Abstract

A method for managing packet voice networks using a virtual switch approach and abstract information model approach is disclosed. A virtual switch object represents a virtual switch having a media gateway controller and one or more associated media gateways. User input specifies a configuration operation on the virtual switch and one or more parameter values. One or more configuration instructions are automatically issued to both the media gateway controller and the media gateway, resulting in configuring both the media gateway controller and the media gateway as specified in the user input. As a result, a user can configure or operate on a virtual switch as an atomic entity, for example, in a network management application, without involvement in complicated details of the actual network devices that provide a particular packet voice service.

1. A volatile or non-volatile computer-readable medium storing instructions for managing packet voice networks using a virtual switch approach, which instructions, when executed by one or more processors, cause:

creating and storing a virtual switch object, wherein the virtual switch object is an instantiation of a class and represents a virtual switch, in a packet-switched voice network, having a media gateway controller and one or more associated media gateways, wherein the virtual switch object comprises programmatic objects representing the media gateway controller, the one or more media gateways, and associations between the one or more media gateways and the media gateway controller;

receiving user input that specifies a configuration operation on the virtual switch and one or more parameters; and

automatically issuing one or more configuration instructions to both the media gateway controller and the media gateway that cause configuring both the media gateway controller and the media gateway as specified in the user input.

2. A volatile or non-volatile computer-readable medium as recited in claim 1, wherein:

the virtual switch object is created as part of a network management application computer program;

the network management application is communicatively coupled to an operational support system and to one or more element management systems; and

execution of the instructions by the one or more processors further causes issuing one or more configuration requests to one or more of the element management systems as part of the step of automatically issuing configuration instructions.

3. A volatile or non-volatile computer-readable medium as recited in claim 1, wherein:

the virtual switch object is created as part of a network management application computer program that generates a graphical user interface that displays an icon representation of the virtual switch; and

the step of receiving user input comprises receiving user input dragging the icon representation and dropping the icon representation in a data entry field.

4. A volatile or non-volatile computer-readable medium as recited in claim 3, wherein execution of the instructions by one or more processors further causes displaying the icon representation in an object holding area of the graphical user interface when the media gateway associated with the object is not then currently associated with a media gateway controller.

5. A volatile or non-volatile computer-readable medium as recited in claim 3, wherein the graphical user interface comprises a tree view of the virtual switch and each media gateway or media gateway controller associated therewith, a topology map of a network topology that includes the virtual switch, and an object holding area that displays un-associated network elements.

6. A volatile or non-volatile computer-readable medium as recited in claim 1, wherein configuration operation of the step of receiving user input is selected from among the set consisting of:

associate/disassociate a media gateway from a virtual switch;

add or remove or modify parameters of a primary rate interface (PRI) backhaul service;

add or remove or modify a trunk, a trunk group, routes, or route lists;

add or remove or modify a customer;

or turn up or tear down or modify service for a customer.

7. A volatile or non-volatile computer-readable medium as recited in claim 1, wherein the virtual switch object comprises programmatic objects representing:

a media gateway controller;

a media gateway;

associations between the media gateway and media gateway controller;

one or more connection termination points of the media gateway controller and the media gateway;

add a line with TDM endpoints and a CCS channel on the selected media gateway;

add a new trunk group at the media gateway controller and associate it with a customer;

add one or more trunks at the media gateway controller;

associate the trunks with a corresponding endpoint of the media gateway;

verify that a signaling backhaul connection has been set up;

set up a signaling backhaul connection if required;

set up a cross-connect between the CCS channel and the signaling backhaul connection at the media gateway, if required, as determined by the type of media gateway.

9. A volatile or non-volatile computer-readable medium as recited in claim 1, wherein:

the virtual switch object is created as part of a network management application computer program that is interfaced to an operational support system; and

the step of receiving user input comprises receiving user input from an interface to the operational support system that specifies a configuration operation on the virtual switch and one or more parameter values.

10. An apparatus for managing packet voice networks using a virtual switch approach, comprising:
