Cisco 2900 Series Wireless and Mobility Services Wireless LAN/WAN The Cisco Integrated Services Routers supporting the Cisco Unified Wireless Architecture enable deployment of secure, manageable wireless LANs (WLANs) optimized for remote sites and branch offices, including fast secure mobility, survivable authentication, and simplified management. The Cisco Wireless LAN Controller Module on the Cisco 2900 Series allows small and medium-sized businesses (SMBs) and enterprise branch offices to cost-effectively deploy and manage secure WLANs. Cisco Wireless LAN Controllers work in conjunction with Cisco lightweight access points and the Cisco Wireless Control System (WCS) to provide system-wide WLAN functions, managing up to 6, 12, and 25 access points. Wireless WAN Cisco third-generation (3G) wireless WAN (WWAN) modules combine traditional enterprise router functions, such as remote management, advanced IP services such as voice over IP (VoIP), and security, with mobility capabilities of 3G WAN access. Using high-speed 3G wireless networks, routers can replace or complement existing landline infrastructure, such as dialup, Frame Relay, and ISDN. Cisco 3G solutions support 3G standards High-Speed Packet Access (HSPA) and Evolution Data Only/Evolution Data Optimized (EVDO) providing you with a true multipath WAN backup and the ability to rapidly deploy primary WAN connectivity.

Integrated LAN Switching The Cisco 2900 Integrated Services Routers (Cisco 2911 through Cisco 2951) support the new Cisco Enhanced 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 2960 and Catalyst 3650-E Series Switches performing local line-rate switching and routing. The new Cisco Enhanced EtherSwitch Service Modules take advantage of the increased power capabilities on the Cisco 2900 ISRs. Additionally, the Cisco Enhanced EtherSwitch modules enable the newest Cisco power initiatives, Cisco EnergyWise, Cisco Enhanced Power over Ethernet (ePoE), per-port PoE power monitoring, and RPS- enabled PoE boost. These technologies allow you to meet increased endpoint power requirements without increasing the total power consumption of the branch. 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 an excellent user experience, ensure continuous service availability, and deliver business-relevant applications when and where they are needed. To address these challenges, the Cisco 2900 Series provides the capability to host Cisco, third-party, and custom applications on a portfolio of high-performance Cisco Services Ready Engine (SRE) modules that transparently integrate into the router. The modules have their own processors, storage, 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 2900 Series seamlessly combines industry leading security, IOS based traffic control and visibility, with Cisco application acceleration solutions. Cisco IOS Software features such as NBAR, IP SLA, and NetFlow provide visibility and monitoring of traffic patterns and application performance while IOS features such as QoS, ACLs, and PfR intelligently control the traffic to maximize the quality of the user experience and employee productivity. The user experience can be further enhanced through the addition of a Cisco WAAS Network Module which can be used 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. 98 Cisco 2900 Series Wireless and Mobility Services continued Cisco Unified Computing System Express The Cisco Services Ready Engine solution is available in a Service Module and Internal Service Module (ISM) form-factor. The Service Module hardware offers up to a seven times performance improvement over the previous-generation Network Modules and provides a multi-core x86-64 processor. The SRE modules also support up to 1 terabyte of storage, RAID configurations, hardwareassisted virtualization and cryptography options. The Cisco SRE module enables on-demand provisioning of branch-office applications on the Cisco 2900 Series platforms so that you can deploy the right application, at the right time, in the right place. The hardware and software decoupling provided by the service-ready deployment model enables applications to be provisioned on the module at the time of its installation or remotely anytime thereafter. Supported solutions include Cisco Wide Area Application Services (WAAS), Cisco Unity Express, Cisco Application Extension Platform (AXP), Cisco Wireless LAN Controller (WLC), Cisco Video Surveillance, and other applications under development. The Service Ready Engine enables organizations of various sizes to future-proof their network by allowing them to quickly deploy new branch-office applications without deploying new hardware, reducing the cost of rolling out branch-office services. Managing Your Integrated Services Routers Network management applications are instrumental in lowering operating expenses (OpEx) while improving network availability by simplifying and automating many of the day-to-day tasks associated with managing an end-to-end network. Day-one device support provides immediate manageability support for the Integrated Services Router, enabling quick and easy deployment, monitoring, and troubleshooting from Cisco and third-party applications. Organizations rely on Cisco, third-party, and in-house developed network management applications to achieve their OpEx and productivity goals. Underpinning those applications are the embedded management features available in every Integrated Services Router. The new Integrated Services Routers continue a tradition of broad and deep manageability features such as IP service-level agreement (IP SLA), Cisco IOS Embedded Event Manager (EEM), and NetFlow which allow you to know the status of your network at all times. These features, along with Simple Network Management Protocol (SNMP) and syslog, enable your organization's management applications. 99
