The method also includes 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. The method further includes determining, by the first Diameter message processor, a next-hop Diameter node for the Diameter message. 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, the Diameter message. The method further includes 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.

METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR SOURCE PEER CAPACITY-BASED DIAMETER LOAD SHARING
Methods, systems, and computer readable media for source peer capacity-based Diameter load sharing are disclosed. According to one aspect, the subject matter described herein includes a method for source peer capacity-based Diameter load sharing. A network element for processing Diameter messages received from a Diameter peer requests information regarding a Diameter message capacity requirement of the Diameter peer, receives information regarding the Diameter message capacity requirement of the Diameter peer, and uses the received information to load share the processing. In one embodiment, the network element is a Diameter signaling router having multiple message processors for processing Diameter messages, and the information regarding the Diameter message capacity requirement of the Diameter peer is used to load share Diameter message processing and/or Diameter connections among the multiple message processors.

METHODS, SYSTEMS AND COMPUTER READABLE MEDIA FOR PROVIDING PRIORITY ROUTING AT A DIAMETER NODE
Methods, systems, and computer readable media for providing priority routing at a Diameter node are disclosed. One exemplary method includes receiving, at a Diameter message processor associated with a DSR, a Diameter message from a first Diameter node. The method further includes assigning, at the Diameter message processor, a priority level indicator to the Diameter message. The method also includes routing the Diameter message with the priority level indicator to a second Diameter node. A second exemplary method includes receiving, at a Diameter message processor associated with a DSR, a Diameter message that includes a priority level indicator from a first Diameter node. The second method further includes applying, at the Diameter message processor, a routing action to the Diameter message based at least in part on the priority level indicator contained in the Diameter message.

Methods, systems, and computer readable media for providing origin routing at a Diameter node are disclosed. One exemplary method includes receiving, at a Diameter message processor associated with a DSR, a Diameter message from a first Diameter node. The method further includes accessing, using the Diameter message processor, Diameter peer routing information that includes Diameter origination information to determine a second Diameter node that is a peer of the DSR and to which the Diameter message is to be forwarded. The method also includes forwarding the Diameter message to the determined second Diameter node.

According to one aspect, the subject matter described herein includes a method for providing Diameter protocol harmonization. The method includes steps occurring at a Diameter node. The method further includes determining a first Diameter protocol associated with received Diameter information that is to be sent to a destination. The method also includes determining a second Diameter protocol associated with the destination. The method further includes harmonizing the received Diameter information such that the harmonized Diameter information is compatible with the second Diameter protocol. The method also includes providing the harmonized Diameter information to the destination.
