Web  Service  Accuracy  in  DoD  Networks  

The  Importance  of  WS-­‐Reliability  and  WS-­‐Addressing  in  DoD  Networks  

Presenter  

•  Presenter:  Jared  Ladner  •  Company:  Geocent

Web  Services  in  DoD  Environments  

•  Service  OrientaGon  plays  a  big  role  DoD  “SOA  is  so  strategic,  in  fact,  that  SOA  underlies  how  the  DoD  expects  

to  achieve  its  mission  in  the  21st  century”  ZapThink    

•  DoD  is  an  organizaGon  of  outstanding  complexity  

•  Mission  CriGcal  Services  

Web  Services  in  DoD  Environments  

Net  Centric  Warfare  

•  Robust  network  for:  improved  informaGon  sharing,  and  shared  situaGonal  awareness    

•  InformaGon  as  Strategic  Military  Asset  – The  right  informaGon,  at  the  place,  at  the  right  Gme  

•  Goal  is  to  achieve  Agile  InformaGon  •  Represents  a  fundamental  shiT  in  military  culture,  away  from  powerful  compartmentalized  war  machines  and  toward  interconnected  units  operaGng  cohesively  

Global  Informa<on  Grid  

•  InformaGon  as  Strategic  Military  Asset  –  InformaGon  is  needed  at  the  right  Gme  

WSDL  and  SOAP  

WSDL  and  SOAP  were  never  designed    to  model  complex  interacGons.  The  limitaGons  include  no  standard  ways  to:  

•  Define  a  "unit  of  work"  spanning  mulGple  operaGon  invocaGons  (begin  /  end)  

•  Specify  the  sequence  in  which  operaGon  needs  to  be  invoked  

•  Correlate  operaGons  invocaGons  as  part  of  a  unit  of  work  

•  Specify  the  intent  of  a  SOAP  message

•  Support  message  transmission  through  processing  nodes  such  as:  – endpoint  managers  – Firewalls  – gateways
