Enabling GENI Connections Quilt GENI Workshop Heidi Picher Dempsey [email protected] July 22, 2010.

Regional and Campus GENI• Many projects with different needshttp://groups.geni.net/geni/wiki/SpiralTwoand /GEC8DemoSummary• All projects eventually enable experiments

between researchers and infrastructure spanning multiple locations (usually campuses)

• Most separate control, data, instrumentation planes

• Notable exceptions like Million Node GENI (may not be exceptions in the long run)

http://groups.geni.net/geni/wiki/MillionNodeGENI

• Network protocol experimentation makes layer 2 connections important for many projects

• GENI campus connections in Spiral2 mostly 1Gbps, some 10Gbps, but will grow quickly.

• About 75% of Quilt members already support GENI projects. Role of regionals expanding (e.g. GENI racks)

Meso-Scale in the backbones • Internet2 and NLR installing 5 OpenFlow switches in

each backbone (HP ProCurve and possibly a second vendor)

• NLR 3-node backbone live for GEC8 demo

• ProtoGENI installing additional nodes (2 or more) in Internet2 and integrating prototype OpenFlow

• GENI layer 2 data planes starting to appear across backbones, regionals and campuses

– ION, FrameNet and custom network engineering "stitching" VLANs

– ORCA, IGENI demonstrating dynamic VLANs at GECs

– NLR and I2 10Gpbs layer2 interconnect at Atlanta

• ShadowNet: installing 3 Juniper M7i routers for measurements in I2 PoPs this year

MesoScale in the Regionals• Plain old IP

• Tunneling above layer 2 (GRE, OpenVPN)

• Layer 2

– Single VLAN (801.q tagged)

– VLAN translation (Supported in ION, not Sherpa/FrameNet)

– Layer 2 tunneling (MPLS, QinQ) (DRAGON, OpenFlow)

– Direct fiber to NLR or I2 backbone (ION, FrameNet)

– Access via FrameNet/ION procedures (duration, bw limits,first-come first-served)

• More info (how-tos, track connections, references)

MesoScale in the Regionals (cont)

• International

– GpENI

– iGENI (Starlight)

– K-GENI (Korea/Indiana only)

– ORBIT (Australia only)

– PrimoGENI (Brazil)

– Others brewing

• Mobile/Wireless (over L2 or IP at regional)

– WiMAx

– OpenFlow WiFi (Openroads)

•MAX, GpENI, TIED projects (may be others)•Dynamic resource allocation via GMPLS-enabled control plane•MAX supports sliced edge compute resources (myPLC) and network virtualization with a GENI Aggregate Manager•Layer 2 Ethernet switches with dedicated 1 GbE and 10GbE connections•Layer 3 IP (management, control and general connectivity)• Programmable network hardware — NetFPGA card installed in rack mounted PC o acts as OpenFlow switch, programmable router, packet generator, etc. o offers advanced measurement capabilities

ProtoGENI and ORCA

• ProtoGENI backbone (5 locations in I2)

– Current nodes on 10 GE dedicated connections to Infinera GENI wave

– Moving to 1 GE ION links between nodes in August (stay tuned)

– Campuses access via IP, ION or dedicated layer2 (through regional)

• ORCA clearinghouse uses NLR backbone in Spiral 2

– Campuses connect via FrameNet, iGENI, and regional optical networks

– Dynamic VLAN allocation

– ORCA broker plans to eventually support many mixed connection types
