This topic defines the set of network performance requirements for Skype for Business Online services and how you can choose to use the Internet or Express. Route for connectivity between your network and Skype for Business Online based your assessment of the network connectivity. If you have decided to deploy Azure Express. Route for dedicated connectivity to Office 3. Express. Route connections in different Skype for Business Online deployment scenarios.
The quality of Real- Time media (audio, video, and application sharing) over IP is greatly impacted by the quality of end- to- end network connectivity. For optimal Skype for Business Online media quality, it is important for you to make sure there is a high- quality connection between your company network and Skype for Business Online. The best way to accomplish this is to set up your internal network and cloud connectivity based on the capacity of your network to accommodate for peak traffic volume for Skype for Business Online across all connections. Azure Express. Route isn't a requirement for Office 3. Skype for Business Online. However, Azure Express. Route is one of the deployment options that are available that will help make sure that connectivity to Office 3. Skype for Business network performance requirements and ensures the most optimal Skype for Business Online media quality experience. Tip: Although this topic provides you with overall networking performance guidance, complete guidance for network assessment is outside of the scope of this document.

Factors that impact Skype for Business Online media quality. There are many different factors that contribute to Skype for Business Online Real- Time media (audio, video, and application sharing) quality that include the devices that are used, the environment, and the network connectivity. Devices. In a Real- Time media session, media capturing and rendering devices that are used by all participants such as headsets and Web cams have a great impact on the overall audio and video quality. Lower quality devices or devices with incorrect device drivers will produce lower overall sound quality for audio and lower image quality for video. Certified devices or good quality devices, on the other hand, help with echo cancellation, noise filtering, video resolution and reduce latency. Although certified audio and video media devices aren’t required, it’s highly recommended devices certified for Skype for Business for the most optimal media experience. For a list of all Skype for Business certified devies, see Phones and Devices for Skype for Business. You can use the Skype for Business Online Call Quality Dashboard, found in the Skype for Business admin center, to verify devices in use are working correctly and monitor audio and video media quality. Tip: A certified device is required for the most optimal Skype for Business media quality experience. The device and software processing latency, along with network latency, have a great impact on and contribute to the end- to- end overall latency and the end user’s experience. Environment. The environment and surrounding area where users are meeting and using audio and video devices is another big factor for audio and video quality. Users calling from a noisy environment will have echoed, muffled and unclear audio. Users in a dark or low light environment won't be able to produce bright, clear image quality for video. In a conference room setting, the location of the microphone and video device have a direct impact on the sound and image quality that participants will receive. To get a clearer picture of a user’s audio and video experience use the Skype for Business app Tools > Options > Audio Device or Video Device to make changes to the device in use and customize it's settings. You can also check the audio quality of a call by clicking Check Call Quality. If they click Check Call Quality, they can then report the quality and issues found with the test call. Network. The quality of the Real- Time media over IP network is greatly impacted by the quality of the network connectivity, but especially by the amount of: Latency This is the time it takes to get an IP packet from point A to point B on the network. This network propagation delay is essentially tied to physical distance between the two points and the speed of light, including additional overhead taken by the various routers in between. Latency is measured as one- way or Round- trip Time (RTT). Packet Loss This is often defined as a percentage of packets that are lost in a given window of time. Packet loss directly affects audio quality—from small, individual lost packets having almost no impact, to back- to- back burst losses that cause complete audio cut- out. Inter- packet arrival jitter or simply jitter This is the average change in delay between successive packets. Most modern Vo. IP software including Skype for Business can adapt to some levels of jitter through buffering. It’s only when the jitter exceeds the buffering that a participant will notice the effects of jitter. Note: Buffering for jitter will increase end- to- end latency. With many concurrent Skype for Business Online Real- Time media sessions, as well as other network traffic generated by other Office 3. Skype for Business Online service is critical to avoid network congestion and ensure excellent media Real- Time media (audio, video, and application sharing) quality. Implementing Quality of Service (Qo. S) across congested networks. In addition, traffic congestion across a network will greatly impact media quality. To allow audio and video packets to travel the network quicker and to be prioritized over other network traffic in a congested network, Quality of Service (Qo. S) can be used to help provide an optimal end- user experience for audio and video communications. Qo. S provides a way for you to assign higher priorities to network packets that are carrying audio or video data. By assigning a higher priority to these packets, audio and video communications are likely to travel over the network faster, and with less interruption, than network sessions involving things like file transfers, web browsing, or database backups. That's because the network packets used for file transfers or database backups by default are assigned . If you don’t assign a higher priority to the media (audio, video, and application sharing) packets and leave them also assigned as “best effort”, they too will be processed along with all other network traffic. Depending on the amount of network congestion, this will potentially end up in a lower overall audio and video quality experience for your users. It is highly recommended that you implement Qo. S on your network to make sure that network congestion within your network won't have an impact. However, for this to have the maximum impact, all networking endpoints must support Qo. S, meaning that all endpoints must honor Qo. S marking and packet prioritization. Skype for Business Online services honor Qo. S marking and prioritization within the Microsoft network. However, traffic that is routed across a public connection like the Internet from your company network to the Microsoft network doesn’t preserve Qo. S markings and packet prioritization. Private connections from your network to Office 3. Azure Express. Route offer a deployment solution that preserves Qo. S markings and packet prioritization that will in turn increase overall audio and video quality for your end users. Network performance requirements to connect to Skype for Business Online.
