Special Note Regarding Forward
Looking Statements
This presentation contains forward-looking statements that involve substantial risks and uncertainties,
including but not limited to, statements relating to goals, plans, objectives and future events. All
statements, other than statements of historical facts, included in this presentation regarding our strategy,
future operations, future financial position, future revenues, projected costs, prospects and plans and
objectives of management are forward-looking statements. The words “anticipates,” “believes,”
“estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would” and similar expressions are
intended to identify forward-looking statements, although not all forward-looking statements contain these
identifying words. Examples of such statements include statements relating to products and product
features on our roadmap, the timing and commercial availability of such products and features, the
performance of such products and product features, statements concerning expectations for our products
and product features [and projections of revenue or other financial terms. These statements are based on
the current estimates and assumptions of management of Force10 as of the date hereof and are subject
to risks, uncertainties, changes in circumstances, assumptions and other factors that may cause the
actual results to be materially different from those reflected in our forward looking statements. We may
not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements and
you should not place undue reliance on our forward-looking statements. In addition, our forward-looking
statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint
ventures or investments we may make. We do not assume any obligation to update any forward-looking
statements.
Any information contained in our product roadmap is intended to outline our general product direction and
it should not be relied on in making purchasing decisions. The information on the roadmap is (i) for
information purposes only, (ii) may not be incorporated into any contract and (iii) does not constitute a
commitment, promise or legal obligation to deliver any material, code, or functionality. The development,
release and timing of any features or functionality described for our products remains at our sole
discretion.

Role of Ethernet
in Optical Networks

Allocation of Optical Network Resources

Finer Control of Paths and Bandwidth

Integration between Optical & IP networks

Example: HOPI Project

You still need/want Ethernet:
– Integration with LANs, end sites
– Management / Subdivision of larger lambdas
– Higher layer services


HOPI - Hybrid Optical
Packet Infrastructure

Fundamental Questions:
How will the core Internet
architecture evolve?
What should the next
generation Internet2
network infrastructure be?


VLSR - The VLSR is a software suite which can be adapted to
switching elements of various technologies. These switching
elements can then act as a Label Switch Router (LSR) in
Generalized MultiProtocol Label Switching (GMPLS) context

Includes protocols and functions such as Open Shortest Path
First with Traffic Engineering extensions (OSPF-TE), Resource
ReServation Protocol with Traffic Engineering extensions
(RSVP-TE), Constrained Shortest Path First (CSPF) Path
Computation, and switching element resource control and
provisioning.

HOPI: Dynamic Control of VLANs (Virtual LANS)

Bandwidth Reservation for User Work (BRUW). BRUW is an
adaptation of the CANARIE User-controlled Lightpath (UCLP)
software to enable of MultiProtocol Label Switching (MPLS)
Label-Switched Paths (LSPs) dynamic provisioning across IP
routed infrastructures.
