Traditional Model SDN Model
• Problem: Current networking model limits innovation, flexibility, scale & agility
• SDN separates control plane from data plane
• Benefits expected from SDN– Scale and evolve control plane independent of network devices
› Faster innovation
– Programmability of the network: better control/visibility on network traffic› Flexibility & Simplified management
– Network virtualization and service orchestration at a large scale› Scale & Agility for shared infrastructure

What is ONF (Open Networking Foundation)?
• Open Networking Foundation (ONF) is a user-driven organization dedicated to the promotion and adoption of Software-Defined Networking (SDN) through open standards development.
• ONF emphasizes an open, collaborative development process that is driven from the end-user perspective. Our signature accomplishment to date is introducing the OpenFlow™ Standard, which enables remote programming of the forwarding plane. The OpenFlow Standard is the first SDN standard and a vital element of an open software-defined network architecture.
• Organizes ONS (Open Networking Summit) – largest SDN event
12
What is OMG (Object Management Group)?
• OMG has a quarter-century history of delivering standards as part of a
whole product ecosystem -- ensuring open source implementation and/or
commercial products, education, training, books, webinars, certification, etc.
• Track record of almost 25 years and over 1,000 standards
processes proves the applicability to a wide variety of markets
• The OMG standardization process is open, transparent and
international and allows any interested party to participate.
• Dell has proposed a Software-Defined Networking (SDN)
standardization working committee within the OMG technology working
groups.13
14
What is Project OpenDaylight?
OpenDaylight is an open source project under the LinuxFoundation with the mutual goal of furthering the adoption and innovation of Software Defined Networking (SDN) through the creation of a common industry supported framework.

Historical Perspective
58
40Gb versus 100Gb Ethernet• 100Gigabit Ethernet standards do not lend themselves
within DataCenter/Campus deployment– IEEE802.3bj (backplane/twinax standard)and IEEE802.3bm (the
multimode fibre standard)are active working groups at the moment Dell is represented on these working groups
– 100m on multi-mode fiber, based on 10 x 10G, with 10 fibers per direction (100GBASE-SR10)
– 10 km on single-mode fiber, based on 4 x 25G, 800GHz spacing DWDM (100GBASE-LR4)
– 40 km single-mode fiber, based on 4 x 25G 800GHz spacing DWDM (100GBASE-ER4)
• Shorthaul 100Gb will use 10X10Gbps channels– Cost of 100gig shorthaul is currently 10-20 X 40Gb, yet is still using
channelized 10Gb; to get the real benefit it means long haul/SMF
– 100Gigabit shorthaul Ethernet will transition to 4X25Gbps, but that is not likely before 2015
61
40Gigabit Physical InterconnectIEEE802.3ba
• 40GBase-LR4– 40GBASE-LR4 uses 2 strands of single mode fiber, with four
different wavelengths of light providing the four channels, using dense wave multiplexing(DWDM). Up to 10km can be supported
