In order to solve the problem of dimensioning VoIP networks we focus on the aggregated VoIP links. These dimensioning procedures undoubtedly play an important role in efficiently operating extreme telephony networks like call centers and Small

The paper looks at the symmetrical services with virtual private network (VPN) connections, security and end-to-end quality of service (QoS), thus offering a guideline to service providers and end-users to select the services that best suite their needs. CPEs based on the symmetrical DSL technology are widely deployed, however there are no published results of their performance measurements. Our aim is to fill these gaps, as the work of benchmarking DSL modems with different protocol stacks is of interest to network operators. This article reports upon benchmarking results, i.e., presents a series of measurement results of five CPEs using symmetrical DSL lines for connection to the central office. Throughput, IP packet latency and IP packet-loss statistics of these transceivers are analyzed and compared. Bridged, routed, and PPP configurations are investigat...
