“Citrix Ready” WAN Optimization: Fully certified and jointly supported by Citrix for used with Citrix HDX XenApp and XenDesktop solutions. Preconfigured acceleration for XenDesktop and XenApp using Citrix’s default security and other configuration settings enables “out of the box” deployments that scale securely while enabling high performance over the WAN.

Cisco WAAS Central Manager: New HTML 5 user-friendly interfaces and improved navigation give more detailed visibility into application performance, pass-through traffic, and the control and monitoring of specific context-aware devices, including clusters.

Market Trends Addressed by Cisco WAAS Software Version 5.0

Natively secure applications: At an increasing rate, application vendors are providing encryption at the application layer rather than relying on transport-level encryption such as SSL. Such trends require a smart application acceleration solution that works natively, out of the box, to help ensure a high-quality end-user experience without jeopardizing standards-based security protocols.

Desktop and application virtualization: Enterprises are increasingly adopting desktop and application virtualization solutions for various reasons: compliance, end-of-life extension, operational efficiencies, savings in capital expenditures and operating expenses, network agility, etc. VDI places an increasing burden on the WAN as application performance, security and manageability expectations need to be maintained as things shift into a VDI environment, increasing the pressure on IT to deploy an agile and optimized WAN.

Public and virtual private clouds: Enterprises are looking to the cloud to reduce IT costs and accelerate delivery of new applications to end users. Organizations such as the U.S. government, as well as many private companies, have mandated that IT departments investigate cloud-based offerings as part of their internal sourcing and outsourcing decisions. To facilitate this cloud-based model, a WAN optimization solution should be able to intelligently pool and provision resources elastically in a simplified manner with excellent manageability for enterprise wide deployments.

Branch-office and data center simplification: Organizations want simple enterprise wide deployment of multiple on-demand cloud-ready services with the smallest footprint possible and high return on investment (ROI).

Software delivery of network applications: This trend continues to accelerate with the proliferation and maturation of server virtualization technologies from vendors such as VMware, Citrix, and Microsoft. In addition to challenges faced by VDI, the WAN must now provide a state-of-the-art secure cloud connection. Therefore, a WAN optimization solution must be transparent and jointly validated and supported by leading industry vendors.

Security and data protection: Certain regulatory requirements, including the Payment Card Industry (PCI), Health Insurance Portability and Accountability Act (HIPAA), Sarbanes-Oxley, and Federal Core Desktop initiatives, are mandating stringent security for the transmission of sensitive data, and security standards continue to evolve in response to increasing numbers of compromised systems. The WAN must not only optimize applications and data, but also protect them.

Unique Advantages of Cisco WAAS

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

Cisco WAAS offers the most choices for WAN optimization with the broadest portfolio on the market today:

Software-based WAN optimization solutions

- Cisco WAAS Software on the Cisco Integrated Services Router (ISR) Generation 2 (ISR G2) platform provides router-integrated, on-demand WAN optimization for branch offices. The Cisco Services-Ready Engine (SRE) Modules on the Cisco ISR G2 platform decouples software services from the underlying hardware and can deliver WAN optimization as an on-demand service as required by business objectives and IT budget. This approach makes better use of existing investments while offering business agility.

- Cisco Virtual WAAS (vWAAS) is a virtual appliance that accelerates business applications delivered from private and virtual private cloud infrastructure, helping ensure an optimal user experience. Cisco vWAAS enables cloud providers to rapidly create WAN optimization services with little network configuration or disruption. vWAAS employs policy-based configuration in Cisco Nexus® 1000V Series Switches, which allows association with application server virtual machines as they are instantiated or moved.

- Cisco WAAS Express extends the Cisco WAAS product portfolio with a small-footprint, cost-effective Cisco IOS® Software solution integrated into Cisco ISR G2 devices to offer bandwidth optimization capabilities. Cisco WAAS Express increases remote user productivity, reduces WAN bandwidth costs, and offers investment protection by interoperating with existing Cisco WAAS infrastructure.

- Cisco WAAS Mobile delivers bidirectional compression, application-specific accelerators, and flow optimizers for mobile and remote users in situations in which neither an appliance nor a branch-office router is available or practical, or for public cloud environments that cannot support an appliance.

Full appliance portfolio

- Branch-office appliances support Cisco WAAS virtual blades for local hosting of branch-office IT services, reducing the branch-office footprint.

- Scalable data center platforms support small to large data centers across a wide range of deployment scenarios and price points.

Cisco WAAS also offers a proven end-to-end architectural approach with Cisco Validated Designs to reduce total cost of ownership and ease deployment challenges.

Cisco WAAS is the only WAN optimization solution that has published jointly validated designs with major application vendors such as Oracle, SAP, Microsoft, and IBM. Validated designs assist Cisco customers by offering best practices to successfully incorporate IT infrastructure such as Cisco switches, routers, security devices, and servers, thus significantly reducing the risk of deploying WAN optimization to accelerate these applications. Coupled with award-winning Cisco global support and advanced services, Cisco WAAS gives customers a significant set of resources to help ensure full network integration while reducing maintenance costs and deployment time.

For example, with Microsoft, Cisco has developed an optimized branch-office architecture that uses Cisco WAAS to optimize performance of centralized applications such as Microsoft Exchange, SharePoint, and file services, while most Microsoft Windows branch-office services and applications can be locally hosted on Cisco WAAS devices using Cisco WAAS virtual blades. The Cisco WAAS optimization for Microsoft Windows protocols was developed with Microsoft, and the relevant intellectual property rights (IPRs) are licensed from Microsoft.

Network Services Integration Provides Transparent, Secure, and Reliable Application Performance

Cisco WAAS transparent architecture 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, Cisco PIX® Firewall Software, Cisco ASA 5500 Series Enterprise Firewall Edition, and Cisco 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.
