Abstract
The disclosure provides a system and method for providing a service in a packet-switched network at a selected Quality of Service (QoS) level. The method includes receiving a request for a service from a customer gateway at server connected to the packet-switched network; correlating the requested service to available network resources; and enabling the network to provide the requested service based on a result of the correlation.
Claims17
A non-transitory computer readable medium, accessible to a server, comprising program instructions executable by the server to:
- receive a request from a customer equipment for a service over a packet-switched network;
- determine an availability of the network to provide the service at a selected quality of service level wherein the program instructions to determine the availability including instructions to:
- estimate a current value of a front end metric selected from a group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio and wherein the front end of the network includes a portion of the network between a digital subscriber line access multiplexer (DSLAM) and a gateway at a customer location;
- and
- estimate a value of a back end metric selected from the group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio wherein the back end of the network includes a portion of the network between a video server and the DSLAM;
- and
- provide the service when the availability indicates the selected quality of service level.

A method of providing a service in a packet-switched network, comprising:
- receiving a request for a service from a customer device;
- determining an availability of the network to provide the requested service at a selected quality of service level wherein determining the availability includes:
- estimating a value of a front end metric wherein the front end metric is selected from a group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio and wherein the front end of the network includes a portion of the network between a digital subscriber line access multiplexer (DSLAM) and a gateway at a customer location;
- and
- estimating a value of a back end metric wherein the back end metric is selected from the group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio wherein the back end of the network includes a portion of the network between a video server and the DSLAM;
- and
- enabling the network to provide the service when the availability indicates an ability to provide the service at the selected quality of service level.
4 more elements
A quality of service server, comprising:
- a processor;
- computer readable storage, accessible to the processor, the storage including processor executable program instructions for providing a network service, the program instructions including instructions to:
- receive a request from a customer equipment for a service over a packet-switched network;
- determine an availability of the network to provide the service at a selected quality of service level including a set of instructions to:
- estimate a value of a front end metric indicative of a metric for a front end of the network wherein the front end metric is selected from a group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio and wherein the front end of the network includes a portion of the network between a digital subscriber line access multiplexer (DSLAM) and a gateway at a customer location;
- and
- estimate a value of a back end metric indicative of a metric for a back end of the network wherein the back end metric is selected from the group consisting of mean packet transfer delay, delay jitter, packet loss ratio, and packet error ratio wherein the back end of the network includes a portion of the network between a video server and the DSLAM;
- and
- provide the service when the availability indicates the selected quality of service level.
