To create a traffic profile in Cable mode:
- From the Policy Server section of the navigation pane, select Traffic Profiles.
The content tree displays a list of traffic profile group; the initial group is ALL.
- Select the Traffic Profiles group.
The Traffic Profile Administration page opens in the work area and lists available traffic profiles.
- Click Create Traffic Profile.
The New Traffic Profile page opens.
- Enter the Name for the traffic profile.
The name can only contain the characters A–Z, a–z, 0–9, period (.), hyphen (-), and underline (_). The maximum length is 255 characters.
- Select the Traffic Profile Type from the list.
The types of traffic profiles available depend on the mode in which the CMP system is operating. Cable Mode contains the following traffic profile types:
- Best Effort (default) — Transmission opportunities are granted on a first-come, first-served basis. Appropriate for upstream service flows such as Web browsing, e-mail, or instant messaging.
- Diameter QoS — a policy and charging control rule.
- Downstream — Defined through a similar set of QoS parameters that are associated with the best-effort scheduling type on upstream service flows. Appropriate for all downstream service flows.
- Non-Real-Time Polling — Cable modems are polled at a fixed interval for queued data. Appropriate for upstream service flows that require high throughput, and traffic that requires variable-sized data grants on a regular basis, such as high-bandwidth FTP.
- RSVP Flow Spec — Receivers initiate reservation requests for unidirectional data flows, and senders respond with path information.
- Real-Time Polling — Cable modems are polled at a fixed but short interval for queued data. Appropriate for upstream service flows of real-time traffic that generate variable-sized data packets on a periodic basis and have inflexible latency and throughput requirements, such as MPEG video.
- Service Class — The profile will use a service class that is configured on the CMTS.
- Unsolicited Grant — A fixed-size grant is offered to service flows at fixed intervals without additional polling or interaction. Appropriate for upstream service flows of real-time traffic that generate fixed-size data packets on a periodic basis, such as VoIP.
- Unsolicited Grant with Activity Detection — When there is activity, the CMTS sends unsolicited fixed grants at fixed intervals to the cable modem. When there is no activity, the CMTS sends unicast poll requests to the cable modem to conserve unused bandwidth. Appropriate for upstream service flows that include silence suppression.
- Select to Enable Dynamic Override (available for Diameter QoS profiles).
If you select this option,
Dynamic Value fields are displayed for configuration parameters. You can enter variables for the configuration parameters. Variable names must be enclosed in curly braces ({}). For more information about dynamic overrides, see
About Traffic Profile Variables.
- Enter the parameters for the selected Traffic Profile Type.
The set of fields displayed on the Traffic Profile page varies depending on the Traffic Profile Type you select.
The following list details the configuration parameters for traffic profile types:
- Click Save.
The traffic profile is defined in the CMP database and can now be used in a policy.
