Relay Server

Relay Server acts as a reverse proxy for client devices communicating with the Unwired Server cluster, and it provides load balancing for the Unwired Server cluster.

Relay Servers are deployed on the DMZ subnet. With a corresponding Outbound Enabler (RSOE), Relay Server enables communication from the Unwired Server cluster to client devices, via the Internet, without opening an inbound port on the internal firewall.

Each Unwired Server instance is supported by one or more RSOEs. Each RSOE opens outbound connections to the Relay Server, to handle both inbound and outbound communication channels, on behalf of the Unwired Server. Connections between the RSOE and Relay Server use HTTPS protocol.

Relay Server also provides load balancing for the Unwired Server cluster by forwarding requests from client devices to Unwired Servers in the cluster, by round-robin distribution.

• Configuring a Relay Server
  Choose a method of configuring a Relay Server. After you generate a Relay Server configuration file, you can copy it to the Relay Server host, and quickly distribute the same configuration to multiple Relay Server nodes, with minimal changes.
• Managing Configured Relay Servers
  Relay Servers configured with Sybase Control Center are registered in the Unwired Server cluster database. Administrators can view or edit configuration properties, and delete Relay Servers in Sybase Control Center when they are displayed in the Relay Server tab.
• Relay Server Tab Reference
  Configuration property values that appear in the Relay Server tab for an Unwired Platform cluster.
