Windows 10 Bandwidth Management DO Delivery Optimization with LEDBAT in LAN

I will explore Windows 10 Bandwidth Management DO Delivery Optimization with LEDBAT in LAN in this blog post. Let’s see what improvements and enhancements Microsoft has for bandwidth management. Delivery Optimization is the core technology in bandwidth management. All the screenshots are taken from Andy Rivas and Narkis Engler’s Ignite session demo.

Delivery Optimization is a feature designed to automatically adjust the network bandwidth for uploading and downloading updates, as well as for Microsoft Store apps and other Microsoft products. This feature helps optimise content delivery by using an intelligent and efficient approach to network utilization.

By dynamically adjusting the bandwidth, Delivery Optimization ensures that the network resources are utilized effectively, providing users with a smoother and more efficient experience when receiving updates and accessing Microsoft products.

Below are more details (Delivery Optimization with LEDBAT) about the session and recording in the section of this post.

Delivery Optimization with LEDBAT

Delivery Optimization is a fully cloud-managed solution, but you can have on-prem caching servers.

• Delivery Optimization (DO) is a fully supported cloud service (out of preview for very long)
• More granular configuration and throttling options are available with Microsoft Endpoint Managed (SCCM and Intune)
• More matured & stabilized with many supported scenarios for several types of content.
• I’m excited about Delivery Optimization with LEDBAT in LAN options (coming soon)

Delivery Optimization Support Enhancements

More content support scenarios are added to DO with SCCM and Intune. Some of them are given below:

• Windows Updates
  • Feature/Quality/Security
  • Drivers
• Windows Store Apps
• Microsoft Store for Business Apps
• Office 365 Pro Plus and Office 2019 UPDATES & Installation (Initial Installation – it’s a public preview)
• Xbox game pass apps (MSIXVC)
• Coming Soon
  • New Microsoft Edge installs and updates
  • MSIX Apps
  • Dynamic Updates
  • SCCM Content

Who Should Use Delivery Optimization

I like this slide presented in the Ignite. It’s very straightforward messaging from Microsoft.

• Windows Updates from the cloud – Express and Delta Updates are the ONLY supported with Delivery Optimization and SCCM.
• Office 365 ProPlus Updates – Only Hybrid/Lean updates are supported by Delivery Optimization and SCCM

IMP for SCCM Admins – Office 365 ProPlus Bandwidth Consideration Posts – Lean/Hybrid – Building dynamic, lean & universal packages for Office 365 ProPlus & Office 365 ProPlus Deployment and Proxy Server Guidance!

Real-world Example of Delivery Optimization

50% to 70% in Microsoft’s average efficiency rate experience.

Real-World Scenario

85% of data is coming from Peers using Delivery Optimization in SCCM.

Delivery Optimization Best Practices Policies

• Hubs & Spoke (Network Topology)
  • Download mode
    • DODowloadMode
  • Recommended Value:
    • 1 or 2
• Sites have more than 30 Devices (Leverage peers for more content)
  • Minimum File Size to Cache
  • DOMinFileSizetoCache
    • 10 MB
• Mobile Workforce Large Number of Laptops/Tablets (Increase the number of devices capable of uploading content)
  • Allow Uploads battery power
    • DOMinBatteryPercentageAllowedToUpload
      • 60%
• Lab with Desktop/DC Powered Devices (Dedicated Devices that can upload more content for a longer period)
  • Content Expiration
    • DOMaxCacheAge
      • Seven days up to 30 days
• Delay the use of HTTP (give opportunity for devices to find peers before falling back to cloud/CDN/On-prem Cache)
  • DODelayBackgroundDownloadFromHttp
    • 60 seconds to 30 minutes

What’s New in the DO world

• New and Expanded PowerShell cmdlets
  • For advanced cache management and troubleshooting
• New DO policies
• Nonprivate IPs (not in RF1918) allowed as LAN peers
• New GroupID Source:
  • AAD TenantID
• LEDBAT in LAN uploads/sends support with DO
  • Sixty milliseconds queuing delay – slow down the upload!
  • Alleviate concerns over WiFi router congestion with Delivery Optimization

Peer to Peer Challenge for Cloud CDN Delivery Optimization?

Challenges

• Customers who have sites with very low bandwidth need a better overall bandwidth reduction guarantee (peer to peer is opportunistic)
• Some customers use Peer Peer (All VPN WiFi networks)
• EDU customers have sites with too few devices/lots of devices on battery
• Some customers can’t push policies to devices on their network (ISPs, universities with public WiFi) but still want to reduce the bandwidth impact

The solution to work with Delivery Optimization

• SCCM and Microsoft Connected Cache Integration to Help with Bandwidth Issues
• Cloud Solution – Microsoft Connected Cache Container Instances in Azure
