Deployment scenarios

• City rings
• Short-ish distances (0.1-10km), many drops
• Rings start/end at one POP
• Traffic resilience at Ethernet level (Layer 2)
• (Rapid) Spanning Tree Protocol
• Regional daisy chains
• Longer distance (10-100km)
• Chain starts at one POP, ends at another
• Traffic resilience at IP level (Layer 3)
• 2 eBGP peerings (primary and backup) with
  customers
• Bandwidth gt 1GE needed deploy CWDM, DWDM

Optical Ethernet topologies ring/chain

Optical Ethernet equipment

• Cisco Catalyst 4912G
• Rack mounted, 12 GBIC ports
• Typically, 3 ports in use
• 1x SX GBIC, facing LAN (to customer router)
• 2x LX or ZX GBIC, facing WAN (to SURFnet
  backbone)

CWDM upgrade scenario
11
DWDM

• Long distance links, multiple 1G / 10G needs
• Amplifiers every 80-100km
• Deployed on dark fibers Amsterdam Dwingeloo
• 190km of G.655 fiber
• Optical amplifier halfway, 22dB, in carrier
  repeater site
• DWDM Cisco 15252, metro DWDM kit

12
Deployment experience so far

• Ethernet / CWDM buildout operation very
  straightforward
• Plug play. User friendly.
• CWDM is just another type of GBIC
• DWDM more complicated
• Build, upgrade complex. Cascaded EDFA tuning
  not easy
• DWDM operations monitor analogue optical
  parameters
• NREN NOC knows IP/Ethernet. Needs to learn real
  optics now.

SURFnet6 overview

• Realization of a next generation hybrid network
  with seamless end-to-end communication
• Based on customer-owned managed dark fiber
• Native IPv4, IPv6 and Lambda Services over a
  single transmission infrastructure managed via a
  single control plane
• Multi-domain networking
• Ethernet services as part of the WANs
• Intelligence of networks and the associated
  responsibilities at the edges
• Paving the way to a ubiquitous and scalable
  Services Grid
