Trends  and  Directions  in  Networking  -­‐  Impact  of  Virtualization  and  Cloud  Atul  Tambe  

BNT-­‐VP  Hardware  Engineering  System  Networking  IBM,  San  Jose,  USA  

 With   the   rise  of   virtualization  and   cloud   computing,   traditional  networking  models  do  not  scale.  Software-­‐Defined  Networking  (SDN)  has  been  labeled  a  game-­‐changing  technology  in  the  data  center  and  is  gaining  market  share  in  enterprise  and  service  provider   environments.   In   this   talk,   I  will   discuss  why   there   is   so  much   interest   in  SDN,   and   present   different   approaches   to   SDN,   ranging   from   overlay   virtual  networks,   to  network   switches   that   can  be  controlled  by  an  external   controller,   to  new  forwarding  engines  that  can  better  reflect  the  requirements  of  applications.  We  will   look   at   the   impact   of   emerging   open   source   bodies   such   as   OpenStack,  OpenDaylight   and  Open  Compute  on  networking  and  how  companies   such  as   IBM  are   building   full-­‐fledged   Software   Defined   Environments   for   cloud   deployments  based  on  SDN.  The  talk  will  also  cover  the  impact  of  these  changes  on  semiconductor  solutions.
