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

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

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

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
