A single chip operates as a 10-Gbps full-duplex switch fabric providing 4x4 switch ports at 2.5-Gbps/OC-48c speed with standard CSIX-L1 interface. In a two chip configuration, the PRS 16G/C192 can operate as an 8x8 port, 2.5-Gbps/OC-48c switch fabric, thus offering an aggregate full-duplex throughput of 20 Gbps. As another two-chip configuration, one of the devices can be configured with a single 10-Gbps/OC-192c port with standard CSIX interface so as to provide the uplink aggregating the traffic of the four 2.5-Gbps/OC-48c ports of the other chip. The chip features configurable fixed-size packet switching and is capable of supporting either frame-based traffic (through segmentation and reassembly performed by the attached network processors) or cell-based traffic. In conjunction with switch designs based on PRS 64Gu or PRS Q-64G devices, adapter cards implementing the PRS C192 fabric interface can equip singlestage switching systems offering today up to 320 Gbps of 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 low-end boxes up to high-end, chassisbased solutions capable of switching up to 320 Gbps of aggregate full-duplex user traffic, while optimizing and protecting their line card design investments. This enables offerings that allow operators to deploy entry versions of their next-generation, chassis-based platforms, while they are introducing advanced IP-based services, for example, merging data and voice over Quality-of-Service (QoS)-aware networks, implementing virtual private networks (VPNs), or deploying security applications closer to the end users. Robust Features The following features provide design flexibility: • 10-Gbps (stand-alone chip) or 20-Gbps (back-to-back chips) aggregate user bandwidth • Four 2.5-Gbps/OC-48c NPU attachments or one 10G/OC-192c NPU attachment per chip Product Overview • Embedded standard CSIX-L1 interface to Network Processor or Traffic Manager • Switch/adapter cards with seamless connection between switch fabric chip and NPU(s) • Ingress Virtual Output Queuing (VOQ) with up to 1024 unicast queues and eight multicast queues • Quality-of-Service (QoS) support with four levels of traffic priority and four programmable ingress queue thresholds (ingress CSIX flow control per destination and priority) • Packet payload protection, with optional cyclic redundancy check insertion • Packet header parity generation and checking • Efficient multicast (replication at sending) Adapter CSIX GE 16 G bps 8 Links at 2.5 Gbps 8 Links at 2.5 Gbps GE Adapter CSIX OC-48 Network Processor OC-48 Network Processor OC-48 Network Processor OC-48 Network Processor 16 Gb ps 10G Network Processor PRS 16G/C192 PRS 64Gu, PRS Q-64G 1 0 Active Switch 1 0 Switch Control Switch Control OC-12 1 OC-12 4 16 ps Gb PRS 16G/C192 8 Links at 2.5 Gbps 8 Links at 2.5 Gbps 16 G bps 1 0 1 0 Protection Switch Fibre Channel Fibre Channel Switch Core (NxN) Switch Fabric 40-320 Gbps Switch Applications 2 Empowering Intelligent Networks Product Brief PB PRS 16G/C192 / v0.5 / 12-19-2003 PRS 16G/C192 Switch Fabric Redundancy Support for High Availability – PRS C192 Function To increase availability and meet service providers’ needs and high-demanding applications (24x7), switch fabrics are often designed with two redundant planes. If an element in one plane fails, the other plane can take over. The PRS C192 device supports this crucial capability, in conjunction with the PRS 64Gu or PRS Q-64G switch core devices. Each switch element has a built-in filtering mechanism for redundancy control. On the line adapter, the PRS C192 chip provides a redundant path with the switch planes, enabling traffic load sharing and switchover between the two switch planes, including maintenance switchover without packet loss. enable multicasting and maximize product resources utilization, the switch executes a scheme of store once and transmit multiple times (replication at sending). The multicast packet is placed in shared memory and the memory-location index is stored in the output queues corresponding to the target output ports and associated priorities. When used as a standalone switch, the PRS 16G/C192 inherits this leading multicast architecture, and so helps customers to efficiently take advantages of these multicast applications. Fabric Interface for Highly-Scalable Systems – PRS C192 Functions The PRS 16G/C192 switch fabric device is designed to alternately operate as a PRS C192 switch fabric interface chip. Located on each adapter card, it supports either a 10G/ OC-192c network processor or up to four 2.5G/OC-48c network processors. It performs the queuing manager function of a PRS-based switch that can scale from 4 to 32x10-Gbps/ OC-192c switch ports, or 16 to 128x2.5-Gbps/OC-48c switch ports, offering up to 320 Gbps of full-duplex aggregate user bandwidth. PRS 64Gu and PRS Q-64G switch core devices use 2.5-Gbps high-speed serial links for communication with adapter cards equipped with the PRS C192 fabric interface chip. The PRS 16G/C192 provides one 64- or 128-bit wide CSIX-L1 compliant interface or four 32-bit wide CSIX-L1 compliant interfaces to Network Processors or Traffic Managers. Highly Efficient Multicast – PRS 16G and PRS C192 Function Multicast with QoS is an increasingly valued capability in Internet and new service applications. The PRS 64Gu and PRS Q-64G switch core devices, in conjunction with the PRS 16G/C192 device provide a built-in efficient multicast function, easing the design of edge routers and other devices that provide these complex services.
