Distributing outgoing traffic over multiple links

The following example illustrates NetCache configuration and the use of policy routing to split HTTP traffic over outgoing links.

You need to configure each NetCache appliance so that the IP addresses of its network cards show different source addresses. You can then set up your policy routing so that the traffic from NetCache can be split over multiple links.
In this example, an L4 or L7 switch is deployed on the network to balance client traffic over the NetCache appliances. However, if the NetCache appliances were directly connected to the router in your deployment, you would set up source IP addresses on the NetCache appliances and policy routing on the router the same way as in this example.
This example shows multiple routers to make it easier for you to see that there are multiple links. This is not meant to imply, however, that you must have multiple routers to be able to split outgoing traffic over links.
