Unique Cisco WAAS Advantages

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 Cisco ISR Generation 2 (G2) 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 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 in cloud-based environments by using 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 or 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 Offers a Proven End-to-End Architectural Approach with Validated Designs to Lower TCO 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.

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.
  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 (Messaging API [MAPI] and MAPI over SSL); HTTP and HTTPS applications such as Oracle, SAP, and Microsoft SharePoint and Outlook Web Access (OWA); Microsoft Windows print services; and UNIX Network File System (NFS). These features improve end-user application response times, significantly improving employee productivity.
  Content prepositioning: Centralized policy-based file distribution and prepositioning can be used to push files to edge Cisco WAAS devices, accelerating software patch distribution and file access for all users.

Ease of initial and ongoing deployment

  Network transparency: Cisco WAAS preserves all existing network services.
  Client, server, and application transparency: No modifications to clients, servers, or applications are needed.
  Automatic peer discovery: Cisco WAAS devices automatically discover peers, reducing configuration steps.
  Quickstart wizard: Use of the wizard eliminates many configuration steps. The wizard includes defaults for faster deployment.
  Management and monitoring: Intuitive workflow-based management and real-time monitoring are provided. Diagnostic and troubleshooting tools help reduce mean time to resolution.

Flexible deployment options for cloud computing

  Application-specific WAN optimization: Use Cisco Nexus 1000V Series port profiles and vPath to create value-added WAN optimization services on a per-application basis in your catalog of cloud services (for example, use Cisco vWAAS only for Microsoft SharePoint or Exchange) for optimized delivery to remote branch-office users.
  Flexible scale-out Cisco WAAS deployment: Using policy-based configuration in the Cisco Nexus 1000V Series Switch, you can associate Cisco vWAAS services with application server virtual machines as they are instantiated or moved in response to dynamic application load demand in the cloud. This capability enables cloud providers to offer rapid delivery of WAN optimization services with little network configuration or disruption to achieve a cloud consumption and delivery model.
  Multi-tenant: Cisco vWAAS reduces the hardware footprint needed for multi-tenant deployments.
  DRE on SAN: Cisco vWAAS offers an option to allow its DRE database to be hosted on the SAN to provide an improved fault-tolerant response and to support virtual machine mobility requirements.
  Validated sizing benchmarks on Cisco UCS servers: Cisco vWAAS can be hosted on any x86 server that supports the VMware ESX and ESXi 4.0 hypervisor. Sizing benchmarks and performance metrics provided on the Cisco UCS platform result in lower risk for cloud deployments.

For public cloud environments:

  Accelerate SaaS applications: Cisco WAAS accelerates SaaS applications, such as Salesforce.com, delivered from the public SaaS cloud. SaaS applications are typically HTTPS based and can be configured in an easy and scalable manner. In addition, Cisco WAAS Mobile can be used to accelerate access to hosted infrastructure-as-a-service (IaaS) applications delivered from the public cloud, such as Amazon.com, to remote mobile users.
  Cloud agnostic: Cisco vWAAS can be deployed in public clouds with the Cisco Nexus 1000V Series to obtain benefits similar to those for private clouds. The Cisco vWAAS solution is public-cloud agnostic.

Delivery of high-quality live and on-demand video

  Eliminate need for expensive WAN bandwidth upgrades
  Avoid complex configuration
  Centralize branch-office video servers
  Easy-to-deploy live video with edge-stream splitting: Automated edge-stream splitting helps ensure that only one video stream is downloaded over the WAN regardless of the number of users in the branch office who are viewing that stream.
  Recorded VoD: VoD files can be published using prepositioning on edge Cisco WAAS devices.
  Server offload: Live and on-demand video features offer server offload capabilities that can enable up to a 10 times reduction in the number of data center video servers.

Locally hosted branch-office IT services

  Reduce branch-office device footprint
  Deploy branch-office IT services with flexibility and agility
  Network-embedded virtualization: Third-party services can be hosted on isolated virtual blades. This architecture maintains native performance for WAN optimization while using the same hardware platform for additional hosted services.
  Virtual blades: This feature can be used to deploy many different Microsoft Windows and Linux branch-office services on Cisco WAAS Appliances within hours instead of the days or weeks often required for dedicated hardware-based deployments. Certified and supported hosted services include Microsoft Active Directory, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and print services using Microsoft Windows Server 2003, 2008, or 2008R2; Cisco Network Analysis Module (NAM); and Cisco Application and Content Network System (ACNS).
