The WAN Optimizer

The Sparx Wide Area Network (WAN) Optimizer is a lightweight server installed on a Local Area Network (LAN) connection to a Database Management System (DBMS) that hosts an Enterprise Architect repository. You can configure the server to listen for client connections on a particular port; it acts as a local proxy to execute queries and return the results in a compressed format to the client.

The WAN Optimizer significantly improves Enterprise Architect's performance in a WAN by reducing the amount of data transmitted and, in turn, the number of network calls made.

In the following diagram, transmission between Enterprise Architect and a DBMS is depicted first without and then with the WAN Optimizer.

You can download the WAN Optimizer installer from the Downloads page of the Registered Users section of the Sparx Systems website. The Wan Optimizer Service installer package provides two installable features for the target machine:

• WAN Optimizer Service - the installer also helps register and start the service on the target machine, and add it to the Windows Startup folder
• WAN Optimizer Admin Client - to enable an administrator to administer and configure the service from a remote client.

The Optimizer has its own Sparx WAN Optimizer User Guide. See that User Guide for more information on:

• WAN Optimizer Components
• Installing and Starting the WAN Optimizer Service
