2. Goals  of  this  talk  
    
   ●  Introduce  you  to  ONOS,  its  architecture,  use  cases,  community  
    
   ●  Highlight  what  differen3ates  ONOS,  why  it  is  championed  by  
   service  providers  and  rapidly  gaining  trac3on  with  the  broader  
   community  
    
   ●  Get  you  intrigued  enough  that  you  want  to  get  your  hands  on  
   ONOS  right  aPer  this  talk!  J  
   (When  that  happens,  you  can  download  ONOS  code  at    
   hSp://bit.ly/download-­‐onos  )
