Abstract
The application relates to the transport of SS7 signaling over an Internet Protocol based network and in particular to the routing of SS7 Signaling Network Management SSNM Messages such as Destination Unavailable DUNA and Signalling Congestion SCON by a SIGTRAN relay node. The SSNM messages are checked against a so-called 'validation rule', which either specifies a list of allowed affected point codes or a threshold rate of SSNM messages with the same affected point code. If the SSNM message is 'valid' it is sent to a so-called “broadcast domain” which comprise nodes such as signaling endpoints or component of one or more application servers.
