  1. Title or Title Event/Date Presenter, PresenterTitle, Internet2 SDX’s & the Internet2 Innovation Platform To keep our community at the “tip of the spear”, how can we support the evolution of SDX’s? Rob Vietzke -Vice President, Network Services Eric Boyd - Senior Director, Strategic Projects

  2. The Community’s Network Story (2014) • Abundant Bandwidth/100G+ • Deeply Programmable (Native OpenFlow) • Support for Data Intensive Science (Science DMZ) • Interconnected with public Internet • Supports production quality & disruptive innovation • Open for your innovation! • Provides production & innovation platform to: • Dozens of high performance compute clusters • Hundreds of campus data centers • Potentially thousands of SDN ports • Hundreds of wireless access networks • Thousands of researchers • Millions of potential collaborators

  3. Internet2 and SDXs • Internet2 operates several IXPs & Collaborates Internationally • MAN LAN with NYSERNET / WIX with MAX • Singapore Facility with Singaren • ANA-100G with ESNET, CANARIE, NORDUNET, SURFNET, GEANT • Soon: AGE-OX w/ Ankubut in Fujarah, UAE • None are currently “SDXs” • However … • Internet2 operates a backbone network … • Interconnects Starlight, AMLIGHT, Pacific Wave, MANLAN, WIX • Interconnects public exchanges too: Equinix, Telex, SIX, others • … which can also be viewed as a set of IXPs • … which can also be viewed as a single distributed IXP • The backbone network is built on an SDN substrate, arguably making it a set of SDXs

  4. Growing Use of AL2S

  5. Innovation Platform Petabytes per month

  6. Timeline • April, 2012: Announce intent to build AL2S on SDN • October, 2012: AL2S is launched • March, 2013: AL2S becomes heterogeneous • April, 2013: Innovative Applications Contest Launched • August, 2013: Begin migration of AL3S over AL2S • November, 2013: Innovative Applications Demo’d • December, 2013: AL2S supports Multpoint VLANs • March, 2013: FlowSpace Firewall debuts • June, 2014: AL2S supports network virtualization

  7. 2013 Internet2 Innovative Application Awards GOLD SILVER BRONZE • Projects include: • Video streaming • BGP routing over OpenFlow • SDN for Exchange Points • GENI integration

  8. Service Levels – Which is the SDX? • Scientist • Request: “I want to transfer data and do compute / storage between this set of endpoints with this flow pattern” • Answer: “You should use the FTP service” (or “You should videconferencing service” or “You should use broadcast service”, etc.) • Middleware Builder • Request: “I want to build an FTP Service” • Answer: “You should use the Compute service, the Storage service, and the Network Service in these configurations” • Network Operator • Request: “I want a VLAN between these two points” or “I want to control switches along this path”

  9. What is an SDX? • Basic components • SDN Switches • Controller • Virtual Machines and/or compute/storage • Challenges • Compelling applications • Programming abstractions • Scalable operations • Realistic deployment & Willing SDN peers • Analytics & Measurement • Moving bilateral pilots to multidomain operations

  10. Internet2 definition of an SDX • Includes one or more SDN-enabled Switch(es) • Standards compliant / not built on proprietary vendor extensions • Controlled by one or more SDN controllers • Must enable user-supplied controllers (virtual IXPs or virtual networks) • Platform for Innovation • Built on open source, standards-compliant software • Operationally transparent • Enables next generation of application design • Robust and scalable • Backed by an integrated test harness (software stack is complicated) • Nationwide / global footprint • Availability must exceed standard for traditional Layer 3 networks • Measurable • perfSONAR & Analytics • Operationally manageable

  11. Workshop Charge (1) • Identify trust, user authentication, resource use authorization issues • Leverage Community trust (InCommon) • Interdomain provisioning • Daisy chain models do not scale • Certificate-based approaches have regular expiration problems • Modular architecture • Enables innovation • Multiple opportunities for attack • Multiple opportunities for resource overconsumption

  12. Workshop Charge (2) • Identify interoperability issues and testing strategies for different models • Multiple (subtly different) approaches to multi-tenancy (Flowvisor, Flowspace Firewall, OVX, etc.) • Multiple approaches to integrating compute and storage resources • Monitoring software is common (perfSONAR), but what to test is still being discussed • Running a robust SDX requires multiple levels of software (Vendor implementation of OF, Multi-tenancy solution, Controller, Application, Interdomain Stitching) which requires a test harness, automated test software, etc.

  13. Workshop Charge (3) • Specify a staged set of research and prototyping activities needed to properly understand and realize these models in practice • Environment(s) to evaluate vendor implementations • Environment(s) to evaluate multi-tenancy implementations • Environment(s) to evaluate controllers • Environment(s) to evaluate cloud integration

  14. Workshop Charge (4) • Provide a strawman plan, with level of effort needed, for experimenting with a national scale SDX prototype deployment • Knit together Internet2 solution with several (3-4) implementations at traditional IXPs • Can we create a solution where someone who arrives at MAN LAN / WIX / AMLIGHT / STARLIGHT (for example) can • Deploy a controller across a multiple partner slice • Integrate with GENI Racks on 3-4 campuses • Stand up a prototype service (e.g. prototype research network without routers) • Integrate with OpenStack
