Mainframe vs. PC Battle Ciena is pointing to the future of Optical Transport
Traditional design approach : Mainframe:
- faster, bigger telecom-specific ASICs- Proprietary, highly integrated optics- Functionality tailored to a specific protocol/task
Ciena is building the first Programmable Optical Layer- Fully programmable blades that can be
reprogrammed to any need and application- Pluggable optics from a wide variety of vendors
(just like 3rd-part PCI cards)- Taking advantage of datacom FPGA + NPU’s

Telecom HW: FPGAs are taking over ASICs
SONET/SDH EthernetStorage
Digital VideoOTU

Gigabit Ethernet
FPGA Technology rapidly approaching the capabilities of ASICs
Allows to build hardware with Software defined functionality
Ciena’s FlexSelect technology is an example where Transponder, muxponder, ring add-drop, sub-wavelength grooming, and cross connect can be SW-configured
Less planning, fewer cards, configurations, and spares

What is FlexSelect?
It is not a marketing campaign
FlexSelect is an architecture that consists of a set of strategic tools integrated across the network that allow customers to transition to Ethernet/IP at their own pace

5. Packet interworkingBuilding a leadership position with our implementation
Ciena believes three identifiable functions comprise a full Ethernet solution
Ethernet Demarcation: The point at which Ethernet services or Ethernet transported services enter the provider network.
Ethernet Transport: The deterministic aggregation and forwarding of packet flows from application clients to servers, or from demarcation devices to service creation platforms.
Ethernet Service Switching: Service creation and service aware platforms, with enhanced per-service visibility and fully featured bridging functions.

Ethernet Traffic Management for SLAs Traffic Policing & Shaping
Instead of scheduling mechanisms, Bandwidth Profiles can also be applied to output queues – referred to as shaping
Eliminates starvation of bandwidth to WFQ traffic by Strict Priority traffic
Bandwidth Profiles on Ethernet and VCG ports, plus congestion control, together provide effective Ethernet traffic management in a network that uses EoS
