11. SDN Impact On NFV
11

12. 12
What is SDN?
 One (of many) definitions: Control Plane (CP)
and Data Plane (DP) separation
 Logically centralized CP and distributed DP
 Software DP runs on any generic x86 hardware
 Single CP can manage multiple DPs
 Programmatic configuration
 Delivery of functions shift from Hardware model
to Software development model
DP
CP

Virtual Network Functions Evolution
• Optimized for each
function to maximize
performance
• Slow to deploy &
update
Physical
• Generic Hardware
• Fast on-demand deployment & update
• Variable performance and support for optimization
• Limited Fault Tolerance models
Virtual Container-based

14. Bringing NFV to the Linux Kernel
14

15. 15
A common development layer in the Kernel
 Need for extensibility and programmability of the Kernel to foster a new
ecosystem of VNFs that can be deployed right in the kernel
IO Visor Project provides:
 Universal in-kernel virtual machine
 Ability to create any in-kernel IO modules (user defined “programs”)
 Applications: networking, tracing, security, etc.

16. 16
Virtual Network Functions Transformation
 Any generic Virtual Network
Functions can be implemented
in the kernel
 Available in any generic
compute node running Linux
 FT is built in (redundant in each
compute node)
 Extensibility allows for new
Functions to be added over
time

17. 17
Virtual Domains for Micro-Segmentation
Private Data Center
 Isolate workloads
 Self-service provision of all network
functions
 Represent service chaining
 Decouples functions from physical
infrastructure
 Fully distributed within IO Visor
layer

18. Customer Case Study: vCPE
18

19. 19
CPE: Existing Solution
 Edge networking devices are standalone nodes
 Provide advanced services (IPAM, QoS, FW, NAT, dynamic routing…)
 Complex software, prone to failure
 Cheap hardware, prone to failure
 Can’t be easily upgraded or serviced

20. 20
vCPE: Applying “SDN”
 Move the complexity to the cloud for easy access separating functions
 But, is a simple layer-2 device what we need at customer premise?
• No local enforcement or advanced functions (DHCP,
IGMP/multicast, FW, NAT, BUM filtering, etc.)
• No support for Headless operation of data plane

23. 23
CaaS: Existing Solution
CHALLENGE:
 Hardware based networking
solution
 Long deployment cycle due to
custom network requirements
 Average 3 – 4 weeks
 Manual provisioning of network
resources
GOAL:
 Increasing customer base
 Secure custom VoIP services
 Zero downtime

CaaS: Applying SDN
SOLUTION
 Software based network
infrastructure
 Customized and secure
network deployment for
each tenant in hours
 Scale-out/ scale-in network
resources as per customer
requirements
