WISEflow is a SAAS solution which in general requires a stable internet connection to interact with. Besides file up- and download of assignments and submissions, which are determined by the usage of the user/institution, WISEflow itself is rather lightweight in terms of bandwidth requirements; as low as 5/1 Mbit would be feasible.
FLOWlock and FLOWmulti
Certain tools in WISEflow are based on single page functionality, which allows for lower requirements on network connectivity. The most important ones are onsite exam flows based on FLOWlock or FLOWmulti. On those flow types, internet connection is only absolutely required on the time of the launch of the lock down browser. When first the flow page has been initiated within the lock down browser, it can show the assignment and allow for the participant to complete the flow even though the internet connection is temporarily or fully missing. Fallback measures with encrypted local file backups are built-in features that ultimately lets the participant submit his works with a secured file upload after the flow has ended.
Some extra features in FLOWlock/FLOWmulti though are not possible to maintain in a working state if the connection is not present, such as provided external internet resources or the generation of appendix material in the appendix manager.
