Effective limit of new equipment

5 years

Bandwidth Demand

slide5

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.
slide6

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)
slide7

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
slide8

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
slide9

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!!

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

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

slide15

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

slide16

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

slide18

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
slide20

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

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

  • Define the edge ports of the IP network
  • Define the external Routing Service(policy)
  • In case there are preferences on internal transport services, QoS: the internal Routing Service metric
  • Your IP address pool (guided by your ISP)

example deployment
Example deployment
  • Two organizations:
  • NREN A: Physical Network Administrator. In this very simple example it operates a network with one physical router.
  • i2CAT: Virtual Network Administrator. In this very simple example it will request two logical routers to NREN A.
  • MANTICORE Software deployment
  • NREN A Server:
  • User Workspace WS
  • Ethernet Resource WS
  • IP Network WS
  • Router WS
  • i2cat Server:
  • (optional)‏
  • User Workspace WS
  • Ethernet Resource WS
  • IP Network WS

slide41

When NREN A first launches the GUI client, it must create a new physical network and add all the routers they want to manage to it.

44

16

slide43

Create logical interfaces

  • Create logical routers
  • Assign i/fs to routers
  • Create tunnel between the logical routers

46

18

slide46

OSPF configuration

BGP configuration

  • i2cat logical admin creates a new IP Network and adds the resources of the resource list to it.
  • Now he can configure the IP parameters of the interfaces, configure IGPs, configure the peering, ...
