The pgeni.gpolab.bbn.com slice authority is used for the credentials and the following aggregate manager nick_names were defined in the omni_config:
#ExoGENI Compute and OF Aggregates Managers exobbn=,https://bbn-hn.exogeni.net:11443/orca/xmlrpc exorci=,https://rci-hn.exogeni.net:11443/orca/xmlrpc exosm=,https://geni.renci.org:11443/orca/xmlrpc of-exobbn=,https://bbn-hn.exogeni.net:3626/foam/gapi/1 of-exorci=,https://rci-hn.exogeni.net:3626/foam/gapi/1 #Meso-scale Compute and OF Aggregates Managers of-bbn=,https://foam.gpolab.bbn.com:3626/foam/gapi/1 of-clemson=,https://foam.clemson.edu:3626/foam/gapi/1 of-i2=,https://foam.net.internet2.edu:3626/foam/gapi/1 of-rutgers=,https://nox.orbit-lab.org:3626/foam/gapi/1 plc-bbn=,http://myplc.gpolab.bbn.com:12346/ plc-clemson=,http://myplc.clemson.edu:12346/ pgeni=,https://pgeni.gpolab.bbn.com/protogeni/xmlrpc/am pg2=,https://www.emulab.net/protogeni/xmlrpc/am/2.0
1. As Experimenter1, request ListResources from BBN ExoGENI, RENCI ExoGENI, and FOAM at NLR Site.
GPO ProtoGENI user credentials for lnevers@bbn.com were used for Experimenter1.
Requested listresources from each of the FOAM aggregates:
$ omni.py listresources -a of-exobbn -o $ omni.py listresources -a of-bbn -o $ omni.py listresources -a of-nlr -o $ omni.py listresources -a of-i2 -o $ omni.py listresources -a of-exorci -o
2. Review ListResources output from all AMs
Requested listresources from each of the GENI AM aggregates:
$ omni.py listresources -a plc-bbn -o $ omni.py listresources -a plc-clemson -o $ omni.py listresources -a pg2 --api-version 2 -t GENI 3 -o $ omni.py listresources -a exobbn -o $ omni.py listresources -a exorci -o
3. Define a request RSpec for a VM at the BBN ExoGENI.
Defined an RSpec for one VM on the shared VLAN 1750 in the BBN ExoGENI rack: EG-EXP-6-exp1-exobbn.rspec
4. Define a request RSpec for a VM at the RENCI ExoGENI.
Define an RSpec for one VM on the shared VLAN 1750 in the RENCI ExoGENI rack: EG-EXP-6-exp1-exorci.rspec
5. Define request RSpecs for OpenFlow resources from BBN FOAM to access GENI OpenFlow core resources.
Defined an OpenFlow RSpec for the FOAM controllers in each rack:
- BBN Rack RSpec: EG-EXP-6-exp1-openflow-exobbn.rspec
- RENCI Rack RSpec: EG-EXP-6-exp1-openflow-exorci.rspec
The BBN ExoGENI rack connects to the GENI backbone via the BBN GPO Lab OpenFlow switch named poblano. In order for this scenario to work OpenFlow must be configured also on the poblano switch to allow the BBN ExoGENI rack OF traffic to get to the OF GENI core. The following OpenFlow RSpec was defined for the BBN site switch poblano: EG-EXP-6-exp1-openflow-bbn.rspec
6. Define request RSpecs for OpenFlow core resources at NLR FOAM.
Defined an OpenFlow RSpec for the NLR FOAM controller: EG-EXP-6-exp1-openflow-nlr.rspec
7. Create the first slice
Created the first slice:
$ omni.py createslice EG-EXP-6-exp1
8. Create a sliver in the first slice at each AM, using the RSpecs defined above.
$ omni.py -a exobbn createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-exobbn.rspec $ omni.py -a of-exobbn createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-openflow-exobbn.rspec $ omni.py -a of-bbn createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-openflow-bbn.rspec $ omni.py -a of-nlr createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-openflow-nlr.rspec $ omni.py -a of-exorci createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-openflow-exorci.rspec $ omni.py -a exorci createsliver EG-EXP-6-exp1 EG-EXP-6-exp1-exorci.rspec
Here are of the Rspecs used: EG-EXP-6-exp1-exobbn.rspec, EG-EXP-6-exp1-openflow-bbn.rspec, EG-EXP-6-exp1-openflow-nlr.rspec, and EG-EXP-6-exp1-exorci.rspec.
9. Log in to each of the systems, verify IP address assignment. Send traffic to the other system, leave traffic running.
Determine the status of the OpenFlow slivers, check the sliverstatus for each to make sure that they have been approved. Note that 'geni_status' is 'ready' when the sliver is approved. If the OpenFlow sliver is waiting for approval the 'geni_status' will be 'configuring:
$ omni.py -a of-bbn sliverstatus EG-EXP-6-exp1 $ omni.py -a of-nlr sliverstatus EG-EXP-6-exp1
Determine compute resources allocated to each sliver in the ExoGENI racks. First make sure the sliverstatus is ready:
$ omni.py -a exobbn sliverstatus EG-EXP-6-exp1 $ omni.py -a exorci sliverstatus EG-EXP-6-exp1
Once the slivers are ready get the list of hosts allocated with Omni:
$ omni.py -a exobbn listresources EG-EXP-6-exp1 -o $ omni.py -a exorci listresources EG-EXP-6-exp1 -o $ egrep hostname EG-EXP-6-exp1-rspec-bbn-hn-exogeni-net-11443-orca.xml <login authentication="ssh-keys" hostname="192.1.242.6" port="22" username="root"/> $ egrep hostname EG-EXP-6-exp1-rspec-rci-hn-exogeni-net-11443-orca.xml <login authentication="ssh-keys" hostname="152.54.14.13" port="22" username="root"/>

