Measurement of Application-Perceived Throughput of an E2E VPN Connection Using a GPRS Network
Based on the need for secure and reliable mobile communication, this paper investigates the application-perceived throughput of an end-to-end (E2E) VPN connection using IPSec over GPRS. GPRS is of particular interest regarding performance issues due to its wide deployment but limited capacity. To this end, different encryption and authentication algorithms are considered. The throughput is measured on small time scales and interpreted with aid of summary statistics, histograms and autocorrelation coefficients. The results reveal a clear influence of the network and the chosen security solution, seen from variations of application-perceived throughput on the one-second time scale, which has to be considered when assessing the appropriateness of network for a specific task. The different statistical metrics considered will later be used in our research to maintain the security and Quality of service (QoS) of the service decided by the user.
