Part of the Cisco®ASR 9000 Series, the Cisco ASR 9903 Router (Figure 1) is a compact, high-performance router that delivers up to 3.6 Tbps of nonblocking, full-duplex capacity in a Three-Rack-Unit (3RU) form factor. Based on the same Cisco IOS®XR software image as the other routers in the Cisco ASR 9000 Series, the Cisco ASR 9903 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 9903: 400 Gigabit Ethernet, 200 Gigabit Ethernet, 100 Gigabit Ethernet, 40 Gigabit Ethernet, 25 Gigabit Ethernet and 10 Gigabit Ethernet, so it gives customers the flexibility to mix and match interface types on the same chassis and offers operators the readiness for mass-scale networking.
As a fully redundant, high-performance multi-purpose platform, the ASR 9903 router can be used in a wide range of customer's scenarios and use-cases: business PE, metro aggregation, cloud edge, Internet peering, Data Center Interconnect (DCI), and others. The compact size (depth is 600 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 9903 as a border router at the edge of the enterprise network and as a peering router for communication with Internet service providers.
