1 / 4 page ![]() Empowering Intelligent Optical Networks – Highlight s – Product Brief PRS 80G, PRS C48X, and PRS C192X Switch Fabric PB PRS / v0.6 / 2-10-2006 Empowering Intelligent Networks 1 Switch Fabric Solution with Carrier Class QoS Features for Applications up to 80 Gbps The AMCC PRS 80G is a switch device for systems in the range of 20-to-80 Gbps of aggregate user bandwidth. The PRS 80G is a cell switch, shared-memory device, which provides 80 Gbps of switching capacity. It uses .13-micron technology and embedded 3.2-Gbps SerDes to deliver 40 Gbps (one device) or 80 Gbps (two devices) of user bandwidth with an overspeed factor of two. Along with the AMCC PRS C48X and PRS C192X fabric interface devices, the PRS 80G addresses the critical QoS needs of a wide range of highly demanding applications that handle any mix of real-time and best effort traffic in the WAN multi-services, Wireless Infrastructure, Metro Ethernet, Enterprise, and TDM spaces. The PRS 80G provides low latency, carrier class QoS and full bandwidth multicast to efficiently handle real-time traffic (including TDM) and enable convergence of voice, video, and data traffic over a single network infrastructure. It fits the requirements of the new carrier services, while leveraging previous carrier investments by providing the capability to switch IP and TDM traffic concurrently on the same platform. The PRS 80G is an integral part of a complete system solution with AMCC's nP37xx integrated network processor and traffic manager products, framers, PHYs, PowerPC processors, and software. To facilitate the evaluation and prototyping of complete solutions, AMCC also offers an 80-Gbps reference switch board, as well as ATCA Switch boards, featuring the AMCC PRS 80G. RoHS Compliance to Enable Lead Free Designs The PRS 80G switch device and the PRS C48X and PRS C192X fabric interface devices are all available in two versions: the leaded version, for lead soldering process, and the version complying with the directive on the Restriction of the use of certain Hazardous Substances (RoHS) and enabling lead free soldering. PRS 80G Switch Device, PRS C48X and PRS C192X Fabric Interface Devices The PRS 80G device performs the switch core function, in configurations of one or two devices, depending on the switching capacity needs. The PRS C48X and PRS C192X devices perform the queuing manager function of the PRS 80G-based switches. An adapter card can be equipped with either a PRS C48X interfacing a 2.5-Gbps / OC-48 network processor or a PRS C192X interfacing a 10-Gbps / OC-192 network processor or up to four 2.5-Gbps / OC-48 network processors. Scalability and Multiple Port Speeds The PRS 80G switch, in conjunction with the PRS C48X and PRS C192X fabric interface devices, provides 40 Gbps (one device) or 80 Gbps (two devices) of full-duplex aggregate user bandwidth with an overspeed factor per-port of two to match wire-speed requirements for all possible traffic patterns, with all line protocols. The PRS 80G enables the design of switch fabrics with up to 32 ports for network processors that support OC-48c and multi-GE applications, or up to eight ports for network processors that support OC-192c, 10-Gbps, and multi-GE applications, or any intermediate mix of those ports. QoS Enforcement at Media Speed The PRS 80G enables full bandwidth utilization of the media connected to the payload boards, and still maintains high QoS performance: • End-to-end flow control mechanisms through the switch fabric, and programmable flow control thresholds (including multicast), enabling 100% utilization of the media bandwidth while maintaining low jitter • Natively multicast switching technology, enabling full bandwidth multicast while maintaining low switching delay QoS Enforcement at Media Speed, Real-Time Traffic Sup- port, Full Bandwidth Multicast • Non-blocking, shared-memory switch fabric chip set: PRS 80G Cell Switch device providing 80 Gbps of aggregate switching capacity, PRS C48X and PRS C192X fabric interface devices (queue managers) • Full chip set (PRS 80G, PRS C48X, and PRS C192X) available in RoHS compliant version for lead free designs • 40 Gbps or 80 Gbps of full-duplex aggregate user bandwidth with a per-port overspeed factor of two • QoS enforcement at media speed • Real-time traffic support (guaranteed precedence of time-sensitive traffic over other traffic types) • Multicast and broadcast full bandwidth support (100% line utilization) while preserving low switching delay • Deterministic low latency, typically a few microseconds for high priority traffic under worst case conditions (100% traffic load) • Traffic scheduling QoS options: strict priority scheduling, weighted round- robin, exhaustive highest priority first • End-to-end, in-band flow control mechanisms through the switch fabric • Redundant switch board operations: hot standby mode, load sharing mode, maintenance switchover (cell lossless) • AMCC SSC software for configuration, monitoring, and control of the switch board and AMCC SWICC software, a PC tool for local/ remote testing (traffic generation, digital eye, and so on) • Evaluation switch boards, including ATCA Switch boards, featuring the AMCC PRS 80G • System solution with AMCC's nP37xx, framers, PHYs, and PowerPC processors, and interoperability with third-party network processor devices |
