Increase WAN throughput and reliability while improving the application experience with Citrix NetScaler SD-WAN SDN. The traditional WAN was not designed to tackle today’s application traffic. The Citrix Software-Defined WAN solution, Citrix NetScaler SD-WAN, offers a more scalable, reliable, and cloud-ready approach. Combining the intelligence of SD-WAN technology, WAN optimization, routing and application management into one comprehensive solution, Citrix NetScaler SD-WAN ensures the user experience at the branch and mobile level are just as rich and seamless as at headquarters. 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. 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 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.
Business Continuity And IT Disaster Recovery
While most business continuity and IT disaster recovery plans focus on protecting the data center, your plans should also ensure server availability and access to the business-critical apps, data, and collaboration tools that keep the business running. Remote access and WAN technologies are key, allowing people to work as usual, even during a natural emergency. Citrix networking solutions work together to form a complete business continuity and IT disaster recovery plan. They ensure service and resource availability, a seamless user experience, uninterrupted remote and branch access, and data replication. During a business continuity event, data and apps are delivered to users in the same way they’re accustomed to — whether it’s LAN, WAN, broadband, satellite, hotspot, or mobile — with the same inherent security, control, compliance monitoring, and tracking. Citrix NetScaler SD-WAN appliances continuously monitor every MPLS and broadband connection by tagging packets with sequence numbers.
Segmented And Secure Data Transmission
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 Citrix NetScaler SD WANs 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 Citrix NetScaler SD-WAN, this results in a high bandwidth, low-cost WAN that is reliable and ensures high application quality. Citrix NetScaler SD-WAN appliances measure latency, jitter and loss to create a “map” of the network underlay. This map is used to direct each app to the best path and ensure that the user experience is high quality.
Citrix NetScaler SD-WAN
Citrix 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. 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. Citrix NetScaler SD-WAN can optimize video delivery within XenDesktop environments as well as for popular websites and internal video content repositories. Citrix 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, Citrix NetScaler SD-WAN can participate in your routing topology in overlay mode for easy network insertion.

Current SDN technologies operate at Layer-2 and Layer-3 and are missing the opportunity to truly deliver on the full promise of the solution. The next-generation NetScaler platform unifies best-in-class Layer-4 and Layer-7 network services into an application control layer, and can integrate this application control with both existing transport networks and emerging SDN technologies. This application control layer can make emerging Layer-2 and Layer-3 SDN architectures completely app-driven, by using app-centric definitions and policies to simplify network design, while making the whole network more intelligent.
With its centralized management plane, NetScaler alleviates the overhead and sprawl usually associated with serving complex networking applications. Through intuitive workflows, administrators can enable provisioning and deploying of new network services on demand. The central plane also acts as a single point of visibility, providing a coherent view of the operational characteristics for all the instances running on the appliance. This software-driven approach makes it possible to successfully support the dynamic changes inherent in today’s cloud-based, app-driven environment.
Compared to the advancements in compute and storage virtualization, networking has fallen behind in fully realizing the promise of enterprise cloud computing. The dynamic nature of cloud services requires a new level of flexibility and scalability, which goes beyond the capabilities of today’s data center networks. Transitioning to Software-Defined Networking (SDN) incorporates programmability and agility into your network, enabling it to keep pace with business demands.

Citrix NetScaler was created to transform traditional networks into next-gen, app—driven enterprises. Designed for use in virtualized networks, it’s ideally suited to integrate with SDN and cloud orchestration systems. The platform combines the flexibility of virtualization with the resiliency, reliability, and performance of purpose-built network appliances. Eliminating the need for multiple physical devices, a single Citrix NetScaler can be deployed in a multi-tenant environment, while also offering traffic isolation and dedicated resources per tenant.
Administrators can rightsize instances based on the workload required per tenant, with fine-grained control over the CPU, memory, and SSL hardware resources, to achieve performance goals.
On demand cloud services and SDN allow organizations to quickly grow and transform to meet the demands of the modern workplace. Citrix NetScaler enables organizations to ensure the best security, performance and reliability whether workloads run in the data center or in an external cloud. By allowing IT to deliver every application workload at scale and with simplicity, organizations can benefit from all that cloud computing has to offer. Expanding the virtual network infrastructure portfolio.
Citrix and Cisco have delivered the Citrix NetScaler 1000V, a best in class application delivery controller that redefines Layer-4 and Layer-7 services.
