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.

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 SBC Software Environment (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 can also create a custom traffic profile 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 On the main screen of the EMA, go to All > System > Swe Traffic Profiles. The SWe Traffic Profiles window opens showing the standard profiles and any custom profiles you created.

TheSWe Traffic Profiles List window includes several standard profiles, including: 

  • default - Non-cloud instances are assigned the default profile by default. This profile retains the SBC SWe behavior of earlier releases (5.0.x and 5.1.x), where signaling and media vCPUs overlapped.
  • standard_slp_profile - This profile is auto-activated when an SBC VM is launched with an SLB personality.
  • standard_msbc_profile – This profile uses the vCPUs primarily for pass-through calls. This profile gets auto-configured on cloud-based M-SBC instances.
  • standard_callmix_profile – This profile supports call mixes that contain a combination of 90% pass-through and 10% transcoding calls.
  • standard_gpu_isbc_profile - This standard traffic profile is used when the GPU has to be used for transcoding on an I-SBC instance
  • standard_gpu_tsbc_profile - This standard traffic profile is used when the GPU has to be used for transcoding on a T-SBC instance (media transcoding unit in a D-SBC Virtual Network Function solutions)
  • 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_highcps_callmix_profile – This profile is similar to a standard pass-through profile but with a higher rate of calls per second.

To Create a SWe Traffic Profile

On the Swe Traffic Profiles window:

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

  2. Use the following table to enter the profile parameters and select Save to complete your update.

    • False (default)
    • True - SBC accepts REGISTER requests
    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

    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 - Using 100% G711 (20 ms) calls
    • G711_G729_20ms - Using 50% of G729AB (20 ms) and 50% G711 (20ms)
    Transcoding Codec ProfileN/A

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

    • G711_20ms- Using 100% G711 (20 ms) calls
    • G711_G729_20ms- Using 50% of G729AB (20 ms) and 50% G711 (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.

    Tones Percent 1-100Use this parameter to specify the percentage of legs that use Local Ring Back Tones (LRBT) and/or Announcements with in-band Dual Tone Multi-Frequency (DTMF) digit detection/collection.
    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

    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).

    The default value is 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.
