Current Trends

• Voice as a “standalone application” is going away

• SIP, SCCP, SVP, H323, Vocera, NoE

• UCC is the “new wave” in IT• Skype, Lync, FaceTime, Jabber, Hangouts etc. • Next “BYOD” problem

@ArubaNetworks


Why Microsoft Lync?

• Integration with AD, Outlook, Office etc.

• Unified mobile client for BYOD

• On-premise and Cloud based deployment models

• Enable collaboration with mobility

• Strategic partner and customer of Aruba

Challenges with UC over Wireless

@ArubaNetworks


Challenges with UC over Wireless

• Diversity of Clients

• AV

• App incompatibility

@ArubaNetworks

• AP placement

• Channel Capacity

• AP Capacity

• Tx/Rx Characteristics

• Interference

• Mobility

• QoS on wireless • QoS on wire

• Queue overflows/drops

• Routing/path changes

• WAN

• UC server monitoring


Essentials to support Lync over Wi-Fi

• Classification & prioritization of Lync

• Wi-Fi optimized for Lync

• Real time and pro-active visibility

Lync

@ArubaNetworks


Types of Lync Deployments

• Lync On-Prem• Lync server farm is hosted on premise

• Hosted Lync• Lync server farm is hosted on a private cloud

• Lync Online• Lync server farm is hosted by Microsoft


Lync On-Prem/Hosted Lync

Exchange Server

QoE Server/Monitoring

Active Directory

Lync Federated Partners

Reverse Proxy

Lync Edge Server

Lync FE Server Pool/Lync SDN API Dialog Listener

Lync SDN Manager

Internet

Wi-Fi Mobility Controller

• Benefits from all Lync Server functionalities

• Maximum flexibility

• Interoperate with other on-premise investments

• Works with Exchange and SharePoint

Lync Online

@ArubaNetworks

• Uptime Assurance

• Using corporate directory

• Reduced administration

Lync Call Type/Flow

@ArubaNetworks

Call Type Signaling Traffic Media Traffic

Peer-to-Peer Session

Lync server pool

UC endpoint <-> UC endpoint

Conference Session UC endpoint <-> Lync server pool

PSTN/Mediation session UC endpoint -> (Mediation server)* -> PSTN gateway/IP

PBX

Content Sharing UC endpoint <-> UC endpoint/Lync server pool


Lync Network Bandwidth Requirements

Modality Description Max BW Typical BW

IM, Presence and signaling

Nonmedia elements 2 Kbps 1.6 Kbps

Voice RT Audio Wideband 62 Kbps 39 Kbps

Conference voice G722 100.6 Kbps 46.1 Kbps

Video - small H264 at 320x180 250 Kbps 200 Kbps

Video - medium H264 at 640x480 800 Kbps 640 Kbps

Video - high H264 at 1280x1080 4 Mbps 3.2 Mbps

Lync Aware WLAN

@ArubaNetworks


Lync Classification Methods

• Heuristics

• SDN API


Lync Classification using Heuristics

• Leverages DPI to identify & prioritize real time voice and video traffic

• Ideal for Lync online deployments• On-Prem deployments without SDN API can

leverage heuristics

• AirWave aggregates network wide data for visibility

Lync


Lync Classification using SDN API

• Lync server integrates with mobility controller using SDN API

• Real time call info is shared with mobility controller

• Controller leverages the info to apply QoS

• Ideal for On-Prem Lync deployments

• AirWave aggregates network wide data for visibility

Lync


Call Details via SDN API

Lync

• CALL START• Caller/callee, device, session, BW, time etc.

• PERIODIC INTERVALS• Instantaneous Call quality

• CALL END• Avg. call quality, time etc.