10. As Experimenter2, define a request RSpec for one VM and one bare metal node at BBN ExoGENI.
GPO ProtoGENI user credentials for lnevers1@bbn.com were used for Experimenter2.
Requested listresources from each of the FOAM aggregates:
$ omni.py listresources -a of-exobbn -o $ omni.py listresources -a of-bbn -o $ omni.py listresources -a of-nlr -o $ omni.py listresources -a of-exorci -o
Requested listresources from each of the ExoGENI aggregates:
$ omni.py listresources -a exobbn -o $ omni.py listresources -a exorci -o
Defined an RSpec for one VM and one bare metal node on the shared VLAN 1750 in the BBN ExoGENI rack EG-EXP-6-exp2-exobbn.rspec. Attached as a reference, even though it could not be used for this test case as described.
The Bare Metal node is only available via the ExoSM, so in order to preserve the requests to the individual AMs, modified the RSpec to use 2 VMs, and the new RSpec used is EG-EXP-6-exp2-exobbn-mod.rspec.
11. Define a request RSpec for two VMs on the same worker node at RENCI ExoGENI.
Defined an RSpec for two VMs on the shared VLAN 1750 in the RENCI rack: EG-EXP-6-exp2-exorci.rspec
12. Define request RSpecs for OpenFlow resources from GPO FOAM to access GENI OpenFlow core resources.
The experiment uses the flows defined by the RSpec EG-EXP-6-exp2-openflow-bbn.rspec.
13. Define request RSpecs for OpenFlow core resources at NLR FOAM
The experiment uses the flows defined by the previous experiment, as defined in EG-EXP-6-exp2-openflow-nlr.rspec
14. Create a second slice
$ omni.py createslice EG-EXP-6-exp2
15. Create a sliver in the second slice at each AM, using the RSpecs defined above
Because of the issues described in step 10, had to request to VMs on the shared VLAN 1750 at the BBN SM. The request:
$ omni.py -a exobbn createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-exobbn-mod.rspec
Created a sliver at RENCI ExoGENIrack aggregate:
$ omni.py -a exorci createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-exorci.rspec
Create a sliver for the network resources required by experiment 2:
$ omni.py -a of-exobbn createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-openflow-exobbn.rspec $ omni.py -a of-bbn createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-openflow-bbn.rspec $ omni.py -a of-nlr createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-openflow-nlr.rspec $ omni.py -a of-exorci createsliver EG-EXP-6-exp2 EG-EXP-6-exp2-openflow-exorci.rspec
16. Log in to each of the systems in the slice
Login to each system and send traffic to each other systems; leave traffic running.
Determine compute resources allocated to each sliver in the ExoGENI racks. First make sure the sliverstatus is ready:
$ omni.py -a exobbn sliverstatus EG-EXP-6-exp2 $ omni.py -a exorci sliverstatus EG-EXP-6-exp2
Once the slivers are ready get the list of hosts allocated with Omni:
$ omni.py -a exobbn listresources EG-EXP-6-exp2 -o $ omni.py -a exorci listresources EG-EXP-6-exp2 -o $ egrep hostname EG-EXP-6-exp2-rspec-bbn-hn-exogeni-net-11443-orca.xml <login authentication="ssh-keys" hostname="192.1.242.8" port="22" username="root"/> <login authentication="ssh-keys" hostname="192.1.242.7" port="22" username="root"/> $ egrep hostname EG-EXP-6-exp2-rspec-rci-hn-exogeni-net-11443-orca.xml <login authentication="ssh-keys" hostname="152.54.14.16" port="22" username="root"/> <login authentication="ssh-keys" hostname="152.54.14.14" port="22" username="root"/>

