1. GEOPRIV Experiment at IETF 71 n Goal: Demonstrate GEOPRIV protocols using the IETF network to provide location l Data formats: PIDF-LO and Civic Address XML schema l Protocols: HELD and XMPP/Jabber n Positioning based on wiremap information l IP – MAC – Access Point – Location n HELD Server acts as a portal for this information n XMPP client pulls location from HELD and posts it as status

2. GEOPRIV Experiment: Positioning n NetDisco server collects information from APs about which MAC addresses they have assigned which IP addresses l When Client connects, AP records the MAC-IP mapping l NetDisco polls at ~5min interval NetDisco HELD LIS Jabber Server Buddy Client AP

3. GEOPRIV Experiment: Request path n Client sends an HTTP request to the Location Information Server to get location n LIS queries a web service on the NetDisco server with the source IP address of the request l GET http://peter/netdisco/public_locate_user.xml?ip=130.129.5.6 HTTP/1.1 n LIS takes location from NetDisco and packages it as a PIDF-LO document within a HELD response NetDisco HELD LIS Jabber Server Buddy Client AP GET

4. GEOPRIV Experiment: Return path NetDisco HELD LIS Jabber Server Buddy Client 200/OK false 2008-03-15T23:50:55+11:00 Wiremap 2008-03-14T23:50:55+11:00 08:00:2b:01:02:03 US Pennsylvania Philadelphia Market Street 1201 NE 4 19107 Franklin 6/7

5. GEOPRIV Experiment: Applications n Location-based applications on the client can now use the location n At the IETF, a sample application posted location as status for an XMPP/Jabber user NetDisco HELD LIS Jabber Server Buddy Client dnd Current location: Room Franklin 6/7, NE Floor 4 1201 Market Street Philadelphia, Pennsylvania, US 19107
