A gateway is a mechanism used to send push notifications. They are an alternative to light weight pollers and require a constant network connection.
Gateway properties are configured on a MobiLink server. You can configure multiple gateways on a single MobiLink server. See MobiLink server settings for server-initiated synchronization.
The following gateways are supported on the MobiLink server:
SYNC gateway The SYNC gateway is a TCP/IP-based gateway; push notifications are sent through the same protocol as your MobiLink synchronizations.
The default SYNC gateway is named Default-SYNC. Typically, the default gateway settings do not need to be changed.
UDP gateway The UDP gateway sends push notifications through a UDP gateway.
The default UDP gateway is named Default-UDP. Typically, the default gateway settings do not need to be changed. Listeners use UDP by default when listening for push notifications.
SMTP gateway The SMTP gateway sends push notifications using an email-to-SMS carrier service.
The default SMTP gateway is named Default-SMTP.
In addition to the supported gateways, you can configure a device tracking gateway which automatically chooses the most appropriate gateway to send push notifications. The default device tracking gateway is Default-DeviceTracker. It is recommended that you use this gateway if you do not want to use a light weight poller. For more information about device tracking, see Device tracking gateways.
