Video  Predominant  on  the  Internet  

•  Real-­‐3me  video:  >  50%  of  the  traffic  •  Mainly  delivered  over  the  top  using  HTTP  

•  ...  but  the  user  frustra&on  is  s&ll  high!  ➪  Let’s  do  something

Dynamic  Adap3ve  Streaming  over  HTTP  

•  ISO/IEC  MPEG  Standard    [ISO/IEC  23009]  –  Media  presenta3on  descrip3on  (MPD)  and  segment  

formats  (ISOBMFF,  M2TS)  •  Dynamic  adap3on  to  the  usage  environment  •  Usage  of  exis3ng  Internet  infrastructure  •  Adapta3on  logic  &  intelligence  at  the  client  ➪  Flexibility  and  scalability

DASH/2.0  

•  MPEG-­‐DASH  adopts  HTTP-­‐URLs  to  iden3fy  segments  within  the  MPD  but…  …  does  not  mandate  its  usage  …  does  not  mandate  a  version  

•  HTTP/2.0  currently  under  development  within  IETF  (based  on  SPDY)  –  Based  on  TCP,  single  persistent  connec3on  –  Allows  mul3ple  streams  between  client  &  server  –  Exchange  of  frames,  compa3ble  with  HTTP/1.1

DASH/2.0  Client  Support    •  MPEG-­‐DASH  VLC  plugin  

– World  first  MPEG-­‐DASH  implementa3on  –  Open  source,  part  of  well-­‐know  VLC  ➪  hZp://dash.itec.aau.at  

•  libdash  –  tree/hZp2  – MPEG-­‐DASH  reference  sokware  –  Open  source  &  sample  player  ➪  hZp://bitmovin.com/libdash  

•  Basis  for  products,  e.g.,  bitdash  –  Adapta3on  logic  with  +100%  throughput

Content-­‐Centric  Networking  •  From  a  host-­‐centric  to  the  content-­‐centric  

approach  –  Addressing  loca3on  vs.  content  –  Different  terminology:  ICN,  NDN,  CCN  

•  CCN  approach  –  Interest  packet:  request  for  content  –  Data  packet:  delivery  of  content  –  Network  ac3vely  par3cipates  in  the  delivery  

•  CCN  features  –  Na3ve  support  for  content  caching  –  Loca3on  independence  –  Mul3-­‐path,  mul3-­‐source  delivery  –  Security  and  trust  as  an  integral  part  of  the  network  

CCN  6

DASH  and  CCN  :=  DASC  

•  Common  elements  –  Client-­‐ini3ated  pull  approach  –  Content  being  dealt  with  in  pieces  (segments,  chunks)  

•  Two  op3ons  for  integra3on  –  Proxy  service  ac3ng  as  a  broker  between  HTTP  and  CCN  

–  DASH  client  implemen3ng  a  na3ve  CCN  interface    

•  Na3ve  approach  enabled  by  DASH  –  CCN  naming  scheme  (CCN  URIs)

Conclusions  •  DASH/2.0  

–  HTTP/2.0  (SPDY)  ~  HTTP/1.1  with  persistent  connec3ons  &  request  pipelining  

–  Implicitly  solves  Head-­‐of-­‐Line  blocking  problem  –  HTTP/2.0:  IETF  hZpbis  WG,  proposed  standard  by  end  of  2014  

•  DASC  –  It  works,  performance  comparable  but…  –  Improvements:  request  pipelining,  caching,  encryp3on/signing  

–  ICNRG  within  IRTF  •  Join  this  ac3vity,  everyone  is  invited  –  get  involved  in  and  exited  about  DASH!
