About path selection
You configure path selection under Networking > Network Services: Path Selection.
Path selection ensures the right traffic travels the right path, by choosing a predefined WAN gateway for certain traffic flows in real time, based on availability. You define a path, called an uplink, by specifying a WAN egress point and providing a direction for the egressing packets to take. This granular path manipulation enables you to better use and more accurately control traffic flow across multiple WAN circuits.
A common use of path selection is to route voice and video over an expensive, high-quality, multiprotocol label switching (MPLS) link, while offloading less time-sensitive business traffic over a less expensive internet VPN or direct internet link. Enabling internet paths makes efficient use of existing resources by taking advantage of both private and public links. Using path selection provides the right performance levels for your applications and saves on bandwidth costs by optimizing the use of available bandwidth.
The path selection WAN egress control:
• is a transparent operation to the client, server, and any networking devices such as routers or switches.
• identifies and processes both optimized and pass-through traffic.
• supports single and multiple firewalled paths.
• is compatible with all transport modes, including fixed-target configuration.
• can be used to encrypt traffic using the secure transport service.
The SteelCentral Controller for SteelHead is required to configure path selection with the secure transport service. You cannot configure path selection with the secure transport service from the Edge. For details, see the SteelCentral Controller for SteelHead User Guide and the SteelCentral Controller for SteelHead Deployment Guide.
