TRANSCRIPT
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 history1987 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
2014 100Gbit/s at each University PoPs3

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)

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
6
(Big) Campus - today
Nicht eingezeichnet:Dispersionskompensation

BelWü-NeIF10G bandwidths
Paralell to IP Network
10G bandwidths with 10x10G to 100G Mux & 10G matrix
Not redundant

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 ...

BelWü (Fiber) Footprint 2016 ???
100G IP Ports for clients at yellow dots
100G IP Routers at few central locations only
100G waves in the core network (red lines)
12
2014-2016+Tendering for:
1. Fibers (-only Network)
2. Optical Network
3. 100G IP Router (100G access for bigger Universities)
Potential Timeline:
13
Campus - ROADM static
14
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... ?
