Audio/Video Conferencing and Interop within Lync Server 2010

Audio/Video Conferencing andInteroperability in Lync ServerJeff Schertz

Agenda Lync Server A/V Conferencing Capabilities Lync Server A/V Conferencing Architecture Video Interoperability

Lync Server A/V Conferencing Capabilities Audio via VoIP or PSTN (with appropriate gateway) Active-speaker video switching up to VGA resolution In conjunction with the Data and IM MCUs, provide full collaboration Policy-based administration  Collaboration enablement  Maximum video resolution  Sharing control  File transfer  Recording control

On-Premises Audio Conferencing Replaces ACP for ~85% of calls (Gartner) Requires PSTN Gateway deployment on-premises Features  Name Recording, Entry/Exit announcements (default OFF)  Supports Lobby for easy join (Presenters grant access)  Easy PIN management  Recording from Lync client  Rich language support for IVR

Supported Video Formats CIF (RTV and H.263) HD (RTV Only, P2P Only)• Common Interchange Format • High Definition• 352x288, 15 fps, 350 kbps • 1280x720(16:9), 25 fps, 1.5 Mbps • Cores: Dual (Receive) or Quad (Send) VGA (RTV Only) Panorama (RTV Only)• Video Graphics Array • Polycom CX5000 / RoundTable• 640x480, 25 fps, 700 kbps • 1056x144 (22:3), 15 fps, 650 kbps

Lync Server A/V Conferencing Architecture Collocated  Front End servers also have A/V MCU role  Good for small and medium deployments Distributed  Dedicated A/V MCU servers  Good for large deployments  Good for heavy conferencing

EE Pool with collocated A/V Conf ServersIdeal for  Medium size business  Regional DeploymentConferencing functionalities Browser Reverse  Audio/Video Conference Proxy  Web Conference (slide sharing, application sharing, Lync Server 2010 Front Lync Server 2010 whiteboard, etc.) End Servers Back End Servers  PSTN dial-in (requires mediation server and PSTN gateway) Lync 2010 Lync Server 2010  Group IM Edge  CWAScalability Outside Corporation Perimeter Network Data Center/Internal Network  Up to 10,000 users  250 user large conferences Inside Corporation

EE Pool with separate A/V ServersIdeal for  Large enterprise  Data center deploymentConferencing functionalities Lync Server Lync Server Browser Reverse 2010 Front End 2010 Back End  Audio/Video Conference Proxy Servers Servers  Web Conference (slide sharing, application sharing, whiteboard, etc.)  PSTN dial-in (requires mediation server and PSTN gateway) Lync 2010 Lync Server  Group IM 2010 Edge Lync Server 2010 A/V Conferencing Servers  CWAScalability Outside Corporation Perimeter Network Data Center/Internal Network  Up to 80,000 users  250 user large conferences Inside Corporation

Third Party Video Interoperability Native Approach  Built-in registration logic  May have other built-in capabilities (RTV, CCCP, etc.)  Main advantage is a consistent architecture Gateway Approach  Gateway performs registration  Gateway may also transcode RTV (may be an additional gateway)  Main advantage is time to market

Third Party Video Interoperability Regardless of technical integration approach, third parties add…  Cross-protocol interoperability (H.323, ISDN, TIP, etc.)  High definition conferencing  “Hollywood squares” experience  Multi-codec support (H.264, etc.)  Extension of Lync to room systems Each vendor has different approaches and capabilities within their solution set so make sure that the vendor you choose has the right integration and roadmap for your long term plan

Appendix – Polycom Solutions

Polycom’s Unique Architecture Solution Lowers Cost, Reduces Complexity, Increases Scalability, Provides Redundancy Polycom provides Direct Integration versus Gateway approach NO implementation complexity NO additional network overheadRMX 4000 NO single point of failure NO additional hardware or software licensing costs CX5000RMX 2000 DMA 7000 CX300 HDX 4000 HDX 6000 CX7000 CX3000 CX600

Microsoft Native Video Endpoints CX5000 (RoundTable) Collaborative meeting spaces Small conference rooms/informal table settings Possibly no central display/projector All/most attendees have laptops All/most other participants are at their desk CX7000 (Rally) Address the need for a Lync optimized conference room experience Simple Windows user interface Ideal for collaborative meeting with video Enhanced video quality (HD with high-end optics) Supports Lync Management and Monitoring

Microsoft Integrated Video Endpoints Telepresence Endpoints (HDX) Executive desktop systems and conference rooms Interaction with both H.323 and SIP Native Microsoft Integration OCS/Lync: Presence, SIP, Edge, ICE, RTV, CCCP Exchange: ‘Smart Rooms’ via EWS Immersive Telepresence (OTX, RPX) Across-the-table experience Based on same technologies as HDX Direct Peer-to-Peer video calling between ITP and Microsoft clients

Polycom RealPresence Platform RMX Extends Continuous Presence and High Definition conferencing to Lync clients Provides interconnectivity between SIP, H.323, ISDN, and PSTN endpoints over a variety of codecs (G.711, H.264, RTV, TIP, etc.) DMA Provides extensive scalability and redundancy features Virtualizes conferencing resources CMA Offers endpoint management and directory integration

Native Microsoft Integration OCS/Lync Integration Simple routing configuration Signaling (TLS) and media (SRTP) encryption Registration and Presence Virtual Meeting Rooms appear in the Lync directory with presence Searchable, just like users and HDX rooms Federation Support ICE compatibility for external/federated user Default SIP Domain support Higher Resolutions for Video and Content RTV VGA/HD people or content video streams Intelligent bandwidth usage
