> # Network Tab of the Replication Agreement Dialog

> The settings on this tab control how the replication mechanism will use the network when sending updates to this replica.

> The default settings are optimal in most cases, but you may need to adjust them in certain cases such as replication over wide area networks (WANs).

> Window size. This value determines the maximum number of updates messages that can be sent without immediate acknowledgement from the consumer. The properties of networks make it more efficient to send more messages at once instead of waiting for an acknowledgement to be returned after each one.

> Group size. This value determines the maximum number of data modifications that can be bundled into a single update message. Depending on the size of your data and the properties of your network, it might be more efficient to send larger messages, and thus have a larger group size.

> The group size must be smaller than or equal to the window size.

> Description. Use this optional field to modify the short description of this replication agreement. This description will appear beside the consumer hostname in the list of agreements for this replica.
