About This Network Configuration Example

This Network Configuration Example (NCE) describes how to setup application affinity to primary and secondary wired links on branch SRX Series Services Gateways. If the performance of the primary link drops below the acceptable levels as specified by the SLA, traffic switches to the secondary link. When both the primary and secondary links fail, an additional backup LTE connection restores the Internet connection using the cellular wireless network.

The benefits of this use case include optimized quality of experience in a cost-efficient setup.
