"An increasing number of companies want to take advantage of the benefits of the Cloud, for example to access the same information from different corporate sites or to work together in teams at separate geographical locations. However, because of narrow bandwidths they are wary of using a suitable Cloud Computing solution," says Khaled Chaar, Managing Director Business Strategy at Pironet NDH. The new solution would sweep away these reservations. A conventional DSL connection, for example, enables several hundred office environments per location to be supported from a central Cloud Computing platform.
Information express instead of a jammed highway
With conventional data transfer, information is frequently transferred relatively inefficiently: For instance data is not adequately compressed. Certain applications also transfer their data packets individually instead of bundling them. Furthermore, the digital information is normally not prioritised: Business-uncritical applications also require a large bandwidth, which results in unnecessarily long response times for time-critical applications, such as ERP solutions, or video conference systems not functioning at all.
To solve these problems, the Cloud Accelerator employs a combination of three technical components: Compression algorithms ensure that data is bundled when transferred. In addition, Protocol optimisation guarantees that a large number of individual data packets are combined efficiently in a single packet, thus dramatically reducing unnecessary TCP headers, in other words the protocols for controlling data transfer. The third element is intelligent caching, i.e. saving frequently required data locally so that it does not have to be transferred anew each time it is required. All three components together reduce the data volume on the WAN and lead to optimum utilisation of the available bandwidth.
Same connection, higher speed
The result: Web and office applications, applications based on Microsoft SQL and also entire workstation environments start up and respond more quickly. Data can also be called and saved faster. The actual acceleration rate depends on the application environment concerned, the bandwidth available and the existing approaches for optimising data traffic. A prerequisite for WAN optimisation is that the corporate sites are connected to Pironet NDH's Corporate Network.
"Network expansion in Germany has made great progress in many regions, but data traffic is increasing disproportionately quickly compared to the speed of the internet connections," says Mr Chaar. "Optimisation technologies for Wide Are Networks are therefore ideal tools for operating Cloud applications with just as high a performance as with local installations, even with low bandwidths."
