Work with your network team to make sure proxies allow network traffic to bypass *. and avoid HTTPS decryption for *.Ī spike in upload traffic is expected if you deploy the Known Folder Move setting in your organization.

Make sure the connection to the service is enabled. It saves both network bandwidth and device battery life. Instead of the sync app constantly pulling to check for remote changes, WNS ensures that any changes from the cloud get pushed down to the device as fast as possible. Windows Notification Service or WNS plays an important role in efficient network utilization. It reduces the time it takes to upload and download the file as well as the bandwidth sync consumes. This makes the file synchronization process faster for these files. During everyday usage, when users change files, only the changes are uploaded or downloaded and not the whole file. Differential sync enables the sync app to sync only the parts of large files that have changed, instead of the entire file. The OneDrive sync app provides differential sync for all file types stored in OneDrive and SharePoint. The following image illustrates the network utilization over time with Files On-Demand enabled and not enabled.Īfter the initial sync is complete, the network usage will decrease and then level out.

This allows users to browse their files in File Explorer without downloading them. To avoid this spike, enable Learn about OneDrive Files On-Demand. When users download locations for the first time, bandwidth usage will spike. Initial deployment and initial sync of team sites Use the measurements from the pilot group to extrapolate the entire organization's needs and re-test to validate the estimations. To establish a group:Įstimate the number of files, typical file sizes, file types, total size of each library, how frequently files are modified, and how frequently new files are added.Įvaluate network utilization during each sync state as described below. When you create a pilot group, make sure the users are representative of the different profiles of people in your organization as well as the different geographic locations. Measure the network utilization of the sync app for a pilot group Other sync app traffic (such as checking for file changes and checking for app updates) is minimal. Therefore, the bandwidth used depends on the number of files in the user's OneDrive and in SharePoint document libraries they choose to sync, multiplied by the size of files, and then by the rate of change of any file. The bandwidth used by the sync app is predominantly file upload and download traffic and is usually closely correlated with file size and the number of files being synced. The loss and latency will likely vary based on the number of users that are on the same network and what those users are doing (like downloading or uploading large files). For example, a high-latency network or network experiencing a lot of loss could result in a degraded OneDrive upload and download experience even on high-bandwidth networks (1000 Mbps, for example). Packet loss, latency, and other factors can also impact OneDrive upload and download experience. You can use third-party speed test tools, like Wireshark or Fiddler, to understand the actual download and upload throughput that the users experience. Assess the available bandwidth and network conditions When you deploy, Control sync throughput.

Measure the network utilization of the sync app for a pilot group. Each installation multiplies the bandwidth used, so a user who has three syncing computers uses three times the bandwidth as a user who has a single syncing computer.Īssess the available bandwidth and network conditions. Estimate the network bandwidth you need in your organizationįollow these steps to estimate the bandwidth that will be used when you fully deploy the sync app.Īssess the number of users and computers per user to which you'll deploy the sync app. If you're not an IT admin, follow the steps in this article to limit the network bandwidth used for syncing your files: Change the OneDrive sync app upload or download rate. This article is for IT admins planning to deploy the OneDrive sync app and wanting to estimate the network bandwidth users will need for syncing.
