Methods, systems, and computer readable media for selective diameter topology hiding

A method for selective Diameter topology hiding, the method comprising:

• at a Diameter agent including a Diameter topology hiding module (THM):
• receiving, from a first Diameter node in a first service provider network, a first Diameter signaling message including Diameter topology information;
• determining a trust relationship between the first service provider network and a second service provider network to which the first Diameter signaling message is addressed;
• in response to determining that the trust relationship requires at least some level of topology hiding, determining a topology hiding type based on the first Diameter signaling message;
• and
• modifying, based on the topology hiding type, the Diameter topology information included in the first Diameter signaling message to hide at least some of the Diameter topology information.

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

• at a Diameter agent including a Diameter topology hiding module (THM):
• receiving, from a first Diameter node in a first service provider network, a first Diameter signaling message including Diameter topology information;
• determining a trust relationship between the first service provider network and a second service provider network to which the first Diameter signaling message is addressed;
• in response to determining that the trust relationship requires at least some level of topology hiding, determining a topology hiding type based on the first Diameter signaling message;
• and
• modifying, based on the topology hiding type, the Diameter topology information included in the first Diameter signaling message to hide at least some of the Diameter topology information.
