  • Page 9: Introduction

    The VB330 10G Probe can also be managed via the VideoBRIDGE Controller. The VideoBRIDGE Controller will add management features like alarm aggregation and report functionality. The VB330 10G Probe is a module housed in a 1 RU chassis. Several VB330 modules may be installed in one chassis, extending the monitoring capacity.

  • Page 10: Probe - Functionality

    1.1.2 10G Probe – Functionality An IP-based network is fully transparent with respect to signal contents quality, provided that the IP packets arrive, and provided that they arrive in time. The 10G Probe therefore uses the patented MediaWindow to allow monitoring at-a-glance of packet loss and errors in inter-packet arrival time. This way the operator can conveniently ensure correct signal quality at IP-level.

  • Page 11: How To Use This Manual

    Chapter 6 THE 10G PROBE GRAPHICAL USER INTERFACE describes the graphical user interface (GUI) as seen when pointing a web browser to the 10G Probe’s IP address. A Appendix: VB330 Versus VBC Alarms describes the alarm handling in the 10G Probe versus the VideoBRIDGE Controller.

  • Page 14: Safety

    3 SAFETY Read the installation instructions before connecting the chassis unit to the power source. Do not install the chassis unit with power on. The chassis is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Blank face plates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis, they provide electromagnetic interference shielding and they direct the flow of cooling air through the chassis.

    4.2.1 Dual Power Supply The Enhanced Chassis (VB300) is delivered with two 100–240V AC / 75W power supplies, providing power redundancy. In normal operation load is shared between the two power supplies. If mains fall-out occurs for one of the power sources or one of the power supplies fails, the power supply still in operation will take the full load, seamlessly.

  • Page 17: Cooling System

    4.3.2 Cooling System The chassis is equipped with six long-life fans that suck in air from front of the chassis. The air exits at the back of the unit. The fans are temperature controlled, allowing them to run at an optimum speed. Venting holes at the sides of the chassis provide an optional air intake, ensuring good aerodynamical properties of the cooling air flow.

    SFP+ B: SFP+ optical interface – main data input. The VB330 module’s SFP+ B port is shipped with an SR (short range) SFP+ module. This should be replaced if the system requires a different SFP+ module, e.g. for use with single mode fibre. Note that using other SFP+ modules than the type shipped may imply that special safety precautions must be taken, like using protective glasses.

  • Page 188: A Appendix: Vb330 Versus Vbc Alarms

    A Appendix: VB330 Versus VBC Alarms The VB330 10G Probe alarms are independent of the VideoBRIDGE Controller alarms. The 10G 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 10G Probes.

  • Page 189: 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 190 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 191: 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 192: 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 193: 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 194: 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.

    C.2 OTT Profile Health Timeline The OTT profile health timeline shows information about channel bitrate and channel alarm status for the last two hours, with a time resolution of one minute. Green parts of the timeline indicate profile download time versus chunk length. The graph is scaled so that 100% indicates a chunk download time identical to chunk length (in seconds), chunk length being signalled in the profile manifest.

    Probes that are unable to execute the user program (usually caused by interrupting the save-to-flash process described above) can still be upgraded. Contact Sencore for details. To verify that the probe is unable to start the user program, connect the USB cable as explained in section 4.8.2 and reboot the probe.
