2 Baden-Württemberg Extended LAN Academic Network of the Federal State of Baden-Württemberg, Germany We are connecting: 9 Universities 47 Universities for applied sciences, etc. Numerous schools, libraries, student dormitories and other institutes And offering services (mostly for Schools): Webhosting (e.g. Moodle e-learning) and youth protection HTTP proxy , SPAM detection Network services (DNS, NTP,...) 2

5 Updates for BelWü Long-run contract (3*5 y) with bandwidth and fibre provider ends in 2016 BelWü No more rented bandwidths => continuos & redundant fibre-only network (New) Optical network For transport between cities (amp, comp, mux, route, ) For by-passing IP routers and backhauling (less IP router) For bandwidths between participants 100G IP access to participants Outsourcing of (some) remote hands and field services Start of roll-out: 1st of March,

7 Campus Optical - today Nicht eingezeichnet: Dispersionskompensation

8 ROADM directed/colored

9 ROADM direction-less/color-less

10 Optical Network Prices for 100G (optical and IP) should drop later this year Lots of vendors will release second generation of line-cards/interface Smaller chips, more 100G port per line-card ROADM prices are quite payable Big vendors are not creative or do not understand us Hardware often quite the same Some differences, e.g., if vendor offers Layer 2 cards (MPLS or Ethernet aggregations) Big differences in software for Planing and NMS tools 10

11 Optical Network If 10G waves Then Compensation necessary If FlexGrid Then Compensation must not be channelized If Compensation fiber Then +25% latency Else Use non-channelized FBG from Proximion Feedback, anybody: FlexGrid + FBG from Proximion? 11

13 2 IP routers and fibre cuts 2.#Spalte:#Unterbruch#Stuttgart#3#Tübingen Entfernungen#auf#der#Glasfaser bis$200 ab$200 ab$500 Router$in:$ Stuttgart,#Karlsruhe RZ RZ West RZ RZ RZ NWZ Wae N26 km Freiburg Heidelberg Hohenheim Karlsruhe Konstanz Mannheim Stuttgart Tübingen Ulm Freiburg Hop7by7Hop Doppelstern Heidelberg Hop7by7Hop Doppelstern Hohenheim Hop7by7Hop Doppelstern Karlsruhe Hop7by7Hop Doppelstern Konstanz Hop7by7Hop Doppelstern Mannheim Hop7by7Hop Doppelstern Stuttgart Hop7by7Hop Doppelstern Tübingen Hop7by7Hop Doppelstern Ulm Hop7by7Hop 77 Doppelstern 77 With less IP routers, round-trip time between two participants can jump from 3ms to 11ms in case of fibre cuts; should we worry? 13

14 Some open questions How many bandwidths will the participants need (between them)? Do we (still) need 10G waves, or do we go with coherent only? Mux all 10G applications into 100G/coherent? Should we build an bandwidth transportation network, e.g. with OTN or MPLS boxes, maybe directly in the optical network chassis? (We overcame ATM/SDH and other circuit switching ) Are 2 * 100G IP routers fine for us, or will the latency increase kill user applications? => Feedback anybody? Do we need optical protection or will our participants have two (redundant) bandwidths anyway? Direction-less everywhere? Or upgrade later? 14

15 Some open questions (cont.) Distribute ROADMs on two Locations on Campus? Spectrum sharing w/ participants ( customer )? We have that on some links today w/ static filters

16 It seams that 10G as wavelength is the cost-optimum Even if it brings +25% latency for compensation FlexGrid seams to necessary for 400G+, so we plan it today Ch. in 50 GHz grid Directed, colored for IP network Direction-less for bigger PoPs (as switchable bandwidths, for participants and additional backbone capacity) Color-less if we need to save wavelengths (?) Contention-less probably not necessary Less IP router and more latency between participants is fine 16

17 RIPE Atlas BelWü bought sponsored some RIPE Atlas Probes Idea: One Probe at each University Probes are managed by BelWü (Public or open) Measurement to targets in- and outside of BelWü Network performance like a users sees it 17
