AppSharingStream Table

Lync Server 2013
 

Topic Last Modified: 2014-02-21

The AppSharingStream table contains Quality of Experience metrics for the network streams used for application sharing. This table was introduced in Microsoft Lync Server 2013.

 

Column Data Type Key/Index Details

ConferenceDateTime

dateTime

Primary, Foreign

Date and time that the session started.

SessionSeq

int

Primary, Foreign

Sequential identifier used to distinguish between sessions that started on the same date and at the same time.

MediaLineLabel

tinyint

Primary, Foreign

Represents the type of video line used in the call. Allowed values are:

  • 0 – Audio

  • 1 – Video

  • 2 – Panoramic video

  • 3 –Application/Desktop Sharing

StreamID

int

Primary

Unique identifier of the application sharing stream.

JitterInterArrival

int

Average jitter detected between RTP packet arrivals. (Jitter is a measure of the "shakiness" of a call.) High jitter values are typically caused by congestion or an overloaded media server, and result in distorted or lost audio.

JitterInterArrivalMax

int

Maximum jitter detected between RTP packet arrivals. (Jitter is a measure of the "shakiness" of a call.) High jitter values are typically caused by congestion or an overloaded media server, and result in distorted or lost audio.

RoundTrip

int

Average amount of (in milliseconds) required for a Real-Time Transport Protocol packet to travel to another endpoint and then back. Round-trip times of 200 milliseconds or less are considered of acceptable quality.

High round-trip values can be caused by international call routing; a routing misconfiguration; or an overloaded media server. High round-trip times result in difficulties with two-way, real-time audio conversations.

RoundTripMax

int

Maximum amount of (in milliseconds) required for a Real-Time Transport Protocol packet to travel to another endpoint and then back. Round-trip times of 200 milliseconds or less are considered of acceptable quality.

High round-trip values can be caused by international call routing; a routing misconfiguration; or an overloaded media server. High round-trip times result in difficulties with two-way, real-time audio conversations.

PacketLossRate

float

Average rate of Real-Time Transport Protocol (RTP) packet loss. (Packet loss occurs when RTP packets, a protocol used for transmitting audio and video across the Internet, failed to reach their destination.) High loss rates are generally caused by congestion; lack of bandwidth; wireless congestion or interference; or an overloaded media server. Packet loss typically results in distorted or lost audio.

PacketLossRateMax

float

Maximum rate of Real-Time Transport Protocol (RTP) packet loss. (Packet loss occurs when RTP packets, a protocol used for transmitting audio and video across the Internet, failed to reach their destination.) High loss rates are generally caused by congestion; lack of bandwidth; wireless congestion or interference; or an overloaded media server. Packet loss typically results in distorted or lost audio.
