApp servers when one of the following events occurs: • A user logs on • The server is restarted • The policy refresh interval is reached • A policy update is forced • When the IMA service starts (for IMA-based policies only)
• Users
• Citrix policy filters
• Slow network connection

Configuring Load Management
Load Manager
Load Manager offers the following benefits to enterprises:
• Ensure that a XenApp Web or XenApp Services site is configured (Online or Dual mode)
• Ensure that the application is not installed on the XenApp server • Publish the application to stream to a XenApp server
Target Options
The target is selected from the profile based on a variety of criteria: • Operating System • Service Pack Level • System Drive Letter • Operating System Language
Citrix Offline Plug-in Benefits
To access a streamed application, one of the following combinations must be available: • Citrix Offline Plug-in and Citrix online plug-in • Citrix Offline Plug-in with a web browser
Profile Properties: File Types
Application Delivery Methods
The following delivery methods are available:
• Accessed from a server
• Streamed if possible, otherwise accessed from a server
Offline Application Caching

Configuring Policies
Group Policy Integration
Citrix policies are:
• Configured within Group Policy Objects (GPOs)
Specifying an Alternate Profile for a Published Application
Enabling the Least-Privileged User Account
Offline Access Management
Offline Access Period
Installing the Citrix Streaming Profiler
The profiling system run-time environment should be as close to the environment of the user device as possible. For example: • If applications are streamed to a XenApp server, the profiler system should also be a XenApp server • If applications are streamed to both 32- and 64-bit operating system user devices, there should be two separate profiling systems • If standard programs are part of the company image, they should be installed on the profiling system
