What is optical networking?
Utilizing optical fiber to carry light as the lowest level data transport medium
Good source for basics of optical networking: http://www.sura.org/opcook

How is optical networking being discussed in research networking community?
Currently, two main threads of activity:
1) Obtaining and controlling fiber assets in order to build networks (at campus, metropolitan, regional, national levels)
2) Utilizing that control of optically-based transport layer to provision new types of services – “lambdas**” or “lightpaths”
….and sometimes simulating these without underlying control
**”a pipe where you can inspect packets as they enter and when they exit, but principally not when in transit” (C. deLaat et al.)
10
How have we provisioned networks in the past?
To date, primarily by buying services from telecommunications companies
• ATM service, SDH/SONET service, GigabitEthernet Services, wavelength services
Example: Abilene backbone network• Qwest provides 10Gbps wavelength between core nodes
• Abilene owns, controls routers
11
Providing network infrastructure by acquiring fiber assets
Unique window in time for fiber assets• Cause: fiber glut, bankruptcies and telcos in distress • Within a year, opportunity on national scale closes?• Hedge against a regression to ‘bad old days’ of monopolies
Technically, getting fiber means controlling the network down to layer 1 (0?)
• Would allow deployment of different wavelengths for differentiated networks (high perf advanced services, network research, more general EDU access)
• Path to doing optical switching when it makes sense
12
Unique optical requirements inHigher Education Community
10-Gbps: 10 Gigabit Ethernet preferred over OC-192c SONET
HPC could need 40-Gbps λ’s prior to the carriers
Integrated view of network management• Transport & IP engineering/operational approaches are not
intrinsically different• SNMP preferable for network polling
HEC can provide experimental environment for development of ‘rational’, customer focused optical switching
• Switching tightly integrated with optical transport• Capacity for IP backbone expansion and p2p λ’s
Metro/regional implementations lead (for technical and economic reasons)

Regional optical fanout
In the next generation architecture, regional & state based optical networking projects are critical
Three-level hierarchy remains vital• National backbone, GigaPoPs (ARNs), Campuses
Close collaboration with the Quilt GigaPoPs
• Regional Optical Networking project
17
Toward a National Optical Networking Facility
Research and education community investment in national-scale fiber assets
• Discussions among a number of partners in US ongoing
–“National Light Rail” – being led by members of Internet2 community – CENIC, the Pacific NorthWest Gigapop and other partners
–SURA – USAWaves project

Lambda* or Lightpath Networks
Current CA*net “customer-empowered networking” - prototypes a day when multiple wavelengths available to a site/desktop
Why?• Router limitations - cost• A few very bandwidth needy applications (e.g. between
radio astronomy sites) for which dedicated circuits make more (technical, economic) sense
• User control – configurability
An area needing more investigation, cost modeling, prototyping, etc.
21
Summary
There are many networks out there pursuing the dark fiber opportunity
• Scale is important• Regulatory factors • Take advantage of others’ experiences!
The “lightpath” model will be exciting area of investigation
• What are the right models? “Empowered customer” pays traditional circuit-switched network-type fees?
