Hello?

Lync Demo Call


#AirheadsConf

Overview

Join us in this session to better understand the wireless networking requirements for mobile UC and best practices on

application level configuration.

• Mobile unified communication over Wi-Fi can:

– Impact the productivity for your end users in a big way

– Can enable chat, video conferencing, voice calling, file transfer, desktop sharing and web conferencing as part of a single mobile app• This reduces IT spending significantly

– The wireless network in place should understand all these different traffic flows, reporting on call quality, support high definition data transfer for video and more

Aruba at Lync Conference 2014

Sessions presented by:

Michael Tennefoss, VP Strategic Partnerships, and

Thenu Kittappa, Senior Manager Strategic Partnerships-UC SDN Task Group working on standardizing UC SDN scenarios and

certification and interoperability program

Aruba Networks: Can Your Network Walk The Walk And Talk The TalkLync 2013 hails the advent of the truly all-wireless enterprise in which the wired phone, birthed in the 19th century, is set aside in favor of mobile devices. In the mobile enterprise the demands on, and expectations of, the Wi-Fi infrastructure rise far above what’s needed for simple data access. End-to-end Quality-of-Service, BYOD on-boarding, application flow prioritization, and dynamic bandwidth management are essential. So is visibility into mobile applications, devices, and users. Six nines reliability requires proactive network management and speedy remediation of issues affecting voice and video quality. This presentation will discuss how the new Lync SDN API brings end-to-end visibility to calls in flight, root-cause problem identification, application usage, device performance, and user behavior. Acknowledging that many potential Lync 2013 prospects may not be mobility-ready, the presentation will also discuss the role and importance of a Lync Mobility Readiness Assessment.

Software Defined Networking: Wi-Fi and Lync Wi-Fi presents unique challenges to Unified Communications. In this session we will explore how Software Defined Networking (SDN) can be used with Lync specifically to address the common Wi-Fi deployment issues. Together with Aruba Networks we will showcase how SDN technologies can be leveraged to provide great quality for the mobile devices and people in your enterprise

Challenges

• The demo gods are not always kind!• Varied use cases across the business

• To record or not to record• How long is long enough?

• Network issues cause 60-80% of poor end-user QoE• Poor Visibility into real-time traffic– Lync uses encryption by default, making DPI difficult and unreliable

– Skype tries to hide itself from networks

• Traffic engineering/ QoS is complex & easily broken– Requires brute force static policies that must match application server settings

– Intermittent problems are tedious to diagnosis, especially for Softphones and BYOD


#AirheadsConf

Aruba MVP Award

• Aruba MVP: Joel Chavez, IT Helpdesk, won the MVP Award at Aruba For Q2 in FY14 for his outstanding job training Aruba employees on Lync

Joel hosted over a dozen training sessions after teaching himself Lync features. Aruba Networks as a Company voted him as an MVP this past quarter.


#AirheadsConf

Common Issues

• Client Issues– New skillset requiring user adoption and training

• Network- What can our network see?• Resource– Skillset, coverage

• New technology: SBC, PSTN carries and solution

• Budgeting & Reporting

• Call quality and drop issues

• Customer adoption and training

• Headsets

• True test of wire-equivalent Wi-Fi network

#AirheadsConf

Lync Architecture Best Practices

• Server roles– Front End, Database, Monitoring, Archiving, Mediation,

Edge, & Persistent Chat

• Define business needs with respect to functionality, geography and resiliency

• Every site doesn’t necessarily need resiliency• Build Front end and Edge pools near high

concentrations of conferencing• Be cautious with virtualization• Don’t forget about the network!

Key Takeaways

• Many opportunities for partners and service providers to provide Lync services

• Lync Technology is an Enterprise level solution with huge growth potential

• Voice is the largest challenge of a managed environment• Key innovations from Aruba show the commitment to Lync• Aruba has a huge opportunity to be a leader in the unified

communications market• SDN is a very influential aspect of the landscape• Integration to other apps such as SharePoint and Outlook will

be key to user adoption• Lync room systems are one of the most advanced aspects of

the space


#AirheadsConf

SDN API


#AirheadsConf

SDN API

• What is it? – Toolset to allow network equipment to access detailed data

about the Lync platform

– Real time call data

– Adaptive, real time prioritization, and QoS

– Aruba is the only qualified solution to optimize Lync

• SDN brings together network infrastructure and unified communications– Lync server can now interact directly with network

infrastructure so QoS and services can be dynamically adjusted to always deliver the best possible experience


#AirheadsConf

Applications Programming Networks-SDN Architecture

• SDN Application– Communicate using Northbound

interface to SDN controller

• Controller• Translate requirements from

Applications

– Provide an abstracted view of the network

• Network Elements • Could be physical or virtual • Communicate to Controller

via Southbound / Control-Data-Plane Interface


#AirheadsConf

Lync SDN Strategy

Diagnostics

Proactively automate the diagnostics and troubleshooting of bad calls

Automated QoS

Reduce the cost of deploying QoS and implementing Traffic Engineering.

Orchestration

IT Agility & Network Customization through real-time, policy-based configuration of network resources.


#AirheadsConf

SDN API


#AirheadsConf

SDN API

QoS Includes:• Identification and prioritization of Lync traffic based on individual

voice, video, and desktop sharing traffic streams

• Traffic retagging ensures that over-the-air Lync traffic receives the right priority level even if the wired network infrastructure misprioritized or mistagged the traffic

• Lync-aware RF Management ensures that jitter and packet loss are not introduced by the Wi-Fi infrastructure

• Lync-aware roaming takes Lync call status into account when enforcing client roaming for sticky clients, part of a patented technology and Client Match


#AirheadsConf

Debugging Internally

• Microsoft partnership has allowed Lync SDN API to integrate with Aruba’s Wi-Fi controllers– Aruba is the only Wi-Fit solution that identifies and differentiates

encrypted Lync traffic types

• Controller Configuration:– Configuration > Management > General > Configure Lync:

• Aruba Wi-Fi controllers leverage the Lync SDN API to proactively identify, troubleshoot, and prevent issues that could affect Lync quality


#AirheadsConf

Debugging Internally


#AirheadsConf

Debugging Externally
