11 Control a slice of the national network! Enable: Rapid prototyping of advanced applications Rapid prototyping of new network services Rapid advancement of network research

12 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 Network Virtualization on Internet2

13 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. Network Virtualization Use Case

14 Production Service Staging – 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 Use Case Examples (1)

15 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 Use Case Examples (2)

16 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 Technology behind Network Virtualization

19 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 Prototype Multi-Domain Layer 2 Service
