Abstract

A system and method for reconfiguring a telecommunications network comprising a plurality of network elements is disclosed. The reconfiguration process begins by identifying a new configuration for the telecommunications network. Next, the process stores the new configuration with the old configuration for the telecommunications network. The system then identifies new connection information associated with the new configuration. The system then downloads the new connection information to the plurality of network elements. After the connection information has been downloaded, the connection information is stored with the old connection information at the plurality of network elements. Next, a message is broadcast to the plurality of network elements to activate the new configuration and deactivate the old configuration. The activation of the new connection information stored by the plurality of network elements occurs substantially simultaneously.

Claims

1. A method for reconfiguring a network wherein said network comprises a plurality of network elements which further comprise a plurality of network connections, said method comprising the steps of:

(1) identifying a new configuration for said network;

(2) identifying new connection information associated with said new configuration;

(3) downloading said new connection information to said plurality of network elements;

(4) broadcasting a message to said plurality of network elements; and

(5) activating said downloaded new connection information stored by said plurality of network elements substantially simultaneously in response to said broadcast message.

2. The method of claim 1, further comprising the step of verifying the validity of said new connection information.

3. The method of claim 2, further comprising the step of transmitting an alarm if said step of verifying determines said new connection information is invalid.

4. The method of claim 1, further comprising the step of transmitting a download successful message in response to said step of downloading.

5. The method of claim 1, wherein said step of activating further comprises the step of switching the network connections of said plurality of network elements.

6. A system for reconfiguring a network wherein said network comprises a plurality of network elements which further comprise a plurality of network connections, said system comprising:

(1) means for identifying a new configuration for said network;

(2) means for identifying new connection information associated with said new configuration;

(3) means for downloading said new connection information to said plurality of network elements;

(4) means for broadcasting a message to said plurality of network elements; and

(5) means for activating said downloaded new connection information stored by said plurality of network elements substantially simultaneously in response to said broadcast message.

7. The system of claim 6, further comprising means for verifying the validity of said new connection information.

8. The system of claim 7, further comprising means for transmitting an alarm if said step of verifying determines said new connection information is invalid.

9. The system of claim 6, further comprising means for transmitting a download successful message in response to said step of downloading.

10. The system of claim 6, wherein said means for activating further comprises the means for switching the network connections of said plurality of network elements.

11. A method for reconfiguring a network element in a network wherein the network comprises a plurality of network elements which further comprise a plurality of network connections, the method comprising:

receiving new connection information, wherein the new connection information defines new connections for the network element and is associated with a new configuration for the plurality of network elements;

storing the new connection information in a memory;

receiving a broadcast message, wherein the broadcast message contains a command to activate the new connection information for the network element; and

making new connections to the network element as defined by the new connection information in response to the command to activate the new connection information.

12. The method of claim 11, further comprises verifying the validity of the new connection information.

13. The method of claim 12, further comprises transmitting an alarm if the step of verifying determines that the new connection information is invalid.

14. The method of claim 11, further comprises transmitting a download successful message in response to the step of downloading.

15. The method of claim 11, wherein making new connections to the network element further comprises breaking old connections to the network element in conjunction with making new connections to the network element.

16. The method of claim 11, wherein the network element is a first network element, the new connection information is a first new connection information in the network, the memory is a first memory and the broadcast message is a first broadcast message, the method further comprises:

receiving second new connection information, wherein the second new connection information defines new connections for the second network element and is associated with the new configurational for the plurality of network elements;

storing the second new connection information in a second memory;

receiving a second broadcast message, wherein the second broadcast message has been broadcast in conjunction with the first broadcast message and contains a command to activate the second new connection information for the second network element; and

making new connections to the second network element as defined by the second new connection information in response to the command to activate the second new connection information.
