Overview
The Cisco ASR 903 Router is a full-featured aggregation platform designed for the cost-effective delivery of converged mobile and business services. With redundancy, shallow depth, low power consumption and high service scale, this 3-rack-unit (3RU) router is optimized for small aggregation and remote point-of-presence (POP) applications. The Cisco ASR 903 Router provides a comprehensive and scalable feature set of Layer 2 VPN (L2VPN) and Layer 3 VPN (L3VPN) services in a compact package.¦The Cisco ASR 903 Router supports broadband aggregation for delivering "any-play" services (voice, video, data, and mobility). Designed to support thousands of subscribers, quality of service (QoS) on the Cisco ASR 903 Router is capable of scaling up to a large number of queues per device. This large number of queues, combined with a highly granular QoS algorithm (three-level hierarchical QoS), results in a greatly enhanced broadband user experience. This full-featured Layer 2 and Layer 3 switch router supports a variety of broadband applications including IPTV and video on demand (VoD), enhancing and extending the Cisco IP Next-Generation Network (IP NGN) architecture.¦The Cisco ASR 903 Router is built to meet service provider requirements for Carrier Ethernet aggregation. It is optimized for remote central office and smaller aggregation sites where a full-featured, small-footprint, fully redundant aggregation platform is needed. The Cisco ASR 903 Router offers service flexibility and delivers Layer 2, IP, and MPLS transport for advanced L2VPN, L3VPN, and multicast services.
