Appendix H - Deployment Into Microsoft Environments

Sharing Content During a Conference

Two implementations of the Content Sharing Suite (CSS) are available in Lync 2010 and Lync 2013 environments:

●RealPresence CSS Gateway

●RealPresence CSS Plug in

RealPresence CSS Gateway

The CSS Gateway provides Content interoperability between Lync clients and non Lync clients in a conference. Lync clients connected to a Lync AV MCU use their native Content protocol, RDP (Remote Desktop Protocol) and Polycom endpoints, use their native SIP BFCP Content protocol, to send or receive Content, to or from the CSS Gateway, which renders a RDP  SIP BFCP Content stream.

The Gateway functionality was previously enabled by a combination of: Content Add-on for Lync; Content Sharing Server; and BFCP Content-Only Client Plug-in. These functionalities have been incorporated into the CSS, eliminating the need for plug-ins. The CSS Plug in is still supported for backward compatibility.

For more information see: RealPresence CSS Plug in

Unified Communications Deployment Guide for Microsoft Environments

The Gateway allows Polycom endpoints, using native SIP BFCP, and Lync clients, using native RDP, to share Content in a conference.

CSS Gateway Usage Guidelines

MS AV MCU Cascade is the only Deployment Architecture that is supported. For more information see Deployment Architecture 2 - MS AV MCU Cascade.

One CSS RDP Gateway connection is supported per conference in the Collaboration Server, initiated by the DMA through the CSS server.

There is no Lync client associated with the CSS Gateway connection and even if the AV MCU is empty the CSS will be still be connected. The Collaboration Server does not consider the CSS RDP Gateway connection as a participant and if the conferences on both the Collaboration Server and the AV MCU are empty it will disconnect the CSS RDP Gateway and the AV MCU link.

When a Content sharing endpoint is detected by the Collaboration Server side the CSS RDP Gateway will receive BFCP message triggering the RDP session on the Lync side of the topology.

RealPresence CSS Plug in

For backward compatibility the Collaboration Server supports Content sharing using either the CSS Gateway or the lug-in based Content sharing solution, however not in the same conference.

Using Polycom CSS Plug in, Lync 2013 clients are able to share content in Polycom Content sessions in both Collaboration Server Hosted calls and Cascaded Lync 2013 AVMCU calls, with both Lync 2010 & 2013 clients.
