What & Why –Open flow is looked at

OpenFlow's distinction is the separation of thethe separation of the software that provides network definition and routing from the underlying packet transport hardware.

Reduce network complexity and cost.

OpenFlow is a way, but not the only way, to address network design and operational complexity.

SINET4 Case StudyScience Information Network (SINET), which connects more than 700 universities and research institutions throughout Japan, has migrated to a next-generation backbone designed to efficiently handle demand for increasingly higher amounts of

SINET4 Case Study

SINET is primarily used for research applications requiring massive file transfers d l hi h d i h hi h h i l f i i

backbone designed to efficiently handle demand for increasingly higher amounts of bandwidth, services and users.

and ultra-high-speed in areas such as high-energy physics, nuclear fusion science, space and astronomical science, genome analysis, nanotechnology research, simulation sciences, and grid computing. It is also connected to other high-speed

h t k h I t t2 i th U S d GEANT2 i E tresearch networks, such as Internet2 in the U.S. and GEANT2 in Europe, to support international research collaboration.

SINET4 adds to the multiple network Layer 1, 2 and 3 services that were provided by SINET3 while paving the way for resource-on-demand delivery and the introduction of higher-layer services. Researchers at the National Institute of Informatics are using the Junos SDK to build and evaluate network applications on each virtual slice that leverage

Juniper is actively working in the OpenFlow Consortium

Juniper has created three SDKs toward this end (currently used by 50+ partners):used by 50+ partners):

RE-SDK—for ControlMS-SDK—for Inline ServicesSpace-SDK—for cross-node orchestration and application development

OpenFlow is a mediation layer on top of our SDK

Future Test Bed

About test bedAbout test bed

Junosphere is Juniper’s cloud based platformOffered to customers as a service to create virtual networksOffered to customers as a service to create virtual networksHosted on a data center owned and operated by JuniperJuniper is the first to offer a product in this areap p

–Proof of concept cloud running with multiple customers


Service provider case studyp y

A large Service Provider “A” expands its network via acquisition of another Service Provider “B”another Service Provider B

SP A instigates plans to merge networks, save costs, drive innovation

Years later networks are still distinct migration still being studiedYears later, networks are still distinct, migration still being studied

Largest reason? Too risky and no way to feasibly simulate a migrationUntil now


Until now….

Complexity – simplified- Future Test bed p y p

We can make this easier!With Testbed hosted in Cloud we can model, simulate, and , ,execute a seamless migration of network in months (instead of years)


Minimizes risk, accelerates deployments, advances service velocity, and drives new revenue

And the Feedback…

“This has definitely been a great opportunity for us to perform experiments in such a large network of high-end devices which otherwise would not have been possible in our labs. Working with Junosphere is really smooth and also the technical support is

ll t d tl il bl t dd ki d f blexcellent and promptly available to address every kind of problem and need.The Junosphere platform opens to us a broad range of new research opportunities allowing us to test methodologies and tools on realopportunities, allowing us to test methodologies and tools on real ISP-scale topologies. Not to mention the great added value for us to be able to teach networking concepts with tens of Juniper routers available to thenetworking concepts with tens of Juniper routers, available to the teacher and ready for being shown to the students in live sessions”
