NOTE TO REVIEWERS
Please review of this page and let me know if we need to revise particular sections for SWe Lite performance vs. SBC Edge.
If you have values to add at this point please do so, but the goal of this review is to add/change structure where needed. Thanks.

FROM SBC SWe Lite - Functional Specification:
The requirements are from CHOR-2
- 10 cps
- 25 simultaneous transcoding sessions
- 25 simultaneous sessions that uses DSP
- 100 simultaneous sessions with maximum of 25 using DSP and rest using RTP Proxy or Direct media mode
- 1,000 SIP endpoint registrations
The marketing requirement is 10 CPS up to a maximum of 100 simultaneous calls. The load test average call duration is expected to be same as SBC Edge 1000/2000
In this section:
Performance Criteria
Silence suppression on test equipment is set to 62%. Average call length is set to 2 minutes. Call setup rate is 4 calls per second.
The performance numbers below depict typical scenarios. Actual performance values may vary depending upon actual configurations and applications used.

SBC 1000 and SBC 2000 Performance Numbers
Setup |
|
|
|---|---|---|
Side 1 Protocol | Max Sessions/Channels | Call Rate |
ISDN/T1 | 384 Sessions (384 ISDN/T1 channels, each associated with a single SIP channel) | 4 cps |
ISDN/E1 | 480 Sessions (480 ISDN/T1 channels, each associated with a single SIP channel) | 4 cps |
| FXS | 48 Sessions (48 FXS channels, each associated with a single SIP channel) | 4 cps |
| FXO | N/A | 4 cps |
| BRI | N/A | 4 cps |
SIP | 600 Sessions (600 SIP calls, each with two SIP channels) | 3 cps |
Call Capacity Limitation with Additional Logging
Unable to show "metadata-from": No such page "_space_variables"
call capacity is limited to four (4) calls per second when Info level logging is enabled. Additional logging verbosity reduces the call capacity.Although the call setup rate is TBD calls per second, if Call Admission Control (CAC) is enabled, calls over the rate limit will be rejected with the message 480 Temporary Not Available. Call Admission Control is implemented for SIP calls only (one leg of the call must be SIP for call admission control to be used).

*One user can have more than one endpoint connected to the SBA.
Call Forking
The
Unable to show "metadata-from": No such page "_space_variables"
supports local call forking up to eight separate destinations. Additionally, the Unable to show "metadata-from": No such page "_space_variables"
supports up to 20 early dialog responses and 20 calls forked downstream.Impact of additional Media Streams (due to Video Call Pass-through) on Call Performance/Capacity
Video calls in Hybrid/Proxy Mode
- Multiple stream for call rate: the calls per second (CPS) capacity does not change when each call contains multiple streams.
- Multiple stream for simultaneous calls: the maximum channels capacity is not affected.
- Single stream call: the calls per second (CPS) capacity is not affected.
SIP Licensing
Any SIP <-> SIP call consumes a single SIP session, for the life of the call, within the pool of SIP sessions that have been activated through a license submission..
Exceptions
No SIP session is consumed from the pool of licensed SIP sessions when a SIP<-> SIP call has on any one leg any one of the following devices:
- SBC Edge
- VX
- Tenor
You do not need to purchase a license for these SIP <-> SIP calls because the

will make accommodations.SIP Session License Consumption for SBA and CCE Deployments
SIP Session License Consumption
| Session Type (Lync Client <-> SBA <-> SBC <-> SIP Non-Lync Client) | License Consumption |
|---|---|
Lync Client to SBA
| Does not use SIP license |
| SBC to non-Lync client | Consumes SBC SIP license |
| SBC | Consumes SIP-to-SIP license |
| Session Type ( Lync Client <-> SBA <-> Lync Client) | License Consumption |
|---|---|
Lync Client to SBA
| SIP SBA license is not consumed |
Burst Behavior
If multiple calls arrive simultaneously, the
Unable to show "metadata-from": No such page "_space_variables"
will service the calls until it reaches a CPU usage threshold (~80%).- When the threshold is reached the Unable to show "metadata-from": No such page "_space_variables"will reject calls until it reaches a "safe" level (~60% CPU usage).
- When the "safe" level is reached, the Unable to show "metadata-from": No such page "_space_variables"will begin addressing calls in the queue.
Turning on the CAC or logs could exacerbate this issue.
IPsec Performance
The SBC 2000 supports a maximum of 300 simultaneous when the calls are placed over an IPsec tunnel. The SBC 1000 can handle full call capacity over an IPsec tunnel.
