Agenda ➢ Topology overview ➢ Network services ➢ Case studies ➢ Future MeDiMed ICN 2006CEF Networks Prague 2006

Topology MeDiMed ICN 2006CEF Networks Prague 2006

Metropolitan Networks ➢ Small and Mid-size Networks ➢ Prague ➢ Brno MeDiMed ICN 2006CEF Networks Prague 2006

Metropolitan Networks ➢ Beginning ➢ Evolution Ethernet -> ATM -> GE ➢ Fibre optics mostly in ownership of universities ➢ Primarily for academic networking MeDiMed ICN 2006CEF Networks Prague 2006

Network Services Network services provided by metropolitan networks: ➢ Internet ➢ IPv4 multicast ➢ IPv6 ➢ E2E connection MeDiMed ICN 2006CEF Networks Prague 2006

Network Services Additional network services needed: ➢ Voice services ➢ Next generation (multimedia) services ➢ Commodity IP ➢ Dedicated virtual networks for developing applications MeDiMed ICN 2006CEF Networks Prague 2006

Multi-service in first mile ➢ Usually per application solution ➢ Low penetration of next-generation services ➢ In some sense technical solution of non-technical problems ➢ State of Internet deployment in central Europe MeDiMed ICN 2006CEF Networks Prague 2006

Case studies Brno University of Technology ➢ Goal: offer of commercial internet to student's hostels ➢ Student's hostels at 4 locations ➢ Total about 5000 users ➢ GE connectivity to university network ➢ Small fee for connection MeDiMed ICN 2006CEF Networks Prague 2006

Case studies Brno University of Technology ➢ Some applications don't fulfill AUP ➢ Partially commercial accommodation ➢ Some rooms used by commercial entities ➢ Solved mostly by “brutal force” approach – parallel network infrastructure MeDiMed ICN 2006CEF Networks Prague 2006

Case studies PASNET ➢ Legal entity offering both academic and commodity internet ➢ Mostly leased fibre optics used ➢ CWDM MeDiMed ICN 2006CEF Networks Prague 2006

Case studies Technical University of Ostrava ➢ Sharing network infrastructure with CZFree project ➢ Used for WiFi connectivity ➢ Sharing transport infrastructure ➢ MPLS based solution MeDiMed ICN 2006CEF Networks Prague 2006

Future ➢ Internet becoming general widely deployed utility ➢ Price and bandwidth going right way ➢ Some reasons for multi-service first mile may disappear ➢ Next-generation applications like IPTV developing slowly MeDiMed ICN 2006CEF Networks Prague 2006
