1 / 4 page  Empowering Intelligent Optical Networks – Highlight s – Product Brief PRS 5G and PRS 20G Switch Fabric PB PRS 5G-20G / v0.5 / 05-24-2004 Empowering Intelligent Networks 1 Cost Effective Switch Fabric Solu- tions for Smaller-Capacity Multi- Service Provisioning Platforms, Scalable to High-end Systems The AMCC PRS 5G and PRS 20G devices are members of the Packet Routing Switch (PRS) multi-purpose switch fabric family. They bring greater granularity and Internet class of service to smaller-capacity systems such as remote access devices, enterprise networking equipment, and low-end SAN systems. The PRS 5G and PRS 20G provide a flexible switching solution to satisfy the demand of applications offering 5-20 Gbps of full-duplex aggregate user bandwidth with an overspeed factor of two. An integral part of a complete system solution with AMCC network processors, traffic managers, framers, and software tools, the seamless upgrade path of the PRS 5G and PRS 20G to higher-capacity solutions, such as the PRS 80G, enables customers to develop efficient, smaller-capacity systems today, and easily evolve to larger systems in the future. The PRS 5G and PRS 20G chips are implemented with IBM 0.13 micron technology, use IBM 3.2-Gbps high-speed serial links, and introduce new system design options, such as PL3 interfaces for network processors and traffic managers (in addition to CSIX-L1). Dual Functionality, Switch and Fabric Interface, for Single Design of User Cards Across Entire Product Lines The PRS 5G and PRS 20G solutions are hardware and software compatible with the PRS 80G, PRS 64Gu, and PRS Q-64G high-end switch devices. The PRS 5G and PRS 20G devices can operate as either switching devices located on user cards of smaller-capacity systems, or switch fabric interface devices of user cards connected to the PRS central switch of a high-end system. Known as PRS C48X and PRS C192X when used as fabric interfaces, these devices address the scalability needs of product lines that offer users full-duplex bandwidth ranges between 5 Gbps and 320 Gbps. As switches for 5-20 Gbps platforms, the PRS 5G and PRS 20G are an ideal solution for cost-competitive, advanced services applications, such as medium-range routers with high-demand packet processing for network access/ edge aggregation; remote location thin appliances for firewall, SSL, VPN, security, intrusion detection; data center server appliances with deep packet processing; NAS/SAN equipment; and, more generally, service applications requiring a 10-Gbps uplink capability. As fabric interface devices for line cards, the PRS 5G and PRS 20G (PRS C48X and PRS C192X) enable cards designed for 5-20 Gbps platforms to be used in chassis-based platforms addressing the higher-capacity needs of applications in the Metro/WAN, wireless infrastructure, and enterprise (data center, NAS/SAN, High-end LAN). Cards implementing the PRS C48X or PRS C192X fabric interface can equip single- stage switching systems based on PRS 80G, PRS 64Gu, or PRS Q-64G switch devices, offering up to 320 Gbps of full-duplex user bandwidth. The integration of self-switching and fabric interface capabilities into a single device provides system vendors with an easy path to scale their platforms from smaller-capacity systems up to high-end, chassis-based solutions capable of switching up to 320 Gbps of full-duplex aggregate user traffic, while optimizing and protecting their line card design investments. With such OEM offerings, operators can deploy entry versions of next-generation, chassis-based platforms, while they are introducing Switching Solutions for 5-20 Gbps Advanced Services Applications, Optimized to Extend into the 20-320 Gbps Range • Multi-purpose devices operating as a switch fabric for thin appliances, or a fabric interface for chassis-based systems • PRS 5G Switch Fabric providing more than 2.5-Gbps of full-duplex user bandwidth for 5-20 Gbps meshed switch systems (no central switch fabric) • PRS 20G Switch Fabric providing more than 10-Gbps of full-duplex user bandwidth for 10 Gbps (single-card) or 20 Gbps (two- card) smaller-capacity systems • Embedded 3.2-Gbps SerDes, with 8b/10b coding, for an overspeed factor of two • CSIX-L1 and PL3 standard fabric interfaces for high-density cards with up to four multi-GE/OC-48c network processor or one 10-Gbps/OC-192c network processor • Complete multi-GE/OC-48c solution with the AMCC nP3700 Integrated Network Processor / Traffic Manager • Enabling standard-based AdvancedTCATM-compliant system designs • Product line designs in the 5-to- 320 Gbps range, within the same proven PRS Packet Routing Switch architecture and technology • Same cards for pizza boxes and chassis-based systems, for optimized investments in card design, manufacturing and supply • Highly-scalable solutions preserving customer investments in network processor cards |
