Mindspeed Unveils Traffic Management and InternetWorking Processors

10/14/2003 - Mindspeed Technologies, Inc. (AMEX: MND), a leading supplier of semiconductor solutions for network infrastructure applications, announced a new family of four programmable traffic management and Layer 2 internetworking processors offering the broadest range of software-compatible network processing solutions in the industry. The new TSP3 family offers equipment manufacturers the ability to use one system design across multiple port speeds for a wide range of applications in enterprise, access and metropolitan networks, protecting their engineering investments and allowing them to quickly add new features with downloadable software upgrades.

The OC-3 (155 Mbps) M27480, 2xOC-3 (310 Mbps) M27481, OC-12 (622 Mbps) M27482, and OC-48 (2.5 Gbps) M27483 TSP3 devices and companion Ethernet-enabled PortMakerIII firmware applications are the third-generation of an architecture deployed and thoroughly tested in the field by service providers since 1999. Mindspeed has shipped more than 700,000 programmable network processor solutions to leading customers worldwide.

PortMakerIII applications will include Ethernet-enabled packet and cell traffic management, and Ethernet-to-asynchronous transfer mode (ATM) bridging. The first binary application package features AAL5 with ATM-to-multi protocol label switching (MPLS) interworking, which enables bandwidth-efficient transport of legacy ATM cell traffic over next-generation MPLS networks.

“Mindspeed’s new TSP3 family extends our long heritage in programmable traffic management solutions to Layer 2 internetworking with complete firmware compatibility across the product line,” said Tom Medrek, senior vice president and general manager of Mindspeed’s broadband internetworking systems business unit. “Our Ethernet-enabled PortMakerIII firmware offers the fine-grained traffic management required to enable ATM-quality service level agreements on converged packet-based networks.

“With the TSP3 family of devices and companion PortMakerIII firmware, our equipment customers can now design one line card that can be used interchangeably for a full range of applications, amortizing their engineering investment across equipment types,” Medrek added.

The TSP3 family enables the fine-grained quality of service (QoS) required to provision new services across a full range of packet and cell based networks such as ATM, next-generation synchronous optical networking (SONET), packet-over-SONET (POS), Ethernet, Ethernet over SONET (EoS), and frame relay designs.

“Collapsing multiple data networks into a single network offers service providers the promise of dramatically reduced operating and capital expenses,” said Allan Armstrong, program director at telecommunications industry analysis firm RHK. “By bridging legacy ATM networks with next-generation MPLS and Internet-protocol networks, Mindspeed’s new TSP3 family offers equipment manufacturers a flexible and cost-effective solution to merging multiple disparate networks with one system design.”

The new family of TSP3 devices is designed for a variety of broadband aggregation and multi-service switching equipment in enterprise, access and metropolitan-area networks, such as digital subscriber line access multiplexers (DSLAMs), next-generation digital loop carriers (DLCs), cable head ends, and fixed and mobile wireless gateways. Each device in the family is cost, performance, and feature optimized for target applications, and offers a wide range of data path interfaces including Ethernet, POS, UTOPIA, and PCI. To speed time-to-market, equipment manufacturers can use binary PortMakerIII firmware applications, or develop their own customized applications.

Technical Details
The OC-48 M27483 device architecture is based on two programmable OctaveTM microprocessor cores with multiple co-processing engines designed to manage packets and cells at up to 2.5 Gbps in single-service or multi-service applications. The 32-bit RISC Octave processors include specialized instructions for interworking and traffic management, providing efficient dispatching of parallel hardware operations while performing traffic stream processing functions. The integrated co-processing engines enable the M27483 to achieve optical wire-speed performance.

PortMakerIII firmware provides fine-grained traffic management capabilities including queuing, hierarchical shaping, scheduling, policing, congestion management, and switching up to 256K packet or cell streams. It manages Layer 2 protocol interworking by transporting Layer 2 frames over MPLS, IP-to-ATM (AAL2 and AAL5 segmentation and reassembly), Ethernet-to-ATM, Frame Relay-to-ATM, and IMA. The firmware is also available with a source-code license to allow product differentiation and multi-service operation with other PortMakerIII or custom applications.

Mindspeed also supplies a PCI-based evaluation board and extensive system development tools with both the binary and source-code versions of PortMakerIII. For customers using an off-the-shelf PortMakerIII application, the TSP3 board development kit (BDK) provides a complete reference design for system simulation, including a chip model, test bench, and diagnostic code for hardware design verifications. The software development kit (SDK) is a powerful development environment for customers modifying PortMakerIII source code or developing custom applications. It includes all of the contents of the BDK, as well as a code-generation tool chain and a hardware and software co-simulator.

Pricing and Availability
The M27483, M27482, M27481, and M27480 TSP3 devices are priced at $425, $250, $140, and $99, respectively, in quantities of 1,000. Samples of the M27483 and M27482 will be available in November 2003, and samples of the M27481 and M27480 will be available in the second quarter of calendar 2004.
