WAN Optimization or Bandwidth Optimization Services in South Africa

The term "WAN or Bandwidth optimization" refers to a collection of capabilities that hone the performance of applications written for high-speed LANs when they are accessed across lower-speed and latency-prone WAN’s.

KSS has extensive experience in helping companies use WAN optimization to boost network performance along with enhancing security and improving application delivery.

WAN optimization and application acceleration are growing requirements in today's enterprises, which comprise increasing numbers of branch-office sites and remote users but consolidate application and data storage resources for regulatory compliance reasons and cost savings. By some estimates, 70 to 90 percent of enterprise resources are now accessed by remote users across a WAN, which is slower than the LAN platform for which most applications were designed and introduces distance-based latency into the networking experience.

WAN optimization functions, however, are now available to alleviate WAN traffic loads, reduce application protocol message round trips, and cache critical data to make branch-office application-access experiences "LAN-like".

Contact KSS today to accelerate your applications, optimize your bandwidth, reduce latency and improve your users experiences over the WAN!

Citrix Branch Repeater and WAN Scaler
Citrix WAN Scaler

Cisco Wide-Area Application Services (WAAS) provide a rich set of WAN optimization capabilities. Among the WAAS functions are advanced data redundancy elimination (DRE), caching, application-specific protocol acceleration, and TCP flow optimization (TFO), all of which accelerate application response times by alleviating WAN traffic loads and congestion. Cisco's new WAN Optimization platforms dramatically scale the delivery of an optimal user experience to more users, applications, and devices across the entire organization. Cisco WAAS accelerates applications, optimizes bandwidth, and enables a smooth evolution to cloud-based services.

The new Cisco WAVE Appliances: 294, 594, 694, 7541, 7571, and 8541 are 2nd generation WAN optimization solutions, delivering both a dramatic increase in performance, with the following:

Five times the performance with up to 2Gbps optimized WAN throughput
Four times the virtual services density with support for up to 6 virtual blades
Three times the scale with 150,000 TCP Connections
Substantially reduced solution footprint - third of previous footprint

Citrix Branch Repeater™ is a WAN optimization solution that accelerates application delivery to branch office users while dramatically reducing WAN bandwidth requirements and simplifying branch IT infrastructure. Branch Repeater dramatically increases productivity by providing a high definition user experience over any network. Branch Repeater also reduces costs by improving utilization of existing WAN bandwidth and by streamlining branch IT start-up and management.

The Branch Repeater product family addresses the full range of WAN optimization scenarios and delivers unparalleled application acceleration benefits—especially for Citrix XenApp™.

Many WAN optimization solutions are able to improve WAN communications by removing the TCP Slow Start process and by increasing the TCP Window Size to allow more data to pass over the WAN before an acknowledgement is required.

However, most WAN links contain additional protocols in addition to ICA. Citrix WAN Scaler can have a positive impact on the responsiveness of ICA by using its adaptive TCP flow control functionality to improve overall WAN link utilization. WAN Scaler’s implementation of TCP Congestion Control is setup in such a way that if a collision occurs on the wire, the send rate is only slightly impacted or not at all, thus allowing the protocols to continue to use the full bandwidth of the link.

WAN Scaler also modifies the TCP Window Size for the WAN link, based on the Window Scaling process. This modification means more data passes before pauses, thus allowing for faster data traversal. Both of these enhancements to WAN link utilization can improve ICA responsiveness as the purchased bandwidth will be more fully utilized.
