A method for providing Diameter network management information in a communications network, the method comprising: at a Diameter signaling router, DSR: determining whether successful Diameter communications are available with a first Diameter application (100, 200); in response to determining that successful Diameter communications are not available with the first Diameter application (100, 200), generating a first Diameter network management message, DNMM, indicating that successful Diameter communications are not available with the first Diameter application (100,200); and sending the first DNMM to a plurality of peer Diameter signalling routers, DSRs (102A-D);; wherein the first Diameter application (100, 200) is provided by a Diameter node (100, 200) other than said DSR and said plurality of peer DSRs (102A-D) node; and wherein the method further comprises: at the plurality of peer DSRs: receiving the first DNMM; and in response to receiving the first DNMM, determining a different path for sending a Diameter message towards the first Diameter application (100, 200) and sending the Diameter message to the first Diameter application (100, 200) via the different path. at a Diameter signaling router, DSR: determining whether successful Diameter communications are available with a first Diameter application (100, 200); in response to determining that successful Diameter communications are not available with the first Diameter application (100, 200), generating a first Diameter network management message, DNMM, indicating that successful Diameter communications are not available with the first Diameter application (100,200); and sending the first DNMM to a plurality of peer Diameter signalling routers, DSRs (102A-D);; wherein the first Diameter application (100, 200) is provided by a Diameter node (100, 200) other than said DSR and said plurality of peer DSRs (102A-D) node; and wherein the method further comprises: determining whether successful Diameter communications are available with a first Diameter application (100, 200); in response to determining that successful Diameter communications are not available with the first Diameter application (100, 200), generating a first Diameter network management message, DNMM, indicating that successful Diameter communications are not available with the first Diameter application (100,200); and sending the first DNMM to a plurality of peer Diameter signalling routers, DSRs (102A-D);; wherein the first Diameter application (100, 200) is provided by a Diameter node (100, 200) other than said DSR and said plurality of peer DSRs (102A-D) node; and wherein the method further comprises: at the plurality of peer DSRs: receiving the first DNMM; and in response to receiving the first DNMM, determining a different path for sending a Diameter message towards the first Diameter application (100, 200) and sending the Diameter message to the first Diameter application (100, 200) via the different path. receiving the first DNMM; and in response to receiving the first DNMM, determining a different path for sending a Diameter message towards the first Diameter application (100, 200) and sending the Diameter message to the first Diameter application (100, 200) via the different path.
