The Cisco® Carrier Routing System (CRS) provides outstanding economical scale, IP and optical network convergence, and a proven architecture. The Cisco CRS-X is powered by advanced portable address translation (PAT) advanced application-specific integrated circuits (ASICs), a chipset architecture based on multidimensional engineering, and Cisco IOS® XR Software, a unique self-healing, distributed operating system.
Networks are facing new challenges with the Internet of Everything. Trillions of things have become Internet ready and can start talking to each other, as well as to applications and people. The effects of machine-driven events change network dynamics and impose entirely new service requirements. Managing bandwidth is no longer enough. Networks must become more elastic and programmable, capable of adapting and evolving. As part of an evolving and programmable network, the Cisco CRS 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 supports up to 400-Gbps line rates, and its hardware is backward and forward compatible, helping to protect existing and future investments.
The Cisco CRS has two different 100 Gigabit Ethernet line cards, the Cisco CRS-3 1-Port 100 Gigabit Ethernet Interface Module (Figure 1) and the Cisco CRS-X 4-Port 100GE LAN/OTN Interface Module (Figure 2).
The Cisco CRS-X 4-Port 100GE LAN/OTN Interface Module 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)
• 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
• Energy monitor functionality that allows real-time power monitoring of each individual component, including PLIMs and line cards, fabric, performance route processor (PRP) through command line interface (CLI), beginning with IOS XR Release 5.1.1
The Cisco CRS-X 4-Port 100GE LAN/OTN Interface Module connects into an existing transport network and provides four ports, at 100 Gbps of data per port for 400 Gigabit Ethernet LAN physical layer (LAN-PHY) or optical transport network (OTN) Transport Unit Level 3 (OTU-4) transport. The interface module requires a 400-Gbps-capable modular services card, forwarding processor card or label switch processor card for operation. It is supported across Cisco CRS 8-slot, 16-slot, and multichassis systems, using either a Cisco CRS enhanced chassis or legacy chassis. The Interface module can operate in either a 400-Gbps or 200-Gbps mode. The 400-Gbps mode in a Cisco CRS enhanced chassis-based system allows the interface module to deliver full 400-Gbps line-rate throughput. However in a 200-Gbps mode, two of the four ports are in a shut-down state to conserve on power and thermals.
