Today’s telecommunications service providers facing multiple challenges – such as limited scale, separate optical and Internet Protocol (IP) networks, and architectural constraints – the CRS expands the industry’s most scalable elastic core networking platform.

Carrier Routing System or CRS is a modular and distributed core router that enables service providers to deliver data, voice, and video services over a scalable IP Next-Generation Network (NGN) infrastructure. In a network topology, these routers are generally positioned in the core or edge of a service provider network.

In this Video we will be covering following topics:

  • What is CRS?
  • CRS-1 Router Chassis Options
  • Cisco CRS-1 System Configurations
  • CRS-1 System Closure view
  • CRS-1 16 Slot hardware overview
  • CRS-1 8 Slot hardware overview
  • CRS-1 4 Slot hardware overview
  • CRS-1 Forwarding and Chassis Common Elements
  • Switch Fabric
  • CRS-1 packet Flow
