Cisco ASR 1000 Series Aggregation Services Routers aggregate multiple WAN connections and network services including encryption and traffic management, and forward them across WAN connections at line speeds from 2.5 to 200 Gbps. The routers contain both hardware and software redundancy in an industry-leading high-availability design. The latest addition to the Cisco ASR 1000 Series is the Cisco ASR 1002-HX router. The new router supports up to 100 Gbps in a 2-rack-unit (2RU) form factor. It also has 8 built-in 10-Gigabit Ethernet (GE) ports and 8 1-GE ports, with the Ethernet port adapter (EPA) slot for expansion. The Cisco ASR 1000 Series supports Cisco IOS® XE Software, a modular operating system with modular packaging, feature velocity, and powerful resiliency. The Cisco ASR 1000 Series Embedded Services Processors (ESPs), which are based on Cisco Flow Processor™ technology, accelerate many advanced features such as crypto-based access security; Network Address Translation (NAT), thread defense with Cisco Zone-Based Firewall (ZBFW), deep packet inspection (DPI), Cisco Unified Border Element (CUBE), and a diverse set of data-center-interconnect (DCI) features. These services are implemented in Cisco IOS XE Software without the need for additional hardware support.
