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. Citrix SD-WAN can help you effectively and economically increase WAN throughput with features like dynamic routing, WAN virtualization, and WAN optimization to accelerate enterprise applications and ensure the performance and availability of mission critical applications across your branch network.
Application Aware Virtual WAN
Citrix SD-WAN creates a reliable WAN from diverse network links, including MPLS, broadband, and wireless, continuously measuring and monitoring each link for loss, latency, jitter and congestion. Link outages and errors are mitigated by Citrix SD-WAN’s ability to move traffic off poor performing links without impact to the applications, resulting in predictable and consistent performance. With the dynamic router capability, 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 to provide high performance for large file transfers.
Application QoS for Assured Delivery
Citrix SD-WAN identifies applications through deep packet inspection technology that results in the industry’s highest accuracy and deepest granularity. Application and application elements can be grouped into different categories with different priorities and bandwidth guarantees. With the deep, granular application awareness combined with network performance, the platform can ensure that critical applications (or critical application elements) receive priority and are routed across the highest-quality link. Lower quality links are used for lower priority applications that can tolerate higher latency. The Citrix SD-WAN endpoints also communicate with each other on congestion conditions, allowing sending devices to adjust transmission rates to match network capacity.
Application and WAN Optimization
Through features such as TCP flow control, data compression, de-duplication and protocol optimization, Citrix 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, Citrix SD-WAN can optimize video delivery within Citrix Virtual Apps and Desktops environments as well as for popular websites and internal video content repositories.
Dynamic Routing for Branch Simplification
Citrix SD-WAN provides an alternative to the legacy branch router, enabling a simpler branch network with lower infrastructure and support costs. Multiple overlay routed networks can be software defined, with separate policies and security rules applied to each. With Dynamic Routing, Citrix 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. With Dynamic Routing, Virtual WAN, QoS, and WAN Optimization functionality all available in a single appliance, Citrix SD-WAN remains the most complete solution for branch networking.
Integrated Firewall for Complete Security
Citrix SD-WAN brings multi-faceted strong data protection to the branch network, from link layer security to a stateful firewall function. The firewall integrates with the application QoS to allow security policies to be centrally defined by application or application element, allowing IT to limit access by applications or application elements, or both. Zone support plus segmented data provides a rich toolset for separating traffic and limiting where it can go. And finally, Citrix SD-WAN provides strong encryption as data crosses public and private networks while easily integrating with cloud web gateways.
Management and Visibility
To ensure great user experiences, enterprise IT must be able to quickly and easily deploy new sites on the network, easily define network and application policides, and identify the sources of problems in application delivery. Citrix SD-WAN allows centralized policy definition across all network services and zero touch deployment, radically simplifying the time and effort to turn up a new location on the WAN. Automatic bandwidth detection and adaptive bandwidth control simplifies the detection of WAN and provides detailed reporting on the true bandwidth available on each link over time. Through its integration with Citrix Networking Insight Center, Citrix SD-WAN monitors how well applications are being delivered to users in the branch. By leveraging AppFlow® data reporting formats, Citrix SD-WAN can also export data to third party applications that provide network and application intelligence.
Reliable Hybrid WANs
Citrix SD-WAN appliances measure latency, jitter and loss to create a "map" of the network underlay. This map is used to route each application to the best path through the network and ensure that the user experience is high quality.
Companies using Citrix technology for remote desktop will benefit from the integrated support for those products in the Citrix SD-WAN platform. With integrated HDXTM technologies, Citrix SD-WAN accelerates, controls and optimizes virtual desktops delivered by Citrix Virtual Apps and Desktops® and virtual applications delivered by Citrix Virtual Apps® 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 Citrix ADC Client plug in.
