(Perceived) Problems Today
 Given current technology, Abilene is a viable shared
packet infrastructure. By 2006 when the current UCAID
Qwest contract expires will the available technology
drive us toward another architecture?
 Some discipline specific networks have enormous
bandwidth requirements
• High Energy Physics Community
• Square Kilometre Array Community
 Problems with packet infrastructures
• Variation in throughput, delay, jitter on shared packet
infrastructures.
• Will we have 40 Gb/s or 100 Gb/s in near future? Or more likely
n*10G waves.
• Increasing demand for deterministic paths.
• Demand for more dynamic requirements on bandwidth and
topology.

Looking to the Future

Examine potential new architectures

Advanced infrastructures
•
•

Packet-based network to support basic
functionality and application development.
A pool of optical switched waves that support
creation of dynamic networks for specific users or
disciplines.
Examining a Hybrid architecture of
dynamically provisioned Optical
lambdas and IP Packet Infrastructure

Deployment Issues with
Potential New Infrastructures







How do you define deterministic behavior?
How close to end nodes should optical waves be
switched? Where is the new edge?
How dynamic must optically switched paths be?
What duration do we expect of dynamic paths?
What is the interaction between the packet
infrastructure and the dynamically created paths or
the networks they form?
May require new measurement and troubleshooting
paradigm.
What are the interconnectivity requirements to end
systems, other research infrastructures (for
example, international or federal networks or
infrastructures)?

HOPI Resources
 MPLS over Abilene 10G backbone
 Internet2 10G Wave on the NLR
footprint
 MANLAN Experimental Facility
• Ethernet Switch – layer 2 switching
• ONS Switch – layer 1 switching
 The Regional Optical Networks –
RONs
• Working on interface definition

MANLAN Experimental Facility
MANLAN Proper is an Ethernet Exchange Point for R&E
Networks
Addition of Cisco 15454 to support projects such as the
Global Lambda Integration Facility (GLIF)
Current IEEAF/Tyco Circuit between Surfnet and Abilene
will be used for international experimentation
Connections
• CA*net
• Abilene
• Surfnet
Some near term tests: Lightpath consisting of a variety
of technologies crossing multiple administrative domains
There are many other experimental facilities – StarLight
(including Starlight-CERN OC192 link with Layer 2 and 3
services), NetherLight, etc.

HOPI Basic Service
Probably a 1 GE end-to-end path with
“reasonable” jitter and latency properties
Dynamically provisioned – understand degree
to which temporal setup is needed
Understand topological extent – for example,
host-to-host? Cluster-to-cluster?
Examine Backbone, RON, Campus hierarchy –
understand interface options
Network operations
Measurement activities

Current Status
Design team furiously working on
definitions for:
• Basic services model
• HOPI node design
• Connector interface
• Control plane requirements
• Management requirements
Target draft whitepaper for Spring (Apr)
Internet2 Members meeting
Planned testbed(s) implementation this
year.

Conclusions
Support
• Internet2 goal is to support the bandwidth needs of
the community as networking infrastructures evolve
in the future through shared, high-performance
packet networks and dedicated capabilities as
required.
