Citrix Netscaler Control SD WAN
Citrix NetScaler Control 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, Citrix NetScaler Control 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 NetScaler Control SD WAN can optimize video delivery within XenDesktop environments as well as for popular websites and internal video content repositories. Citrix NetScaler Control SD WAN provides an alternative to the legacy branch router, enabling a branch network with lower costs.
Application Aware Virtual WAN
Citrix NetScaler Control 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 Control SD WAN 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 Control SD WAN, this results in a high bandwidth, low—cost WAN that is reliable and ensures high application quality. Citrix NetScaler Control 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.
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 policies, and identify the sources of problems in application delivery. Citrix NetScaler Control SD WAN center 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 NetScaler Insight Center, Citrix NetScaler Control SD WAN monitors how well applications are being delivered to users in the branch. By leveraging AppFlow data reporting formats, Citrix NetScaler Control SD WAN can also export data to third—party applications that provide network and application intelligence.

Current SDN technologies operate at Layers 2—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—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—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 — Layer—7 services.
