How Cisco CRS-X Delivers 10 Times the Capacity of CRS-1

Internet traffic growth has accelerated since the original CRS-1 routing system was introduced to the industry in 2004, as noted in the most recent Cisco Visual Networking Index (VNI) forecast. The latest VNI study predicts that global IP traffic wiil grow threefold from 2012 to 2017, reaching an annual run rate of 1.4 zettabytes by the end of 2017 -- that's up from 522.8 exabytes at the end of 2012.

Traffic growth and complexity is driving convergence at the core of the network. Multiservice, multipath and multi-access traffic requires a core solution such as the new Cisco CRS-X, which can support massive scale, continuous operation, cloud intelligence, carrier-grade network services, and IP and optical convergence.

“The Cisco CRS provides us with an intelligent core solution and the ability to scale up to 400 Gbps per slot, which will meet our service demands well into the future,” said Mike Haberman, vice president of network operations, Verizon Wireless.

The Cisco CRS-X can provide unmatched economical scale and lasting investment protection for more than 750 telecommunications service providers and organizations worldwide, including Verizon Wireless and SoftBank Mobile Corporation, that have deployed more than 10,000 CRS systems as the foundation of their network infrastructures.

The Cisco CRS-X, which will be available this year, is a 400 Gigabit per second (Gbps) per slot system that can be expanded to nearly 1 petabit per second in a multi-chassis deployment. The CRS-X provides 10 times the capacity of the original CRS-1, which was introduced in 2004 as a new class of core routing system designed to scale network capacity to accommodate the proliferation in video, data and mobile traffic, which has taken place over the last decade.

With today’s telecommunications service providers facing multiple challenges – such as limited scale, separate optical and Internet Protocol (IP) networks, and architectural constraints – the CRS-X expands the industry’s most scalable elastic core networking platform. With 400 Gbps per slot density, the CRS-X multichassis architecture delivers unsurpassed scale using a 400 Gbps line card with Cisco AnyPort technology.

The line card uses complementary metal oxide semiconductor (CMOS) photonic technology, called Cisco CPAK, to reduce power consumption, reduce the cost of sparing, and increase deployment flexibility. For example, each interface can be configured for either single port 100 Gigabit Ethernet, 2x40 GE, or 10 x10 GE and either short-, long-, or extended-reach optics by selecting a specific CPAK transceiver.

This flexibility simplifies network engineering and operations and helps ensure that service providers can meet the demand for 10 GE, 40 GE and 100 GE applications without replacing hardware.

Additionally, the CRS-X improves the simplicity and scale of IP and optical convergence. Service providers can now choose between deploying integrated optics or the new Cisco nV optical satellite. Both allow for a single IP and optical system that utilizes Cisco’s nLight technology for control plane automation. The nV optical satellite deployments operate as a single managed system with the Cisco CRS Family to reduce operational expense and deliver high-density 100 GE scaling.

The CRS-X delivers industry-leading capacity, cost-effective expansion and overall investment protection. By delivering a single system that has increased its capacity 10-fold in nearly 10 years, Cisco enables CRS customers to reduce their total cost of ownership by nearly 50 percent compared with the nearest competitive solution.

Over this period, the CRS has delivered customers 80 percent power savings, as well as a 76 percent savings in transport costs. The CRS-X system has been architected to help ensure that more than 10,000 existing CRS-1 and CRS-3 systems in operation can be easily upgraded with minimal traffic impact. Current CRS customers can migrate to CRS-X capability with simple in-service replacement cards. They may also expand by adding CRS-X to existing multi-chassis deployments.

“We are very pleased at the continued development of the Cisco CRS platform, which has served as the foundation of our advanced network infrastructure for many years. With the ability to scale to 400 gigabits per second and highly available architecture, the CRS continues to provide unparalleled investment protection and help ensure SoftBank Mobile’s ability to remain one of the leading broadband content and service providers in Japan,” said Junichi Miyakawa, executive vice president, board director & CTO, SoftBank Mobile Corporation.

Cisco CRS-X -- Ready for the Next-Generation Internet

The Cisco CRS is the industry’s most robust, scalable, widely deployed multi-chassis core router. Line cards supporting 4x100 GE and 400 Gbps per slot allows for unmatched economical scale of 64x100 GE ports in one chassis with a total multi-chassis system capacity of nearly 1 petabit per second.

The CRS-X 400 GE Line Card with Cisco AnyPort Technology uses Cisco’s CMOS photonic CPAK to reduce power consumption and increase 100 GE port densities by a factor of three compared to competitive solutions. CPAK technology also enables network operators to mix and match interface rates (10 GE, 40 GE, and 100 GE) and distances (SR, ER, and LR) within a single card.

The CRS-X uses the IOS-XR software, a unique self-healing and self-defending operating system designed for “always on” operation while scaling system capacity.

The Cisco CRS elastic core architecture delivers flexible scale, transport and services to help service providers minimize network complexity and maximize service monetization. Cisco nV Technology along with nLight Technology enables the optical transport equipment to be managed as a single entity, simplifying provisioning and network operations for dense 100 GE.
