Latency Tolerance

    Question

  • Is there any limitation in the SCCM package distribution if the WAN link is slow. What is the latency tolerance in SCCM for a distribution to the client.

  • Content acquisition by clients is in one of two ways: SMB and BITS. It's up to those protocols to be latency tolerant which to my knowledge, both are. BITS will handle stops and starts better as well as reconnections from alternate locations, from SMB is a tried and true protocol used by nearly everyone to do every type of file transfer possible over all kinds of links.

    What's your use case or scenario that you are trying to determine feasibility for?

    If you have more than a few clients across a WAN link, you should consider adding a BDP or a secondary site with a DP.

  • Thanks for the update Jason.

    We're looking at an option for satellite in some very very remote ATM locations. Expectation would be 800 ms round trip.

    Will distribution work on a such a slow speed link?

    Thanks

  • It's obviously going to take a while to get the content to the client, but sure it'll work. If these are single clients, definitely make sure that you use BITS-enabled DPs.
