Founded on 20 years of innovation, the Cisco
® integrated services routers enable secure, wire-speed delivery of concurrent data, voice, and video services. They transparently integrate advanced technologies, adaptive services, and secure enterprise communications into a single, resilient system - greatly simplifying deployment and management. The routers lower network cost and complexity while providing exceptional investment protection. They feature embedded security processing, significant performance and memory enhancements, and new high-density interfaces that deliver the performance, availability, and reliability required for scaling mission-critical security, IP telephony, business video, network analysis, and Web applications in the most demanding enterprise environments. Built with greatly improved performance over the Cisco 1700, 2600XM, and 3700 Series routers, the Cisco integrated services routers (Figures 1-3) redefine best-in-class enterprise routing with their superior network agility and intelligence.

The Cisco integrated services routers introduce best-in-class routing, security, and voice technologies embedded into the router fabric, making it possible for enterprises to securely deliver concurrent, mission-critical services and applications at wire-speed performance. They extend network capabilities from the corporate headquarters to the branch offices for increased operational efficiencies and end-user productivity. Their advanced adaptability and modularity provide customers with a wide variety of network interfaces and services, including: VPN IP Security (IPsec), intrusion detection, IP communications, integrated switching, business video, URL filtering, Multiprotocol Label Switching (MPLS), application optimization, DSL, ATM access, and serial device aggregation. By consolidating the functions of multiple, separate services into a single, resilient platform that can be easily managed and deployed, Cisco Systems
® provides customers with the industry's leading routing platforms for growth and investment protection.
Secure Network Connectivity for Data, Voice, and Video
Security has become a fundamental building block of any network. Routers play an important role in any network defense strategy because security needs to be embedded throughout the network. The Cisco integrated services router portfolio features advanced, integrated end-to-end security for the delivery of converged services and applications. With the Cisco IOS
® Software Advanced Security feature set, the integrated services routers provide a robust array of common security features such as a Cisco IOS Firewall, intrusion prevention, IPsec VPN, advanced application inspection and control, Secure Shell (SSH) Protocol Version 2.0, and Simple Network Management Protocol Version 3 (SNMPv3) in one secure solution set. Additionally, with security functions integrated directly into the router, the Cisco integrated services routers can provide unique, intelligent security solutions that other security devices cannot, such as network admissions control (NAC) for antivirus defense; Voice and Video Enabled VPN (V
3PN) for quality-of-service (QoS) enforcement when combining voice, video, and VPN; and Dynamic Multipoint VPN (DMVPN) and Easy VPN for enabling more scalable and manageable VPN networks. In addition, Cisco offers a range of security-acceleration hardware such as intrusion-prevention network modules and advanced integration modules (AIM) for encryption, making the Cisco integrated services routers an ideal choice for branch offices seeking a robust and adaptable security solution.
With the unique architecture of the Cisco integrated services routers, customers can now securely deploy IP communications with traditional IP routing while leaving interface and module slots available for additional advanced services. With the optional integration of a wide array of services modules, the Cisco 1800, 2800, and 3800 Series Integrated Services Routers allow you to easily integrate the functions of standalone network appliances and components into the chassis themselves. Many of these modules, such as the Cisco network analysis module (NAM), Cisco voicemail module, Cisco intrusion detection module, and Cisco content engine module, have embedded processors and hard drives that allow them to run largely independently of the router while allowing management from a single management interface. This flexibility greatly expands the potential applications of the Cisco integrated services router platform beyond traditional routing while still maintaining the benefits of integration. These benefits include ease of management, lower capital expenditures (CapEx) and operating expenses (OpEx), and faster deployment.
The Cisco integrated services router portfolio may be positioned in the following manner (Figure 4) based on service and performance needs. Figure 5 provides an example deployment scenario.

KEY FEATURES AND BENEFITS FOR METRO ETHERNET CPE
The Cisco integrated services routers are ideal as Metro Ethernet customer premises equipment (CPE) for service provider deployments because of the wide range of voice, security, video, and advanced services that they support. These services make it possible for service providers to offer additional value to their enterprise customers, beyond simple Ethernet connectivity.
Key Cisco IOS Software features can be integrated directly on the Cisco 1800, 2800, and 3800 Series Integrated Services Routers. These features include: IP Multicast, Optimized Edge Routing (OER), intrusion detection system (IDS), intrusion prevention system (IPS), QoS, network-based application recognition (NBAR), IP service-level agreements (SLAs), Layer 2 and 3 MPLS, Layer 2 Tunneling Protocol Version 3 (L2TPv3), and NetFlow, as well as advanced services modules such as Cisco content engine modules, network analysis modules, Circuit Emulation over IP (CEoIP) modules, and Cisco Unity
® Express modules.
