For the ST200 Service Edge Router

Download Data Sheet

The ECI ST200 Service Edge Router incorporates a unique, distributed architecture that enables service providers
to deliver a complete range of services with the performance, scalability and flexibility to meet current and future requirements.
Key to this distributed architecture is the ST200 Network Processor Blade (NPB), a high-performance packet processing and forwarding card.

Wire-speed Performance
Designed to meet the performance requirements of the multi-service edge, ST200 Network Processor Blades (NPBs) perform all packet processing, Layer 2/3 forwarding, IP filtering, Quality of Service (QoS) functions, accounting and link management at
wire speed — with no compromise in performance.

The ST200 always performs at wire speed, even with all services and features enabled and thousands of customers connected.This is in sharp contrast to centralized router architectures where performance degrades as customers are added and services are
turned up.

Unmatched Flexibility
The NPB provides revolutionary flexibility by allowing service providers to accommodate new services as they evolve. Regardless of how services, encapsulations or interfaces shift over time, the NPB provides investment protection via tunable hardware and software. Services can even be enabled on a per customer interface basis.This level of flexibility is the key to future-proofing and scaling networks as new value-added services emerge.

For maximum flexibility, the NPB is compatible with all ST200 Physical Interface (PHY) cards, significantly reducing sparing costs.

Robust Scalability
The ST200 architecture is highly distributed for increased scalability. Processing power increases with each NPB (up to eight) added to the system, resulting in performance that is an order of magnitude greater than other routers. This distributed architecture enables service providers to purchase only the bandwidth they need today, scaling as traffic demands increase. Forwarding table capacity also increases as NPBs are added to the system, enabling large numbers of customers to be supported
per ST200. In contrast, other routers use a centralized forwarding table, which limits the number of customer-facing interfaces.

For improved routing protocol performance and scalability, the NPBs handle all per-customer link management, Layer 2 processing and performance monitoring functions, enabling the
ST200 Route Control Processor to focus on the task of scalable routing.

Sophisticated QoS
The NPB provides sophisticated QoS functions that are configurable per logical interface.Wire-speed packet classification and filtering provide differentiated services based on IP source/destination application. Standard and custom policing schemes enable the creation of burstable services with guaranteed bandwidth. Flexible queuing strategies meet service level agreements (SLAs) while providing multiple distinct service classes for each customer.And, traffic shapers ensure that customers receive only their purchased bandwidth — nothing more, nothing less. These advanced capabilities allow service
providers to precisely match existing SLAs while enabling new
value-added IP-based services in a single platform.

About NPB Cards
NPB cards work in concert with Physical Interface (PHY) cards, terminating or forwarding a wide range of Layer 2 and IP-based services as they are received into the ST200. NPBs provide wire-speed performance, unmatched flexibility, robust scalability and sophisticated QoS.
