Hardware New IP Network uses Cisco CRS-1 s • Scalability – 40 Gbit/s interfaces Hardware New IP Network uses Cisco CRS-1 s • Scalability – 40 Gbit/s interfaces currently installed – Upgrade to 100 Gbit/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 – 10 Gbit/s New Features • Top Class solution which allows for future growth – 10 Gbit/s connections available now – Scale to 100 Gbit/s peer, multi-10 Gbit/s per client when required in future • Support for critical new features – High Availability online IOS-XR updates etc – IPv 6 multicast – 4 byte ASN – Secure Domain Routing (Virtual Routing)

Collapsed backbone • Best Current Practice: • Model now being followed by many NRENs 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 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 – Current Client Status • All Clients transitioned onto New Network • Ethernet Connectivity – allows clients burst up to 10 Gbit/s per interface – Provision for Future 10 Gbit/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!!

ROADMS HEAnets network? Why in Why are ROADMS needed ? • More Capacity is ROADMS HEAnets network? Why in Why are ROADMS needed ? • More Capacity is needed in Fibre Core Network now – By 2009/2010, UCD, DCU and TCD will all require 10 Gbit/s IP links – The aggregate bandwidth (considering p 2 p 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 10 Gbit/s links.

What is a ROADM? Reconfigurable Optical Add Drop multiplexer • Software configurable DWDM Multiplexer What is a ROADM? Reconfigurable Optical Add Drop multiplexer • Software configurable DWDM Multiplexer • Flexibility to add/drop/continue wavelengths • Ability to provide 10 Gbit/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. • 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 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 Dynamic connections 2010 availability with ROADMS Contact HEAnet NOC for further Details
