Abstract
Systems, methods, architectures, mechanisms or apparatus for automatically pinpointing specific service bottlenecks within a network services chain delivery network services to a subscriber by remotely and/or automatically invoking multiple quality of service (QoS) tests at customer premises equipment (CPE) such as a modem, wireless access point (WAP), subscriber device and the like.
Claims19
A method of verifying quality of service (QoS) of network services delivered to a subscriber via a network services delivery chain including provider equipment (PE) and customer premises equipment (CPE), comprising:
- receiving, at a PE network management system, a QoS verification request associated with a subscriber device and a modem via which the subscriber device accesses network services;
- performing, at a QoS testing server configured to communicate with the subscriber device via an access network communications channel established therebetween, a first test to determine a QoS delivered to the subscriber device, said first test comprising transferring data between said subscriber device and a first QoS testing server to determine thereby corresponding upstream and downstream bandwidth measurements;
- performing, at a QoS testing server configured to communicate with the modem via an access network communications channel established therebetween, a second test to determine a QoS delivered to the modem, said second test comprising transferring data between said modem and a second QoS testing server to determine thereby corresponding upstream and downstream bandwidth measurements;
- in response to the QoS delivered to the modem exceeding the QoS delivered to the subscriber device by a threshold amount, performing a subscriber fault action comprising transmitting toward said subscriber a message indicative of a subscriber network problem and offering a qualified device to said subscriber in response to determining, at the PE network management system, that one or more devices associated with said subscriber are associated with a non-qualified device;
- and
- in response to the QoS delivered to the modem not satisfying a required QoS level, performing a provider fault action.

- in response to the QoS delivered to the modem not satisfying a required QoS level, performing a provider fault action;
- storing results of said first and second test in a database within a non-transitory computer readable medium associated with the PE network management system;
- receiving, at the PE network management system, a QoS history request associated with a subscriber device and the modem via which the subscriber device accesses network services;
- retrieving, from said database, corresponding stored prior first and second test results;
- and
- transmitting, toward a source of said QoS history request, said retrieved prior first and second test results.

An apparatus for verifying quality of service (QoS) of network services delivered to a subscriber via a network services delivery chain including provider equipment (PE) and customer premises equipment (CPE), the apparatus comprising:
- a processor configured for:
- receiving a QoS verification request associated with a subscriber device and a modem via which the subscriber device accesses network services;

- performing, at a second QoS testing server configured to communicate with the modem via an access network communications channel established therebetween, a second test to determine a QoS delivered to the modem said second test comprising transferring data between said modem and said second QoS testing server to determine thereby corresponding upstream and downstream bandwidth measurements;
- in response to the QoS delivered to the modem exceeding the QoS delivered to the subscriber device by a threshold amount, performing a subscriber fault action comprising transmitting toward said subscriber a message indicative of a subscriber network problem and offering a qualified device to said subscriber in response to determining, at the PE network management system, that one or more devices associated with said subscriber are associated with a non-qualified device;
- and
- in response to the QoS delivered to the modem not satisfying a required QoS level, performing a provider fault action.
