Sponsored by the National Science Foundation 2 March 16th, 2011 Connecting GENI Resources Think outside of the (sand)box –You’ve set up some GENI resources –Connect to other GENI resources http://groups.geni.net/geni/wiki/ConnectivityOverview Why connect? –To make your resources (aggregates) available –Experimenters (faculty, students) are asking –The GPO is asking http://groups.geni.net/geni/wiki/ExperimenterPortal

3. Sponsored by the National Science Foundation 3 March 16th, 2011 Get Yourself Connected! 1.What are you connecting to? - labs, campuses, backbones, etc - resources, aggregates, etc 2.What type of connections are required? 3.Do you require engineering of new connectivity? - Or, can you use existing connectivity? 4.Are you using connectivity services? 1.Backbones 2.Aggregate-controlled stitching 5.Does your connectivity work? This is complex! The GPO will help you find a solution that works best for you and your users. Expect things to get simpler as GENI evolves.

4. Sponsored by the National Science Foundation 4 March 16th, 2011 1. What are you connecting to? What sites are participating? –What resources are available at other sites? Various options listed on the GENI wiki –http://groups.geni.net/geni/wiki/GeniAggregate –http://groups.geni.net/geni/wiki/ConnectivityOptions

5. Sponsored by the National Science Foundation 5 March 16th, 2011 2. Types of connections Layer-3 connectivity (mostly easy) –Commodity Internet –Backbone layer-3 services –Tunneling (including layer-2 over layer-3+) Layer-2 connectivity (focus of this talk) –Static connections (where we are) Intra-campus connections Regional VLANs Backbone VLANs –Aggregate-controlled stitching (where we’re going) OpenFlow ProtoGENI ORCA http://groups.geni.net/geni/wiki/ConnectivityGuidelines

7. Sponsored by the National Science Foundation 7 March 16th, 2011 3.1 Engineering L2 Connections 1.Intra-campus connectivity –Provide connections between your resources different labs, different buildings, etc. –Connect your resources to the edge –Common options are: VLANs Additional physical connectivity

8. Sponsored by the National Science Foundation 8 March 16th, 2011 2.Regional connections –If sites share a regional then the regional may be able to provide connectivity 3.2 Engineering L2 Connections

9. Sponsored by the National Science Foundation 9 March 16th, 2011 3.3 Engineering L2 Connections 3.Backbone connections –Choose your path to your Backbone endpoint –Other sites will need connections to their endpoints as well http://groups.geni.net/geni/wiki/ConnectivityOverview http://groups.geni.net/geni/wiki/ConnectivityGuidelines

10. Sponsored by the National Science Foundation 10 March 16th, 2011 4. Connectivity Services Backbones Focus is layer-2 VLAN connectivity Provides “dynamic” provisioning of connectivity between backbone endpoints Used in a typically static manner Involves a person Current options: Internet2 ION National LambdaRail FrameNet

11. Sponsored by the National Science Foundation 11 March 16th, 2011 Backbones - Internet2 ION Follows a “circuit” model –Point-to-point connections –Supports VLAN translation Your ION endpoint –Looks like: bbn.newy.ion.internet2.edu Circuit provisioning service: ION –Done by Internet2, your regional, your IT staff, or GPO –http://www.internet2.edu/ion/ More info on ION and participating organizations: –http://groups.geni.net/geni/wiki/SiteInternet2

12. Sponsored by the National Science Foundation 12 March 16th, 2011 Backbones – National LambdaRail FrameNet Follows a “VLAN” model –supports multi-point VLANs –VLAN translation via request to NLR. Your FrameNet endpoint –Looks like: bost.layer2.nlr.net[Gi9/2] VLAN provisioning service: Sherpa –Done by NLR, your regional, your IT staff, or GPO –https://sherpa.nlr.net/ More info on FrameNet and Sherpa usage: –http://groups.geni.net/geni/wiki/SiteNlr

14. Sponsored by the National Science Foundation 14 March 16th, 2011 Aggregate-controlled stitching - OpenFlow Core http://groups.geni.net/geni/wiki/NetworkCore Reachable via –Internet2 ION –National LambdaRail FrameNet OpenFlow-controlled interconnections. Considerations: –There are currently two OpenFlow core VLANs (3715, 3716) –Use two VLANs to participate in both OpenFlow Core VLANs –If you share a path to the OpenFlow core with other sites your VLAN IDs must be unique on any shared layer-2 devices OpenFlow Core VLAN 3715 http://www.openflow.org/wp/

17. Sponsored by the National Science Foundation 17 March 16th, 2011 5. Does your connectivity work? Testing your connection –Assign static private IP addresses VLANs encoded as the subnet other subnets may be used by experiments –For multi-site connections, e.g. the OpenFlow core, ranges of IP addresses are “assigned” per site http://groups.geni.net/geni/wiki/ConnectivityHome

18. Sponsored by the National Science Foundation 18 March 16th, 2011 Summary Spiral 3 ops goals: –More interconnected sites with aggregates –Leverage aggregate-controlled stitching (current methods do not scale) Less engineering, more experimenting GPO will help –Check out the wiki for GENI participants, aggregates, experiments, etc http://groups.geni.net/geni http://groups.geni.net/geni/wiki/ExperimenterPortal –Email us with questions! help@geni.net
