Skype For Business SDN Interface 2.2 Support
In ArubaOS 6.4.4.0, the controller supports Skype For Business SDN Interface 2.2. This API provides an
interface to the controller to access network diagnostic data in order to monitor Lync/Skype for Business
traffic and optimize the quality of service. This API applies to Lync Server 2010, 2013, and Skype for Business
2015.
Lync SDN API 2.1 Support
In ArubaOS 6.4.3.0, the controller supports Lync SDN API version 2.1. As part of Lync SDN API 2.1, Lync SDN
Manager (LSM) sends In-Call quality update messages to the controller. The In-Call quality update message
provides visibility on the end-to-end delay, jitter, packet loss, and MOS periodically for VoIP calls that are active.
In earlier versions of Lync SDN API, LSM sent end-to-end quality updates to the controller at the end of a VoIP
call.
Certain Lync/Skype for Business clients can generate in-call quality reports that can be processed by the Lync SDN
server and forwarded to the controller for further processing. For a list of Lync/Skype for Business clients that
support In-Call quality report, contact Microsoft® support.
Some characteristics of the In-Call quality reports are as follows:
l Lync/Skype for Business client supporting this enhancement sends an InCallQuality message every 35
seconds (by default). Lesser messages are sent for stable VoIP calls.
l InCallQuality message provides cumulative values of call quality metrics like delay, jitter, packet loss, MOS,
and more while the VoIP call is active.
l In a good call quality, the controller receives only a single InCallQuality message after the first period. No
further InCallQuality messages are sent until the end of call QualityUpdate message.
l If the call quality fluctuates and crosses the threshold, these events are collected and the sent message is
delayed until the least period of time has passed since the last InCallQuality message is sent.
