Extransit Mobile Interaction Suite has built in support for multi user applications. By using Strike Server group triggers, multi user games and application can be developed using any type of traditional web framework or scripting language.

The Strike Server handles all over the air communication, keeping all connected clients with their latest updates.

Built-in sophisticated mechanisms can detect data changes, and update the client with the data that have changed, and only when changes have occurred. Thus, the mobile clients does not have to “poll” the server on a regular basis, which is the case with ordinary web browser solutions. This gives a great save of data over the network, as well as making the response quicker for applications with real-time characteristics, such as chat-boards etc.

The Strike Server in turn, can however poll the back-end applications for data changes on a regular basis, by using recurring processes in the flow controller.

A major difference between polling from the Strike Server middle-ware, and polling from the mobile client (which is the case with browser solutions) is that the Strike Server and back end application can reside on the same local network, where traffic is no issue, and, that the server can compare the results from subsequent polls, and transfer the differences only to the client, saving a lot of “air traffic”.
