Integrated LAN Switching

The Cisco 3900 Integrated Services Routers support the new, enhanced Cisco SM-X Layer 2/3 EtherSwitch® Service Modules, which greatly expand router capabilities by integrating industry-leading Layer 2 or Layer 3 switching with feature sets identical to those found in the Cisco Catalyst® 3560-X Series Switches performing local line-rate switching and routing.
The new, enhanced Cisco SM-X Layer 2/3 EtherSwitch Service Modules take advantage of the increased power capabilities on the Cisco 3900 Series platforms. They supports PoE+, MACsec, and Cisco TrustSec® technology. Additionally, the modules enable Cisco energy and power initiatives: Cisco EnergyWise, Cisco ePoE and per-port PoE power monitoring, and integrated redundant power system (RPS)-enabled PoE boost. These technologies allow you to meet increased endpoint power requirements without increasing the total power consumption of the branch office.

Application Services

As organizations continue to centralize and consolidate their branch-office IT infrastructure in an effort to reduce cost and complexity, they are challenged to provide adequate user experience, ensure continuous service availability, and deliver business-relevant applications when and where they are needed. To address these challenges, the Cisco 3900 Series enables you to host Cisco, third-party, and custom applications on a portfolio of high-performance Cisco SRE modules that transparently integrate into the router. The modules have their own processors, hard disks, network interfaces, and memory that operate independently of the host router resources, helping to ensure maximum concurrent routing and application performance while reducing physical space requirements, lowering power consumption, and consolidating management.

Application Acceleration

The Cisco 3900 Series transparently combines industry-leading security, Cisco IOS Software-based traffic control, and visibility with Cisco application-acceleration solutions. Cisco IOS Software features such as Network-Based Application Recognition (NBAR), IP service-level agreement (IP SLA), and NetFlow provide visibility and monitoring of traffic patterns and application performance while Cisco IOS Software features such as QoS, access control lists (ACLs), and Performance Routing intelligently control the traffic to maximize the quality of the user experience and employee productivity. You can further enhance user experience by adding a Cisco Wide Area Application Services (WAAS) Network Module to securely provide more advanced WAN optimization techniques such as TCP optimization, caching, compression, and application acceleration. Cisco Integrated Services Routers combined with Cisco WAAS Network Modules provide optimal performance for applications delivered from a central data center to branch-office users. The solution allows you to consolidate costly server, storage, and backup infrastructure into data centers while maintaining LAN-like service levels for remote users.
