The Cisco®Carrier Routing System (CRS) provides outstanding economical scale IP and optical network convergence and a proven architecture. Cisco CRS modular service cards (MSCs) are 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.

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.
