Abstract

A method of configuring a network element in a transport network comprising interrogating components of the network element about their characteristic and exchanging information on characteristics of the network element and its components with neighboring network elements. The network element is configured based on the exchanged information.

Claims

1. A method of configuring a network element in a transport network comprising:

interrogating components of the network element about their characteristic;

saving the characteristics in an inventory module;

sending to a neighbour network element at least part of information stored in the inventory module;

receiving from the neighbour network element information about said neighbour network element; and

configuring at least one of said components based on the information received from the neighbour network element.

2. The method according to claim 1, further comprising interrogating a remote database to obtain information related to the characteristics of the components of the network element.

3. The method according to claim 1, further comprising repeating the steps of sending and receiving for other neighbour network elements, wherein the step of configuring comprises selecting configuration parameters from the information received from the neighbour network elements.

4. The method according to claim 1, further comprising determining topology of the transport network using the information received from the neighbour network element.

5. The method according to claim 1, further comprising configuring in the network element a maintenance entity point or a maintenance intermediate point using the information received from the neighbour network element.

6. The method according to claim 1, further comprising configuring in the network element synchronisation feeds and/or time slots and/or wavelength assignments and/or protection using the information received from the neighbour network element.

7. The method according to claim 1, further comprising sending implemented configuration settings to a network management system.

8. The method according to claim 1, wherein the steps of sending and receiving information use signalling over an in-band channel of the transport network.

9. A network element for use in a transport network, the network element comprising an inventory module communicatively coupled to a processor, the processor being communicatively coupled to components of the network element, wherein the inventory module is adapted to store information about the network element and said components of the network element, wherein said processor is adapted to send to a neighbour network element at least part of the information stored in the inventory module and to receive from the neighbour network element information about said neighbour network element, the network element further comprising an interface for communicating with the neighbour network element;

said processor being adapted to configure at least one of said components based on the information received from the neighbour network element.

10. The network element according to claim 9, wherein the network element further comprises a system controller for communicating between the processor and the components of the network element.

11. The network element according to claim 9, wherein the components of the network element are tributary card and/or line cards.

12. A transport network comprising a network element, the network element comprising an inventory module communicatively coupled to a processor, the processor being communicatively coupled to components of the network element, wherein the inventory module is adapted to store information about the network element and said components of the network element, wherein said processor is adapted to send to a neighbour network element at least part of the information stored in the inventory module and to receive from the neighbour network element information about said neighbour network element, the network element further comprising an interface for communicating with the neighbour network element;

said processor being adapted to configure at least one of said components based on the information received from the neighbour network element.
