Load Balance

Configuring Load Balancing	Figure 7. Load Balance Console
The Twin WAN line of products uses a session based Load Balancing algorithm by allowing you to
manage sessions using several different options:

Bytes rx+tx By monitoring real time speed of both WAN connections, the XC-DPG603 will establish new sessions on the WAN port with the lower speed. Use this if there is a fairly even speed on both lines and would like to benefit the most from the speed available.

Packets rx+tx Same as above but in this case, the XC-DPG603 monitors the packet flow and tries to maintain an even number of packets. Use this if transmitting a lot of small packets, such as web browsing and Usenet. This helps you maintain the best latency.

Sessions Established

The XC-DPG603 tries to maintain an even number of sessions on each WAN port by looking at the current amount of sessions currently established. This is a very general setting only to be used if you have similar types of connections (Cable and Cable, DSL and DSL) to promote good Internet traffic.

Settings - Load Balance

Load Balance	• Enable – Use this to enable your Load Balance settings.
Configuration	• Balance Type – Select the desired Balance Type:
	- Bytes rx+tx – Traffic is measured by Bytes.
	- Packets rx+tx – Traffic is measured by Packets.
	- Sessions established – Traffic is measured by Sessions.
	• Loading Share on WAN 1 – Enter the percentage (%) of traffic to be sent over WAN 1. The WAN port with the greater bandwidth should
	be given a higher percentage of traffic over the other WAN port.
	Click the “Update” button to save your changes.
NAT Statistics	This section displays the current data about WAN 1 and WAN 2. You can use this information to help you “fine-tune” the settings above.
Interface Statistics	This section displays cumulative statistics.
	Use the “Restart Counters” button to restart these counters when required.
Buttons	• Update – Save the settings on this screen.
	• Refresh – Update the data on screen.
	• Restart Counters – Restart the counters used in the “Interface Statistics” section.
