Configuration file framework to support high availability schema based upon asynchronous checkpointing
View Patent ↗In various exemplary embodiments, a method and related system for configuration file management in a network element comprise one or more of the following: upon initialization of the network element, reading a first configuration file that is in a character-encoded format; for each application process, translating the first configuration file into a plurality of non-character-encoded configuration files; configuring each application process based on the respective plurality of non-character-encoded configuration files; modifying, in real-time, at least one of the non-character-encoded configuration files; and merging each of the non-character-encoded configuration files into a second configuration file that is in a character-encoded format.
1. A method for configuration file management in a network element that executes a plurality of application processes, the method comprising:
upon initialization of the network element, reading a first configuration file that is in a character-encoded format from a non-volatile memory device;
for each application process, translating the first configuration file into a plurality of non-character-encoded configuration files;
storing the plurality of non-character-encoded configuration files in a dynamic random access memory;
configuring each application process based on the respective plurality of non-character-encoded configuration files;
modifying, in real-time, at least one of the non-character-encoded configuration files; and
merging each of the non-character-encoded configuration files into a second configuration file that is in a character-encoded format.
2. The method for configuration file management in the network element according to claim 1 , wherein the character-encoded format is an American Standard Code for Information Interchange (ASCII) format.
3. The method for configuration file management in the network element according to claim 1 , wherein the non-character-encoded format is a binary format.
4. The method for configuration file management in the network element according to claim 1 , further comprising:
storing the first configuration file in a non-volatile memory in the network element.
5. The method for configuration file management in the network element according to claim 4 . wherein the non-volatile memory is a flash memory device.
6. The method for configuration file management in the network element according to claim 1 , wherein the step of translating the first configuration file into a plurality of non-character-encoded configuration files is done per object type.
7. The method for configuration file management in the network element according to claim 1 , further comprising:
requesting, via inter-process communication, that each application process create a temporary copy of the respective non-character-encoded configuration files.
8. The method for configuration file management in the network element according to claim 1 , further comprising:
forwarding the second configuration file to a network operator for editing.
9. The method for configuration file management in the network element according to claim 1 , wherein the step of merging occurs at substantially a same time as the execution of the plurality of application processes.
10. A network element for configuration file management in a high-availability, embedded system, the network element comprising:
a non-volatile memory device storing a first configuration file in a character-encoded format;
a dynamic random access memory; and
a processor configured to execute a plurality of application processes, read the first configuration file upon receiving an initialization signal, for each application process, translate the first configuration file into a plurality of non-character-encoded configuration files, store the plurality of non-character-encoded configuration files on the dynamic random access memory, configure each application process based on the respective plurality of non-character-encoded configuration files, modify, in real-time, at least one of the non-character-encoded configuration files, and merge each of the non-character-encoded configuration files into a second configuration file that is in a character-encoded format.
11. The network element according to claim 10 , wherein the character-encoded format is an American Standard Code for Information Interchange (ASCII) format.
12. The network element according to claim 10 , wherein the non-character-encoded format is a binary format.
13. The network element according to claim 10 , wherein the non-volatile memory device is a flash memory device.
14. The network element according to claim 10 , wherein the processor translates the first configuration file into a plurality of non-character-encoded configuration files per object type.
15. The network element according to claim 10 , wherein the processor is further configured to request, via inter-process communication, that each application process create a temporary copy of the respective non-character-encoded configuration files.
16. The network element according to claim 10 , wherein the processor is further configured to forward the second configuration file to a network operator for editing.
17. The network element according to claim 10 , wherein the non-character-encoded format is a decimal format.
18. The network element according to claim 10 , wherein the non-character-encoded format is a hexadecimal format.
19. The network element according to claim 10 , wherein the non-volatile memory device is a hard drive.
