PRS Q-80G, PRS C48X, and PRS C192X Switch Fabric Product Brief PB PRS Q-80G / v0.61 / 2-16-2006 PRS Q-80G Switch Device, PRS C48X and PRS C192X Fabric Interface Devices The PRS Q-80G device performs the switch core function, in configurations of two, four, or eight devices, depending on the switching capacity needs. The PRS C48X and PRS C192X devices perform the queuing manager function of the PRS Q-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 Switch Fabric Solution with Carrier Class QoS Features for Applications up to 320 Gbps The AMCC PRS Q-80G is a switch device for systems up to 320 Gbps of aggregate user bandwidth. The PRS Q-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 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 Q-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 Q-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 80-Gbps and 320-Gbps reference switch boards. The PRS Q-80G switch, in conjunction with the PRS C48X and PRS C192X fabric interface devices, provides 80 Gbps (two devices), 160 Gbps (four devices), or 320 Gbps (eight 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 Q-80G enables the design of single-stage switch fabrics with up to 32 ports for network processors that support OC-192c, 10-Gbps, and multi-GE applications, or up to 128 ports for network processors that support OC-48c and multi-GE applications, or any intermediate mix of those ports. The PRS Q-80G also has built-in a 40-Gbps clear channel attachment capability, requiring a customer ASIC or FPGA to interface with a 40-Gbps protocol engine. RoHS Compliance to Enable Lead Free Designs The PRS C48X and PRS C192X fabric interface devices are 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. QoS Enforcement at Media Speed The PRS Q-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 Empowering Intelligent Optical Networks Empowering Intelligent Networks – Highlights – QoS Enforcement at Media Speed, Real-Time Traffic Support, Full Bandwidth Multicast • Non-blocking, shared-memory, single-stage switch fabric chip set: PRS Q-80G cell switch device providing 80 Gbps of aggregate switching capacity, PRS C48X and PRS C192X fabric interface devices (queue managers) • PRS C48X and PRS C192X available in RoHS compliant version for lead free designs • Up to 320 Gbps (eight devices) of full-duplex aggregate user bandwidth with a per-port overspeed factor of 2 • 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 roundrobin, 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, featuring two PRS Q-80G (80 Gbps) or eight PRS Q-80G (320 Gbps) • System solution with AMCC's nP37xx, framers, PHYs, and PowerPC processors, and interoperability with third-party network processor devices 1 PRS Q-80G, PRS C48X, and PRS C192X Product Brief Switch Fabric PB PRS Q-80G / v0.61 / 2-16-2006 Line Card NP / TM (nP37xx) 4 x OC-12 Product Overview Backplane CSIX / PL3 2x3.2 Gbps PRS C48X Protection Switch 5 Gbps Active Switch 2x3.2 Gbps Line Card CSIX GE 8x3.2 Gbps 10G / OC-192 NP / TM PRS C192X 20 Gbps 8x3.2 Gbps GE Line Card CSIX / PL3 4 x GE NP / TM (nP37xx) 4 x OC-12 NP / TM (nP37xx) 8x3.2 Gbps PRS C192X OC-48 Fibre Channel NP / TM (nP37xx) 20 Gbps PRS Q-80G (two, four, or eight per plane) 8x3.2 Gbps Serial Links at 3.2 Gbps (with 8b/10b coding) NP / TM PRS Q-80G Switch with PRS C48X and PRS C192X Fabric Interfaces Support of Real-Time Traffic (TDM) The PRS Q-80G addresses the technical challenges (latency, jitter) of merging real-time traffic with other traffic types over a single communication infrastructure: • Deterministic low latency, typically a few microseconds transit delay in worst case conditions (100% traffic load) for high priority traffic. • Guaranteed precedence of time-sensitive traffic (for example, TDM) over other traffic types, using fully preemptive traffic priority. Full Bandwidth Multicast The PRS Q-80G addresses the growing needs of audio and video distribution applications, thanks to its powerful multicast and broadcast mechanisms: cell replication at sending, with cells being scheduled at different times for different output ports. Multiple QoS Options The PRS Q-80G can be suited to the application specific QoS requirements thanks to multiple traffic scheduling options: • Strict traffic priority scheduling • Configurable credit table (weighted round-robin) to guarantee bandwidth to lower priority traffic 2 • Credit Table with fully preemptive highest traffic priority (exhaustive scheduling) Switch Board Redundancy for High Availability The PRS Q-80G can be designed to operate in redundant switch board configurations that address the high-availability requirements of five-nine applications. On the payload boards, the PRS C48X and PRS C192X Fabric Interface chips provide a redundant path with the switch boards. The PRS Q-80G supports three redundancy modes: hot standby mode (with automatic takeover of the traffic of the failing active board), traffic load sharing between the two switch boards (with automatic take over of the traffic of the failing board), and maintenance switchover between switch boards (without any service interruption and no cell loss). Control Software The control processor of the switch board runs the AMCC Secondary Switch Controller software (SSC), in charge of configuring, monitoring, and controlling the switch board operations. The SSC initializes the cell switch device, performs diagnostics, monitors device status, accumulates statistics, and in Empowering Intelligent Networks a redundant switch configuration, communicates with its peer to perform system recovery in case of component failure. In addition, the AMCC Switch Integrated Control Console (SWICC) tool, a PC software application, enables access to any addressable resources in the switch device to initiate or monitor any operational or test function (for example, traffic generation, digital eye, sense and operate of any bit, loop back, and so on). The SWICC can be used locally, on the customer premises, or for remote support. Backward Compatibility The PRS Q-80G, PRS C48X, and PRS C192X chipset offers backward compatibility enabling co-population of both existing and new line cards in the same chassis: the PRS Q-80G switch chip SerDes can operate at 2.5 Gbps per serial link (instead of 3.2 Gbps) to support line cards based on the previous PRS C192 fabric interface chip, while the PRS C48X and PRS C192X interface chips SerDes can operate at 2.5 Gbps per serial link (instead of 3.2 Gbps) to operate with switch cards based on the previous PRS 64Gu or PRS Q-64G switch chips.
