Agenda


The rise of Unified Communications

3

Dimension Data: Over 75% of surveyed customers have budget to

implement Unified Communications

Transparency Market Research: The global UC market is estimated to be in

excess of USD 16 billion by 2015

ResearchMoz: Unified Communications Market Growing at a CAGR of 15.7%

from 2012 to 2018

Companiesandmarkets.com: The Global Unified Communication market is to

grow at a CAGR of 15.9% over the period 2012-2016

Login Consultants: 43% of existing VDI customers are implementing UC


How can I deploy Lync on Virtual

Desktops?

“Lync is a strategic app for us now”3 out of 4 Citrix customer conversations about UC

are about Lync

90 of the Fortune 100 use Lync

Est. 10-15M seats deployed as of mid

2014, equiv. to ~50% of Citrix’s total

XA/XD user count


Microsoft Lync on XenDesktop & XenAppWhat methods of delivery are there and how to decide which method of delivery is best

•Citrix offers the broadest connectivity

options for Lync

•4 Connection options available

•No changes to existing Lync backend

infrastructure, Support Lync 2010 & 2013


Method 1: Generic Media over ICA

Lync Runs in the Data Center

Benefits Considerations

Excellent Feature Use High NW Usage - “Hairpin Effect”

Windows, Mac & Linux Lower Scalability - Processing on the Server

Average Performance (H.264, Audio

Codecs, Webcam Compression)

Useful as a fall-back option

User 1

User 2


• Optimized-for-Speech audio codec (quick encode, 16-32 Kbps per channel)

• Webcam Video Compression (300-600 Kbps)

• UDP/RTP Audio transport (resilient to network congestion and packet loss)

• Adaptive Display (video quality and frame rate self-adjust to the network)

• Multi-stream ICA with packet tagging (DSCP and WMM) for QoS

• Jitter buffering and echo cancellation in Citrix Receiver for Windows

• Audio plug-n-play

• Audio device routing (e.g. ringtone to speakers, audio to headset)

On iOS and Android, we expect users to mostly use the native Lync app

Generic HDX Realtime


Method 2: Local App Access

Lync App Runs on Local Desktop


Good Feature Use No Application Sharing (just DT sharing)

High Server Scalability Only Windows Endpoints

Peer to Peer You need XD/XA Platinum Edition

User 1

User 2


Method 3: Optimised Approach (Microsoft)

Method 4: Optimised – Citrix Op. Pack Best

combination – Scalable, cross platform

Method 1: Everything happens in the DC,

scalability and performance suffers


Summary of Options

2) Local App Access - Scalability good but

Windows endpoint-only and hard to manage

3) Optimised – Microsoft VDI Plugin

Scalability good but Windows endpoint-only

Method 4: Optimised – Citrix Op. Pack

How do we compare to “the other guys”?

The Microsoft VDI Plugin is the method of choice for VMware Horizon 6

…. as long as your infrastructure looks like this

The other guys are great for Virtualising Lync

Best Practices for testing virtualised Lync


Lync Authentication with the OPLCertificate Authentication (TLS-DSK) - Preferred Method

•Credentials and certificates

given by web proxy can be

stored in the registry and

credential store for SSO

•RTCL gives these to the

RTME to authenticate Lync

• If all else fails, the user will be

asked for credentials twice at

login

•Note: TLS-DSK must be used

by Office 365

Full Details of Authentication flow here: http://support.citrix.com/article/CTX135647

http://support.citrix.com/article/CTX135647


Lync Authentication with the OPLNTLM Authentication

Lync authenticates to the

front end server directly

RTCL passes these to

the RTME so it can sign

in

If save password is

disabled, the user will be

asked to login again by

the OPL

Full Details of Authentication flow here: http://support.citrix.com/article/CTX135647



What’s the scope of your PoC?Checklist of Factors

• Number of test clients • XenApp Environment/Version(s) • XenDesktop Environment/Version(s) • Receiver Version(s) • Linux (Yes/No, flavor) • Windows (Yes/No, flavor) • Mac (Yes/No, Version) • Thin Clients: OS and Models• Lync Server Deployment (On Prem (2010, 2013), Office 365) Ed?• Lync IP Phones? (Yes/No, Model(s)) Ed?• Lync USB Sets? (Yes/No, Model(s)) Ed?• Webcams? (Yes/No, Model(s))• Is Lync used as the Phone System (Yes/No) Ed?• Do remote workers connect through Lync edge server (Yes/No) Ed?• Authentication Method (NTLM/TLS/Kerberos, Smartcard)

• If smartcard, which one?

• What method of Delivery? • Published App?• Published Desktop?• VDI?

• What tests will be performed?• What benchmarks do you have?• Are you testing long haul connections?• How will you measure Success?• Do you have a Lync expert onsite?• Do you have scope to reconfigure the backend?• Can you modify your firewall?• Will you be running network traces?


PoC Guidelines

•Make sure native Lync works already from any endpoint locations you’re considering

•Ask for Lync test accounts (relying on personal accounts can hinder testing if those people go into

meetings, calls etc.)

•Ask for test devices (Using personal hardware slows things down)

•Define which tests need to be performed and success criteria

•Limit the make/model of hardware tested to reduce variables

•Not all h/w is created equal (e.g. Webcams). Have multiple types on hand in case of issues

•Advise having a “Lync Expert” that can be on hand & modify the backend infrastructure (e.g.

policies, authentication)

What about NetScaler and Lync?
