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

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

Our vision: FlexSelect Architecture

What is FlexSelect?

Critical technologies: where we aim to lead

How does it translate into solutions

How are we going to deliver on it?


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

It is a network vision we’re committed to

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