$ omni.py listresources -a exobbn -o $ omni.py listresources -a of-bbn -o $ omni.py listresources -a of-i2 -o $ omni.py listresources -a of-rutgers -o $ omni.py listresources -a pgeni -o $ omni.py listresources -a pg2 --api-version 2 -t GENI 3 -o
18. Review ListResources output from all AMs
Reviewed content of advertisement RSpecs for each of the aggregates polled in the previous step.
19. Define a request RSpec for a VM at the BBN ExoGENI
Defined RSpec for one VM on the shared VLAN 1750 in the BBN ExoGENI rack: EG-EXP-6-exp3-exobbn.rspec
20. Define a request RSpec for a compute resource at the GPO Meso-scale site
Defined RSpec for one PG Resource at the GPO PG site: EG-EXP-6-exp3-bbn-pgeni.rspec
21. Define a request RSpec for a compute resource at a Meso-scale site
Defined RSpec for one WAPG Resource at the Rutgers site EG-EXP-6-exp3-rutgers-wapg.rspec
22. Define request RSpecs for OpenFlow resources to allow connection from OF BBN ExoGENI to Meso-scale OF sites GPO (NLR) and Rutgers Sites (I2)
Defined the OpenFlow RSpecs for the sites below, note that the BBN OF RSpec overlaps with the one in experiment 1 and is being used here:
- Rutgers EG-EXP-6-exp3-openflow-rutgers.rspec
- BBN [EG-EXP-6-exp3-openflow-bbn.rspec]
- Internet2 EG-EXP-6-exp3-openflow-i2.rspec
23. Create a third slice
$ omni.py createslice EG-EXP-6-exp3
24. Create sliver that connects the Internet2 Meso-scale OpenFlow site to the BBN ExoGENI Site, and the GPO Meso-scale site
Requests are as follows:
$ omni.py -a exobbn createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-exobbn.rspec $ omni.py -a of-exobbn createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-openflow-exobbn.rspec $ omni.py -a pgeni createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-bbn-pgeni.rspec ## See Note1 $ omni.py -a of-bbn createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-openflow-bbn.rspec $ omni.py -a of-i2 createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-openflow-i2.rspec $ omni.py -a pg2 createsliver EG-EXP-6-exp3 --api-version 2 -t GENI 3 EG-EXP-6-exp3-rutgers-wapg.rspec ## Both WAPG not available $ omni.py -a of-rutgers createsliver EG-EXP-6-exp3 EG-EXP-6-exp3-openflow-rutgers.rspec
Note: The GPO ProtoGENI reservation must be requested before the BBN OpenFlow FOAM request. This must be done to determine the port of the GPO PG node assigned, and then configure the BBN FOAM RSpec accordingly.
25. Log in to each of the compute resources in the slice
Determine which compute resources are allocated to the sliver in the BBN ExoGENI rack. First make sure the sliverstatus is ready, then when the sliver is ready get the host allocated with Omni:
$ omni.py -a exobbn sliverstatus EG-EXP-6-exp3 $ omni.py -a exobbn listresources EG-EXP-6-exp3 -o $ egrep hostname EG-EXP-6-exp3-rspec-bbn-hn-exogeni-net-11443-orca.xml <login authentication="ssh-keys" hostname="192.1.242.9" port="22" username="root"/>
Determine the resources allocated to the WAPG Rutgers node:
$ omni.py -a pg2 sliverstatus EG-EXP-6-exp3 --api-version 2 -t GENI 3 -o
Determine the resources allocated to the GPO PG node:
$ omni.py -a pgeni sliverstatus EG-EXP-6-exp3 $ omni.py -a pgeni listresources EG-EXP-6-exp3 -o $ egrep "hostname" EG-EXP-6-exp3-rspec-pgeni-gpolab-bbn-com.xml <login authentication="ssh-keys" hostname="pc9.pgeni.gpolab.bbn.com" port="22" username="lnevers"/>

