2 About BelWü B E L Wü = Baden Württemberg Extended Lan In the first place: designed to connect the Universities to a big LAN Nowadays: network with academic/educational/public participants Participants: Universities, Universities of applied science Smaller institutes, public departements Libraries, student dormitories,... Appr. 1,500 schools via DSL 2 Tim Kleefass BelWü, Baden-Württemberg, Germany

3 BelWü infrastructure As often as possible: Dark fiber with passive-wdms Else, if possible: Wavelength(s) (with passive-wdms) Else: Bandwidth (GE/10GE) 3 Tim Kleefass BelWü, Baden-Württemberg, Germany

5 BelWü infrastructure super-core between nine (big) universites (Several) 10GE w/ 15 * ASR 9010 This year: first 100GE links (?) core betwenn universities of applied science, cooperative state university,... inter-city: 10GE w/ 23 * ASR 9006 intra-city: GE w/ Cisco 2800, 2900 This year: 10GE w/ Cisco ASR 9001 (?) Some Cisco ASR 1001 on stub-links for terminating 10GE Some Cisco ASR 1001 as Firewall/Access-Router Cisco 2800, 2900, 3900 series on smaller sites Catalyst 6500 VSS-system for redundant data-center 5 Tim Kleefass BelWü, Baden-Württemberg, Germany

7 BelWü persons Organisation leader: 1 NOC: 8 (3 backbone, 2 smaller sites, 2 hotline for schools) Systems: 7 (3 Sysadmin, 2 DNS/Mail/NTP/HTTP-proxy, 2 WWW/Moodle support) Administration: 5 (3 Administration, 2 DB) Active monitoring between 06:00-18:00 Other time: oncall (alarms via text and 24/7 emercency phone) Functions: All. Operations, planning,... Except: Bandwidths (of course), sometimes fiber measurements 7 Tim Kleefass BelWü, Baden-Württemberg, Germany

8 BelWü communication and documentation Communication (mainly) Phone Mailinglist for network problems Twitter for (smaller) updates on network problems Documentation Request Tracker Text-Files, Wiki OmniGraffle (dia) Subversion w/ webfrontend (Photos, scanned hand-written papers) 8 Tim Kleefass BelWü, Baden-Württemberg, Germany

9 BelWü network monitoring Dark fiber network (with some bandwidths) We offer IP, no MPLS, no L2-VPNs, etc. (Except: sometimes third party wavelengths) Cisco Router (ASR 1k, 9k, GSR, 2800, 2900, 3900,...) and transceiver sensors AOCtech EDFA Monitoring MRTG for interface counters, Weathermap Smokeping for latency Cacti for EDFAs, some special things Minemon (shell-script for pings) for alarming (network and customers LANs) Rancid for configuration history Nfsen in deployment Some self-written scripts for BGP, CPU,... monitoring 9 Tim Kleefass BelWü, Baden-Württemberg, Germany

FEC, BER-rate via power output OEM SR/LR/ZR XFP, SX/LX/ZX SFP 180 km without amplification between the two end-sites Cool: DWDM C/L-subband-splitter A: ITU-ch B: ITU-ch plus Tim Kleefass BelWü, Baden-Württemberg, Germany
