For application sharing you will also need to specify ASMCUSVC.exe in the QoS GPO in addition to defining these port values.Īpplication Server QoS/VbSS required settings PropertyĮach Front End Server running Skype for Business Server 2015 Cumulative Update 2 (CU2) or later supports up to 375 participants for screen sharing using RDP (though only 250 per meeting). This overrides other recommended settings in the documentation for QoS. These settings are a special case, and these exact settings must be used when implementing both of these features. If QoS is enabled for the following media ports and VbSS is also enabled, during a conference that includes desktop sharing the AS MCU will use the video port settings shown in bold below for the screen share traffic. Media port range used for application sharing.

Used for incoming SIP listening requests for application sharing. Skype for Business Server Application Sharing service In most cases this will not be readily visible to users. You should also be aware that some fidelity/crispness of your shared content has been traded for reliability, speed, and efficiency. Please keep in mind that these numbers rely on the health and proper performance tuning of your network, and may involve networks external to your own, if your clients are on mobile devices. Works much better than RDP in low bandwidth conditions, even when sharing high motion content, such as 3-D graphics. Make the session setup and video experience faster compared to RDP alone (setup in half the time, with a 6:1 improvement in frames-per-second). Make screen-sharing (up to 5%) more reliable compared to RDP alone. Switching to VbSS aims to make three key improvements: RDP can, and will, be substituted for VbSS when the situation calls for it, so that your viewing experience won't be interrupted. Skype for Business Server uses internal logic to decide which of the two methods (VbSS or traditional screen-sharing) to apply when clients connect. If, for example, your workplace has a lot of legacy clients, RDP will still be available as a failsafe to your meetings and conversations. Since VbSS is an update to underlying technology that is used in screen sharing for Skype for Business Server, it may be difficult to detect which technology you're leveraging unless you're looking at SIP details in the network traffic, or you're sharing content that is fast moving or 3-D. Part of the goal of improving screen-sharing is that transitions between VbSS and RDP be as seamless as possible when they occur. VbSS makes use of the media platform (which relies on UDP as the underlying protocol), with the goal of improving your video start times, the viewing quality of what you're watching (especially if what you're watching is moving fast), and reliability overall.

Skype for Business Server wanted to improve people's 1-to-1, and their 1-to-many (multi-party) conversations and meeting experiences.

Newer technology, VbSS, will make use of User Datagram Protocol (UDP). Screen-sharing uses the remote desktop protocol (RDP), which is great at creating thousands of 1-to-1 sessions between people's computers. The difference between VbSS and traditional screen-sharing has to do with the underlying protocols used, and what they excel at. Video-based Screen Sharing, or VbSS, grew out of Lync screen-sharing. VbSS is included with Skype for Business Server 2019. Video-based Screen Sharing (VbSS) in Skype For Business Server 2015 is now available for download: Skype for Business Server 2015 Cumulative Update KB3061064.