27. Review baseline, GMOC, and monitoring statistics
Initial plan for this step was to review the slice monitoring data at GMOC DB location, but after discussion with ExoGENI team, this step is being modified to use Iperf to determine statistics for the experimenter.
Iperf Run-1
As Experimenter1 (lnevers), ran Iperf from the BBN host to the RENCI host in Experiment 1, with other 2 experiments (2&3) idle, with these results:
root@debian:~# iperf -c 10.42.19.25 ------------------------------------------------------------ Client connecting to 10.42.19.25, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 10.42.19.27 port 36977 connected with 10.42.19.25 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.1 sec 5.77 MBytes 4.81 Mbits/sec
Iperf Run-2
As Experimenter2 (lnevers), ran Iperf concurrently from the each of the two BBN hosts to the two RENCI hosts in Experiment 2, with other 2 experiments (1 & 3) idle, with these results on the first BBN host:
root@debian:~# iperf -c 10.42.18.15 ------------------------------------------------------------ Client connecting to 10.42.18.15, TCP port 5001 TCP window size: 16.0 KByte (default) ------------------------------------------------------------ [ 3] local 10.42.18.98 port 42409 connected with 10.42.18.15 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0-10.0 sec 5.83 MBytes 4.87 Mbits/sec

29. As Experimenter3, verify that traffic only flows on the network resources assigned to slivers as specified by the controller
From Experimenter 3 host attempted to connect to Experimenter 2 host:
$ ssh 192.1.242.9 -l root root@debian:~# ifconfig eth1 eth1 Link encap:Ethernet HWaddr 52:54:00:e6:5e:1a inet addr:10.42.11.198 Bcast:10.42.255.255 Mask:255.255.0.0 inet6 addr: fe80::5054:ff:fee6:5e1a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2668 errors:0 dropped:0 overruns:0 frame:0 TX packets:731 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:167664 (163.7 KiB) TX bytes:30918 (30.1 KiB) root@debian:~# ping 10.42.18.15 PING 10.42.18.15 (10.42.18.15) 56(84) bytes of data.

