Part of the Cisco^® ASR 9000 Series , the Cisco ASR 9902 Router (Figure 1) is a compact, high-performance router that delivers up to 800 Gbps of nonblocking, full-duplex capacity in a Two-Rack-Unit (2RU) form factor. Based on the same Cisco IOS^® XR software image as the other routers in the Cisco ASR 9000 Series, the Cisco ASR 9902 Router delivers the features and services found on the ASR 9000 Series platforms, allowing customers to standardize on the same Cisco IOS XR operating system. Multiple port rates are supported by ASR 9902: 100/40 Gigabit Ethernet, 25 Gigabit Ethernet, and 10 Gigabit Ethernet, providing customers the flexibility to mix and match interface types on the same chassis and offering operators the readiness for mass-scale networking.

As a redundant, high-performance, multipurpose platform, the ASR 9902 Router can be used in a wide range of customer scenarios and use cases: business PE, metro aggregation, cloud edge, internet peering, Data Center Interconnect (DCI), Broadband Network Gateway (BNG), internet edge, and others. The compact size (depth is 19 in., 483 mm), front-to-back airflow, support of PTP Telecom profiles, and different port rates make this platform very efficient and flexible for using at the mobile edge in 4G/5G networks. Enterprise customers can deploy the ASR 9902 as WAN Core, WAN Edge, and WAN Aggregation, as well as a border router at the edge of the enterprise network and as a peering router for communication with internet service providers.
