Technical – On campus
• Originally SOWN was an ad-hoc Mesh network
• Now we have some campus nodes which use iSolutions’ network to talk to the Internet and the rest of SOWN
• Currently there is one high powered node working atop of SUSU
• Run embedded PCs with Voyage Linux or OpenWRT
• High powered (>400mw) miniPCI wifi cards

Technical – Servers• Rack mount servers located in building
32 (EEE)
• sown-auth – does what it says on the tin – This server is our authentication server for Web Redirect and 802.1x. We are directly peered with University login servers and through them to eduroam
• sown-vpn – Responsible for handling back-haul links from remote nodes so that they can talk to auth
• sown-nat – allows access to the internet for users of the on campus nodes and for all machines to update online etc. Also runs SNMP and cacti to make pretty graphs

Technical – More Servers!
• Servers in Zepler
• sown-6core – IPv6 router for SOWN
• sown-7core – More IPv6 development. This server is currently used for Mobile IPv6 testing in ECS and SOWN
• sown-dev – Development server for testing of new technologies. Interesting things like Voice over IP are running on this box

Technical – SOWN[at]HOME
• Plug’n’Play wireless access points to allow SOWN access to be broadcast from users house with the minimum of fuss
• Just plug it in to a free network port on your router and switch on!
• Makes use of home ADSL line for internet access
• Tunnels are set up to sown-vpn so SOWN network access is granted.
• User authentication is passed down the tunnel to sown-auth
• Nodes are made by Meraki, but run with our own flavour of OpenWRT (linux distribution for home routers) which is configured to work with SOWN

We are continually improving the web interface for users and administrators
• Firmware updates
• Package management and configuration
• Security
• We have just spent this summer researching Wireless Security and rolling it out on SOWN
• Long distance wireless research (802.11a and WiMAX)
• Deployment of new technologies: multicast, VoIP, Mobile IPv6 etc…

SOWN Part 2
What are we currently researching?
• WiMAX – we are shortly going to be the second city in the UK with this bleeding edge technology
• Multicast – SOWN TV?
• VoIP – Internet phone in your home
• IP Mobility – ECS and Janet UK are currently developing services in this area. SOWN is integral to this research!
