XPERTrak


New QoE metric and ranking

Today’s cable modems and CMTS are capable of providing a wealth of information that can assist in

determining if a specific subscriber is experiencing poor quality of experience and just how poor that

quality is.

This information can not only provide a clear picture of whether the problem is in the upstream or

downstream, but can pinpoint the individual subscribers that are being impacted the most severely, and

provide key performance values that can indicate what the impairment is likely to be.

Using a totally new algorithm, XPERTrak now shows a list of nodes ranked by their QoE score from worst

to best, identifying those nodes that are in the most immediate need of attention.

What makes up the overall node QoE score?


XPERTrak


What makes up the new downstream QoE score?

Implementation Details:

• Server MUST be licensed to perform the QoE measurements

• MUST have valid read only community string for each CMTS and valid read/write community

strings for all full-band capture capable cable modems

• All QoE metrics have default thresholds that are adjustable by the system administrator from the

system settings page

• Correctable CWE, uncorrectable CWE, and DOCSIS SNR determine impacted subscribers in the

upstream

• Correctable CWE, uncorrectable CWE, DOCSIS SNR and Digital Video SNR determine impacted

subscribers in the downstream

Adjusting the thresholds

• To access the QoE thresholds, as well as all other QoE, PNM and downstream full band capture

settings, click on the “Configuration” icon (The gear) on the main dashboard, and select “Settings”

from the menu


XPERTrak


Enhanced Alarm Data Content in SNMP Traps The HCU name and RPM name is now contained in all alarm traps sent from the Server

• Above is the SNMP MIB Tree from PathTrak V4.5 (No HCU or RPM names)


XPERTrak


• Here is the new SNMP MIB tree from PathTrak V4.6 showing new OIDs for HCU and RPM names


XPERTrak


• Details for added OIDs

New QoE Dashboard Login Landing page Gone are the days of logging into PathTrak and seeing a tree and branch hierarchy from the server on down and a list of alarms. The new QoE landing page

• Everyone lands here. URL = http://server name (or IP)/pathtrak

• Page is filtered based on user’s Server, HCU, RPM, RPM Port, or CMTS visibility and access A. Search by RPM port name, billing system node name, or cable modem MAC address B. Daily Node Health - Chart showing % of nodes that passed and % of nodes that failed vs. QoE

threshold yesterday C. Current Node Health - Chart showing % of nodes that passed and % of nodes that failed vs. QoE

threshold in the last 15 minutes D. Churn Priority Table – A ranking list of nodes from worst to best based on QoE score E. Alarms Summary – Chart showing % of nodes that good or in any of the 4 alarm states


XPERTrak


F. Alarms – List of all current alarms. Almost identical to the old PathTrak UI G. Administrative setup icons H. Link to the Maintenance Dashboard

At a glance, determine:

• Worst performing nodes based on adjustable QoE thresholds

• How many impacted subscribers per node

• Node quality vs time

• Nodes violating adjustable performance thresholds Drill down using mobile or desktop device to:

• Determine root cause of QoE problem

• Map impaired subscribers with plant map overlay

• Trend problems over time

• Generate live displays to resolve issue, verify fix The old hierarchy view is not gone completely…yet

• Can be accessed from the “Configuration” icon and selecting “Administration”

• Several administrative functions still must be done from here.

• Creating users and user groups

• Adding and deleting HCUs

• Naming any of the system elements

• Building, importing, exporting monitoring plans

• Firmware upgrades


XPERTrak


The Maintenance Dashboard

The QoE Dashboard will show what needs immediate attention. The Maintenance Dashboard is

intended to show where there are impairments in the plant that may or may not be causing subscriber

impacting issues.

A. Pre-EQ Summary - Chart showing % upstream channels that had Pre-EQ failures as well as the % of upstream channels that do not

B. Pre-EQ List – A list showing the worst 250 channels and the node they are on listed in order from worst PNM score to best

C. Downstream Summary - Chart showing % of downstream nodes that had impairments measured by full-band capture modems and % of downstream nodes that do not have impairments measured by full-band capture modems

D. Downstream List – A ranking list of nodes from worst to best based on the downstream impairments scores


XPERTrak


Element Analysis Screen

Clicking on any of the node names in the QoE Dashboard allows you to drill down to the Element

Analysis Screen

A. Total number of modems on the node with the count of how many are impacted by CWEs or SNR

B. Upstream Metrics – Per upstream channel – MACTrak, QoE, and Pre-EQ results C. Downstream Metrics – Per node – How many modems failed vs the QoE threshold and what and

how many RF impairments are present D. RPM Spectrum Summary – Max, Avg, Min levels over the last 15 minutes E. Launch icons for PNM, CMTS Spectrum, QAMTrak, and Performance View F. Launch icons for Monitoring View, RPM Spectrum, and Performance View G. Alarm list, Broadcast list, Event log

Focused on Subscriber impact

• Metrics driven by subscriber health Problem Segmentation

• Upstream o Spectrum o MACTrak o CMTS


XPERTrak


• Downstream o Spectrum o CPE

Branches workflow to right tool

• Ingress suppression

• Localized US HFC issues

• Localized DS impairments

Plant Map Overlay

If a plant mapping tool is being used that provides an API that gives us a URL that allows the system to

access a transparent .png file of the plant, we can overlay that onto the QoE, PNM and downstream

monitoring maps


XPERTrak


Performance View

Performance view for both spectrum and MACTrak are now on the same page along with all spectrum

performance history controls

A. Spectrum History – 15 minute intervals showing pass/fail results vs the node ranking RF threshold

B. MACTrak History – Also known as MACTrak Performance Monitoring. 15 minute intervals of the rolled up NPI score. Sill the metric that produces MACTrak alarms

C. Individual channel CPI scores D. Spectrum performance history controls


XPERTrak


Spectrum summary for selected interval

• All RF performance history controls are available on the same page


XPERTrak


MACTrak Details for selected interval

• Click on any 15 minute CPI interval to see all of the MACTrak measurements during that time period

• Highlighted area matches 15 minute period selected

• Total graphs show selected 15 minute period + and – 15 minutes (45 minutes total)


XPERTrak


The return of the 3D Time Window Summary Performance History graph

• Shows signal levels at all frequencies over the specified period on time

• Graph can be rotated for best viewing angle

• Other graph styles available including line and dot (Surface shown)


XPERTrak


New Map Screens For QoE, PNM, And Downstream Monitoring

In order to improve flow efficiency within the application, XPERTrak 1.0 includes an entirely new set of map pages that allow seamless transition between QoE (Impacted subscribers), PNM, and Downstream Monitor

• PNM showing the group of impaired modems, un-equalized EQ-taps, in-channel frequency response, eTDR distance to fault, and group delay


XPERTrak


Quickly hit the QoE button and see if any of the modems have upstream QoE problems impacting subscribers at this time


XPERTrak


A quick change on the pull-down menu and now you are looking at the downstream impairments as

well as QoE (impacted subscribers)

Red dots indicate modems that have customer impacting impairments. Green dots are OK.

A. Spectrum Impairments table – Shows which RF impairments are present and how many there are

B. Metrics Table – What are the measurements for the QoE metrics. Offending metrics will turn red

C. Plant map overlay toggle.

Ongoing Conversion Away From Flash

All screens and application with the exception of the administrative functions mentioned on page 9 have been converted to JavaScript/HTML5. Those still require a Flash-capable browser, but work is ongoing to migrate all remaining items way from Flash.
