Method, apparatus, and system for diagnosing route in network based on diameter protocol

摘要

A method, system, and apparatus for diagnosing a route in a network based on a Diameter protocol are provided. The method includes the following steps. A source Diameter node generates a diagnosis message according to diagnosis parameters, and sends the diagnosis message. An intermediate Diameter node adds diagnosis information thereof to the diagnosis message after receiving the diagnosis message, and forwards the diagnosis message until the diagnosis message is forwarded to a Diameter server capable of processing the diagnosis message or a Diameter node incapable of forwarding the diagnosis message. The Diameter server capable of processing the diagnosis message or the Diameter node incapable of forwarding the diagnosis message generates a response message of the diagnosis message, and sends the response message carrying diagnosis information thereof, information in the diagnosis message, and a response type. The intermediate Diameter node receiving the response message adds the diagnosis information thereof to the response message, and forwards the response message until the response message is forwarded to the source Diameter node. The source Diameter node parses the response message to obtain route related information.
