                     Today’s Discussion Topic


      What we are talking about
Video delivered using Internet Protocol on a
     closed (provider managed) network


     What we are not talking about
Over the top programming or any other content
         delivered via the public Internet


                  46th Annual Winter Convention : January 20, 2009 : Kauai, HI
                                   IPTV - QoS / QoE
                               Monitoring & Assurance

• Why this Topic
• So what’s the difference from a viewer’s
  perspective ??
• I’ll bet you believed the sales person …
• You mean there’s more to it than that? ……
  Say it ain’t so
• Next we will quickly look at the difference between
  QoS and QoE, then at a block diagram and see
  what an IPTV network looks like

• Definition (it’s a matter of perspective)
   – Quality of Experience (QoE):                          (this is what really matters)
       • performance measured at application level from user perspective
   – Quality of Service (QoS):
       • performance measured at packet level from network perspective

Now, let’s look at the network diagram and see
          where things might go wrong.

• The IPTV “network” is really not “aware” of the “TV” part
• QoS is used to approximate QoE
• Empirical studies have been used to develop QoS metrics
  that “predict” equivalent QoE

                                           QoS versus QoE Metrics
– Quality of Experience (QoE): (more difficult, costly, lengthy to measure)
    •   Mean Opinion Scores (MOS)
    •   Application   (i.e. video, audio)
    •   Response      (i.e. channel change delay, VOD delay, trick mode delay)
    •   Interaction   (i.e. EPG, GUI, remote control device)
    •   Contents      (i.e. popularity, value)
    •   Reliability   (i.e. availability, consistency)
    •   Security      (i.e. contents, privacy)
– Quality of Service (QoS): (easier, less costly, quicker to measure)
    •   Bandwidth      (i.e.   Mbps, minimum guaranteed bandwidth)
    •   Circuit Type   (i.e.   CBR vs VBR; values adjustment)
    •   Latency        (i.e.   milliseconds)
    •   Jitter         (i.e.   milliseconds)
    •   Packet Loss    (i.e.   duration & frequency of error event = packet loss rate)
                       (often simplified or approximated using Bit Error Rate)
    • MDI              (Media Delivery Index)
                       (delay/jitter (Delay Factor) + packet loss (Media Loss Rate)

  – Lead Point of Contact, Point of Responsibility
       • at least 1, no more than 2: application domain & network domain (slide 7)
  – Lots of interop testing
       • EAS example
       • commitment to interoperability (but whose time, manpower, facility?)
       • no independent test labs yet, but some limited interop labs (ex: Ledcore)
  –   Stable, long-term viable partners
  –   Revision control
  –   Commitment to standards

             Technical IPTV Keys to Success
• Shorter Term
  –   Fixed, known solution set
  –   Lead Point of Contact, Point of Responsibility
  –   Lots of interop testing
  –   Extensive network documentation
       • Physical: wiring, cabling, equipment, etc.
       • Network: circuit and address maps (MAC, IP, etc.)
  – Adapt your own tools
       • devices (example: slingplayer)
       • open source community (ex: RRDTool, Cacti, Nagios)
  – Quality (QoE) should be measured periodically:
       •   at Head-End (before encoding) to check “content supplier”
       •   at Head-End (after encoding)
       •   at Subscriber (STB, codec)
       •   therefore, end-to-end view (done at turn-up and periodically)
  – Quality (QoS) should be measured consistently

                                                                                                 nn
• Shorter Term
  – PMs (QoS metrics) in every “box” in the IPTV system
  – L1/L2 monitor points:
     • BER
     • latency/jitter
     • at HE, Core Switch/Router, Edge Switch/Router, OLT, ONT, BHR, STB
  – L3/L4 monitor points:
     •   IGMP join/leave latency
     •   Packet loss
     •   Packet latency/jitter
     •   But L3/L4 functionality adds cost; not needed in every device
     •   HE, Core Switch/Router, Edge Switch/Router, OLT
  – Set thresholds for early warnings of degradation
  – Test ODN loops and end-to-end equipment (for testing only)
     •     valuable for either PON or point-to-point

• Reliability is obviously important
  – Level changes as our subscriber count
    increases
  – “If ‘x’ breaks, how much impact will this
    have on the network?”
     • Answer to this question dictates what we make
       redundant

                                Managing the Network



• Challenges
  – Size and complexity of the network
  – Nature of the service
  – Multiple vendor integration




                   46th Annual Winter Convention : January 20, 2009 : Kauai, HI
                                  Customer Perceptions



• Phone service
  – Clear demarc
  – Test point to isolate troubles
• Video
  – It’s “our” equipment running “our” software,
    all the way to the TV
  – No practical way for customer to do much
    testing

                                     Customer Perceptions



• Therefore…
  – If it’s broken, it’s “our” fault
• When we get a trouble call, we want to
  at least sound as if we have a clue

                   Where do you
                    want me to
                      put it?




A “Big Pipe” is not enough . . . or is it?

                 46th Annual Winter Convention : January 20, 2009 : Kauai, HI
                      Future IPTV QoS Issues
                              •     Content Issue
                                      –   HD+ (60 fps HD; Super HD, 3D)
                                      –   Compression limits
Where do you
 want me to                           –   Increase “symmetry”
   put it?                            –   Convergence with info sources,
                                          social networking, etc.
                              •     Transport Issue
                                      –   Bandwidth (more BW, less TE)
                                      –   Traffic Engineering (or vice versa)
                                      –   Monitoring
                                      –   Diagnostics
                              •     Home Network Issue
                                      –   Out of service provider control
                                      –   Too many boxes
                                      –   “No new wires”
                                      –   “Anytime/where”

                             Future IPTV Keys to Success
• Longer Term
  – Standardization
  – Standards integration into key IPTV ecosystem elements (every “box”)
       • ATIS IIF Standards (for interop)
       • ITU Standards (e.g. G.1081) for monitoring
       • BBF Standards for CPE (e.g. TR-069 equipped STB)
  –   Interop & certification (not just: “standards based”, “compliant”) (UNH)
  –   Revision control
  –   Product differentiation (“Standards Plus”)
  –   Point of Contact, Point of Responsibility
  –   Regulatory Policy:
       • FCC separable security
       • STB function integrated in TV (already happening in Japan)
       • ATIS ISSI downloadable security
