Tobe Evolution Ways
Expects to NFV
NFV Benefits ( True or False )
Reduce OpEX -> space, power ( O ) ,Technicians ( ? )
Reduce CapEX -> pay as you use , Consolidations ( O )
Accelerate Time to Market -> Deploy, Reallocation ( O )
Delivery Agility & Flexibility -> Quickly Scale up or Down ( O )

DPDK Process
SR-IOV & PassThrough
Physical NIC Dedicated Divided From Physical NIC to Virtual Functions
Network Bandwidth Enhanced
(SR-IOV Supported NIC Only)
Vyatta vRouter5600 Perfor-mance
Using 2 vCPU
Direct Connect from Server to IXIA
(Using SR-IOV, 1 VM Running)
Beyond Performance, Go for Efficiency
