SUMMARY:Making Middleboxes Someone Else's Problem: Network Processing as a

DESCRIPTION:Modern enterprises almost ubiquitously deploy middlebox proces
 sing services to improve security and performance in their networks.\nDesp
 ite this\,  today’s middlebox infrastructure is expensive\, complex to m
 anage\, and creates new failure modes for the networks that use them. Give
 n the promise of cloud computing to decrease costs\, ease management\, and
  provide elasticity and fault tolerance\,  middlebox processing can bene
 fit from outsourcing the cloud. Arriving at a feasible implementation\, h
 owever\, is challenging due to the need to achieve functional equivalence 
 with traditional middlebox deployments without sacrificing performance or
  increasing network complexity.\n\nIn this talk\, I will present APLOMB\, 
 a\npractical service for outsourcing enterprise middlebox processing to th
 e cloud. APLOMB's motivation and design are data-driven\, guided by a surv
 ey of 57 enterprise networks\, the first large-scale academic study of mi
 ddlebox deployment. Our analysis shows that APLOMB solves real problems fa
 ced by network administrators\, can outsource over 90% of middlebox hardwa
 re in a typical large enterprise network\, and\, in a case study of a real
  enterprise\, imposes an average latency penalty of 1.1ms and median bandw
 idth inflation of 3.8%.\n
