Device-to-Platform Communications

Depending on your environment, devices can connect to either a Relay Server deployed to the DMZ (recommended), or to Unwired Servers directly deployed to the DMZ. In the former case, the Relay Server is the first line of defense to the Platform by acting as a proxy for the device and facilitating interactions with Unwired Servers installed on the corporate LAN.

Relay Server connections — The traffic content depends on the payload protocol of the application:
- Messaging communication encrypts the entire communication stream with a proprietary protocol.
- Replication use an HTTP or HTTPS protocol which can optionally be encrypted end-to-end via TLS.
For Relay Server, configure the Web server host (IIS or Apache) to use a secure port, and use Sybase Control Center to configure Relay Server to use secureprotocols, ports, and certificates in Sybase Control Center.

On the client (in the case of mutual authentication), install certificates, and configure profiles to connect to Relay Server.
Unwired Server connections — The traffic content also depends on the payload protocol of the application:
- Messaging communication uses an fully encrypted end-to-end with a proprietary protocol.
- Replication use an HTTP or HTTPS protocol.
