Updates for BelWü 2016+
Long-run contract (3*5 y) with bandwidth and fibre provider ends in 2016
BelWü 2016+
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, 2016

Will tender for fibres (~2.000km)
Now: Defining criteria for tender for fibre (starting next month)
Legal things are getting more complicated :/
Campus Optical - today
Nicht eingezeichnet:Dispersionskompensation
ROADM directed/colored
ROADM direction-less/color-less
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
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 ?

With less IP routers, round-trip time between two participants can jump from 3ms to 11ms in case of fibre cuts; should we worry ?
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
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 …
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
80-88-96 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

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
