Product Overview

The Cisco® Carrier Routing System (CRS) offers industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. The Cisco CRS is powered by an advanced chipset architecture based on multidimensional engineering and Cisco IOS® XR Software, which is a unique self-healing, distributed operating system.

Packet-based data communications is being replaced by video and multimedia transported over the IP next-generation network (NGN) in multiple directions. This changing traffic pattern poses new challenges for the architectural foundations of both public and private networks that serve businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS delivers highly reliable operations and scales easily from single-chassis form factors to a massive multichassis system. Its design provides industry-leading efficiency, with exceptionally low consumption of power, cooling, and rack-space, while delivering the bandwidth and intelligence required for multimedia services. The Cisco CRS-3 model builds on the CRS-1. It is backward-compatible and forward-compatible to help protect existing and future investments for decades to come.

The Cisco CRS Carrier Grade Services Engine PLUS (CGSE-PLUS) is an important element of the Cisco High-Scalability Solution. The Cisco CGSE-PLUS hardware (Figure 1) is an integrated multi-CPU service module offering carrier-class performance and scale. The Cisco CGSE-PLUS is designed for IP NGNs that can integrate routing with several intelligent applications. The Cisco CGSE-PLUS can run Cisco Open Network Environment Platform Kit (Cisco OnePK) applications, software-defined networking (SDN) applications, analytics applications, Cisco Carrier-Grade IPv6 Solution applications, and anti-distributed denial of service (DDoS) applications.

The Cisco CGSE-PLUS is a single-slot module supported on all Cisco CRS-1 and Cisco CRS-3 models. The Cisco CGSE-PLUS is second-generation hardware for the Cisco Carrier Grade Services Engine (CGSE) Physical Layer Interface Module (PLIM) that was released in November 2010.

Software-Defined Networking and Analytics

The Cisco CRS-1 and Cisco CRS-3 router models support SDN infrastructure through the Cisco OnePK services set, supported by Cisco IOS® XR Software. The OnePK service set in the Cisco CRS-1 and Cisco CRS-3 router platforms can run several applications in blade-hosting mode or external server-hosting mode. The Cisco CGSE-PLUS next-generation carrier-class services hardware is designed to host the Cisco OnePK applications on Cisco CRS-1 and CRS-3 routers. The Cisco OnePK applications can also be integrated with analytics applications and help ensure intelligent routing mechanisms, new monetizing opportunities, and optimized network infrastructure for service providers.

Carrier-Grade IPv6 Solution

The Cisco Carrier-Grade IPv6 Solution, running on one or more Cisco CGSE-PLUS modules inside a Cisco CRS, can scale to tens of millions of IP address translations, with tens of gigabits of performance to address IPv4 run-out and facilitate IPv6 transition. Several modules can be populated within a chassis for a high-performance solution that can be deployed in network locations that allow increased Cisco Carrier-Grade IPv6 coverage. The Cisco CGSE-PLUS supports a highly available architecture with line-rate accounting and logging of translation information. The platform’s Cisco IOS XR Software offers a flexible means to divert selected packets through the Cisco CGSE-PLUS, while allowing global IPv4 and IPv6 packets to flow through the Cisco CRS forwarding infrastructure as usual.

Powerful Performance

The Cisco CGSE-PLUS housed inside a Cisco CRS offers carrier-class performance for Cisco Carrier-Grade IPv6 services:

More than 1 million connection setups per second for stateful IPv4 and IPv6 Network Address Translation (NAT)

Real-time off-box logging of NAT states using Cisco NetFlow Version 9

Line-rate forwarding for IPv4 and IPv6

Powerful performance that helps ensure an outstanding end-user experience for all services

Exceptional Scalability

As an increasing number of subscribers and applications rely on the network, the Cisco CGSE-PLUS scales to support this growth:

Up to 80 million stateful NAT translations per Cisco CGSE-PLUS module

Support for tens to hundreds of thousands of private IPv4 subscribers accessing the public IPv4 Internet

Support for tens to hundreds of thousands of IPv6 subscribers accessing the IPv4 Internet

Support for multiple Cisco CGSE-PLUS modules in a chassis, allowing performance to be increased linearly

Integrated Services

The Cisco CGSE-PLUS module is designed for the proven Cisco CRS high-end routing platform. It is supported on all form factors of the Cisco CRS-1 and Cisco CRS-3, 8-slot, 16-slot, and multichassis versions. With these deployment options, service providers can scale the Cisco CGSE-PLUS to their needs. The Cisco CGSE-PLUS is also integrated with the routing intelligence of the Cisco CRS, providing the unmatched operational efficiencies of a single OS. Because the Cisco CRS platform supports secure domain routing (SDR), service providers can integrate the Cisco CGSE-PLUS on a virtualized network infrastructure.


The following services are available on the Cisco CGSE-PLUS: Full IPv4 and IPv6 routing and forwarding on the Cisco CRS platform

Service provider-class stateful IPv4 Network Address Translation (NAT44) to address IPv4 run-out, based on IETF NAT behaviors described in RFCs 4787, 5382, and 5508

IPv6 Rapid Deployment Border Relay (6rd BR, described in RFC 5969)

Stateful and stateless IPv4 and IPv6 translation, based on IETF BEHAVE specifications

The Cisco CGSE-PLUS interface module on the Cisco CRS offers service providers a near-term solution to address IPv4 run-out and preserve their present mode of operation. It also provides one or more low-risk, cost-effective means to activate IPv6 tunneling and translation functions.
