Network Quality Testing

The following tests are being performed on your network and may take a considerable amount of time. After completion of the tests, you may contact a sales engineer whom will discuss the findings of your tests.

Test Descriptions

Capacity

The line capacity test measures the maximum capacity of a connection without the inherent overheads of TCP. The test is performed over a UDP connection and reports the maximum download and upload data transfer rates in conjunction with the packet to data ratios. The test profile is designed to answer the important question of ‘How much data can a connection sustain before data is lost?’. In addition, the packet to data ratio allows the test to highlight any packet level thresholds that affect the data throughput and data quality. The testing packet/data profile can be easily customized, allowing quick comparison tests to determine which configurations of packet size versus data volume deliver the best performance and quality of service. This ability to analyze connection throughput without inherent TCP window limitations is well-suited for pre-qualification testing, network provisioning, benchmarking and capacity testing.

Firewall

The firewall test checks to see whether the client can communicate out on certain ports.

Route

The network route test provides valuable insight to the path of a connection and helps uncover devices and networks causing slow response (latency) and/or loss of data packets. This is of particular value when troubleshooting remote connection problems traversing the public Internet. The map view provides a geographical route of the connection, which helps determine if the latency values correspond to the relative distances between hops. For instance, a transatlantic hop will naturally have a higher latency value than would a hop between two nearby cities. In addition, the network provider for each hop is reported for further investigation.

Speed

Capacity Speed tests a connection over multiple connection threads and is not usually a measure of how a connection will perform when used for most web applications, for example to view a video or listen to music. The Capacity Speed is a measure of the TCP data rate a connection can sustain, however it is unlikely to provide results that reflect the user's real experience.

VOIP

This VoIP test measures the quality of the network connection for by simulating a VoIP call using the G.711 (64 Kbps) codec. The VoIP test supports simulation of voice traffic for any number of lines, along with most popular codec setting and custom payloads. The ability to customize the VoIP traffic to fit with a particular VoIP provider environment facilitates pre-qualification of networks for VoIP deployments, and identification of cause of poor VoIP call quality.
