Hundreds of SDN Jobs
Interop: What's Driving SDN Today?
There are multiple ways in which SDN is being deployed today, with OpenFlow controller-
based approaches leading, cited by 33 percent of respondents. 31 percent of respondents
said that they were using overlay-based SDN approaches, which include VMware's NSX and
Juniper's Contrail. 27 percent of the study's respondents said that they were using an SDN
controller with multiple protocols and APIs

ONF on OpFlex
Posted on April 3, 2014 by Dan Pitt
ONF Executive Director Dan Pitt offers his thoughts on OpFlex, openness, and the
southbound interface.
Many people have approached ONF for feedback on Cisco’s announcement of OpFlex. While some are making this
a battle between standards, others are simply asking what the role could be for both OpFlex and OpenFlow in
SDN. While we’ll have some additional commentary on OpFlex in the days to come, I’d like to share a few
thoughts with you now on the importance of being truly “open” and what we see as the essence of SDN.
“Open Network Linux” could boost viability of vendor-neutral switches
by Jon Brodkin - Apr 4 2014, 10:50am +0900
LAS VEGAS—The Facebook-led Open Compute Project has spent the past year building an “open” switch that can
boot nearly any type of networking software, giving customers more alternatives to proprietary switch vendors like
Cisco.
Intel, Broadcom, Mellanox, and Cumulus Networks jumped on board last November, contributing specifications
and software that will bring the project closer to a finished design. They weren’t alone, though: Software-defined
networking vendor Big Switch Networks, in January, donated what it calls Open Network Linux (ONL) to the
project.

• OpenFlow as the Service
Chaining Protocol
• Enterprise Network
Functions such as Firewall,
WAN Optimization, Load
Balancer and QoS
• Traffic Classification using
OpenFlow
• Service Chain is a list of

Specification Parallel Tracks
Constraints
• Incremental improvement on 1.X pipeline
• Board decided 1.3.X is a long term release
Goals
• All kind of networking devices – flexibility
• Software devices want rapid innovation
• Hardware devices want stable and solid releases
• Grounded and real – require prototyping
Plan
• OpenFlow 1.3.X specification : long term support
• ONF Extensions for 1.3.X : new features
• OpenFlow 1.X specifications : extensibility, incremental pipeline
improvements
• OpenFlow 1.0.X : no work planned
19

Discussions: 5 themes for 1.5
• 5 themes
• Tunnel handling improvements
• Flow local control (learn, bidir, state...)
• L4/L7 service support (steering, chaining...)
• Error / anomaly handling
• Fitness for carrier usage
• Some of the other proposals for 1.5
• EXT-109 - Match on TCP flags
• EXT-334 - Make flow statistics extensible
• EXT-340 - Time Extension
• EXT-350 - Selectively add & delete group buckets
• EXT-379 - Make meter an action
• EXT-388 - Port pipeline field metadata
• EXT-427 - Controller able to send pipeline fields
21
Open Flow Extension for Traffic Steering
• Simple Extension (Phase 1)
– OF Extension to control L4-L7 traffic steering
(stateless, same as today’s OF wire protocol)
– Redirect traffic to 3rd party generic appliances, i.e.
create a tunnel to pass traffic across some network
nodes/links
• Stateless Extension with floating pointer
(Phase 1.5):
– With floating pointer for matching criteria.
E.g. with a bitmap for matching criteria
– Index to existing fields plus offset & length
• Tracking flows: learning micro(Individual)
flows and keep the states (Phase 2)
– Learn new 5 tuples, and apply actions
• More sophisticated OF Extension (Phase 3):
– Combine more than one packets to match HTTP
header
• Longer term OF Extension (Phase 4):
L2 Header
L3 Header
L4 Header
Payload
Pointer
Match
Window of
match field
value, with
mask option

25
• The abstract switch forwarding model
Myths & Misconceptions
• SDN is Network Virtualization
• SDN == NFV
• SDN is about centralized control
• OpenFlow is not mature
• OpenFlow does not scale
• Do we really need another protocol?
• We can’t just throw away our existing networks

Summary: Overcoming Global Tech Trend
 SDN기반의 NFV 관련 표준화를 고려하는 개발 계획
 관련 분야를 포함하는 저변 확대
 글로벌 시장 진출 기회
