Skype for Business Unleashed Alex Lewis, Pat Richard, Phil Sharp, Rui Young Maximo. When you connect from a Mac using OS X Mavericks or OS X Yosemite to another computer using file sharing. Windows computers and Macs can then see your computer on the local network. To enable File Sharing on your Mac, open the Sharing pane of System Preferences and select the option for File Sharing. How To Share One Window In Skype For A Mac.General Methods of Controlling BandwidthI'm finding with the current RDP-based screen sharing my MacBook Pro 13' 2016 heaves - even the keyboard is slow to respond, unlike screen sharing in Skype Personal, WebEx, Google Remote Desktop, Team Viewer, VNC, SplashView, etc. Armed with that information, the next logical progression of this blog series continues the focus on application sharing and discusses the available methods within Skype4B to manage and control the bandwidth requirements for application sharing. In a previous blog post I talked about how administrators and architects should place more emphasis on planning for application sharing bandwidth in their Skype4B deployments.Share Sreeen Using Skype For Business Mac Is Only. Both methods are not mutually exclusive and can be used in concert with one another, but it is largely up to network engineers and the application engineers to work together to find the best solution for your environment.Aside from the quality of the video, it wont be obvious whether the presentation is using VbSS or RDP. Speaking broadly, there are typically two methods of controlling any sort of application bandwidth across enterprise networks. I'm hoping with VbSS, the SfB Mac developers will offload.
Vbss For Skype Sharing How To Share OneOver 100 million people are using Skype for Business to communicate for work. QoS is typically seen in two forms:MAC OSX client device - HDX RealTime Media Engine 2.4 install. This is most generally referred to as Quality of Service (QoS). Like controlling traffic on highways via “normal lanes” and “HOV lanes”, network traffic is separated, classified and handled in a manner that is configured by the network engineers to give preferential treatment (and bandwidth) to high priority traffic while giving normal treatment to non-priority traffic. In Microsoft Skype for Business Server 2019, when a Skype for Business on Mac client user tries to add a new participant to a peer-to-peer call that has a screen sharing by using the Video-based Screen Sharing (VbSS) feature, you may find the escalation fails and the participant can't receive the meeting invitation to join the peer-to-peer session.For most of the network engineers out there, this is the “preferred method”. The recipient will Symptoms. ![]() The only built-in method to control application sharing bandwidth is via the Conferencing Policies within Skype4B. Skype4B offers both of the configurations above and can be configured for one or both to suit the needs of the enterprise network.Limit Application Sharing Bandwidth Within On-Premises Skype4B Conference PoliciesThis method is by far the easiest option to limiting application sharing bandwidth within Skype4B. How does Skype4B fit in?In almost all enterprise deployments, architects and engineers desire to identify the traffic produced by Skype4B and fit that traffic within the available enterprise network configurations. While undoubtedly easy to deploy, this method has no awareness of other traffic around it and no integration with network devices that send/receive traffic, which results in a more limited “one-size-fits-all” approach. Think of this as the “ honor system” where some type of built-in application configuration tells the application to limit itself to X bandwidth when utilizing the network. In addition to the work required, as more and more applications move to SaaS available across the Internet, QoS is lost as the traffic leaves the corporate network and moves across the Internet which restricts QoS from being available from end-to-end.Control the traffic through the applicationFor most of the application engineers out there, this is the “preferred method”. Image burn software for macThe biggest current limitation is that the AppSharingBitRateKb parameter is handled per-user and only is applicable to the presenter. As a result, you can limit users in a low bandwidth site to a low bitrate while allowing users in high bandwidth sites to a higher bitrate.Set-CsConferencingPolicy –Identity Global –AppSharingBitRateKb 1000New-CsConferencingPolicy –Identity TestPolicy –AppSharingBitRateKb 1000While the second option above is my preferred option for handling bandwidth natively within Skype4B, it does come with limits. Create a Site or User policy – this approach allows flexibility in deployment by tailoring bandwidth requirements to a per-site or a per-user basis. As a result, you may limit users to an artificially low bandwidth in certain sites that have sufficient bandwidth. Alter the Global policy – while this approach is easiest, it will impact all users that don’t have a site or user policy assigned to them. Microsoft pre-creates and manages all conferencing policies within Skype4B Online and as a result you cannot create new policies or edit existing ones. In scenarios where there are Lync for Mac clients I would strongly suggest only using the Optimal numbers referenced in my previous post for the AppSharingBitRateKb setting.Limit Application Sharing Bandwidth Within Skype4B Online Conferencing PoliciesSadly, this is a bit of a bait-and-switch option because it really isn’t an option at all. Interestingly enough, the low value doesn’t seem to impact Windows-based clients but users on Lync 2011 for Mac would report that application sharing was largely unusable. Also of note is that this AppSharingBitRateKb behavior is applied both in P2P calls and within multiparty calls.Impact of this approach with Lync for MacThrough several of my deployments I’ve noticed there seems to be a significant difference with RDP performance on Mac OS clients, especially the Retina display models, when the AppSharingBitRateKb setting is reduced to a low value. When you add in the possibility of multiple users sharing desktops between the two sites, oversubscription of the 1.5 Mbps circuit becomes a very real risk. With Site A limited to 1.5 Mbps, that could result in 67% of available bandwidth being consumed for a single desktop share. The overall process of doing so consists of: The pre-requisite to all of this is that individual port ranges must be specified first. If bandwidth restrictions are required in Skype4B Online deployments, you must begin to examine QoS restrictions for each modality.Limit Application Sharing Bandwidth for On-Premises Skype4B Deployments through QoSThere are a number of articles on the Internet that already talk about this overall process but it boils down to telling the Skype4B client to utilize certain port ranges for each modality and then configuring client/network devices to treat each modality in a certain way by dedicating queues (loosely equal to bandwidth) for each network hop. For all intents and purposes, the application sharing bandwidth is not restricted for Skype4B Online deployments so architects and engineers should carefully plan your network ingress/egress points to ensure sufficient bandwidth is available. Since the Mediation Server handles all traffic to/from IP-PBXs and the PSTN, be very careful reducing the port numbers. Configure port ranges for Mediation Servers – Remember that the audio port range should be unique and not overlap any other server port ranges, such as video or application sharing. Best practices should be observed here and stick as closely to what Microsoft puts on TechNet. Since MCUs handle modalities from multiple clients be very careful reducing the port numbers to a small number of ports per modality. Configure port ranges for the MCUs – Remember that each port range should be unique and not overlap. Additionally, you should have 20 ports per modality. If switches aren’t configured for mls qos trust dscp, then DSCP markings will be stripped and classification is lost. Mark DSCP utilizing Group Policy based QoS policies on Windows clients and servers – This method is typically easiest but requires that access-layer switches trust DSCP markings coming from the endpoints. With individual port ranges in use, architects can then begin to classify the traffic using QoS using two main methods:
