+ * NYU Poly configuration:  [[BR]]
+ * 1) physical host acting as base station controller, runs the asn-gw and wimaxrf AM. [[BR]]
+  * (1) and (2) run Ubuntu, (3) runs Windows.  [[BR]]
+  * It has Ethernet connections to the NEC IDU, NYU-Poly network (and Internet), and very soon GENI backbone (campus IS just informed me that they will be testing that tomorrow).  [[BR]]
+  * We have firewall rules set up so this host only accepts traffic from host (2) on the wimaxrf AM port. This allows us to make sure that only users with a current reservation can configure the BS. [[BR]]
+ * 2) physical host running OMF 5.3 AM, EC, and some other services that are useful for the testbed. [[BR]]
+  * (1) and (2) run Ubuntu, (3) runs Windows.  [[BR]]
+  * It has Ethernet connections to NYU-Poly network (internet) and OMF control network.  [[BR]]
+  * This is the host that testbed users log on to. We have firewall rules set up on this host so that only users with a current reservation can configure the BS or communicate with the testbed nodes. [[BR]]
+ * 3) physical host that serves our group website and the reservation system for the testbed. It's connected to the NYU-Poly network (and Internet)  [[BR]]
+  * (1) and (2) run Ubuntu, (3) runs Windows. [[BR]]
+ * Our testbed nodes are scattered throughout several CS labs and research areas (not part of our group).  [[BR]]
+  * They are connected to the pre-existing Ethernet jacks in the walls and floors of those rooms, which all go back to a CS server room, where we patch them through to our own (non-openflow) switch for the control network. [[BR]]
+  * We do have an openflow switch that we plan to deploy somewhere at some point. [[BR]]
+ * BBN experience  (need summary)  [[BR]]
+ * [http://groups.geni.net/geni/attachment/wiki/GEC14Agenda/WiMAXDeploymentsAndExperiments/vmsetup_at_uwmadison.pdf Wisconsin configuration] [[BR]]

+  * Also expctl, resctl, and xmpp on same machine [[BR]]
+  * Eth0 (128.105.22.xxx): bridged interface to university network [[BR]]
+  * Eth1 (10.0.0.200): bridged interface to control network [[BR]]
+ * Coming:  plan to federate with ProtoGENI cluster  [[BR]]
+  *  Reference: [http://www.tridentcom.org/2012/program  TridentCom 2012]  :  "Federating wired and wireless test facilities through Emulab and OMF: the iLab.t use case", Stefan Bouckaert (IBBT - Ghent University)  [[BR]]
+  *  BBN is exploring how to utilize this to better integrate WiMAX sites into GENI, and be able to utilize the GENI AM API to assgin resources.  [[BR]]

+=== 2.8)  Roaming Mobile Station using Android Handset ===
+:50pm  [[BR]]
+Harry Mussman (GPO)[[BR]]
+ * Summary of discussions with Sprint about unlocked HTC Evo handset  [[BR]]
+  * Must be unlocked by Sprint, so can register with GENI network  [BR]]
+  * Perhaps:  500 handsets, purchased by Rutgers WINLAB, approx $500 per handset, and distributed to sites  [[BR]]
+  * Harry reports:  waiting for 3-way NDA to be signed, so that we can resume discussions with Sprint  [[BR]]
+  * Need to poll sites for interest  [[BR]]
+ *  Also possible:  Sprint MVNO arrangement for pay-as-you-go data service  [[BR]]
+  * Harry reports:  waiting for 3-way NDA to be signed, so that we can resume discussions with Sprint  [[BR]]
+  * Need to poll sites for interest   [[BR]]
+ * Comments from Matt Sanders (Georgia Tech), who attended the WiMAX meeting  [[BR]]
+  * Along with other jobs, he reports to the CTO, and is campus wireless services manager.    [[BR]]
+  * He has extensive experience negotiating with carriers (and I believe Sprint).  [[BR]]
+  * We talked for some time, and he agreed to advise us as we continue our discussions with Sprint.  [[BR]]
+ * His comments:  [[BR]]
+  * 1)  Sprint has multiple approaches to dealing with “enterprise customers”.  One approach we might consider, for 3G/4G service: “Access Point Node”  (APN), where designated mobile stations (typically associated with an enterprise) are assigned certain IP addresses, so that their traffic can be routed directly to the enterprise. (This is likely to be in a different business unit that the MVNO approach)  [[BR]]
+  * 2)  Matt has a contact at HTC.  He feels that they might well be willing to make a batch of Evos for us.  We would have to talk with them to understand the minimum quantity.
