Generic persistence in a diameter routing agent

1. A method performed by a Diameter Routing Agent (DRA) for processing a Diameter message, the method comprising:

receiving a first Diameter message at the DRA;

evaluating a first rule, comprising accessing data from a generic binding context object, wherein a context object is an instantiated data structure used to store and access data related to whatever is modifying it, comprising:

locating a record associated with a key specified by the first rule, and

retrieving the data from the record; and

transmitting a message based on the evaluation of the first rule; and

after transmitting the message:

determining that a timestamp associated with the record indicates that the record is older than a record retention threshold; and

deleting the record based on the record being older than a record retention threshold.

2. The method of claim 1 , further comprising, before evaluating the first rule:

receiving a second Diameter message at the DRA; and

evaluating a second rule, comprising accessing the generic binding context object, comprising storing the data in the record associated with the key.

3. The method of claim 2 , further comprising, after storing the data in the record, transmitting the data to at least one other device for storage in a redundant copy of the record.

4. The method of claim 2 , wherein storing the data in the record comprises writing the data to a portion of volatile memory associated with the record.

5. The method of claim 1 , wherein:

the key comprises a key label and key data, and

the record is associated with both the key label and the key data.

6. The method of claim 1 , wherein the record comprises a plurality of values and retrieving the data from the record comprises:

locating a value of the plurality of values associated with a value label specified by the first rule, wherein the value includes the value label and value data; and

retrieving the value data from the value.

7. A diameter routing agent (DRA) for processing a Diameter message, the DRA comprising:

a network interface;

a volatile memory; and

a processor in communication with the memory, the processor being configured to:

receive a first Diameter message via the network interface; evaluate a first rule, comprising accessing data from a generic binding context object, wherein a context object is an instantiated data structure used to store and access data related to whatever is modifying it, comprising:

locating a record associated with a key specified by the first rule, and

retrieving the data from the record; and

transmit a message via the network interface based on the evaluation of the first rule; and

after transmitting the message:

determine that a timestamp associated with the record indicates that the record is older than a record retention threshold; and

delete the record based on the record being older than a record retention threshold.

8. The DRA of claim 7 , wherein the processor is further configured to, before evaluating the first rule:

receive a second Diameter message at the DRA; and

evaluate a second rule, comprising accessing the generic binding context object, comprising storing the data in the record associated with the key.

9. The DRA of claim 8 , wherein the processor is further configured to, after storing the data in the record, transmitting the data to at least one other device for storage in a redundant copy of the record.

10. The DRA of claim 8 , wherein, in storing the data in the record, the processor is configured to write the data to a portion of the volatile memory associated with the record.

11. The DRA of claim 7 , wherein:

the key comprises a key label and key data, and

the record is associated with both the key label and the key data.

12. The DRA of claim 7 , wherein the record comprises a plurality of values and, in retrieving the data from the record, the processor is configured to:

locate a value of the plurality of values associated with a value label specified by the first rule, wherein the value includes the value label and value data;

retrieve the value data from the value.

13. A non-transitory machine-readable storage medium encoded with instructions for execution by a Diameter Routing Agent (DRA) for processing a Diameter message, the medium comprising:

instructions for receiving a first Diameter message at the DRA;

instructions for evaluating a first rule, comprising accessing data from a generic binding context object, wherein a context object is an instantiated data structure used to store and access data related to whatever is modifying it, comprising:

instructions for locating a record associated with a key specified by the first rule, and

instructions for retrieving the data from the record; and

instructions for transmitting a message based on the evaluation of the first rule and

after transmitting the message:

instructions for determining that a timestamp associated with the record indicates that the record is older than a record retention threshold; and

instructions for deleting the record based on the record being older than a record retention threshold.

14. The non-transitory machine-readable storage medium of claim 13 , further comprising:

instructions for receiving a second Diameter message at the DRA; and

instructions for evaluating a second rule, comprising accessing the generic binding context object, comprising storing the data in the record associated with the key.

15. The non-transitory machine-readable storage medium of claim 14 , further comprising instructions for transmitting the data to at least one other device for storage in a redundant copy of the record.

16. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions for storing the data in the record comprise instructions for writing the data to a portion of volatile memory associated with the record.

17. The non-transitory machine-readable storage medium of claim 13 , wherein:

the key comprises a key label and key data, and

the record is associated with both the key label and the key data.

18. The non-transitory machine-readable storage medium of claim 13 , wherein the record comprises a plurality of values and the instructions for retrieving the data from the record comprise:

instructions for locating a value of the plurality of values associated with a value label specified by the first rule, wherein the value includes the value label and value data;

instructions for retrieving the value data from the value.
