Multi-vendor and multiservice utilisation of first mile of czech academic networks. Karel Slavicek, Ales Houda, Josef Verich, Vladimir Zahorik CEF Networks Prague 2006 Agenda Topology overview ➢ Network services ➢ Case studies ➢ Future ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Topology CEF MeDiMed Networks Prague ICN 2006 2006 Metropolitan Networks Small and Mid-size Networks ➢ Prague ➢ Brno ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Metropolitan Networks Beginning 1993 - 1995 ➢ Evolution Ethernet -> ATM -> GE ➢ Fibre optics mostly in ownership of universities ➢ Primarily for academic networking ➢ CEF MeDiMed Networks Prague ICN 2006 2006 CEF MeDiMed Networks Prague ICN 2006 2006 CEF MeDiMed Networks Prague ICN 2006 2006 CEF MeDiMed Networks Prague ICN 2006 2006 CEF MeDiMed Networks Prague ICN 2006 2006 Network Services Network services provided by metropolitan networks: Internet ➢ IPv4 multicast ➢ IPv6 ➢ E2E connection ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Network Services Additional network services needed: Voice services ➢ Next generation (multimedia) services ➢ Commodity IP ➢ Dedicated virtual networks for developing applications ➢ CEF MeDiMed Networks Prague ICN 2006 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 ➢ CEF MeDiMed Networks Prague ICN 2006 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 ➢ CEF MeDiMed Networks Prague ICN 2006 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 ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Case studies PASNET Legal entity offering both academic and commodity internet ➢ Mostly leased fibre optics used ➢ CWDM ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Case studies Technical University of Ostrava Sharing network infrastructure with CZFree project ➢ Used for WiFi connectivity ➢ Sharing transport infrastructure ➢ MPLS based solution ➢ CEF MeDiMed Networks Prague ICN 2006 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 ➢ CEF MeDiMed Networks Prague ICN 2006 2006 Thank for your attention Questions and comments?
