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.

Use Case for SDN/NFV

15

• 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 input and output ports (Virtual & Physical) connecting VNFs


Load Balancer Use Case

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


Extensibility WG Status

20

• OpenFlow 1.0.2– Done – November 2013 - TCP port is 6653

• OpenFlow 1.3.4– In ONF wide review - Please review !– 1.3.4-rc3 released – see mailing list– 37 erratas – Plug-fest & vendor feedback– Release April 2014

• OpenFlow 1.5 & ONF Extensions– In Incubation phase – no new proposals– Incubating & prototyping proposals– Release mid to end 2014

• OpenFlow 1.6 & ONF Extensions– After 1.5 is done– Themes defines area of focus

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 fields21


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):

L3 Header

Window of match field value, with mask option

• 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
