NAM RTP Stream Traffic
As can be seen from Figure 6-15, the NAM has the ability to collect detailed performance data from RTP
flows down to individual synchronization sources (SSRCs), including packet loss counts for the session,
packet loss percentages for the session, jitter, and whether the RTP session is still active. Further
information can be viewed by highlighting and selecting the details regarding each individual flow, as
shown in Figure 6-16.
Figure 6-16
RTP Flow Details
Here you can view the flow in increments over time, to see whether the packet loss and high jitter levels
were a one-time event during the session, or were continuous throughout the session. This level of detail
can be used to assist in identifying performance issues within the network down to the level of individual
cameras within a multi-screen (CTS-3000) TelePresence meeting.
