2 Simplicity vs. Complexity Marketing Perspective Accessing the desktops or apps is simple The desktop consists only of a few layers Bandwidth is everywhere (WLAN, 3G, Edge) Apps behave similar User Workspace Applications Operating System Hypervisor

3 Simplicity vs. Complexity Admin Perspective Accessing the Desktop can be complex The Desktop consists of many layers Bandwidth is not everywhere (WLAN, 3G, Edge) Latency is Key Apps can behave totally different Client Device Network User Workspace Applications Runtime Environment Operating System Hypervisor Hardware User Admin

4 Simplicity vs. Complexity User Perspective There is still one layer left...

5 One Receiver different capabilities Different versions on different platforms. Not a single Receiver framework Different HDX feature sets dependent on OS platforms (i.e. no Flash on IOS devices) Different protocols ICA vs. CGP

6 The Citrix Mission Statement

7 Deliver the best user experience on the broadest range of devices across the widest selection of delivery networks. Mark B. Templeton CEO Citrix Systems

8 How can it be done? Where should I start? Answer: Make a plan!

9 A plan is typically any diagram or list of steps with timing and resources, used to achieve an objective. It is commonly understood as a temporal set of intended actions, through which one expects to achieve a goal.

10 A Technical Approach for User Experience Focus on your environment Know your applications Conduct a network assessment Conduct an user s device assessment Define your use cases

11 How to get a structure for better experience My Devices Windows based Mac OS Thin Clients iphone / ipad My Networks LAN MPLS (Branch Office) Site-to-Site VPN (Internet) Home Office 3G / Edge

12 My Devices Different Devices = Different Receivers Different Receivers = Different Capabilities Different Capabilities = Different Performance

13 Windows Devices Receiver for Windows Broadest feature set Complete HDX support Complete client device mapping support Fastest adaption of new features

14 Mac OS X Devices Receiver for Mac Broad feature set Good HDX support Good client device mapping support The challenger of the MS Windows world

15 Thin Clients Mostly proprietary Receivers Broad feature set Good HDX support Good client device mapping support Development and adaption of new features depends on vendor Features = Model = Costs

16 IOS Devices Receiver for iphone / ipad Broad feature set Fair HDX support Poor client device mapping support Currently limited use cases due to MS platform and apps

17 My Networks Different Networks = Different Speeds Different Networks = Different Availibility Different Networks = Different Latency

18 Local Area Network At least 100 Mbit bandwidth Nearly no latency Very good availibility I can manage it

19 Dedicated Branch Office Link i.e. MPLS Good bandwidth Very good latency Very good availibility My carrier can manage it

20 Site-to-Site VPN over the Internet Fair bandwidth - sync/async Good latency Cable, DSL,.. Good availibility I cannot manage the Internet

21 Wireless Connection using 3G / Edge Bandwidth It depends Latency It depends Availibility It depends Highly variable

22 Build the Puzzle Putting the pieceparts together

23 Define Your Device Use Cases - Example Network/Device Windows Mac OS X Thin Client IOS Local Area Network Yes Yes Yes Branch Office (i.e. MPLS) Yes Yes Yes Site-to-Site VPN Yes Yes Yes 3G connection Yes Yes Edge Connection Yes Yes Assumptions: Windows devices will be used everywhere imacs will only be used in the marketing department (headquarter and branches) Thin Clients will be used in all offices (headquater and branches) IOS devices will be used remotely by sales

24 Define Your Feature Use Cases - Example Feature/Device Windows Mac OS X Thin Client IOS Bi-directional audio Deny Deny Only Call Center Not supported Client Drive Mapping Yes Yes No Audio Playback Yes Yes Yes Flash Redirection Yes Yes Not supported COM Port Mapping No No Label Printer in Store Not supported Smart Card Authentication Only HR + Managers Not supported Only HR + Managers Not supported Time Zone Redirection Only Laptop Users No Foreign Branch No..

25 Identify the Conditions How can it be done?

26 How can I identify different devices? - When using the Citrix consoles Receiver for Mobile Devices will use mobile as client name Thin Clients normally provide their hostname. I.e. Wyse Xenith can be identified by WT* as default client name Windows machines will use their hostname in the internal network

27 How can I identify different devices? - When using Access Gateway Windows machines will identify as WI_* when using an Access Gateway as ICA Proxy The different Receivers provide different User-Agent strings which can be used for filtering with CAG EE aka NetScaler

28 Recommendation - Example Use naming conventions to identify devices based on: Vendors Types Models Capabilities Locations

29 No clue? Here you go

30 How can I represent the use cases in my environment This can be simply done by using policies Policies can be either defined in the Citrix consoles or by using the Microsoft Group Policy Management Console Citrix AppCenter (Xenapp) or Citrix Desktop Studio (XenDesktop) There is currently an issue that existing policy priority settings are not retained after editing and saving a policy. Further information and a hotfix can be found under CTX (XenApp) and CTX (XenDesktop)

31 Final Findings

32 Schematic policy definitions based on example Priority Policy Filter Setting Value 1 2 Client Printer in Home Office Client Printer in Home Office Clientname = WI_* Printer Mapping Enabled Clientname = WI_* Printer Mapping Only default Printer 3 IOS Devices Clientname = mobile All devices mappings Disabled 4 IOS Devices Clientname = mobile frames/second Thin Clients Clientname = WT* Client Printer Mapping Disabled 7 Unfiltered None Do not use client s local time Enabled 8 Unfiltered None Audio Quality medium Lowest Unfiltered None frames/second 15
