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
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

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”
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
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
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
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.
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
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