30. Verify control access to OF experiment
Verify that no default controller, switch fail-open behavior, or other resource other than experimenters' controllers, can control how traffic flows on network resources assigned to experimenters' slivers.
The following scenarios were verified:
- Traffic is not exchanged when the controller is not running.
- Starting controller allows existing traffic flows to be delivered.
- Stopping the controller does not stop an existing continuous traffic exchange.
- Stopping the controller and starting a flow within the default timeout (5 sec) allow traffic delivery.
- Stopping the controller and starting a flow after the default timeout (5 sec) does not allow traffic delivery..
31. Set the hard and soft timeout of flowtable entries
The flow timeout scenarios were verified by modifying the "idle_timeout" from "0" to "15" seconds and modifying the "hard_timeout" from "0" to 40 seconds in the file src/nox/coreapps/switch/switch.cc:
- Stopping the controller and starting a flow within the "hard_timeout" (15 sec) allow traffic delivery.
- Stopping the controller and starting a flow after the "hard_timeout" (40 sec) does not allow traffic delivery.
32. Get switch statistics and flowtable entries for slivers from the OpenFlow switch.
Statistics can be collected by experimenters and by administrator. In this step verified that both are possible.
Statistics available to Experimenters
In this step the FloodLight Controller is used to capture statistics rather than the NOX Controller as shown in earlier steps. The Floodlight controller was configured to run on port 33020. The following is a list of switches associated with floodlight that is running as a controller for EG-EXP-6-exp3:
$ curl http://localhost:9090/wm/core/controller/switches/json [{"dpid":"00:00:0e:84:40:39:18:1b"},{"dpid":"06:d6:00:24:a8:c4:b9:00"}, {"dpid":"00:00:0e:84:40:39:19:96"},{"dpid":"00:00:0e:84:40:39:1b:93"}, {"dpid":"00:00:0e:84:40:39:18:58"},{"dpid":"00:00:0e:84:40:39:1a:57"}, {"dpid":"00:01:08:17:f4:b5:2a:00"},{"dpid":"06:d6:00:12:e2:b8:a5:d0"}, {"dpid":"00:00:00:10:10:17:50:01"}]
Note: The ExoGENI DPID is "00:01:08:17:f4:b5:2a:00"
These are switch statistics for the ExoGENI Switch, note that ports showing no statistics were omitted to simplify output captured:

Statics for ports '42' and '64' are of interest as shown by the details in the flow tables for the ExoGENI OF Switch. The flows between the 2 nodes 10.42.11.209 (pc9.pgeni.gpolab.bbn.com) and the address 10.42.11.198 *ExoGENI VM on shared VLAN 1750) are shown in this lists of flows on the ExoGENI switch:

The head node runs the FlowVisor for the OpenFlow switch in the ExoGENI rack. To access switch and slice statistics a login on head node in the ExoGENI rack is required, this is not normally available to experimenters. This scenarios was executed using NOX as a controller for the slice EG-EXP-6-exp3.
Determined how many slices were running according to FlowVisor:
[lnevers@bbn-hn ~]$ /opt/flowvisor/bin/fvctl --passwd-file=/opt/flowvisor/etc/flowvisor/fvpasswd listSlices Slice 0: f08d3095-1c80-4d13-bb55-77fe60cc2743 Slice 1: 21095873-0df9-4254-ba15-9af4e817d3a2 Slice 2: fvadmin Slice 3: 4a1d909c-b0c7-45a7-b100-01e0b1d8bd3a Slice 4: 8aad0aae-ae92-4a3c-bd5e-43f7456f628e Slice 5: 013f6aa7-e600-4be5-9e31-5c0436223dfd Slice 6: e10d67f9-4680-4774-9968-aae42c8fdccb
In this example, we will be looking for the FlowVisor Slice associated with EG-EXP-6-exp3. So we have to show the slice information for each of the above to determine which is one that maps to EG-EXP-6-exp3.

Now that we have identified the slice, we can get statistics for it:

34. Install flows that match on layer 2 fields and/or layer 3 fields.
35. Run test for at least 4 hours
36. Review monitoring statistics and checks as above
Initial plan for this step was to review the slice monitoring data at GMOC DB location, but after discussion with ExoGENI team, this step is being modified to use Iperf to determine statistics for the experimenter.
First checked performance for the nodes in EG-EXP-6-exp3, endpoints are one ExoGENI VM and one GPO ProtoGENI meso-scale node (pc9), following are the results reported on the ExoGENI iperf server:

These are the results from the client iperf running on the GPO ProtoGENI node pc9:
