1. Introduction  Trinity guest network project objective  College wireless network overview  Public wireless/hospitality internet access  Guest network access challenges  Guest access solution  IP3 NetAccess subscriber gateway  Outcomes and future developments

2. Trinity Guest Network Project  Objective: To facilitate the connection of short stay authorized Guests to the College data wireless (mandatory) and wired (desirable) network.  Examples of authorised Guests: - Conference delegates - Visiting academics and Library readers - VIPs, sales representatives, contractors - Summer accommodation visitors

3. College wireless network overview  Size and locations –750 users last academic year –Approx 145 APs in 50 locations, main Campus, St James, Dartry, D’Olier Street, Foster Place/College Green complex

4. College wireless network overview (cont)  Enterprise class based on Cisco Structured Wireless Aware Network (SWAN).  Secure –802.1X/EAP authentication via Radius/AD –Dynamic 128bit encryption –MAC address registration –VLAN’ed  Clients –802.1X compatible –College AD domain, OS patches, AV, high support  Internet connectivity limited, LAN based services available

5. Public wireless hotspots/Hospitality Guest Internet access  Low security  Any wireless client adapter will connect  Little wireless client configuration to connect  Full or almost full internet access  Connection established using a prepaid access code or credit card via a web based login portal  Connectivity and session management is usually controlled by a wireless gateway device providing a reliable controlled connection

6. Guest network access challenge  To provide an reliable network service to guests with the following characteristics –Low client configuration –Access code/portal authentication –Compatibility for most hardware and software types –Low user support requirements –Feature rich in terms of internet availability  Benefit from existing extensive infrastructure  Protect College’s other data networks and reputation from intentional/unintentional misuse of guest network

7. Guest access solution  Provide public wireless hotspot/hospitality type connectivity features using the existing campus network infrastructure  This is achieved by “overlaying” a Guest enabled network on the existing campus network using VLAN technology and an internet gateway device  A number of internet gateway devices were evaluated

8. Devices evaluated:  Bluesocket WG5000 wireless gateway (August 2004). www.bluesocket.com  Cisco Building Broadband Services Manager (BBSM) ver 5.3. (May 2005). www.cisco.com  IP3 NetAccess NA1500 internet gateway (July 2005). www.ip3networks.com www.ip3networks.com

9. Primary evaluation criteria:  VLAN based guest client discovery*.  Ability to generate its own access codes to facilitate Guest authentication*.  Session and bandwidth control, logging and accounting.  Ease of integration with existing campus network infrastructure, must support min. 1000+ users.  Customisable login portals, DHCP (NAT/PAT),SMTP, support for RADIUS authentication.

10. Evaluation Outcome: Bluesocket WG 5000 Cisco BBSM 5.3 IP3 NA1500 NetAccess VLAN based client discovery* YESNOYES Ability to generate own access codes* NOYESYES All other features YESYESYES

11. IP3 Enterprise Network Firewall Guest overlay architecture Wired Guest (VLAN 14) Wired Staff/Student etc Wireless Guest (VLAN 14), Authentication: OPEN Wireless Staff/Student Authentication 802.1X/EAP Internet IDS appliance

12. IP3 NetAccess subscriber gateway Access Control, Billing, and Subscriber Management Solution  Flash-based Network Appliance  802.1Q VLAN support.  Internal Access Code Generation & Authentication  Custom Login Portals.  Integrated DHCP, Firewall, & Web Servers  RADIUS AAA support  Supports VPN Pass-Through.

13. 1. Guest connects to wired/wireless network, (SSID: TCDguest) 2. Guest client obtains DHCP assigned private IP address, opens Web browser, IP3 redirects to custom login screen. 3. Guest enters guest access code 4. IP3 provides authentication & accounting 5. IP3 manages bandwidth, access code duration. IP3 NetAccess manages Guest Internet Connections Internet, E-mail, VPN, etc. IP3 NetAccess

14. Portal groups:  Combination of the following: –Assigned (Guest) VLAN –Assigned (customised) login portal –Payment method (access code) –Product (eg 512K bandwidth)

23. Access codes - overview:  Created using access code generator.  Codes may be valid between a fixed start/end date or allow a one-off session from time of activation.  The generated access codes can be exported from the IP3 appliance in.CSV format.  The exported codes are then merged with a customised TCD access code token template before printing.  Codes are printed from a standard LaserJet colour printer using Avery business card labels.

27. Outcomes  Over 500 guest users have been facilitated since the system was rolled out in August 2005 –First trial end July, Maths Lattice conference (55) –Production end Aug, Eurographics 2005 (>200) –Sept., BA conference (BA press users fallback) –Sept., EDNO, Maths, Nursing Studies –many individual requests

28. Outcomes (cont) I wanted to say that the wireless access in the printing house worked flawlessly yesterday. Our international evaluation panel and the SFI and IDA minders plugged in, retrieved their e-mail and I think this helped enormously in getting across an image of a professional organization with it's act together. One of the panellists from a University in the South of England commented that he'd never be able to get this kind of service in his home University!. So the day was a big success from our point of view..Thanks Again,

29. Future Developments  There has been much interest from the College community in this new service, strong demand is anticipated during 05/06 academic year  Automate process of distributing access codes  Using other authentication methods and additional VLAN’s to provide: – Quarantine/basic services network – PDA and handhelds – Facilitate Eduroam visitors
