CEF Networks workshop 2005 – lorga@fccn.pt

framing
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

CEF Networks workshop 2005 – lorga@fccn.pt

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 – lorga@fccn.pt

goals guidelines
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

CEF Networks workshop 2005 – lorga@fccn.pt

procedures
Procedures
  • Passive fiber network
    • FO for the long distances
    • Local loops using fiber
  • Equipment
    • Transmission (Ethernet).
    • Routing (IP).

CEF Networks workshop 2005 – lorga@fccn.pt

procedures7
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

CEF Networks workshop 2005 – lorga@fccn.pt

procedures transmission
Procedures - 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 – lorga@fccn.pt

procedures routing
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

CEF Networks workshop 2005 – lorga@fccn.pt

long distance cable features
Long 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 – lorga@fccn.pt

long distance cable tests made
Long Distance Cable – Tests made

Tested:

  • Spectral attenuation
  • Chromatic dispersion
  • Polarization Modal Dispersion
  • Reflectometry attenuation
  • Insertion loss

CEF Networks workshop 2005 – lorga@fccn.pt

long distance cable features12
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

CEF Networks workshop 2005 – lorga@fccn.pt

cable curiosities
Cable - curiosities
  • Mean attenuation of 0.21dB/Km
  • Can connect 150Kms with with nothing-in-line

CEF Networks workshop 2005 – lorga@fccn.pt

access local loops
Access 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 – lorga@fccn.pt

access local loops aveiro
Access Local Loops - Aveiro

CEF Networks workshop 2005 – lorga@fccn.pt

access local loops lisboa
Access Local Loops – Lisboa

CEF Networks workshop 2005 – lorga@fccn.pt

access local loops difficulties
Access Local Loops - Difficulties
  • To coordinate all involved entities to meetings and surveys.
  • Unexpected events on-site

CEF Networks workshop 2005 – lorga@fccn.pt

transmission solution
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

CEF Networks workshop 2005 – lorga@fccn.pt

routing equipment
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

CEF Networks workshop 2005 – lorga@fccn.pt

routing topology

FCCN -Lisboa

FCCN-Porto

U. Coimbra / IPC

U. Aveiro

U. Minho

U. Lisboa

U. Tec. Lisboa

U. Nova Lisboa

Routing – 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

CEF Networks workshop 2005 – lorga@fccn.pt

management and operation tnms core
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

CEF Networks workshop 2005 – lorga@fccn.pt

management and operation approach
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

CEF Networks workshop 2005 – lorga@fccn.pt

ip services
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

CEF Networks workshop 2005 – lorga@fccn.pt

other connections phase ii
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
