I believe you all are doing good. Finally we have some relief from pandemic and entering festive season. Hope all be good from here, finger crossed 🙂
In this post we will discuss about peer cache technologies from Microsoft mainly in reference to CM. This is very relevant as Windows 11 is already at door and anyways large feature and other updates are bottleneck for low bandwidth locations. These are number of Microsoft technologies which can help in these situations and already detailed blogs are on internet covering them. In this post we will discuss their comparison and limitation. This will give a picture abut how to use them in combination for effective solution.
These technologies can be of two types:
- Bandwidth management
- Peer to Peer Sharing
|Technology||Bandwidth Management||Peer-to-Peer sharing|
Lets discuss these technologies in terms of features.
|Features||Peer Cache||Branch Cache||Delivery Optimization|
|Support multiple subnets||Yes||No||Yes|
|Bandwidth throttling||No (Bits dependent)||No (Bits dependent)||Yes|
|Peer Discovery||Through Management Point||Broadcast||DO Cloud service|
|Peer cache discovery||Manual (Client settings)||Automatic||Automatic|
|Distribute CM content||All CM content||All CM content||Windows updates, drivers, store apps|
|Distribute Intune content||No||No||Yes, for Windows update|
|OS deployment – PXE||No||No||No|
|Wake on peers for content||No||No||No|
|CM content pre-caching||Yes||No||No|
|Share content while downloading||No||Yes||Yes|
|No need of CM boundary group||No||Yes||Yes|
BITS is used by Branch Cache and Peer Cache for bandwidth throttling but it works on available bandwidth at local adapter. Hence it has no sight of end-to-end network bandwidth and can increase congestion in few cases.
LEDBaT is another solution for bandwidth throttling and can be enabled on Distribution points. But it has minimum OS requirement for DP. Also it runs at server side and client side throttling is not possible.
As we can see that all these technologies have few limitation so Microsoft recommends to use combination of them.
DO+ Branch Cache + Peer Cache
That’s all in this post. Hope you enjoyed the content and till the time we meet with some other technical content, take good care of yourself.
