Sync Services for ADO.Net on a low bandwidth (2.4 kpbs)? RRS feed

  • Question

  • Hi,

    Is it possible to sync between central database and its client on a 2.4 kbps internet connection?

    Or likely that the connection will 'die' during the following process.  Hence NOTHING will actually be sync at the end of the day?

    Any help is greatly appreciated, thanks!

  • If the network is reliable (even though it is slow) and batching may help to transfer small amount during one sync.

  • Hello -

    1. Yes, you can definitely run sync over a low bandwidth network.  However it is necessary to have this network reliably connected.
    2. Is your App a 2 tier App or a N-tier App through WCF or web service?

    Thanks.

  • thanks for your response.

    1) the client database is off shore and can only use a 2.4kbs satelite phone as a modem to internet connection.
    2) the app is n-tier through wcf on shore.  off shore will host its own app and database, with the need to sync the database between on shore

    we will be proceeding to use the convention method to extract data from its database and send as email attachment to be updated on the other sides.
