Methods, systems, and computer readable media for inter-diameter-message processor routing

A system for routing Diameter messages, the system comprising:

• a Diameter signaling router (DSR) including:
• first and second Diameter message processors, wherein the first Diameter message processor is configured to:
• receive, from a first Diameter node and via a first Diameter connection, a Diameter message;
• determine a next-hop Diameter node for the Diameter message;
• and
• communicate, to the second Diameter message processor, the Diameter message, and wherein the second Diameter message processor is configured to communicate to the next-hop Diameter node, via a second Diameter connection, the Diameter message, wherein the first Diameter message processor adds an inter-message processor routing tag identifier to the Diameter message before sending the message to the second Diameter message processor and wherein the second Diameter message processor uses the inter-message processor routing tag to identify the message as being directed to it and as not requiring another Diameter routing lookup.

A system for routing Diameter messages, the system comprising:

• a first Diameter node;
• a second Diameter node;
• and
• a Diameter signaling router (DSR), wherein the DSR appears to the first Diameter node as a first Diameter peer having a first Diameter identity and the DSR appears to the second Diameter node as a second Diameter peer having a second Diameter identity, the second Diameter identity and the first Diameter identity being different, wherein the DSR comprises a first Diameter message processor and a second Diameter message processor, wherein the first Diameter message processor adds an inter-message processor routing tag identifier to the Diameter message before sending the message to the second Diameter message processor and wherein the second Diameter message processor uses the inter-message processor routing tag to identify the message as being directed to it and as not requiring another Diameter routing lookup.

A non-transitory computer readable medium comprising computer executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• at a Diameter signaling router (DSR) comprising a plurality of Diameter message processors:
• receiving, by a first of the plurality of Diameter message processors and from a first Diameter node, a Diameter message, wherein the Diameter message is received via a first Diameter connection;
• determining, by the first Diameter message processor, a next-hop Diameter node for the Diameter message;
• communicating, by the first Diameter message processor and to a second of the plurality of Diameter message processors, the Diameter message;
• and communicating, by the second Diameter message processor and to the next-hop Diameter node, the Diameter message, wherein the Diameter message is communicated via a second Diameter connection, wherein the first Diameter message processor adds an inter-message processor routing tag identifier to the Diameter message before sending the message to the second Diameter message processor and wherein the second Diameter message processor uses the inter-message processor routing tag to identify the message as being directed to it and as not requiring another Diameter routing lookup.
