Network Services Integration Provides Transparent, Highly Secure, and Reliable Application Performance
The transparent architecture of WAAS can enable 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 allow for 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).
● 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).
● WAAS integrates with all Cisco firewalls—including Cisco IOS Firewall, Cisco PIX® Firewall Software, Cisco ASA 5500 Series Enterprise Firewall Edition, and Cisco Catalyst® 6500 Series Firewall Services Module—to provide an industry-leading solution that gives customers full stateful firewall inspection and network virus-scanning capabilities for accelerated traffic.
● For inline deployments, WAAS offers a low-latency, voice-over-IP (VoIP), traffic-bypass feature that has been stress-tested with Cisco VoIP test beds.
Features and Benefits
WAAS also offers a proven, end-to-end architectural approach with Cisco Validated Designs to reduce total cost of ownership (TCO) and ease deployment challenges.
WAAS is currently 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, 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 WAAS to optimize performance of centralized applications such as Microsoft Exchange, SharePoint, and file services. The WAAS optimization for Microsoft Windows protocol was developed with Microsoft, and the relevant intellectual property rights (IPRs) are licensed from Microsoft.
Table 5 summarizes the main features and benefits of WAAS.

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.
|
Benefit: Application acceleration:
● Improve employee productivity
● Consolidate branch-office servers
● Centralize branch-office IT resources such as storage and backup tapes, and reduce operating costs
|
Features
●
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 (Server Message Block [SMB]); Microsoft Exchange (Messaging API [MAPI] and MAPI over SSL); encrypted MAPI (EMAPI), HTTP, and HTTPS applications such as Oracle, SAP, and Microsoft SharePoint and Outlook Web Access (OWA); Microsoft Windows print services; UNIX Network File System (NFS); and Citrix ICA. These features improve end-user application response times, significantly improving employee productivity.
●
Content prepositioning: You can use centralized policy-based file distribution and prepositioning can be used to push files to edge WAAS devices, accelerating software patch distribution and file access for all users.
|
Benefit: Ease of initial and ongoing deployment |
Features
●
Network transparency: WAAS preserves all existing network services.
●
Client, server, and application transparency: No modifications to clients, servers, or applications are needed.
●
Automatic peer discovery: WAAS devices automatically discover peers, reducing the number of configuration steps.
●

The program walks you through a series of questions and enables the corresponding Cisco AppNav Controller, container, interface, and connected application configurations.
|
Benefit: Flexible deployment options for cloud computing |
Features For private and virtual private cloud environments:
●
Agility: Implement agile virtual machine—based deployments on standard x86 servers, such as Cisco Unified Computing System (Cisco UCS) servers.
●
Application-specific WAN optimization: Use Cisco Nexus
® 1000V Series port profiles to create value-added WAN optimization services on a per-application basis in your catalog of cloud services (for example, use vWAAS only for Microsoft SharePoint or Exchange) for optimized delivery to remote branch-office users.
●
Flexible scale-out of WAAS deployment: Using policy-based configuration in the Cisco Nexus 1000V Series Switch, you can associate 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 helps 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.
●
AppNav-XE on the Cisco 4000 Series ISR, Cisco Cloud Services Router 1000V Series (Cisco CSR 1000V Series) and Cisco ASR 1000 Series Aggregation Services Routers: As a part of Cisco IOS-XE Software, the AppNav-XE component is made up of a distribution unit called the Cisco AppNav Controller and service nodes.
Advantages of using the AppNav-XE component:
● It can intelligently redirect new flows based on the load on each service node. This includes the loads of individual Layer 7 application accelerators.
● For flows that do not require any optimization, service nodes can inform the AppNav Controller to directly pass through the packets, thereby reducing the latency, resource utilization, and usage.
● The AppNav-XE component supports Virtual Route Forwarding (VRF) so that VRF information is preserved when traffic returns from a service node.
● For special applications such as MAPI (Exchange) and VDI (Citrix), the AppNav-XE component helps ensures that flows from the same client and destined to the same server and server port are redirected to the same service node.
● You can use an AppNav Controller group to optimize asymmetric flows. An asymmetric flow occurs when the traffic in one direction goes through one AppNav Controller and the return traffic goes through a different AppNav Controller, but both AppNav Controllers redirect the traffic to the same service node.
● Inter-router high availability, where, if one router goes down, the traffic can be re-routed to a different router within the AppNav Controller group, keeping the traffic flows uninterrupted.
● Intra-router high availability of the AppNav Controller on Cisco ASR 1000 Series platforms that have dual RP route processors or dual Cisco FabricPaths. This means that if the active RP route processor fails, the standby route processor RP takes over; or if the active FP FabricPath fails, the standby FP FabricPath takes over and the flows continue uninterrupted. The intra-router high- availability feature is available only on Cisco ASR 1000 Series platforms.
For public cloud environments
●
Accelerated 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, WAAS Mobile can be used to accelerate access to hosted infrastructure-as-a-service (IaaS) applications delivered from public cloud platforms, such as Amazon.com, to remote mobile users.
●
Cloud-agnostic: vWAAS can be deployed in public clouds with the Cisco Nexus 1000V Series to obtain benefits similar to those for private clouds. The vWAAS solution is public-cloud-agnostic.
