Warning

Modifying any attribute of an activated SWe Traffic Profile is service-impacting because all VMs constituting the redundancy group (1:1 or N:1) will reboot simultaneously. 

Ribbon recommends only modifying unactivated custom profiles. For standard profiles, only the codec profile names are editable.

This object is accessible only in SBC SWe environments.

Note

Changing any parameters of an activated SWe Traffic Profile changes the SWe VM CPU and memory requirements. Use the SWe Capacity Estimator tool to understand the implications of these profile changes.

Use this window to view or create SWe traffic profiles. The performance of the SBC SWe VMs can be optimized by providing the anticipated call mix as part of configuring the SBC SWe instance. The call mix is conveyed through a traffic profile which includes factors such as the amount and type of transcoding anticipated. The SBC includes a set of predefined call mixes in its standard traffic profiles. You have the option to create a custom traffic profiles with a call mix that is more suitable for your environment. You can have a maximum of 20 profiles in the system.

To View SWe Traffic Profiles

On the SBC main screen, go to All > System > Swe Traffic Profiles. The Swe Traffic Profiles window opens showing the standard profiles and any custom profiles you created.

Swe Traffic Profiles

To Create a SWe Traffic Profile

On the Swe Traffic Profiles window:

  1. Click New SWe Traffic Profiles. The Create New Swe Traffic Profiles window opens.

  2. Use the following table to enter the profile parameters and click Save.

    ParameterLength/RangeDescription
    Name1-40 characters

    Enter the SWe Traffic Profile name. 

    The Swe Traffic Profiles List window includes several standard profiles, such as: 

    • default – By default, non-cloud instances are assigned the default profile. This profile retains the SBC SWe behavior of earlier releases (5.0.x and 5.1.x), where signaling and media vCPUs overlapped.
    • standard_signaling_profile – This profile utilizes the vCPUs for signaling (direct media) calls. It is assigned by default on cloud-based S-SBC instances.
    • standard_passthrough_profile – This profile utilizes the vCPUs for pass-through calls.
    • standard_transcoding_profile – This profile utilizes the vCPUs for transcoded calls.
    • standard_callmix_profile – This profile supports call mix which contain a combination of 90% pass-through and 10% transcoding calls.
    • standard_msbc_profile – The purpose of this profile is to utilize the vCPUs primarily for pass-through calls. This profile gets auto-configured on cloud-based M-SBC instances.
    • standard_highcps_callmix_profile – This profile is similar to standard pass-through profile with higher CPS.
    Call Hold Time10-10800Enter the average call hold time, in seconds, of the call load for this profile.
    Is AccessN/A

    Set this flag to "True" to specify whether the deployment uses an access scenario.

    • False (default)
    • True
    Bhca Per Subscriber0-5

     Indicates the number of Busy Hour Call Attempts (BHCA) to use per subscriber.

    NOTE: This parameter is available when Is Access = "True."

    Internal Refresh Timer15-86400

    The internal registration refresh time, in seconds, towards the AS. 

    NOTE: This parameter is available when Is Access = "True."

    External Refresh Timer15–86400

    The external registration refresh time, in seconds, towards the AS.

    NOTE: This parameter is available when Is Access = "True."

    Direct Media Percent

    0-100

    The call load percentage for direct media. The SBC does not convert Direct Media to pass-through calls.

    The default value is 0.

     NOTE: Ensure that the combined total percentage of Direct Media Percent and Transcode Percent does not exceed 100%.

    Transcode Percent0-100The percentage of call load to use for transcoded calls.
    Passthrough Codec ProfileN/A

    The name of the codec mix to associate with the Passthrough Codec Profile.

    • G711_20ms
    • G711_G729_20ms
    Transcoding Codec ProfileN/A

    The name of the codec mix to associate with the Transcoding Codec Profile.

    • G711_20ms
    • G711_G729_20ms

    NOTE: This option does not appear until the Transcode Percent value is greater than 0.

    Crypto Percent1-100 

    The percentage of media sessions (including both transcoding and pass-through) requiring cryptographic treatment. The value is 50 when there is SRTP<->RTP interworking on all calls.

    Tone Percent 1-100Use this parameter to specify the percentage of legs to use for tones treatment.
    Processor Capability Index OverrideN/A

    Use this flag to enable/disable index overriding of the default CPU performance computation by the SBC SWe. When set to 'True', the computed indices (which are calculated during system boot-up) are ignored, and the value provided in the Processor Capability Index Override Value attribute is used for all estimations.

    • False (default)
    • True 
    Processor Capability Index Override Value0.2-10

    Use this parameter to specify the computational value to use to override the default computed indices. (default = 1)

    NOTE: This parameter is available when Processor Capability Index Override is set to "True". 

    Use GPUFor Transcoding

    N/A

    Use this flag to specify the type of transcoding. 

    • False (default) – GPU
    • True – CPU
    Sig Cost Factor0.0001-100Use this parameter to specify a signaling cost factor to use during capacity estimation. This factor affects the signaling plane estimation, such as CPS estimation (default = 1). This parameter is applicable only to custom profiles.
    Media Cost Factor0.0001-100 Use this parameter to specify a media cost factor to use during capacity estimation. This factor affects the media plane estimation, such as crypto session and pass-through session estimation (default = 1). This parameter is applicable only to custom profiles.
    Tx PPSFactor1.0 to 100 Use this parameter to specify a transmitted (Tx) PPS factor to use during capacity estimation. Use the Rx/Tx parameters for scenarios such as SIPREC where the received/transmitted PPS may not be the same (asymmetric) (default = 1). This parameter is applicable only to custom profiles.
    Rx PPSFactor1.0 to 100 Use this parameter to specify a received (Rx) PPS factor to use during capacity estimation (default = 1). This parameter is applicable only to custom profiles.
    Num Aor Per Subscriber1-200 

    Enter the number of Address of Records (AoRs) per subscription in an access scenario. This feature calculates the number of RCBs needed to handle all devices per subscription. The default value is 1.

    Warning

    If you use a value other than the default, the SBC SWe memory occupancy increases since the per-allocation value increases. Ribbon recommends using the SWe Capacity Estimator tool to understand the impact on SBC SWe memory when increasing the number of AORs per subscriber.

To Edit a SWe Traffic Profile

Warning

Modifying any attribute of an activated SWe Traffic Profile is service-impacting because all VMs constituting the redundancy group (1:1 or N:1) will reboot simultaneously.

On the Swe Traffic Profiles window:

  1. Click to select the radio button adjacent to the profile entry you want to edit. The Edit Selected Swe Traffic Profiles window opens.
  2. Edit the profile and click Save. 

To Delete a SWe Traffic Profile

You cannot delete the standard profiles or a custom profile that is currently in use. You can delete other custom profiles.

On the Swe Traffic Profiles window:

  1. Click to select the radio button adjacent to the profile entry you want to delete.
  2. Confirm the deletion when prompted
