Parent Endpoint

Issue 7 February 2006 41

Maximum Jitter The Maximum Jitter metric represents the maximum value of jitter seen in the

RTCP reporting interval. This metric would be useful to identify transient

spikes of jitter in a session. This metric is a 32-bit unsigned integer displayed

in milliseconds. The unit is defined by the profile of the RTP session.

Media Encryption The Media Encryption metric indicates whether media encryption is enabled or

disabled for the RTP session. The Media encryption metric is an enumerated

type metric. The possible values are:

● 0 = No encryption

● 1 = AEA1.2

● 2 = AES

● 3-255 = Reserved for future use

Number Sequence

Falls

(NumberSeqFalls)

The number of sequence fall metric represents how many times during the

RTP session there was at least 1 packet that was out of order.

Number Sequence

Jumps

(NumberSeqJumps)

The number of sequence jump instances metric represents how many times

during the reporting interval there was at least 1 packet which was lost.

Octet The Octet column in the Session Table indicates the size of the packets.

Packet A packet is the logical grouping of information that includes a header

containing control information and (usually) the user data. The term packet is

most often used to refer to the application layer data units.

Packet Loss Packet Loss is the result of packets being lost in the transmission from one

endpoint to another. When packet loss occurs there could be a drop out of

words or partial words in the conversation. At low levels, poor voice quality

would result. At high levels, the conversation becomes unintelligible. Packet

Loss can result from line congestion.

Parent Endpoint The terms parent and child endpoints are purely for describing the way

endpoints are displayed in the Results List. A parent is like the branch in a tree

view. A child is like a leaf in a tree view. The same endpoint can be shown as

both a parent and a child.

A parent endpoint is any endpoint listed as a result of a search. You click on

the expanding icon positioned in the far left column to expand the parent

endpoint and show the child endpoints.
