7. 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

11. 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

12. 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
