The Cisco ASR 1000 Series is a class of midrange routers that offers convergence of network services on highly scalable routing platforms. It delivers superior resiliency with intelligent services and modularity to meet the long-term needs of both enterprise and service provider applications.
The ASR 1000 Series is the first system to use the Cisco Flow Processor, a groundbreaking technology that offers superior multiprocessing, advanced memory management, customized quality of service (QoS), and silicon-based service delivery and programmability for emerging requirements.
The flexibility of this processor allows you to integrate network services such as packet encryption, packet inspection, application recognition, traffic differentiation, and subscriber management on a single routing platform, the Cisco ASR 1000 Series Router, without using external network appliances or service modules.
ASR 1000 Series Routers scale from Fast Ethernet to 10 Gigabit Ethernet (GE) and from DS-0 to OC 192/STM-64 with rich QoS features, allowing network operators to guarantee bandwidth to mission-critical applications and improve overall application user experiences.
