Rob  Bristow,  NREN  Exchange  Fellow,  TENET  

4th  Nov  2014   Video-conferencing for higher education and research

Page 2: Rob bristow   tenet v-c workshop - keynote

Introductions    

»  Who  am  I?  ›  On  secondment  from  Jisc  in  the  UK  for  two  years  –  Part  of  Jisc  Futures  division  –  Worked  at  Jisc  on  video-­‐conferencing  projects  

›  What  is  Jisc?  –  UK  NREN  parent  company  –  Janet  is  the  TENET  equivalent  –  runs  national  video-­‐

conferencing  service  –  Jisc  runs  services  and  development  programmes  in  all  

areas  of  technology  and  tertiary  education  

›  What  do  I/Jisc  know  about  video-­‐conferencing  and  education?    –  Quite  a  lot!  

Page 3: Rob bristow   tenet v-c workshop - keynote

Why  are  we  here?  

»  It  is  clear  that  there  is  an  unmet  need  aroundvideo-­‐conferencing  

»  TENET  ran  PoC  with  hosted  VMRs  ›  Take  up  was  patchy  (for  a  number  of  reasons)  ›  In  the  end,  being  able  to  connect  H.323  rooms  to  each  other  was  not  

that  useful  ›  Expensive  and  not  that  flexible  

» What  else  can  we  do?  

»  Is  Adobe  Connect  the  answer?  

»  Should  there  be  a  central  “bridge”?  4th  Nov  2014   TENET   3  

Page 4: Rob bristow   tenet v-c workshop - keynote

Responses  to  questionnaires  

» Really  good  response  rate    -­‐  So  Thank  you!  » Responses  show  desire  for:  ›  Interoperability  ›  Understanding  of  the  mixed  nature  of  what  is  in  place  ›  Desire  for  some  sort  of  central  bridging  facility  » Demand  for  more  bandwidth  » H.323/SIP,  Lync  and  Skype  predominate  as  deployed  technologies  » Streaming  and  wider  delivery  seen  as  important  by  some  4th  Nov  2014   TENET   4

Teliris  Express  Telepresence  conference  

What  is  Video  enabled  collaboration?  

»  Anything  that  involves  collaboration  and  video  (but  may  also  include  other  things)  

»  From  Telepresence  to  the  desktop  

»  Room-­‐based  conferencing  

»  Desktop  conferencing    »  Web  conferencing  

»  These  things  are  now  converging  –  mobile  is  here  

»  The  goal  is  a  system  that  spans  from  web-­‐conferencing  to  Tele-­‐Presence  

»  How  to  join  things  up?  

»  Interoperability!  Desktop  Conferencing  using  Vidyo  

Page 8: Rob bristow   tenet v-c workshop - keynote

Key  benefits  (From  Jisc  study)  

»  Reduced  stress  &  time  of  travel  (75%)  

»  Better  control  of  time  (61%)  

»  Easier  to  stay  in  touch  (49%)  

»  Better  work-­‐life  balance  

»  Compensate  for  travel  difficulties  

»  Easier  to  arrange  meetings  

»  Involve  more  people  

»  Improved  communication  with  external  partners  

»  Tangible  travel  and  subsistence  savings

Page 9: Rob bristow   tenet v-c workshop - keynote

What’s  wrong  with  conferencing?  

»  The  room  is  booked  out  or  locked  

»  The  support  people  have  gone  home  

»  The  equipment  is  out  of  commission  

»  There  is  echo  on  the  audio  feed  

»  The  system  I  have  is  not  compatible  with  the  one  the    other  people  are  using  

»  The  network  is  up  and  down  and  the  video  quality    makes  this  system  unusable  

»  I  can  conference  from  a  room  but  why  can’t  I  join  from  my  laptop  or  cell  phone  or  iPad  at  my  desk,  or  at  home  or  from  anywhere  in  the  world?  

»  I  want  to  easily  share  content  from  whichever  device  I  am  using  

»  Etc…

Jisc  Project  conclusions  

»  There  are  considerable  benefits  accruing  from,  and  opportunities  for  more,  virtual  meetings  

»  Virtual  meetings  don’t  always  replace  travel  ›  new  uses  –  enabling  that  which  simply  used  not  be  possible  ›  stimulating  and  sustaining  contact  

»  Considerable  CO2  benefits  for  all  ›  largest  element  in  research  intensive  universities  is  (long  haul)  air  

»  Air  travel  generally  dominates  CO2  equivalent  travel  

»  But  overall  business  benefits  are  mainly  related  to  short-­‐medium  distance  travel  air  travel

Immersive  Telepresence  

» Very  expensive  » Senior  executives’  toy  (the  private  jet)  » Has  been  described  as  ‘telepresence  is  the  equivalent  of  a  company  having  a  single  “e-­‐mail  room”’  » In  the  end    -­‐  so  what!

