Configuring an SLA Profile

An SLA profile defines a threshold value for path performance indicators such as latency, jitter, packet loss, and uplink utilization. To determine if the path meets the performance criteria, Branch Gateways use the loss, latency, and jitter information fetched from the HTTP Hypertext Transfer Protocol. The HTTP is an application protocol to transfer data over the web. The HTTP protocol defines how messages are formatted and transmitted, and the actions that the w servers and browsers should take in response to various commands. probes. Branch Gateways determine the optimal path that meets the criteria defined in the SLA profile for the SaaS application.

To set SLA parameters for a SaaS application profile, complete the following steps:

  1. In the WebUI, set the filter to a group that contains at least one Branch Gateway.

    The dashboard context for a group is displayed.

  2. Under Manage, click Devices > Gateways.

    A list of gateways is displayed in the List view.

  3. Click the Config icon.

    The gateway group configuration page is displayed. The SaaS SLA profile configuration is available in the Advanced Mode.

  4. Click WAN > SAAS Express.

  5. Click SLAs. By default, the Branch Gateway includes the BestForSaas exit profile.
  6. To add a new SLA profile, click + in the SLAs table.

  7. Configure the following performance indicators:

    • Name—Name of the service. By default, BestForSaaS is selected.
    • Loss %—To measure packet loss. You can set a specific percentage of packet loss allowed for the traffic type.
    • Latency (ms)—To measure the round-trip ping time. You can set a threshold value in milliseconds.
    • Jitter (ms)—To measure if the packets are delivered in an appropriate order. You can set a threshold value in milliseconds to observe jitters in packet transmission.
    • Utilization%—To measure the percentage of bandwidth utilization. You can set a specific percentage of bandwidth utilization as a metric to prioritize and load-balance the traffic.
