Chapter 1: Routing 1-39

Routing

QoS), Multiprotocol Label Switching (MPLS), and Hierarchical Virtual Private LAN Services (H-VPLS). The

ASIC provides line-rate performance and offers advanced services including access control list (ACL) and

H-QoS without affecting performance. The Carrier Ethernet ASIC incorporates innovative traffic-

management capabilities while providing intelligent packet switching and routing operations.

• Service richness—With the Cisco ASR 903 Router, customers will be able to deliver services ranging from

basic TDM, ATM, and Ethernet services to advanced feature-rich and secure MPLS services, including

Pseudo Wire Emulation (PWE), Carrier Ethernet (CE), Multiprotocol Label Switching Transport Profile (MPLS-

TP), MPLS Layer 2 VPNs (MPLS L2VPNs), and MPLS Layer 3 VPNs. The service offering is enhanced with

rich operations, administration, and management (OAM) functions including: IEEE 802.1ag Connectivity Fault

Management (CFM), IP service-level agreement (IP SLA), Y.1731 Fault Management and Performance

Management, Bidirectional Forwarding Detection (BFD), and MPLS OAM.