Page 15: Rob bristow   tenet v-c workshop - keynote

“Legacy”  conferencing  

»  Otherwise  known  as  H.323  or  SIP  or  standards  based  

»  The  old  way  –  expensive  room  based  systems  and  heavy  duty  back  end  processing  

»  Betrays  its  telecommunications  roots  

»  Only  now  waking  up  to  the  growth  of  demand  for  mobile  and  desktop  conferencing  

»  Easy  to  use  (relatively)  »  Limited  functionality  beyond  video  and  audio  (e.g.  

content  sharing)  

»  Vendors  include  Polycom,  Lifesize,  Ayaya,  Cisco,  etc.  

»  Generally  business  –  not  education  focused

Page 16: Rob bristow   tenet v-c workshop - keynote

Web  conferencing  

»  The  other  end  of  the  spectrum  

»  Content  is  king  –  so  presentation  is  centre  stage  »  Video  and  audio  not  usually  as  well  done.  Lack  of  

echo-­‐cancellation  can  cause  really  bad  problems  

»  Good  for  push  –  webinar  or  for  where  interaction  is  not  so  important  

»  Examples  include  Adobe  Connect,  Cisco  Webex,  Blackboard  Collaborate  and  Big  Blue  Button/MConf  (open  source)  

»  Doesn’t  really  move  off  the  desktop  to  enable  bigger  groups  to  interact

Page 17: Rob bristow   tenet v-c workshop - keynote

Consumer  and  desktop  clients  

»  Skype  ›  Great  for  one  to  ones  and  presence  

›  Network  parasite  

›  Can’t  interoperate  with  anything  else  

»  FaceTime  

›  Apple  only  

»  Lync  ›  Part  of  the  MS  Office  stack  –  so  on  a  lot  of  desktops  

›  Replacing  traditional  telephony  –  soft  phones  

›  Can  interoperate  with  many  other  systems  

›  One  to  watch

Transcoderless  and  scalable  Video-­‐conferencing    

»  These  use  variants  of  the  SVC  extension  to  theH.264  video  compression  standard  (Annex  G)  

»  Sends  a  base  layer  which  is  enough  –  and  then  enhancement  layers  as  the  circumstances  dictate  

»  Traffic  goes  through  a  media  router  –  but  the  decoding/encoding  is  done  intelligently  on  the  end  points  

»  Endpoints  get  the  resolution  and  detail  they  can  handle  

»  Advantages:  

›  Efficient  low  cost  infrastructure  –  backend  is  much  cheaper  than  traditional  MCUs  

›  Excellent  network  resilience    -­‐  copes  well  with  variable  bandwidth  situations  

›  Real  time  adaption  –  constant  tailoring  of  what  gets  sent  to  each  end  point  

›  Flexibility  

»  Gateways  to  H.323/SIP  world

Uses  of  video-­‐conferencing  -­‐  Music  

»  LOLA  –  Low  Latency  Project  

»  Enable  real  time  musical  performances  where  musicians  are  physically  located  in  remote  sites  –  useful  for:  

›  Rehearsals  before  a  concert    

›  Masterclasses  

›  Performance  with  distributed  performers  

»  Heavy  network  requirements:  

›  Needs  from  94Mbps  to  500Mbps  end-­‐to-­‐end  

›  Network  jitter  must  be  very  stable  (<3ms  at  30fps,  <6ms  at  60fps)    

›  Hops  must  be  minimised,  and  firewalls  opened

Cloud  services  &  Integrators  

» But  we  may  still  have  islands  on  video-­‐conferencing  

» Enter  the  integrators  and  cloud  services  » But  most  of  these  mean  traffic  going  to  Europe  or  the  US  –  so  not  really  an  option  at  present  in  South  Africa  

» Promise  of  any  system  connecting  to  any  system  –  but  this  really  means  going  via  H.323/SIP  for  now  

4th  Nov  2014   TENET   21  

Page 22: Rob bristow   tenet v-c workshop - keynote

Some  emerging  themes  

»  Software  endpoints  and  infrastructure  ›  Much  cheaper  ›  More  flexible  ›  User  provisioned  and  launched  

