What  will  we  do  with  OpenFlow  ?  

•  1k-­‐3k  TCAM  Entries  in  Typical  Edge  Switch  

•  Difficult  to  take  advantage  of:  – Manual  Config,  SNMP  Writes,  RADIUS  – Limited  Ac=ons  (allow/deny)  – Vendor  Specific  

•  But  what  if  you  could  program  these  through  a  standard  API  ?  

Page 14: OpenFlow)BoF) - Internet2 • OpenFlow)introduc=on) • OpenFlow)use)cases) • Currentand)future)deployments) • SoBware)and)hardware) • Demos • Discussion

Possible  Uses  of  Openflow    (Quick  Wins)  

•  Security  Applica=ons  – NAC  –  IDS/IPS  – Remote  Packet  Capture  &  Injec=on  

•  VM  Mobility  – Redirect  specific  applica=on  traffic  to  remote  site  – Flow-­‐based  forwarding  –  no  need  to  extend  en=re  broadcast  domain  –  no  STP  issues

 Other  Applica=ons    

 

•  Load  Balancing    •  n-­‐cast    

– mul=ple  streams  over  lossy  networks  

•  Load  balancing  •  Policy  (Firewall)  •  Flow  based  network  provisioning

Possible  Uses  of  Openflow  (Quick  Wins)  

•  Dynamic  Circuit  Provisioning  – Don’t  need  to  extend  layer-­‐2  end-­‐to-­‐end  – Simply  direct  specific  flows  down  a  engineered  path  with  guaranteed  priority    

– Don’t  have  to  rely  on  scripted  SSH  sessions,  SNMP  or  other  sub-­‐op=mal  ways  to  programma=cally  configure  switches/routers.

Possible  Uses  of  Openflow  (Grand  Challenges)  

•  Distributed  Control-­‐Plane  Architecture  Requires  a  Lot  of  State  to  be  Synchronized  Across  Many  Devices  

•  Many  Protocols  Needed  for  Synchroniza=on  Internally  to  Networks  (OSPF,  RSVP,  STP,  etc)  

•  Can  these  “internal”  protocols  eventually  be  removed  en=rely  with  only  BGP  for  inter-­‐domain  route  adver=sements  ?
