CEF Networks workshop 2005 – [email protected] 3
FramingFraming• Investment vs. Maintenance• Inadequate corporate
solutions in the national market
• Geographical distribution• Insufficient growth when
compared with other NREN.• Availability of a fiber
provider
CEF Networks workshop 2005 – [email protected] 4
Goals – A new approach!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
CEF Networks workshop 2005 – [email protected] 5
Goals – GuidelinesGoals – 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
CEF Networks workshop 2005 – [email protected] 6
ProceduresProcedures
1. Passive fiber network
a. FO for the long distances
b. Local loops using fiber
2. Equipmenta. Transmission (Ethernet).
b. Routing (IP).
CEF Networks workshop 2005 – [email protected] 7
ProceduresProcedures
• International tender for long distance cable
• Winner - Refer Telecom (Railway Operator)
• Each local loop with a different approach
• Always trying to use existing pipes
CEF Networks workshop 2005 – [email protected] 8
Procedures - TransmissionProcedures - Transmission
• Limited to a public announcement
•Several proposals received
•Second round with best proposals
•Best-and-Final-Offers were asked
•ADVA was chosen
CEF Networks workshop 2005 – [email protected] 9
Procedures - RoutingProcedures - 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 – FeaturesLong Distance cable – Features
48 Optical fibers from witch:
• 24 x ITU-T G.652C (without water peak)
• 24 x ITU-T G.655
CEF Networks workshop 2005 – [email protected] 11
Long Distance Cable – Tests madeLong Distance Cable – Tests made
Tested:• Spectral attenuation• Chromatic dispersion• Polarization Modal
Dispersion• Reflectometry
attenuation• Insertion loss
CEF Networks workshop 2005 – [email protected] 12
Long Distance Cable – FeaturesLong 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
CEF Networks workshop 2005 – [email protected] 13
Cable - curiositiesCable - curiosities
• Mean attenuation of 0.21dB/Km
• Can connect 150Kms with with nothing-in-line

Access Local LoopsAccess Local Loops
Strategy:• use existing pipes• establish partnerships
with pipe owners• always have a ring
topology
Developing:– Aveiro, Braga, Coimbra, Lisbon
and Porto;

CEF Networks workshop 2005 – [email protected] 17
Access Local Loops - DifficultiesAccess Local Loops - Difficulties
• To coordinate all involved entities to meetings and surveys.
• Unexpected events on-site
CEF Networks workshop 2005 – [email protected] 18
Transmission SolutionTransmission 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
CEF Networks workshop 2005 – [email protected] 19
Routing EquipmentRouting Equipment
Cisco Equipment• 1 router in Lisbon• 1 router in Porto• 1 router backup/test
router• 10G Lan-Phy XENPAK
ports• 1G SFP ports
CEF Networks workshop 2005 – [email protected] 20
Routing – TopologyRouting – Topology• Dual star topology (Lisbon
and Porto)• Network “intelligence” on
the IP level• No more core/edge design
for the fiber connections (economical reasons)
• Fully redundant equipment• Lisbon-Porto backup link
from a commercial provider

Management and operation – TNMS COREManagement 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
CEF Networks workshop 2005 – [email protected] 22
Management and Operation – ApproachManagement 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
CEF Networks workshop 2005 – [email protected] 23
IP ServicesIP 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
CEF Networks workshop 2005 – [email protected] 24
Other Connections – Phase IIOther 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
