Value ladder of public
administration
1. Direct return on Investment
2. Indirect RoI via lower own costs for
communication
3. Indirect RoI via tax revenues
4. Indirect RoI via better quality of life
and less costs for social welfare

Open Access, request 2
• Operator-neutral: Connect to the service provider
of your choice
– Departments, universities
– Commercial providers
• Shared access infrastructure to cut costs
• Independent: Anyone can act, noone can block:
first mile rather than last mile

Open Network interfaces
• Empowering different (natural) actors to
build networks together
– Increasing horisontal competition as opposed to
vertical
– Building new value chains
– Exploiting local business models

Exchange point centric
topologies
• As opposed to traditional vertically
integrated operator centric topologies
• Cooperation with real-estate owners,
infrastructure owners and different kinds of
service providers

What about traditional operators?
• Attitude depends on market position
– Incumbents negative
– Second operators positive
– Local entrepreneurs wants it all
(gatekeepers)
• Professional maintenance necessary
• WLAN market slow to take off
• Service level guarantees a concern

What do regulators think?
• Independent regulators are positive
• Less independent regulators often protect
the incumbent

Value chains, actors and business models
• Passive infrastructure owners
– lease physical connections
• Access operators
– operate level 2, charge users for connecting and service
providers
• ISPs operate level 3
– Operate Internet network and application services
• Content providers/distributors
– PSTN gateways (e.g. digisip)
– TV/Video (e.g. CanalDigital)
– Databases, GIS, weather forecasts, games,....
• Users
– pay and consume

voip and Internet services,
• Support for mobility of terminals and
sessions
• Access network issues (AAA, shared access
networks)

Optix
• TSLab is designing a test bed for integration of IPnetworks over optical networks, e.g for protection
switching via Interdomain routing
• Involves IP-routing and GMPLS issues
• Based on two lumentis switches
