Technologies Gigabit Ethernet, Fiber-Optics, Rambus, PowerPC,
a start-up in the Switched Gigabit Ethernet Space, was developing
a family of switch products just before the ratification of the IEEE
Gigabit Standard. It had two distinct issues which prompted it to
evaluate external resources to assist in product development:
need to introduce multiple products in a family simultaneously
technology, requiring substantial knowledge and experience to mitigate
Cirque Networks desired technology partners with substantial manufacturing
knowledge so that manufacturing scheduling and yield targets could be
Networks, a venture-funded start-up, found itself competing in the initial
race to introduce switched Gigabit Ethernet to the marketplace. It wanted
to introduce a family of high-performance Gigabit switches that would
be appropriate for small to medium sized, fast growing, companies. This
target market imposed a number of design constraints due to target cost
and time-to-market requirements.
Adding to the potential complexity was the fact that Cirque Networks
had retained an Industrial Design (ID) firm in Atlanta, GA to assist
in the artistic aspect of the packaging. The ID firm presented compelling
visual designs, which addressed the needs of the target market well
but were made with no forethought as to the mechanical integration
issues with the electronic sub-system.
When Dynazign was contacted to assist in the effort, a very aggressive
schedule was in place to deliver functional prototypes of the first
two products in the family for an industry trade show in less than six
weeks. Additionally, after the trade show was complete, the schedule
called for the initiation of four more switches, as well as support
for the first two products as they went into production.
In summary, Cirque Networks needed a technology partner that could provide
advanced technical knowledge, project management skills and leadership
in the transfer to the manufacturing process.
outset, it was clear that success could only occur by initiating a triage
process, so that the full scope could be determined and priorities assigned.
This was accomplished by meeting with engineering management of both
Cirque Networks and its Industrial Design partner. Because of the interrogatory,
Dynazign was able to establish both the critical path, as well as necessary
supporting items that were not directly on the critical path, but were
required for success.
Because of the triage process, a crash program was initiated to make
the first two products ready for the trade show. The major critical
path items to accomplish this task were:
Integration with Packaging (Industrial Design)
Board Layout (Specifically split planes, Ball Grid Array (BGA) routing
/ shielding issues and impedance matching)
result of the crash program was 100% unqualified success Dynazign
Style. Cirque Networks was able to introduce and demonstrate both products
at Networld+InterOp according to plan. This was by no means the end
of the project, because Cirque Networks still needed to begin design
on four more switches and move the first two into volume production.
Using the same project management techniques, Dynazign again decomposed
the challenges into prioritized tasks. Once this was done, we facilitated
task assignment and extracted commitments from outside vendors.
In the end, Dynazign delivered on every commitment and every schedule
milestone. Eventually this resulted in six Fast and Gigabit Switch designs,
and one very happy client.
of techniques were applied in this project over a period of nine months.
Some of the notable technologies and innovations included:
modeling and analysis of trace impedances
mechanical modeling using ProE and AutoCAD
Mhz. Rambus Channel Design and Simulation
Speed Parallel Bus Design
Micro-strip custom module interface
Split Plane Construction for Noise Isolation and Power Distribution
Stack Implementations (TCP/IP, SNMP, ICMP, VLAN etc)
The combination of these advanced technology skills and innovative analysis
provided Cirque Networks with a feature rich and competitive family
of network switches.
