Today

Effective limit of old equipment

Effective limit of new equipment

5 years

Bandwidth Demand


Hardware

New IP Network uses Cisco CRS-1s

  • Scalability

    • 40 Gbit/s interfaces currently installed

    • Upgrade to 100Gbit/s interfaces in future

      => 1.5+ Terabits per second total

  • Supports current and future services

  • New operating system platform: IOS-XR designed for future Protocol and Services.


New Features

  • Top Class solution which allows for future growth

    • 10Gbit/s connections available now

    • Scale to 100Gbit/s peer, multi-10Gbit/s per client when required in future

  • Support for critical new features

    • High Availability online IOS-XR updates etc

    • IPv6 multicast

    • 4 byte ASN

    • Secure Domain Routing (Virtual Routing)


Collapsed backbone

  • Best Current Practice:

  • Model now being followed by many NRENs SURFNET , SUNET

    Concentrate, then duplicate

    • Concentrating =>

      • Less hardware,

      • Less to go wrong,

      • Easier to scale

    • Duplicating =>

      • Resilience

      • Network Consistency

    • Two routers

      • One in Citywest, one in Kilcarbery Park


Project Implementation

  • Late Nov - Acceptance tests

  • End Nov - HEAnet services transferred

  • Dec - First clients and peers

  • Jan-Feb - Next 10 clients

  • Feb-April - Next 20 Clients

  • May-Aug - Remaining 25 clients

    • Technology conversions / connection upgrades


Current Client Status

  • All Clients transitioned onto New Network

  • Ethernet Connectivity

    • allows clients burst up to 10Gbit/s per interface

    • Provision for Future 10Gbit/s client connections

  • BGP Peerings

    • client gets connectivity via NBE to both routers

      • Primary/backup connections

      • Resilience now a function of the underlying NBE

      • BGP changes in previous years paid off –

        Thanks!!


Current Peering Status

2007

2008

Tiscali

Telia


Multi-pop backbone

  • Overlaid on National Backbone

  • Dark fibre network provides Ethernet point-to-point capability

    • Brings networkto the client

    • Reduces cost

    • Increases flexibility

    • Adds resilience

  • now expanded by NBE Project


Heanets roadm network
HEAnets ROADM Network

HEAnets ROADM Network

Uses Adva FSP 3000 ROADMs Rev 7 CfT 2008

Fully Compatible with CWDM Network


Why are roadms needed

Why ROADMS in HEAnets network?

Why are ROADMS needed ?

  • More Capacity is needed in Fibre Core Network now

    • By 2009/2010, UCD, DCU and TCD will all require 10Gbit/s IP links

    • The aggregate bandwidth (considering p2p and IP links) inside the Dublin Metro Ring will be soon be larger then 10 Gbit/s.

    • Other Regions are following the same pattern

  • Other Projects expected to aggravate this Bandwidth problem

    • e-INIS Project

    • HPC: ICHEC & other grid clusters or supercomputers

  • Researchers may also require Point to Point Connections to CERN’s Large Hadron Collider and other projects. Normally 10Gbit/s links.


What is a roadm
What is a ROADM?

Reconfigurable Optical Add Drop multiplexer

  • Software configurable DWDM Multiplexer

  • Flexibility to add/drop/continue wavelengths

  • Ability to provide 10Gbit/s circuits “on demand”

  • Uses Combination of new technologies.

    • Tunable lasers

    • GMPLS control plane

  • Fast Evolving Technology

    Performance and cost reductions continuously

    => implement only in network where required


ROADM advantages

  • Network Layout planning is flexible and can be modified quickly.

  • Allows Backbone capacity expansion without need for additional Fibres

  • ROADM allows for remote configuration and reconfiguration.

    • ROADMs allow for automatic power balancing

  • In a DWDM network , making changes is more complex requires more pre design , provision and power balancing .

    DWDM Networks => Static Designs

    ROADMs give more flexibility


HEAnets wavelength service ?

  • Point to point circuit connectivity

  • Ethernet Frame format

  • Offers

    • No contention

    • Protection or No Protection

  • Dublin Metro Ring

    Dynamic connections Immediately availability with ROADMs

  • National/International

    Static Immediately with DWDM

    Dynamicconnections 2010 availabilitywith ROADMS

DWDM

Commissioned Oct 2008


Future Network Integration

  • Development of an API/Web service for access to the GMPLS interface for

    E-INIS , AutoBAHN projects and others

  • Implement as a GMPLS Network

    This will allow

    • Wavelength based network discovery

    • Wavelength based end-to-end circuit/path provisioning

    • Optical Restoration


Autobahn bandwidth on demand

AutoBAHNBandwidth on Demand


AutoBAHN

  • a Research activity for engineering, automating and streamlining the inter-domain setup of guaranteed capacity (Gbps) end-to-end paths

    • Bandwidth on Demand

      … a Joint Research Activity of the GN2 project

    • GN2 is an European Commission-funded project, with all the European Research and Education networks (NRENs) as partners


Sc 08 demo
SC 08 Demo

4 Sites simulating Radio Telescopes, 3 in Europe and 1 in the US

Data transferred on 4 by 1 Gb BoD links to Software Correlator in Amsterdam


Point to Point path issues

  • Multiple administrative domains

  • Multiple data plane technologies

  • Security


Autobahn s approach
AutoBAHN’s approach

  • NREN Distributed control and provisioning

  • Business-layer related interactions include AA, policies, advance reservations etc.

  • Privacy and control of intra-domain resources must be safeguarded

    => Definition of a Full Architecture

    • Inter-Domain Manager (IDM) Provisioning

    • Domain Manager (DM) Technology Specific

    • Interfaces Local Provisioning

    • CARNET,DANTE,GARR,FCCN

  • 2 Working Technology Proxies for full automated Provisioning

    • HEAnet MPLS/ Ethernet, DANTE SDH

  • 7 Demos in 2008

    • 4 Connectivity based

    • 3 Application based High Definition Video, SCARI/e

  • GN3 Implementation across NRENS 2009 – 2013

  • Working on standardisation efforts
