Citrix NetScaler SD-WAN Product Introduction

The distributed enterprise requires a solution that ensure users remain connected at all times. One that strengthens security and that provides end-to-end visibility without adding complexity. Citrix NetScaler SD-WAN is that solution - built for your distributed enterprise.

Why NetScaler SD-WAN

Businesses rely on branch offices or remote employees to serve customers, to be near partners and suppliers and to expand into new markets. As application and desktop virtualization increase or applications move to the cloud, IT managers face the challenge of providing these applications without a performance penalty to branch and mobile users. NetScaler SD-WAN can help you effectively and economically increase WAN throughput while accelerating enterprise applications and ensuring the performance and availability of mission critical applications.

  • Maintain high performance for mission critical applications even when a network link fails
  • Improve the virtual desktop experience to branch-office and mobile users and accelerate traditional enterprise applications
  • Expand WAN capacity with low-cost broadband connections, while maintaining MPLS-level quality and reliability
  • Support cloud migration with integrated security to protect enterprise data
  • Simplify IT with integrated routing and WAN Optimization to reduce network footprint
  • Secure data across the WAN and to the cloud with strong encryption, application- level security policies and data segmentation
  • Gain visibility into application delivery in order to proactively manage the user experience

Key Features  

Application Aware Virtual WAN

NetScaler SD-WAN creates a reliable WAN from diverse network links, continuously measuring and monitoring each link for loss, latency, jitter and congestion. Link outages and errors are mitigated by NetScaler SD-WAN’s ability to move traffic off of poor performing links without impact to the applications. Mission critical applications are always routed across the paths with the fastest transit time, real-time application traffic can be duplicated to guarantee no loss and traffic from high bandwidth applications can be balanced across multiple links. With NetScaler SD-WAN, this results in a high bandwidth, low cost WAN that is reliable and ensures high application quality.

Application QoS

NetScaler SD-WAN identifies applications using the WAN and applies default or user defined rules to ensure that critical application receive priority and are routed across the highest- quality link. Lower quality links are used only as much as necessary, and then only for applications that can tolerate higher latency. Packet reordering and packet loss mitigation features reduce jitter and packet loss.

Application Optimization

Through features such as TCP flow control, data compression, de-duplication and protocol optimization, NetScaler SD-WAN can improve the end-user experience as well as provide a reduction in WAN bandwidth expenses. And with video usage on the rise, NetScaler SD-WAN can optimize video delivery within Citrix XenDesktop environments as well as for popular websites and internal video content repositories.

Dynamic Router

NetScaler SD-WAN provides an alternative to the legacy branch router, enabling a simpler branch network with lower infrastructure and support costs. With Dynamic Routing, NetScaler SD-WAN can seamlessly participate in your routing topology in overlay mode for easy network insertion or operate in edge mode for a streamlined branch network with assured application delivery. By adding routing to the WAN Optimization and Virtual WAN functionality integrated into a single physical or virtual appliance, NetScaler SD-WAN remains the most complete solution for branch networking.

Segmented and Secure Data Transmission

NetScaler SD-WAN brings strong data protection to the network. Multiple overlay networks can be software defined, with separate policies and security rules applied to each overlay. This creates data segementation, allowing extra protection for data such as payment or health information. NetScaler SD-WAN also provide strong encryption as data crosses public and private networks including to and from the cloud and tight integration with cloud-delivered web gateways.

Management and Visibility

To ensure great user experiences, enterprise IT must be able to quickly and easily identify the sources of problems in application delivery. Through its integration with Citrix NetScaler Insight Center, NetScaler SD-WAN monitors how well applications are being delivered to users in the branch. By leveraging AppFlow® data reporting formats, NetScaler SD-WAN can also export data to third party applications that provide network and application intelligence.

Reliable Hybrid WANs

NetScaler SD-WAN appliances measure latency, jitter and loss to create a "map" of the network underlay. This map is used to direct each application to the best path through the network and ensure that the user experience is high quality.

Built in integration with XenDesktop and XenApp

Companies using Citrix technology for remote desktop will benefit from the integrated support for those products in the NetScaler SD-WAN platform. With integrated HDXTM technologies, NetScaler SD-WAN accelerates, controls and optimizes virtual desktops delivered by XenDesktop® and virtual applications delivered by XenApp® for branch users, improving user experience and productivity by providing fast, secure remote access. And extend the application acceleration benefits to mobile users with the NetScaler Client plug in.

Customer Stories

Orianna Health

Provider operating approximately 6,000 beds across 56 skilled nursing facilities.

Problem: New electronic medical record (EMR) project required immediate bandwidth upgrades, but MPLS was expensive

Result: NetScaler SD-WAN gave them a ten month payback on the purchase versus scaling existing MPLS connections plus more reliable applications and QoS for VoIP.

HMS Host

World’s largest provider of food, beverage, and retail services with over 200 airport locations across the U.S.

Problem: Needed fast, optimized access from point of sale terminals for its credit-card transaction processing application.

Result: The NetScaler SD-WAN solution reduced WAN data by 90% and proved to be 20% cheaper than the incumbent solution.

Cornerstone Mortgage

Twelfth largest U.S. retail mortgage bank with over 1,250 employees across 84 branches in 48 states.

Problem: Fast growing bank needed reliable access to its core, centralized loan processing application published via XenApp.

Result: After deploying NetScaler SD-WAN solution, loan-processing times for remote workers dropped from 3 hours to 45 minutes.

Royal Caribbean

Large cruise line with 22 ships and multi-lingual reservation centers worldwide.

Problem: Improve user experience for XenApp and XenDesktop in call centers and ships.

Result: Decided to refresh its WAN optimization equipment and determined that NetScaler SD- WAN provided significantly better performance.

We're able to utilize commercial-grade broadband services along with 4G/LTE and our Metro-E fiber to facilitate our network reliability which is a key for our organization because, as we’re a full XenDesktop environment, we need to make sure we have full uptime.
