Diameter progress, popular use cases, roadmap - Mobicents Summit 2011

  1. 1. Mobicents  Diameter   Progress,  Use  Cases  and  Roadmap     Alexandre  Mendonça  &  Bartosz  Baranowski   8th  December  2011  @  Sochi,  RU  
  2. 2. Agenda   •  Overview   •  IntroducKon  to  Diameter   •  Architecture   •  Use  Cases   •  Roadmap   •  2010/2011  Roadmap  Review   •  Community   •  Overview   •  Releases   •  Roadmap   •  2011/2012  Roadmap  Preview   •  Releases    
  3. 3. Introduction  to  Diameter   •  Born  as  the  Next  GeneraKon  AAA  Protocol  to  replace  RADIUS   •  ..but  much  more  than  just  that,  being  widely  used  for  several   other  purposes   •  Base  protocol  defines  the  message  format,  peer  connecKon   related  operaKons  and  basics  for  AccounKng  and   AuthenKcaKon/AuthorizaKon   •  Base  (or  any  other  ApplicaKon)  is  easily  extended  by  adding   new  messages  and/or  AVPs   •  So  easy  everybody  is  having  their  own  customized  ApplicaKons,   with  barely  no  standard  ApplicaKons  usage   •  Byte-­‐oriented  messages,  consisKng  of  header  and  payload   (AXribute-­‐Value-­‐Pair,  AVPs)  
  4. 4. Architecture:  Overview  
  5. 5. Architecture:  HA/FT   Cache           Session-­‐Id:  1   Type:  X   …Data…   Session-­‐Id:  2   Type:  Y   …Data…   Session-­‐Id:  3   Type:  X   …Data…   …   Node  1   Supports  X  &  Y   Node  2   Supports  Y   …  
  6. 6. Architecture:  HA/FT   •  Selected  Session  Data  is  replicated  to  cache  a_er  processing   the  received  iniKal  Request   •  At  any  Kme,  any  node  can  pick  and  resume  any  session,  by   invoking  proper  method  in  stack  for  reconstrucKng  session   locally   •  Ideally  allow  by  configuraKon  to  prefer  to  choose  the  node(s)   which  already  have  session  locally   •  Once  session  is  reconstructed,  session  data  is  kept  locally  to   avoid  the  overhead  of  recreaKng  it  every  Kme   •  Once  session  is  terminated,  all  nodes  are  noKfied  and  clear   their  local  session  data  
  7. 7. Use  Cases:  Online  Charging  
  8. 8. Roadmap:  2010/11  Review   •  “Improve  Stability  and  Performance”   •  Jenkins  soak  test  job  running  weekly  at  750  requests/second  for   2.5  hours  in  Mobicents  JAIN  SLEE   •  Total  of  7.000.000  Requests,  usually  with  no  missed  requests.   •  Last  year  Performance  goal  was  set  to  1000  requests/second.  Got   up  to  9000  requests/second  !   •  Using  an  iMac  Core  2  Duo  @  3.06  GHz  /  4GB  RAM,  no  special  setup.   •  Eventually  with  a  beXer  setup,  the  numbers  may  go  quite  higher.     150   800   9000   0   5000   10000   Requests/s   2009   2010   2011  
  9. 9.
