Midstream Details Tables

The Midstream Details tables provide in-depth data about the performance of RTP traffic flows (or stream legs) on the medianet-enabled devices on your network.

Device

The name of the medianet-enabled (midstream) device that is associated with the stream leg. Can be the DNS name or the IP address.

DSCP

The Differentiated Services Code Point setting of the incoming RTP packets.

Egress Interface

The interface where traffic exits a device.

Forwarding Status

When applicable, this field explains why a medianet-enabled device did not forward packets as expected. For example, when the device drops packets, this field provides a Status of “Dropped” and a Reason such as “Bad TTL.”

The device manufacturer provides the Status and Reason descriptions. Two other descriptions provided in this field, Value and Extended, are not defined, and can vary depending on the Status and Reason.

When a forwarding status is available, this field contains a blue “i” icon. Position your mouse pointer over the “i” to review the information.

Ingress Interface

The interface where traffic enters a device.

Jitter, Max Jitter

Packet delay that distorts the quality of a voice conversation. Either the average or the maximum value for the stream leg.

Packet Loss

The percentage of data packets that were lost in transit. These packets were sent but never received at the destination.

Packet Rate

The number of data packets that are received per second. UC Monitor uses this value to determine whether an RTP stream is audio or video for medianet-enabled devices that do not report a codec.

Packets Dropped

The number of data packets that reached the destination, but then were discarded.

Packets Lost

The number of data packets that were lost in transit. These packets were sent but never received at the destination.

Packets Received

The number of data packets in a stream.

TTL

(Time to Live) A counter embedded in data to prevent a data packet from circulating through the network indefinitely. The counter decrements each time that the packet passes through a router or a switch.

Video Jitter, Video Max Jitter

The variation in delay among video packets in the same stream. Either the average or the maximum value.

Video Packet Loss

The percentage of video packets that were lost in transit. These packets were sent but never received at the destination.

Video Packet Rate

The number of video packets that were received per second.

Video Packets Dropped

The number of video packets that reached the destination, but then were discarded.

Video Packets Lost

The number of video packets that were lost in transit. These packets were sent but never received at the destination.

Video Packets Received

The number of video packets in a stream.