»  Cloud  based  offerings  –  pay  for  what  you  use  

»  Desktop  and  mobile  –  anyone  connecting  from  anywhere  

»  Unified  communications  –  presence,  IM,  telephony  and  video  

»  The  right  tool  for  the  job  »  Video  in  browser  –  WebRCT  

4th  Nov  2014   TENET   22  

Page 23: Rob bristow   tenet v-c workshop - keynote

UK  Developments  

»  Janet  (UK  NREN)  recently  launched  new  service  called  V-­‐Scene  

»  Old  offering  was  a  farm  of  MCUs  and  a  rather  clunky  booking  service,  along  with  a  dreadful  desktop  client  

»  Some  advice  and  guidance  on  purchasing  and  use  

»  Quality  assurance  of  endpoints  

»  But  use  was  patchy  and  seemed  mostly  directed  at  schools  

»  Some  heavy  use  in  colleges  with  multiple  sites  

»  New  Platform  incorporating  Vidyo  for  desktop/personal  and  Cisco  MCUs  for  H.323/SIP  

09/10/14   TENET   23  

Page 24: Rob bristow   tenet v-c workshop - keynote

VIDYO  

»  Scalable,  modular,  flexible,  configurable  

»  Mostly  virtualised  

»  Good  traction  in  research  communities  (CERN,  SKA)  

»  Desktop  and  web  client  

›  All  participants  can  share  content  

»  All  registered  user  get  a  virtual  meeting  room  

»  Room  systems  

»  Gateway  to  H.323/SIP  

»  Pay  as  you  use  pricing  model  

»  API  and  SDK  allows  for  custom  intgration  options  

09/10/14   TENET   24  

Page 25: Rob bristow   tenet v-c workshop - keynote

Vidyo  at  CERN  

»  CERN  needed  to  scale  V-­‐C  capabilities  

»  Traditional  V-­‐C  was  way  too  expensive  

»  Settled  on  Vidyo  »  20,000  user  accounts  »  Routers  in  many  locations  (one  coming  on  line  

in  Cape  Town)  

»  Over  800  concurrent  connections  at  peak  

»  Cool  graphic  here:  http://avc-­‐dashboard.web.cern.ch/Vidyo  

»  CERN  asked  TENET  to  provide  hosting  for  Vidyo  Router  for  SA  use

So  what  to  use?  

»  What  do  you  want  to  do  ›  Teaching  and  learning  ›  Research  collaboration  and  coordination  ›  Outreach  

›  Administration  

»  What  does  you  have  in  your  university?  ›  Rooms  ›  Desktop  

»  What  can  you  get  access  to  via  the  cloud?  ›  Some  of  the  new  approaches  can  be  run  in  a  browser  –  Web  RCT  

09/10/14   TENET   27  

Page 28: Rob bristow   tenet v-c workshop - keynote

Who  will  use  it?  

» Admin  ›  Split  sites  ›  Cross  institutional  organisations  » Research  collaboration  ›  Project  management    » Teaching  and  learning  ›  Video-­‐conferencing  everywhere  ›  Record  sessions  or  stream  to  wider  internet  ›  Role  here  for  Web-­‐conferencing?  

09/10/14   TENET   28  

Page 29: Rob bristow   tenet v-c workshop - keynote

And  finally  –  some  words  of  advice  

»  Local  Network  Configuration  needs  to  be  stable,  and  in  particular  firewalls  need  to  be  correctly  configured.    

»  Room  systems  need  to  be  properly  configured  including  network  and  routing  settings.    

»  Meeting  rooms  need  to  have  good  acoustics  and  good  light    

»  Provide  good  quality  audio  play  back  in  rooms    

»  Laptop  /  PC  /  mobile  users  need  to  have  reasonable  spec  hardware  &  preferably  headset  and  microphone  (although  Vidyo  has  built  in  echo  cancellation)  

»  Laptop  /  PC  /  mobile  users  can  connect  using  only  a  web  browser,  but  get  more  functionality  if  they  install  the  Vidyo  client  before  connecting.    

»  Test  the  setup  before  a  meeting  starts,  not  when  the  meeting  is  supposed  to  start  

»  However  good  the  hardware  is,  bandwidth  across  the  internet  will  always  be  a  limiting  factor,  however  latency  is  even  more  critical.    

»  User  familarisation  and  expectations  are  key  –  make  sure  people  understand  how  to  use  the  system  and  kit
