CEF Networks workshop 2005 – lorga@fccn.pt
Framing
• Investment vs. Maintenance
• Inadequate corporate
solutions in the national
market
• Geographical distribution
• Insufficient growth when
compared with other NREN.
• Availability of a fiber provider
3
CEF Networks workshop 2005 – lorga@fccn.pt
Goals – A new approach!
• New infrastructure for the long run
• Gain more autonomy towards the
market
• Solve the “long lasting”capacity
limitations
• Be side by side with the most
advanced NREN
• Provide the means for high
bandwidth projects and services
4
CEF Networks workshop 2005 – lorga@fccn.pt
Goals – Guidelines
• New and simpler network design
• Ethernet based
– 10GE backbone
– Nx1GE access
• Same Control panel for IPv4/IPv6
• Redundancy in the backbone
through a provider
• New backbone for the whole
network
• Stage I – connecting Lisbon-Braga
5
CEF Networks workshop 2005 – lorga@fccn.pt
Procedures
1. Passive fiber network
a. FO for the long distances
b. Local loops using fiber
2. Equipment
a. Transmission (Ethernet).
b. Routing (IP).

CEF Networks workshop 2005 – lorga@fccn.pt
Procedures
• International tender for long
distance cable
• Winner - Refer Telecom
(Railway Operator)
• Each local loop with a
different approach
• Always trying to use existing
pipes
7
CEF Networks workshop 2005 – lorga@fccn.pt
Procedures - Transmission
• Limited to a public
announcement
• Several proposals
received
• Second round with best
proposals
• Best-and-Final-Offers were
asked
• ADVA was chosen
8
CEF Networks workshop 2005 – lorga@fccn.pt
Procedures - Routing
• Similar to the
transmission, without a
public announcement
• Several proposals
received
• Second round with best
proposals
• Best-and-Final-Offers
were asked
• Cisco was chosen

Long Distance cable – Features
48 Optical fibers from
witch:
• 24 x ITU-T G.652C
(without water peak)
• 24 x ITU-T G.655

Long Distance Cable – Tests made
Tested:
• Spectral attenuation
• Chromatic dispersion
• Polarization Modal
Dispersion
• Reflectometry attenuation
• Insertion loss
11
CEF Networks workshop 2005 – lorga@fccn.pt
Long Distance Cable – Features
• Dialectical central strength
member: fiberglass
• 5 loose tubes – 4 with 12
fibers each
• Water resistant
• Anti-rodent armouring
• Complies with crushing,
tension and temperatures
specifications
12
CEF Networks workshop 2005 – lorga@fccn.pt
Cable - curiosities
• Mean attenuation of
0.21dB/Km
• Can connect 150Kms with
with nothing-in-line
13
CEF Networks workshop 2005 – lorga@fccn.pt
Access Local Loops
Strategy:
• use existing pipes
• establish partnerships with
pipe owners
• always have a ring topology
Developing:
– Aveiro, Braga, Coimbra, Lisbon
and Porto;
14
CEF Networks workshop 2005 – lorga@fccn.pt
Access Local Loops - Aveiro
15
CEF Networks workshop 2005 – lorga@fccn.pt
Access Local Loops – Lisboa
16
CEF Networks workshop 2005 – lorga@fccn.pt
Access Local Loops - Difficulties
• To coordinate all
involved entities to
meetings and surveys.
• Unexpected events on-
site
17
CEF Networks workshop 2005 – lorga@fccn.pt
Transmission Solution
• Minimalist approach -
several distinct point-to-
point solutions;
• Intelligence and services
on the IP level
• The transmission is just the
10GE and 2GE access links
• Solution -> ADVA Optical
18
CEF Networks workshop 2005 – lorga@fccn.pt
Routing Equipment
Cisco Equipment
• 1 router in Lisbon
• 1 router in Porto
• 1 router backup/test router
• 10G Lan-Phy XENPAK ports
• 1G SFP ports
19
CEF Networks workshop 2005 – lorga@fccn.pt
Routing – Topology
• Dual star topology (Lisbon and
Porto)
U. Minho
• Network “intelligence” on the
IP level
U. Aveiro FCCN-
Porto
U. Coimbra
/ IPC • No more core/edge design for
the fiber connections
(economical reasons)
FCCN - U. Nova • Fully redundant equipment
U. Lisboa
• Lisbon-Porto backup link from
Lisboa Lisboa
U. Tec. a commercial provider
Lisboa

Management and operation – TNMS CORE
TNMS-CORE from Siemens:
• Integrated management
• Centralized monitoring and
configuration
• End-to-end connection
management
• Alarm and error monitoring
• Performance management
21
CEF Networks workshop 2005 – lorga@fccn.pt
Management and Operation – Approach
• Monitoring using another
fiber pair with passive
transceivers
• Ethernet switches directly
connected to the
transmission equipment
• Non usage of dedicated
cards/equipment
22
CEF Networks workshop 2005 – lorga@fccn.pt
IP Services
• Migration of current IP
services to the new
backbone:
– IPv4/IPv6 Unicast and
Multicast
– R&D e .COM Classes of
Service
• Offer new and richer classes
of service
• Study the possibility of
having VPNs
23
CEF Networks workshop 2005 – lorga@fccn.pt
Other Connections – Phase II
• Consulting market again
in 2005.
• New advanced solutions
of renting fiber, lambdas,
GE and FE
• Redundancy solution for
the backbone, through a
national ring
