| - | ======Description and cases====== | ||
| - | The SSG can act as a traffic balancer based on IP addresses belonging to an AS defined as '' | ||
| - | In this case, the SSG-LB acts as an L2-bridge in the network, hence the name L2 traffic balancer. | ||

| - | =====Case: Balancer on a traffic mirror===== | ||
| - | Suppose a 400Gbps traffic mirror needs to be evenly distributed among four VAS platforms (Value-Added Services) performing traffic analysis and various detection.\\ | ||
| - | In this case, SSG-LB will evenly distribute traffic with equal port utilization on the pullers and maintain traffic symmetry (traffic from one session will be directed to only one puller). | ||
| - | {{ : | ||
| - | **Example configuration / | ||
| - | * Traffic mirroring is fed into 4x100G interfaces. | ||
| - | * Traffic is balanced between four pullers, each puller is connected by 4x25G links. | ||
