Abstract

According to one aspect, the subject matter described herein includes a method of operating a Diameter signaling router (DSR) for routing Diameter messages. The method includes steps occurring at a DSR comprising a plurality of Diameter message processors, each configured to perform at least one Diameter function. The method also includes detecting, at a first of the plurality of Diameter message processors, a change in status relating to the at least one Diameter function. The method further includes communicating, by the first of the plurality of Diameter message processors and to a second of the plurality of Diameter message processors, an indication of the change in status.

Claims

1. A method of operating a Diameter signaling router (DSR) for routing Diameter messages, the method comprising:

at a DSR comprising a plurality of Diameter message processors, each configured to perform at least one Diameter function;

detecting, at a first of the plurality of Diameter message processors, a change in status relating to the at least one Diameter function; and

communicating, by the first of the plurality of Diameter message processors and to a second of the plurality of Diameter message processors, an indication of the change in status.

2. The method of claim 1 wherein the change in status includes at least one of a change in operational status of a message processor, a change in operational status of a Diameter layer, a change in operational status of a Diameter peer node, a change in connection status of a Diameter peer node, a change in operational status of a Diameter application, and a change in connection status of a Diameter application.

3. The method of claim 1 comprising, in response to detecting the change in status, updating at least one of a routing table associated with the DSR, a routing database associated with the DSR, and a routing data structure associated with the DSR.

4. The method of claim 1 wherein at least one of the plurality of Diameter message processors is a distinct message processor for one of:

implementing Diameter transport connections;

implementing Diameter routing;

or implementing Diameter applications.

5. The method of claim 1 wherein at least one of the plurality of Diameter message processors implements a layer for providing transport connections and a layer for performing Diameter routing.

6. The method of claim 1 wherein at least one of the plurality of Diameter message processors implements a layer for implementing transport connections, a layer for performing Diameter routing, and a layer for providing Diameter applications.

7. The method of claim 1 wherein the Diameter message processors are interconnected via either an internal communications network or an external communications network.

8. The method of claim 1 wherein at least one of the plurality of Diameter message processors comprises one of:

a distinct message processing module of a distributed computing platform;

a computing blade in a blade-based distributed computing platform;

a processing core element associated with a single or multi-core computing device; and

a virtual node instantiated on a single physical message processing/computing device.

9. The method of claim 1 wherein communicating an indication of the change in status comprises updating at least one of a message processor status database associated with the DSR, a message processor status table associated with the DSR, and a message processor status data structure associated with the DSR.

10. The method of claim 9 wherein the at least one of the message processor status database associated with the DSR, the message processor status table associated with the DSR, and the message processor status data structure associated with the DSR is configured to broadcast/multicast status information to at least one of the plurality of Diameter message processors.

11. The method of claim 9 wherein at least one of the plurality of Diameter message processors is configured to query the at least one of the message processor status database associated with the DSR, the message processor status table associated with the DSR, and the message processor status data structure associated with the DSR.

12. A system for routing Diameter messages, the system comprising:

a Diameter signaling router including;

first and second Diameter message processors, each for implementing at least one Diameter function,

wherein the first Diameter message processor is configured to detect a change in status relating to the at least one Diameter function and communicate, to the second Diameter message processor, an indication of the change in status.

13.
