The Cisco ASR 9000 Series Ethernet Line Card provides both dense hierarchical QoS and simultaneous support for both Layer 2 and Layer 3 services and features, enabling operators to qualify and stock a single line card that can be deployed in any combination of Layer 2 and Layer 3 service applications, thereby reducing capital expenditures (CapEx) and operating expenses (OpEx), as well as reducing the time required to develop and deploy new services. The Cisco ASR 9000 Series Ethernet Line Cards set a standard for service density, enabling operators to offer predicable, managed transport services while optimizing the use of network assets.
