Overview
The performance of the SBC VM can be optimized if the call mix is provided while configuring the SBC SWe instance. A set of predefined call mixes are provided, these are called standard traffic profiles. Additionally, a user can create custom traffic profiles, with a call mix that is more appropriate for the SBC SWe.
The supported standard profiles are:
Supported Standard Profiles
| Profile Name | Description |
|---|---|
| default | By default, non-cloud instances comes up with 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 and it is auto-configured on the Cloud based S-SBC instance. |
| standard_passthrough_profile | This profile utilizes the vCPUs for passthrough calls. |
| standard_transcoding_profile | This profile utilizes the vCPUs for transcoding calls. |
| standard_callmix_profile | This profile supports callmix which contain a combination of 90% pass-through and 10% transcoding. |
| standard_msbc_profile | The purpose of this profile is to utilize the vCPUs primarily for passthrough calls. This profile gets auto-configured on Cloud based M-SBC instance. |
| standard_highcps_callmix_profile | This profile is similar to standard passthrough profile with higher CPS and the corresponding CHT is 25. |
Once the distribution of vCPUs is set, the SBC SWe overload behavior functions the same way as the hardware SBC (5000/7000 series).
Caution
This feature is applicable only when the vcpu is more than or equal to four.
Profiles
Standard Profiles
When any standard profile is activated, the application automatically optimizes the vCPU usage of the SBC SWe VM for the activated profile.
Caution
- SBC SWe instances reboots automatically to activate the profile. All active calls are lost during this process, it is recommended to activate the profile during maintenance.
- A trap is generated when a new traffic profile is activated.
On the SBC SWe Cloud (D-SBC) appropriate profiles are auto-configured based on the personality as follows:
| Personality Type | Profile Name |
|---|---|
| I-SBC | default |
| S-SBC | standard_signaling_profile |
| M-SBC | standard_msbc_profile |
Note
On SBC SWe Cloud (D-SBC), the auto-configured profiles prevent reboot during instantiation.
Configuration Table
| Table Name | Description |
|---|---|
| sweTrafficProfiles | Contains all the standard profiles and their fixed call-mix. |
| sweActiveProfile | Contains the name of active profile and time-stamp of activation. |
| sweCodecMixProfile | Contains the standard codec_mix profiles.
|
Operational Table
| Table Name | Description |
|---|---|
| sweProcessorCapacity | This table contains the real processor capacity indices relative to a 2690v2 processor with the recommended BIOS/ESXi setting. |
| sweCapacityEstimate | This table contains the capacity estimations for all the standard profiles. |
| sweVcpuAllocation | This table contains the vcpu distribution for all the standard profiles. |
Custom Profiles
If the call mix is different from one of those corresponding to the standard profiles, a custom profile can be created. You can create custom profiles based on the call mix requirements. While creating a custom profile, you must provide the call mix through CLI.
Caution
The estimated calls per second (CPS) numbers may vary based on number of signalling messages per call and size of the messages.
