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
E-Mail, SPAM detection
Network services (DNS, NTP, ...)

A short history
1987 BelWü was founded
First bridged network, later routed, partially IP over X.25
1989
All (BaWü) Universities are connected to BelWü
1994
Full mesh of all Universities with 2-34 Mbit/s
1998
Upgrade to Cisco 7500 and 155 Mbit/s ATM links
2001 Upgrade to Gbit/s-Network with Cisco 12410/GSR
SRP/DPT rings with 2.4 Gbit/s and 622 Mbit/s
2006
First 10Gbit/s link
2010
Upgrade to 100Gbit/s-ready-Network with Cisco ASR 9000,
own (passive) DWDM and (multiple) 10Gbit/s Ethernet links
2013
June: First 100Gbit/s link

BelWü optical and IP Network 2014
On fibers:
Static DWDM filter w/ 4-8 Channels and EDFA
Colored 10GigE DWDM transceiver
(Menara w/ FEC) in IP Router (ASR 9000)
Parallel: Ekinops/Opelian 10x10G to 100G Mux
Hop-to-hop, no long-run wavelengths
Today:
Fiber on main paths
Redundancy via rented 10GigE bandwidths
Target Q2/2016:
Continous & redundant fiber-only network

BelWü Services
Services:
IPv4, IPv6
Firewalling (up to 1G, smaller Universities)
Layer 2 VPNs/Bandwidths
1/10G Ethernet over MPLS (via IP/MPLS Router)
10/100G
Wavelengths (via DWDM; only few Hops)
10G Bandwidths (10x10G to 100G Mux, BelWü-NeIF)
With very different requirements ...
And of course a lot of Network related Servies ...

2014-2016+
Tendering for:
1. Fibers (-only Network)
2. Optical Network
3. 100G IP Router (100G access for bigger Universities)
Potential Timeline:

Campus - ROADM static

Campus - ROADM dynamic
15
Statements / Questions
Buying 100G equipment starting end of 2015 seems to be a good time.
Smaller chips, more 100G port per line-card (optical and IP)
Fixed Questions:
Grid-less ROADMs - to have super channels in the future
(Dispersion Compensation must be aware of that!)
16
Statements / Questions (cont.)
Open:
Distribute ROADMs on two Locations on Campus ?
Dispersion compensation for long-haul 10G waves ?
Or only short-haul 10G waves (e.g., hop-to-hop) ?
(Re-use “old” 10G DWDM transceiver ?)
Big chassis or small chassis for each degree ?
Spectrum sharing w/ participants (“customer”) ?
We have that on some links today w/ static filters
(Swapping wavelengths with $ISP ?)
Less IP router, more latency between participants - problem ?
Is there wavelength rewriting ?
17
Challenge
Catch up your own team
We are new to ROADMs - that took us a while ...
No fancy/graphical NMS system
With optical equipment this would be mandatory ?
Necessary for tiering NOC structur (?)
We overcame ATM/SDH and other circuit switching
Now we are back to wavelength/OTN/Layer 2-VPN/etc. switching... ?
