Product Overview
Cisco
® Wide Area Application Services (WAAS) Software on Cisco Integrated Services Routers Generation 2 (ISR G2) provides router-integrated, on-demand WAN optimization and application acceleration for branch offices. Cisco WAAS has been designed since inception to provide the highest degree of integration with Cisco routing solutions. Cisco WAAS offers the option to integrate physically with first- and second-generation Cisco ISRs. The Cisco Services Ready Engine (SRE) Modules on the ISR G2 platform, which decouple software services from the underlying hardware, can deliver WAN optimization as an on-demand service as required for business objectives and IT budget. This approach allows organizations to make better use of existing investments while offering business agility (Figure 1).
Figure 1. Cisco SRE Module
Cisco WAAS is a comprehensive WAN optimization and application acceleration solution that is a crucial component of Cisco Borderless Networks and data center and virtualization architectures. It accelerates applications and data over the WAN, optimizes bandwidth, empowers cloud computing, and provides local hosting of branch IT services, all with industry-leading network integration.
Cisco WAAS helps achieve IT objectives including:
• Enhance branch-office and mobile user productivity by optimizing application performance
• Reduce costs by enabling centralization of IT resources and reducing bandwidth expenses
• Increase IT agility with faster delivery of branch-office services with the services-ready module
• Lower branch-office operating expenses through integration of functions on a router platform
The Cisco WAAS advantages include:
• Application-specific acceleration validated by application vendors
• Network integration that preserves existing network services and results in ease of operations
• Cost-effective solution with router-integrated modules for branch offices
Cisco WAAS Product Portfolio
Cisco WAAS platforms are available as appliances and as integrated modules for Cisco ISR and ISR G2 platforms.
• Appliance-based product lines include Cisco Wide Area Application Engine (WAE) and Wide Area Virtualization Engine (WAVE) products.
• Integrated modules are available as Cisco SRE Modules for Cisco ISR G2 routers and Cisco WAAS Network Modules (NMEs) for Cisco ISR and ISR G2 routers. NME adaptors are required to use network modules on the Cisco ISR G2 platforms.
The Cisco WAAS product line is designed to scale from small to very large enterprise-wide deployments. Cisco WAAS Modules for Cisco ISRs typically are deployed as edge devices at branch-office locations. Cisco WAE and WAVE appliances are deployed symmetrically as edge devices at branch-office locations and as core devices at the data center, as shown in Figure 2.

Features and Benefits
Cisco WAAS on Cisco SRE Modules delivers the features and benefits listed in Table 1.
Table 1. Features and Benefits
Feature
Benefit
On-demand provisioning
• Customer can provision solutions, such as Cisco WAAS, either at the time of SRE installation or remotely any time thereafter.
• Remote installation and activation eliminates the need for separate truck-roll, service calls, and onsite IT personnel.
Flexible ordering options
• Customers have flexibility to order Cisco WAAS Software either along with SRE modules for a preinstalled WAAS version or separately to remotely install and activate WAAS software on predeployed SRE modules.
Integrated module
• Cisco SRE Modules have a small physical and carbon footprint, reducing administrative costs and saving energy costs.
Dedicated onboard processing, memory, and hard drive
• Dedicated hardware resources on Cisco SRE Modules help ensure maximum concurrent routing and application performance.
RAID-1 hard-drive redundancy on Cisco SRE 900 Service Module (SM)
• One-to-one hard-drive redundancy increases the availability and robustness of the network.
• Hard drives are field-replaceable and hot-swappable.
Integration with Cisco ISR G2 and Cisco IOS® Software
• Cisco WAAS on Cisco SRE Modules can be configured through Cisco Configuration Professional or the Cisco IOS Software command-line interface (CLI).
• A single-screen configuration option and proactive setup diagnostics enhance ease of deployment.
Management Solutions
Network management applications are available to configure and manage Cisco WAAS and Cisco SRE Modules from the deployment phase to the operational phase. They help to lower operating expenses and improve network availability by simplifying and automating many of the management tasks.
Table 2 lists network management solutions for Cisco WAAS on Cisco SRE Modules.
Table 2. Network Management Solutions for Cisco WAAS on Cisco SRE Modules
Cisco Configuration Professional is a GUI device-management tool for Cisco IOS Software and Cisco SRE Modules. Easy-to-use wizards simplify Web Cache Communication Protocol (WCCP) configuration.
Networkwide deployment, configuration, monitoring, and troubleshooting
CiscoWorks supports the basic platform services of the integrated services routers and provides added-value support for Cisco SRE Modules, enabling the management and distribution of software images to the Cisco SRE Module and thereby reducing the time and complexity associated with image management.
Cisco WAAS deployment, configuration, and monitoring
Cisco WAAS Central Manager is used to centrally configure, manage, and monitor a topology of Cisco WAAS platforms.
