The overall status for the Full Service Monitoring (FSM) is also shown. Throughout this view the bulb colors indicate the most severe active alarm.
Page 93: Multicasts - History
6.4.4 Multicasts — History The probe keeps statistical Ethernet information for the last 4 days for visual inspection in the history timeline view. Each bar in the histogram corresponds to a number of events that occurred within a certain time interval. The interval that each bar represents depends on the scale, from 1 minute (when 90 min is selected) to 1 hour (when 4 days is selected).
Page 94: Multicasts - Join
Tot bitr: Bitrate sensed on the eth0 interface Mon bitr: Bitrate on eth0 corresponding to joined multicasts CRC errs: Detected CRC errors. Ethernet CRC errors are most likely caused by a bad cable or a misconﬁgured router. A CRC error may impact packet loss measurements such as CC errors and RTP errors.
Page 95: Multicasts - Streams
6.4.6 Multicasts — Streams In this view the operator can deﬁne multicasts available to the probe and associate a name with each multicast address. This name will be used by the probe when referring to the multicast. If no name has been deﬁned the probe will use the multicast address:port notation.
Page 96 General Name: A name should be assigned to each unicast/multicast. The name will be used throughout the VB220 user interface when referring to this stream. It may also be used by an external management system like the VideoBRIDGE Controller. Address: The IP address of the unicast or multicast.
Page 97 SSM source 1: If source speciﬁc multicasts (SSM) is enabled in the VB220 and a zero source address is speciﬁed for a multicast it will be joined using IGMP version 2 (i.e. without a source). This allows both source speciﬁc multicasts and non-source speciﬁc multicasts to co-exist in the same network and be joined by the VB220.
Page 98 Select ETR engine: If the probe is licensed for several Ethernet ETR engines the user may select which engine should be used to analyze the stream. The default ETR engine selection is Ethernet1. It is also possible to use the Distribute ETR engines button described above to assign streams to engines.
Page 99 Redundancy Has FEC: The stream carries COP3 (SMPTE 2022-5) Forward Error Correction. If enabled, statistics about FEC drops and correctible errors will be reported for the stream. First stream: For a Seamless Protection Switching (SMPTE 2022-7) protected stream, select the ﬁrst of the two redundant RTP streams here. For other streams, (none) should be selected.
Page 100: Multicasts - Ethernet Thresh
6.4.7 Multicasts — Ethernet thresh. Thresholds are used to determine when to actually raise an alarm upon detection of an error. The Ethernet thresholds are used for generating Ethernet probe alarms as well as for calculating error-seconds. Error seconds and ETH probe alarms are issued whenever measurements exceed the deﬁned threshold levels for a parameter.
Page 101 Ethernet thresholds Name: A text string that identiﬁes the Ethernet threshold IAT:MLR error: This threshold contains error limits for IAT (Inter-packet Arrival Time) and MLR (Media Loss Rate). The IAT limit is the ﬁrst parameter (before the colon), the MLR limit is the last parameter.

Page 238: Setup - Vbc Thresh
6.17.10 Setup — VBC thresh. The VBC error second thresholds are used by the VideoBRIDGE Controller to issue VBC speciﬁc alarms. The VBC will raise an alarm when the number of error seconds exceeds the error seconds threshold. The VBC thresholds are only relevant when a VideoBRIDGE Controller is part of the monitoring system. The reason for using error second thresholds is to avoid alarms that toggle on and off, which for a large monitoring system might otherwise lead to an unintelligible user interface.

Page 252: A Appendix: Vb220 Versus Vbc Alarms
A Appendix: VB220 Versus VBC Alarms The VB220 Probe alarms are independent of the VideoBRIDGE Controller alarms. The Probe has been designed to yield instantaneous alarms based on the current measurements. This typically results in lots of short-lived alarms that would be “too much” for the VBC to report, as the VBC may control a large number of Probes.
Page 253: B Appendix: Monitoring Practices
B Appendix: Monitoring Practices This Appendix summarizes a few useful monitoring practices. B.1 RTP Monitoring When running video inside an RTP wrapper it is possible to exactly deduce the number of dropped IP frames due to network issues. This is possible as a result of the 16-bit sequence counter inside the RTP header.
Page 254 Imagine the following MPEG-2 Transport Stream being generated by an encoder. The TS contains two PIDs (50 and 51) and the Continuity Counter (CC) values are continuous for each PID since there are no packets missing. PID: 50 PID: 51 PID: 50 PID: 51 PID: 50...
Page 255: Strategy For Mediawindow Analysis
B.3 Strategy for MediaWindow Analysis This section provides further insight into MediaWindow analysis and suggests how the Ethernet threshold settings can be conﬁgured to maximize the usefulness of the MediaWindow graphs and alarms. The MLR value is always calculated using the continuity counter inside the transport stream packets. Since the continuity counter is expected to increase by one for each packet of the same PID it is possible to detect missing TS packets by noting gaps in the continuity counters.
Page 256: Iat Before And After Router
B.3.1 IAT Before and After Router Packet-loss that occurs before or inside a router will usually not be visible since the queuing mechanism at the outgoing interface of the router will send out packets in an orderly fashion. If however the packet-loss did occur after the router (due to line noise for example) thus affect the timing between two neighboring packets –...
Page 257: Identifying Udp Packet Loss
For VBR streams a similar packet-loss will not necessarily affect the IAT graph even if the time between two neighboring packets doubles. The pink line represents the IAT and MLR value measured for the missing packet. B.3.2 Identifying UDP Packet Loss This discussion does not apply to streams with TS/RTP mapping since in that case identifying UDP packet loss is straight forward.
Page 258: Multicast Thresholds
As we have seen, there is no sure way to distinguish between UDP packet-loss and loss in the underlying TS packets. One way to deal with the situation is to have a probe doing zero readings close to the signal source before the network can introduce UDP packet loss.
Page 259: Ott Bandwidth Requirements
B.7 OTT Bandwidth requirements The recommended available bandwidth for full coverage OTT monitoring is equal to the sum of the proﬁle bitrates monitored plus an estimated overhead of 20 % for manifests and IP, TCP and HTTP headers. Note: The OTT engines will be using all available bandwidth on the interface in spikes while downloading the chunks, this is the main reason why it is not a good idea to mix multicasts on the same interface, as it can cause packet drops which multicasts cannot handle.
