Abstract
A method for end-to-end network testing in a Voice over Internet Protocol (VoIP) network. The method includes generating a signature signal at one compatible device, transmitting the signature signal to another compatible device, receiving that signature signal and comparing it to a recognized signal. The method also includes storing the received signal for a technician to evaluate at a later time and computing a quantitative value for the Quality of Service (QoS). The compatible device can be a switch, a gateway, an end device, etc. As described, this technique requires no dedicated test equipment and should provide an advantage to the user and manufacturers of VoIP equipment.
Claims20
A method for network testing in a voice over internet protocol network comprising:
- generating a signature signal at a first compatible device;
- transmitting said signature signal to a second compatible device;
- receiving said signature signal at said second compatible device;
- and
- comparing said received signature signal to a recognized signal at said second compatible device.
A VoIP test enabling system comprising:
- a transmission module operative to generate a signature signal and send said signature signal through a voice over internet protocol network;
- a testing module operative to receive said transmitted signature signal and compare said signature signal with a stored recognized signal;
- and
- a plurality of compatible devices, wherein at least one compatible device comprises said transmission module and at least another compatible device comprises said testing module.
An end-to-end network testing method in a voice over internet protocol network comprising:
- generating a signature signal at a switch;
- transmitting said signature signal to a compatible device, wherein said compatible device is adapted to capture said signature signal;
- and
- comparing said signature signal to a recognized signal at said compatible device.
