What is Carrier Ethernet?• Carrier Ethernet is short for Carrier Grade Ethernet
• Carrier Ethernet is a set of extensions to Ethernet to enable SPs/Carriers to provide large scale Ethernet services and use Ethernet in their networks
• Carrier Ethernet has five attributes:
1- Standardized Services (E-Line & E-LAN)
2- Scalability
3- Reliability (rapidly detect & recover from failures)
4- Advanced Quality of Service (to offer SLAs)
5- Service Management (provisioning, diagnosing faults, and measuring performance)

Key Takeaways1. IP NGN is a converged packet network capable of providing L1, L2, &
L3 services with QoS and is access agnostic
2. Carrier Ethernet is a set of extensions to Ethernet to enable SPs to offer large scale Ethernet services and use Ethernet in their networks
3. ASR 1000 is Cisco’s strategic next-generation Midrange routerleveraging ground-breaking hardware capabilities of QFP
Horsepower of 40 Cisco 7200 on a single chip
State-of-the-art QoS and High-Availability
4. ASR 1000 is positioned for both Service Providerand Enterprise Architectures and is using IOS-XE technology
SP: Broadband Network Gateway, PE, Manage CPE,
Enterprise: WAN aggregation / optimization, Unified Communications
5. The Cisco ASR 9000 Series facilitates the evolution of Carrier Ethernet networks by setting a new foundational baseline for the edge.
6. The Cisco ASR 9000 Series uses the Cisco IOS XR Software Operating System, comprehensive system redundancy, and a full complement of network resiliency schemes.
