  • Page 11: Introduction

    1 INTRODUCTION 1.1 About the Probe 1.1.1 Probe – Overview The VB220 probe enables full confidence monitoring of one Ethernet input (electrical or optical) in addition to optional contents check of one electrical ASI transport stream input. It provides detailed IP packet monitoring of up to 260 IP multicasts as well as T2MI analysis, L2TP analysis and monitoring of up to 4 Secure Reliable Transport (SRT) streams.

  • Page 12: Probe - Features

    The probe can also be managed via the VideoBRIDGE Controller – a centralized server management solution. The VBC adds management features like alarm aggregation and report functionality as well as centralized access and user roles. The VB220 probe is a module housed in a 1 RU chassis. Three probe modules may be installed in one chassis, thus tripling the monitoring capacity.
  • Page 13 The advanced Ethernet protocol analysis tool automatically detects all protocols carried over Ethernet past the port the Probe is connected to, and it displays statistics like percentage utilization of the interface and percentage of the different transported protocols. This gives the Probe a real-time sniffer capability.

  • Page 15: Principle Of Operation

    2 PRINCIPLE OF OPERATION The probe module is equipped with two RJ45 Ethernet ports and one SFP optical port. The user selects which transport stream signal input to be used by the monitoring engine, either the Ethernet video/data port or the SFP optical input. Management of the probe is conducted via the Ethernet management port or alternatively in-band via the video/data ports.

    Note: The sequence of the multicast definitions will be reflected in monitoring, so order the multicasts correctly if required. Also note that ETR 290 monitoring for Ethernet streams is disabled by default, so if this is required, it will have to be enabled by the user (on a per-stream basis).

  • Page 44: Adjusting Alarm Thresholds

    5.4 Adjusting Alarm Thresholds When the probe inputs and streams have been defined using default thresholds, the result will usually be a number of more or less permanent alarms, some which may not be relevant under the current circumstances. In order for the user to get rid of unwanted alarms, the probe provides alarm filtering functionality in the form of alarm thresholds and alarm on/off selection.

    6.7.5 Traffic — Microbitrate The Microbitrate feature allows sampling of bitrate at various sampling intervals. When enabling this feature, each Ethernet frame is timestamped in hardware on probe ingress. This timestamp is used to calculate bitrates at various sampling intervals. Due to quantisation error, the 0.1ms interval may show higher peak values than the theoretical maximum.

This traffic shape is challenging for network equipment since it demands all remaining capacity up to line speed.

  • Page 359 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. Knowing that there are usually 7 transport stream packets inside one UDP packet you expect a continuity counter error of 7 if one UDP packet goes missing.

    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 –...

    The pink line indicates a packet loss of 1-4 with no jitter component. As a rule of thumb, the co-existence of small MLR readings (1-4) and no IAT readings can be assumed to have been caused by packet loss in the original TS data. The pink line indicates a packet loss of 6 or 7 and a doubling of the jitter component.

    As a rule of thumb the IAT warning threshold could be set to 50% above the max IAT value observed over a considerable period of time, the last 24h or so. The IAT error threshold could be set a little below the maximum jitter the system can tolerate –...

    By default, the OTT profiles are identified by their URL. Some streaming systems generate profile URLs based on a session ID, and in some cases these session IDs are re-generated every time the master manifest is downloaded. In these cases, the OTT engine will see all profiles as new every round and is unable to retain any profile history.

  • Page 365 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 segment length. The graph is scaled so that 100% indicates a segment download time identical to segment length (in seconds), segment length being signaled in the profile manifest.

    D Appendix: SRT Streams D.1 Introduction D.1.1 Overview SRT is a user-level transport protocol that ensures secure, reliable transport of video and audio across multiple unstable network connections. With the UDP data transfer protocol at its base, SRT introduces several enhancements such as end-to-end encrypted data packets (using AES), improved congestion control and efficient packet loss recovery.

    D.1.3 Transmission The probe supports relaying up to two streams using RDP (Return Data Path), and these may be transmitted using the SRT protocol. SRT transmission is configured in the RDP — Setup view. When mode Relay over IP is selected, Encapsulation can be set to SRT. Encapsulation can be set to SRT when the Relay over IP mode is selected.

    E Appendix: On-line License Activation E.1 Introduction The Probe uses licenses which are activated and updated periodically over the Internet, without the need for human intervention. When the Probe sends the on-license activation over the Internet, it includes some basic information to verify the Probe.
  • Page 369 Off-line activation procedure If the VB220 network is completely disconnected from the Internet, it is still possible to activate the license using the off-line activation procedure. Click the Renew license off-line button to start the off-line activation procedure. This procedure has to be repeated yearly. Follow the steps described in the dialog to renew or activate the license.

Once done, click the Request license button and save the license document file to the computer. If needed, re-connect to the VB220 network, return to the Renew license off-line view, select the file that was generated by the license manager and press Go! .pem...

    G Appendix: Software Upload The process of performing a software upload to the probe involves the following steps: 1. Obtain the software image. 2. Export and save the probe configuration. 3. Delete any existing probe stream recordings. 4. Transfer the image to the probe using the software upload functionality in the Data — Soft- ware view or by using ftp, and save the image to flash.

  • Page 373: Delete Any Existing Probe Stream Recordings

    G.3 Delete any existing probe stream recordings If any stream recordings is stored on the probe, this may prevent software upgrade, as there might not be enough internal disk space available for the software image upload to be possible. Therefore delete any recordings prior to software upload –...

The ftp service is needed for the file transfer, and either telnet or ssh for remote login. Step 1, alternative A: Using Windows Explorer Open a Windows Explorer window.

    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 4.9.2 and reboot the probe.

  • Page 377: H Appendix: Restoring Probe Factory Defaults

    H Appendix: Restoring probe factory defaults It is possible to reset the probe to factory settings, erasing most information about the probe configuration and alarm history. For convenience, the network configuration is kept. Also note that the unit license key should be noted and stored before the factory reset is performed, as it might be reset by the factory reset process.
