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
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
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
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
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
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
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
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.

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.
IP3 NetAccess manages Guest Internet Connections
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.

E-mail, VPN,
etc.
Portal groups:
 Combination of the following:
– Assigned (Guest) VLAN
– Assigned (customised) login portal
– Payment method (access code)
– Product (eg 512K bandwidth)

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.

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
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,
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
