The Cisco® CRS-X Carrier Routing System provides outstanding economical scale, IP and optical network convergence, and a proven architecture that’s delivered 10 times the capacity over 10 years. The Cisco CRS-X Modular Service Card (MSC) is powered by advanced application-specific integrated circuits (ASICs), a chipset architecture based on multidimensional engineering, and Cisco IOS® XR Software, a unique distributed operating system.
Packet-based data communications are being replaced by video and rich media transported on the IP Next-Generation Internet and his new traffic strains the architectural foundations of both public and private networks serving businesses and consumers. As part of the medianet, a media-aware Cisco Next Generation Internet, the Cisco CRS-X delivers highly reliable operations and scales easily from single-chassis form factors to a massive multichassis system. Its design offers industry-leading efficiency in power consumption, cooling, and rack-space resources, while providing intelligent service-rich bandwidth capacity. The Cisco CRS-X, which supports 400-Gbps line rates, is backward and forward compatible with the Cisco CRS-1 and the Cisco CRS-3, helping to protect existing and future investments.
The Cisco CRS-X Modular Services Card (Figure 1) offers the following advanced features and benefits:
● 400-Gbps line-rate throughput per slot, increasing the Cisco CRS capacity to 12.8 Tbps in a single chassis
● Advanced forwarding ASICs to support 100-Gbps single-flow traffic processing with optimized power consumption
● Superior investment protection that maintains the existing Cisco CRS architecture, making it compatible with existing Cisco CRS-1 and Cisco CRS-3 line cards and physical layer interface modules (PLIMs)
● Transparent and In-service migration from an existing Cisco CRS-1 or Cisco CRS-3
● Space, cost, and power savings with 100-Gbps Cisco CPAK™ optics
● Flexibility through Cisco AnyPort Technology, which introduces 100-Gbps to 40-Gbps and 40-Gbps to 10‑Gbps breakout options
The Cisco CRS-X MSC provides a distributed forwarding-engine capability for the Cisco CRS Family. Optimized for high-speed edge applications, it provides massive VLAN scale and wire-rate hierarchical quality of service (QoS). It is responsible for data-plane processing tasks, for all the network traffic that flows through it. The card performs all baseline packet routing operations, including Layer 3 forwarding, QoS classification, policing and shaping, security access control lists (ACLs), VPNs, load balancing, and Cisco NetFlow. Important performance features include hardware-assisted policing and multicast packet replication that reduces jitter and latency.
This Cisco CRS-X line card is supported across the Cisco CRS 8-slot, 16-slot, back-to-back, and multichassis form factors and is compatible with both Cisco CRS enhanced and traditional chassis-based systems. The line card has two 200-Gbps forwarding ASICs and can operate in either 200-Gbps or 400-Gbps mode. While operating in 400-Gbps mode in a CRS enhanced chassis-based system, both ASICs are functional, and the line card delivers full 400-Gbps line-rate throughput. In 200-Gbps mode, one of the two forwarding ASICs shuts down to conserve power.
The Cisco CRS-X MSC offers many advantages:
● Transparent operation with previous-generation Cisco CRS-1 and CRS-3 line cards on the same chassis with Cisco CRS-X fabric
● Increased capacity, by scaling the Cisco CRS per-slot forwarding capacity 10 times, from 40 Gbps to 400 Gbps
● Flexible pairing with a variety of interface modules, providing deployment flexibility
● Single-flow Layer 3 traffic processing at 100 Gbps in each direction
● Enhanced onboard multicore CPU for accelerated software processing
● Optimized for high-speed edge applications with enhanced QoS
● Outstanding interface and VLAN scalability
● Wire-rate hierarchical QoS
● Layer 3 forwarding engine with industry-leading, wire-rate performance
● Additional services, such as class-of-service (CoS) processing, multicast, traffic engineering, and statistics gathering, performed at line rate
● Support for up to 64,000 queues and 12,000 interfaces in hardware
● Built-in hardware acceleration for critical network control traffic
● Accurate hardware-assisted time-stamping support for service-level agreement (SLA) monitoring
● Support for several forwarding protocols, including IPv4, IPv6, and Multiprotocol Label Switching (MPLS)
● Enhanced performance with hardware-based prefix lookup for IPv4, IPv6, and MPLS
● Industry-leading environmental efficiency with a low power consumption and weight
