How To Use The Cisco Wide Area Application Services (Waas) Network Module

Cisco Wide Area Application Services (WAAS) Network Module The Cisco Wide Area Application Services (WAAS) Network Module for the Cisco Integrated Services Routers (ISR) is a powerful WAN optimization and application acceleration solution that enables branch office server consolidation, improves performance for centralized applications, and provides remote users with LAN-like access to applications, storage, and content across the WAN. Product Overview Distributed organizations face significant challenges in the deployment, management, and protection of remote office infrastructure, while at the same time needing to deliver increasingly rich application content and services to remote users. While performance and scalability constraints imposed by the WAN directly impact the ability of a remote worker to maintain productivity, there is a conflicting pressure to centralize distributed application and file services infrastructure into corporate data centers. Cisco WAAS enables organizations to centralize applications and services in the data center and to control the explosive growth in bandwidth requirements generated by new applications and business processes, while improving throughput and responsiveness for existing applications in a transparent manner. This enables collaborative applications, reduces costs, and helps organizations meet regulatory compliance requirements, while leveraging current infrastructure and IT resources. The Cisco WAAS Network Module belongs to the Cisco Wide Area Application Engine (WAE) family of network modules and appliances that host the Cisco WAAS Software. The Cisco WAE platforms deployed with Cisco WAAS overcome performance barriers created by the WAN through a sophisticated combination of application acceleration and WAN optimization techniques that mitigate application and transport latency, improve throughput, and minimize WAN bandwidth consumption for any TCP based application. The Cisco WAAS Network Module simplifies deployment and management by physically integrating with the Cisco ISR as an add-on module and logically through the transparent integration of Cisco WAAS with the existing network, allowing preservation of existing network policies, automatic discovery across any network topology, and end-to-end application traffic visibility for ease of monitoring, control, and troubleshooting. The Cisco WAAS Network Module combined with the Cisco ISR offers customers a WAN optimization and application acceleration solution that significantly lowers total cost of ownership (TCO), dramatically improves application performance, optimizes WAN utilization, and simplifies data protection in an easy-to-deploy package.

Customer Benefits The Cisco WAE product family of network modules and appliances provides customers with an enterprise-class platform for hosting the Cisco WAAS solution, offering the following benefits: Cost savings through infrastructure consolidation Cisco WAAS helps organizations consolidate remote-office server infrastructure in the data center, including file servers, web servers, e-mail servers, application servers, and database servers. Consolidating server infrastructure minimizes deployment, operational, and management costs, improves data availability, facilitates compliance with regulatory mandates and enables robust business continuity and disaster recovery processes. Improved productivity through LAN-like performance Cisco WAAS incorporates application-specific acceleration as well as WAN optimization to enable near-lan performance for accessing centralized applications over the WAN, increasing employee productivity and collaboration across all branch application services including web, file, video, e-mail, and enterprise applications. Simplified data protection With Cisco WAAS, IT organizations can apply standard backup, retention, storage management, and recovery procedures while reducing the IT overhead required to support remote locations. Business continuity and disaster recovery policies can be maintained at considerably lower costs and risks than before. Transparent integration Cisco WAAS integrates transparently with existing client, server, storage, and network infrastructure (Figure 1). Optimizations provided by Cisco WAAS are transparent and require no changes to the infrastructure. Unlike many WAN optimization products that use TCP encapsulation, Network Address Translation (NAT) static tunnels, or dynamic tunnels, the Cisco WAAS solution provides WAN optimization capabilities without manipulating information that is vital for enabling value-added services that are hosted within the network infrastructure. By providing packet network transparency and preserving IP and TCP header information, Cisco WAAS is able to interoperate with current and future Cisco IOS Software deployments of advanced network services such as Quality of Service (QoS), NetFlow, Access Control Lists (ACLs), Optimized Edge Routing (OER), IP service-level agreements (SLAs), Router and Link redundancy, as well as other Cisco products such as the Cisco PIX Firewall.

Ease of deployment The Cisco WAAS Network Module eases deployment, both physically and logically, lowering deployment and maintenance costs. Deployment in the Cisco ISR The Cisco WAAS Network Module, when ordered with a Cisco ISR ships with the network module already inserted in the router as an integrated WAN optimization and application acceleration package. Deployment in the customer network is simplified and only requires one consolidated rollout to the branch. When customers order the Cisco WAAS Network Module for installation in a Cisco ISR running in a production network, the network module can be easily deployed into the router, without requiring modifications for extra rack space, power cords or cabling. Redirection-based interception The Cisco WAAS Network Module is logically deployed using Web Cache Communication Protocol Version 2 (WCCPv2), providing transparent network interception and redirection of packets, high-availability clustering, and load sharing. Alternatively, Policy Based Routing (PBR) can be employed to deploy the Cisco WAAS Network Module in a high-availability configuration with failover support. Lowered operational costs The Cisco WAAS Network Module lowers TCO and maximizes investments in the Cisco ISR No incremental support costs The Cisco WAAS Network Module is covered under Cisco maintenance service for the router and does not require any additional support or service contracts. This leverages investments in the branch rprovides an extremely costeffective total cost of ownership (TCO) model for the enterprise branch office. Dedicated and isolated hardware A service interruption on the Cisco WAAS Network Module does not affect services on the router; the separate hardware resources for the Cisco WAAS Network Module maximizes performance and availability: Physical space savings The Cisco WAAS Network Module uses a single network module slot in a Cisco ISR and does not consume additional rack space. Simple power and cable management The Cisco WAAS Network Module takes advantage of the router s power options, including DC power and redundant power. Designed for the enterprise Cisco WAAS and Cisco WAE solutions are designed based on the experience gathered from thousands of enterprise deployments, to be part of an extensible architecture for the branch office. They are highly synergistic with existing hardware, software, and administrative procedures to minimize disruption and accelerate time to deployment, while transparently preserving network policies such as NetFlow, QoS classification, prioritization, queueing, shaping, policing, ACLs, load balancing, and high availability. Product Line The Cisco WAE product line includes network modules and appliances that address varying customer needs based on branch size, bandwidth availability, and usage patterns and are designed to scale to very large enterprise wide deployments. The Cisco WAE appliances are deployed symmetrically as edge devices at branches and as core devices at the data center as shown in Figure 2. For more details on the Cisco WAE appliances please refer to the Cisco WAE appliance datasheet. The Cisco WAAS Network Modules are offered in two configurations to address the needs of enterprise branch offices and are designed for deployment as edge devices.
