1 Internet2 and AL2S Eric Boyd Senior Director of Strategic Projects
But how are we going to do this bit? Eric Boyd Senior Director of Strategic Projects

2 = University Corporation for Advanced Internet Development
Internet2 Mission University Corporation for Advanced Internet Development = “Advanced” is why Internet2 exists.

3 This is what we have been able to say for about a year: The 100G testbed of innovation for tomorrow’s Internet is available nationwide, right now.

11 Network Virtualization on Internet2
Control a slice of the national network! Enable: Rapid prototyping of advanced applications Rapid prototyping of new network services Rapid advancement of network research “Advanced” is why Internet2 exists.

12 Network Virtualization on Internet2
Network Virtualization: Puts members in control of (a slice of) the network Change in paradigm: Turning the “commons” on its head Private network capabilities with shared network costs Large scale networking is normally about lowest common denominator Large scale virtualized networking is about creating custom facilities Extend the local domain into the national (eventually global) arena

13 Network Virtualization Use Case
For most applications run in a campus environment, the traditional routed Layer 3 infrastructure provided by the Internet2 Advanced Layer 3 Service (AL3S) provides all the needed functionality and performance. For some applications, the ability to run on a server in a campus environment or on a GENI Rack, connected by a Layer 2 VLAN, should suffice. For a few advanced applications, particularly in the network research arena, there is a need to run their own controller on a virtual network. General use case for supporting network virtualization on the Internet2 Network.

14 Use Case Examples (1) Production Service Staging Network Research
GENI wants to move to Stitching v3.0, but Stitching 2.0 is in wide use Set up a slice, deploy a second OESS, deploy new version of FOAM Stitching Aggregator When it’s tested and ready, move to the production OESS stack Network Research Network researcher has a better idea how to do networking Set up a slice, deploy new network controller, write paper Service Prototyping Look at alternatives to AL3S Implement a route server that speaks OpenFlow on southbound interface with no routers Deploy in a slice, begin peering with other domains Evaluate efficacy, operational savings Over time transition to new service

15 Use Case Examples (2) Private Networks
Want something akin to Atlantic Wave, original vision for LHCONE, or GENI Virtual Network Set up a distributed SDX across multiple domains Network virtualization experiments are already underway Prototyping IP over SDN solution (no routers!) Prototyping cloud-based services Prototyping multi-domain virtual networks DANCES

16 Technology behind Network Virtualization
Vendors such as Brocade provide switches that implement OpenFlow. Through close development partnerships, Internet2 can deploy advanced technology. Internet2 and Indiana University have developed a second-generation, open source hypervisor, called Flowspace Firewall (FSFW). FSFW divvies up the available VLANs on a network into VLAN ranges, known as slices. FSFW acts as a proxy between one or more OpenFlow controllers and a set of switches within a single administrative domain. FSFW only carries OpenFlow commands from a controller to a switch (or the reverse) if the command falls within the allocated range of VLANs for that controller. FSFW acts as a resource protector, ensuring that no controller overconsumes scarce resources such as the rate at which OpenFlow rules can be fed to a switch or the number of OpenFlow entries in the Flow Table. Technology enables Innovation in the Internet2 Community

19 Prototype Multi-Domain Layer 2 Service
Backdrop: Internet2 operates a Layer 2 Service Campuses (e.g. University of Utah) operate a Layer 2 Service Regional Networks (e.g. MAX) operate a Layer 2 Service Exchange Points (e.g. AMPATH/FIU) operate a Layer 2 Service Is there a way to create a Multi-Domain Layer 2 Service? Common capabilities Willingness to collaborate Willingness to contribute to a common project Maintain local control Withdraw at any time Enable (illusion of) global control Control remote administrative domains No change in software, just configuration

20 An SDX is a next generation Independent Exchange Point (IXP)
An SDX is a next generation Independent Exchange Point (IXP). See report from recent GENI workshop.

21 There will be many SDXs (e.g. STARLIGHT, MAN LAN, WIX).

22 You could knit them together with an interdomain protocol like IDCP, NSI, or GENI stitching …
