Main Differentiators

Cisco WAAS offers numerous benefits that distinguish it from other WAN optimization products.

Application-Vendor Validation

Cisco WAAS is the only WAN optimization solution that has jointly published validated designs with major application vendors such as Oracle, SAP, Microsoft, and IBM. They offer best practices and significantly reduce the risk of deploying WAN optimization to accelerate these applications.

With Microsoft, Cisco has developed the optimized branch-office architecture through which Cisco WAAS is used to optimize performance of centralized applications such as Microsoft Exchange, SharePoint, and file services, while Microsoft Windows core services such as Microsoft Active Directory and print services are integrated into branch-office Cisco WAAS devices using Cisco WAAS virtual blades for local hosting. The Cisco WAAS optimization for Microsoft Windows protocols has been developed with Microsoft, and the relevant intellectual property rights (IPRs) are licensed from Microsoft.

Cisco offers joint escalation support with some major application and storage vendors to help ensure that cross-vendor concerns are appropriately addressed.

Network Integration

Cisco WAAS transparent architecture (Figure 1) enables integration into the network and preservation of existing network services, thereby making WAN acceleration easy to deploy and operate.

Network transparency and preservation of IP and TCP header information allows ease of operation and interoperability with network services such as quality of service (QoS), NetFlow, access control lists (ACLs), firewalls, Cisco Performance Routing (PfR), and IP service-level agreements (SLAs).

Cisco WAAS offers automatic discovery of optimization devices, simplifying operations for all types of WAN architectures (including Multiprotocol Label Switching [MPLS], hierarchical networks, and hub-and-spoke topologies).

Cisco WAAS integrates with all the Cisco firewalls - Cisco IOS Firewall, PIX® Firewall Software, ASA 5500 Series Enterprise Firewall Edition, and Catalyst® 6500 Series Firewall Services Module (FWSM) - to provide the only solution in the industry that gives customers full stateful firewall inspection and network virus-scanning capabilities for accelerated traffic.

For inline deployments, Cisco WAAS offers a low-latency voice-over-IP (VoIP) traffic bypass feature that has been stress tested with Cisco VoIP test beds.

Low Total Cost of Ownership

Cisco WAAS is cost effective and provides the lowest total cost of ownership (TCO) of any solution currently on the market.

By integrating Cisco WAAS into network modules or Cisco SRE Modules on Cisco ISR, Cisco WAAS reduces capital expenditures (CapEx), operating expenses (OpEx), and support costs. By reducing the number of branch-office devices needed, Cisco WAAS decreases OpEx by up to 70 percent.

Cisco WAAS virtual blades provide local hosting with centralized deployment for Microsoft Windows and Linux branch-office services while reducing the branch-office device footprint.

Cisco WAAS eliminates the need for WAN bandwidth upgrades and complex configuration for wide-scale delivery of live video to the branch office.

Feature

WAN Optimization

Eliminate or defer expensive WAN bandwidth upgrades
Transport Flow Optimization (TFO): TFO improves application packet flow under unfavorable WAN conditions such as packet loss and small initial windows while helping ensure fairness.
Data Redundancy Elimination (DRE): DRE is an advanced form of network compression that uses a bidirectional database to store previously seen TCP traffic and replace redundant patterns with very small signatures. DRE can provide up to 100:1 compression depending on the data being examined.
Adaptive Persistent Session-Based Compression: This type of compression can provide up to an additional 5:1 compression.

Application Acceleration

Improve employee productivity
Consolidate branch-office servers
Centralize branch-office IT resources such as storage and backup tapes and reduce operating costs
Protocol acceleration: Application-specific latency is reduced through a variety of application-layer techniques such as read-ahead, operation prediction, connection reuse, message multiplexing, pipelining, and parallelization, resulting in LAN-like performance despite deployment over a WAN.
Application optimizers: Protocol-specific acceleration is available for Microsoft Windows file sharing (Common Internet File System [CIFS]); Microsoft Exchange (MAPI and MAPI over SSL); HTTP and HTTPS applications such as Oracle, SAP, and Microsoft SharePoint and OWA; Microsoft Windows print services; and UNIX NFS.
