Abstract

A system and method for time synchronized reconfiguration of a telecommunications network is disclosed. The method first identifies a new configuration for the telecommunications network. After the configuration has been identified, the new configuration is stored with the old configuration for the telecommunications network. Next, the new connection information associated with the new configuration is identified. After the new connection information is identified it is downloaded to the network elements. The new connection information is stored with the old connection information at the network elements. Next, the clocks of the network elements are synchronized through an external clock. An activation time is then downloaded to the network elements specifying an activation time for the new connection information. After the activation time is downloaded, the new connection information is activated at the specified downloaded activation time.

Claims

1. A method for time based reconfiguration of a network, wherein said network comprises a plurality of network elements, 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) downloading an activation time to said plurality of network elements specifying an activation time for said new connection information; and

(5) activating said downloaded new connection information stored by said plurality of network elements at said activation time.

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 time based reconfiguration of a network, wherein said network comprises a plurality of network elements, 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 downloading an activation time to said plurality of network elements specifying an activation time for said new connection information; and

(5) means for activating said downloaded new connection information stored by said plurality of network elements at said activation time.

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.
