Radware Accelerates Web Images Delivery w/50% Compression



Radware released the "..newest version of its powerful automated web performance optimization and acceleration solution, FastView® 6 .. includes PerfectImage, proven by research to be the preferred image compression method for both higher user satisfaction and faster web page delivery" 
PerfectImage is an algorithm developed to optimize images - significantly reducing image file size while ensuring minimal image quality degradation. 
By using a Digital Camera Images (DCIM) human vision algorithm, images are carefully compressed using various image compression formats (such as JPEG, JPEG 2000, WebP, and others) so that the final image has less than 1.5% difference vs. the original image which is invisible to the human eye. Another outcome of applying PerfectImage is that the image file size can shrink by up to 80%.

The average compression ratio achieved with PerfectImage is more than 50%. If the average web page payload is 1.8MB and the average image payload is 1.1MB (59%), than applying the PerfectImage algorithm can save 550KB (30%) of payload per page. 
We applied the PerfectImage algorithm on a flight reservation commercial site. The magnifying glass shows how the image size on the original web page (before applying PerfectImage optimization) was 1.7MB and after the optimization the image payload went down to 412Kb – a 75% reduction: 



".. In addition to PerfectImage, FastView 6 also offers deeper web application acceleration, covering more resources inside each web application page. It is the first to optimize resources embedded in and rendered by JavaScript as these resources are not included directly by the web servers and are normally not optimized. FastView 6 now optimizes these tough to find files to make JavaScript oriented applications render even faster.

The technology applies advanced acceleration techniques to dynamically discover client side application calls, allowing enterprises to overcome the challenge of optimizing web pages that are built on a growing number of resources within scripts running on a client’s browser instead of being native to the server side application code

Nokia's Traffic Steering Solution Increases Capacity by 10%


Nokia Networks announced it has "solved the complexities of coordinating the dozens of load balancing and traffic steering features available in multi-technology, multi-layered and multi-vendor mobile broadband networks. The purpose of these features is to avoid network congestion by distributing the traffic across different radio network layers. 

The Nokia Traffic Steering Manager is the first all-inclusive solution to automatically direct traffic to the most effective radio network layer. This ensures more efficient use of existing infrastructure, that is, an operator can effectively increase the capacity in the network by 10%. The Traffic Steering Manager provides an easy, automated way of managing the multitude of load balancing features available in the networks today reducing related operational effort significantly, up to 70 %.




Nokia’s Traffic Steering Manager is a network-wide system that combines all radio technologies (2G, 3G, LTE and Wi-Fi; macro and small cells) as well as the core network to dynamically orchestrate the network capacity utilization. If the capacity limits are reached, value-based traffic steering, enabled by the Traffic Steering Manager, is vital to ensure the network is used according to business priorities .. On a typical mid-sized network with 32,000 3G and LTE cells, an operator can improve network efficiency, worth two million euros per annum


  • Centralized solution coordinates a multitude of load balancing and traffic steering functionality in radio networks to use all the capacity available in multi-technology, multi-layer and multi-vendor heterogeneous networks (HetNets)
     
  • Traffic is steered according to network conditions. Also other criteria like device capabilities and customer service level agreements (SLA) can be taken into account when planning efficient service delivery and network utilization
