The Wild Wonders of Cisco IP
June 2013
With the advancement in the technological field, customers expect something extra from the service providers. Just traditional connectivity services aren’t enough; customers demand video, voice, VPNs, and IP-rich media content 
delivery with that! Therefore, to meet these demands while controlling costs and optimizing efficiency, the core network infrastructure needs to be converged to a Cisco IP Next-Generation Network (IP NGN).
The Cisco IP NGN possesses following characteristics:
- It simplifies architecture for core networks
- It reduces capital and operating expenses
- It also helps you deliver current services more efficiently
- Finally, it provides scalability and capacity for exponentially growing, bandwidth-intensive broadband services
You can realize the full benefit of the next-generation services by adopting a Cisco IP NGN framework with an intelligent, scalable Cisco IP/MPLS core routing solution.
Core Networks and their Carrier Routing System
The Cisco Carrier Routing System (CRS) series provides industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. Each model uses Cisco IOS XR Software, a unique self-healing, modular, distributed operating system. Models include the following:
- Cisco CRS-3, powered by Cisco QuantumFlow Array, offers from a single-chassis to a multichassis system up to 322 Tbps.
- Cisco CRS-1, built on the Cisco Silicon Packet Processor, offers from a single-chassis to a multishelf system up to 92 Tbps.
