Configuring Performance Goals

 

To configure the performance goals of a network service:

  1. Click Home> Requests > New Request .
  2. Enter the request information and click Next.
  3. In the Goals pane, click Add Goal.

    The New Goal window is displayed.

  4. Configure the goals according to the guidelines provided in Table 1.Best Practice

    Adding one or more goals to the request enables you to track performance of those parameters when you design a network service for the request. Although adding goals is not mandatory, we recommend that you do so.

  5. Click Save.

Description

Session

Goal Value

Specify the target value for the goal. When you design a network service, the goal value is used by the Network Service Designer to evaluate how your design meets the goal. There is no upper limit. As a guideline, typical achievable values for a firewall are as follows:

  • Session: 25,000–60,000 Min. of path

  • Bandwidth: 185–240 Mbps

  • Latency: 2–6 ms

  • License Cost: 100 USD

Acceptable Value

Specify a value that is lower than the target and acceptable for the network service. When you design a network service, the acceptable value is used by the Network Service Designer to evaluate how your design meets the goal.

Example:

  • Session: 20,000 Min. of path

  • Bandwidth: 150 Mbps

  • Latency: 5 ms

  • License Cost: 99 USD

Must Value

Specify the minimum value for the goal. The minimum value should be lower than the acceptable value. When you design a network service, the must value is used by the Network Service Designer to evaluate how your design meets the goal.

Example:

  • Session: 15,000 Min. of path

  • Bandwidth: 100 Mbps

  • Latency: 4 ms

  • License Cost: 95 USD

Based on

View the method that is used by the Network Service Designer to evaluate how your design meets the goal. You cannot edit this field.

Example:

  • Session: Min. of path

    If there are multiple VNFs in the service chain, then the VNF with the smallest bandwidth is chosen.

  • Bandwidth: Min. of path

  • Latency: Cumulative

  • License Cost: Cumulative

Unit

Specify the measurement unit of the goal.

Example:

  • Bandwidth: Mbps, Gbps

  • Latency: ns, ms

  • License Cost: USD
