Secure Unwired Platform component communications to prevent packet sniffing or data tampering. Different combinations of components communicate with different protocols and different ports.
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.
Unwired Server and Data Tier Communications
Unwired Server uses two synchronization databases for its data tier: one for replication and one for messaging. It also connects to a cluster, monitor, and domain log database.
Unwired Server and Sybase Control Center Communications
There are two different communication streams used to communicate with the Sybase Control Center administration tool: one for communications with the Sybase Control Center web console, and one for the communications with the Sybase Control Center X.X Windows service.
Unwired Server and EIS Communications
Secure communication between Unwired Server and any supported backend depends on the direction of the interaction between these components.
Unwired Server Nodes in Production Cluster Communications
(Not applicable to Online Data Proxy) Unwired Servers communicate with other Unwired Servers in the same cluster differently, depending on the type of communication performed.
